Description

TECHNICAL FIELD The present invention relates to a method for producing a molded product of synthetic resin which is nonflammable and does not self-ignite. In other words, a group of metal-bonded metal nanoparticles is deposited on the surface of the molding material, and this group of molding material is dispersed in a liquid organic compound to form a suspension. When this suspension is filled in a molding machine or a mold and heat and pressure are applied at the same time, after the organic compound is vaporized, a collection of metal-bonded metal nanoparticles covers the compression-deformed molding material, The molding materials, which are compressed and deformed by the metallic bond of the nanoparticles, are bonded to each other to produce a molded body. All the compression-deformed molding materials constituting the molded body are covered with an airtight coating composed of a collection of metal-bonded metal nanoparticles, and the molded body has the property of being nonflammable and not self-igniting.

A technique close to the present invention is a method for producing a flame-retardant synthetic resin. A flame-retardant synthetic resin is called a flame-retardant synthetic resin, and the flame-retardant properties include flame retardancy, self-extinguishing property, and combustion retardation. However, since the synthetic resin is composed of an organic material and the skeleton of the molecule is carbon and hydrogen as the main constituent elements, the synthetic resin has a property of being easily burned. Therefore, by introducing an element called a so-called hetero atom such as chlorine or nitrogen into the skeleton of the molecule of the synthetic resin (see, for example, Patent Document 1), or a halogen compound, a phosphorus compound, which has a flame retardant effect, Alternatively, an inorganic compound or the like is added (see, for example, Patent Documents 2 and 3) to make the synthetic resin difficult to burn.
However, due to the introduction of chlorine element or the addition of a halogen compound, it is necessary to eliminate the fear that a toxic gas is generated due to the combustion of the synthetic resin. Further, the addition of the phosphorus compound causes a new problem that the hydrolyzability of the synthetic resin advances and a problem that the mold is contaminated. Furthermore, since the thermal decomposition temperature of the inorganic compound is low, a new problem that cannot be applied to synthetic resins having a high molding temperature occurs.
On the other hand, as a synthetic resin having the highest flame retardance, there is a polyvinyl chloride resin PVC in which 50 wt% or more of the skeleton of the molecule is chlorine, and a wire coating material, a building material, in which safety in a fire is important. Widely used for rain gutters, ventilation pipes, flooring materials and sashes. Further, one of the indices of flame retardancy is an oxygen index that means the oxygen concentration required for burning, and since the oxygen index of PVC exceeds 21% of the oxygen concentration in the atmosphere, it has self-extinguishing properties. Furthermore, since PVC has a lower heat radiation amount when burned than other synthetic resins, it has a property of being less likely to spread fire than other materials even when burned.
However, PVC is weak in organic solvents, softens at 65 to 85° C., and becomes brittle at −20° C., and therefore has a narrow temperature range in which it can be used, and is weak in impact force, so that application of the product is significantly limited.
For this reason, there is a demand for a versatile synthetic resin flame retarding technique that can make the synthetic resin flame-retardant regardless of the material of the synthetic resin and does not cause new problems or problems in the flame-retardant treatment.

In the process of burning the synthetic resin, first, the synthetic resin is heated, then the polymer is thermally decomposed, and further self-ignited to start combustion, and a flame is propagated. It should be noted that self-ignition means that the substance burns out, and when the heat energy required for ignition is obtained, that is, when the temperature is raised above the ignition point, the combustible substance burns in the atmosphere in which oxygen gas exists. put out. In the heating process, the synthetic resin is used in the scene where nonflammability or flame retardancy is required, and thus all the synthetic resins are heated. Further, all the polymers constituting the synthetic resin are thermally decomposed by heating.
On the other hand, the thermal decomposition reaction of the polymer is greatly different between the atmosphere in which oxygen gas exists and the nitrogen gas atmosphere. That is, in an atmosphere in which oxygen gas exists, thermal decomposition due to an oxidation reaction continuously occurs, and the oxidation reaction is accompanied by heat generation, so that the thermal decomposition of the polymer is accelerated. Further, the exothermic phenomenon gives thermal energy to the thermally decomposed combustible gas, and when the combustible gas is heated to a temperature higher than the ignition point, it self-ignites to start combustion, and in the presence of oxygen gas, the synthetic resin Burning continues. On the other hand, in a nitrogen gas atmosphere, an oxidation reaction does not occur, but thermal decomposition accompanied by an endothermic reaction continuously occurs. Since the thermal decomposition is an endothermic reaction, the thermal decomposition reaction in the nitrogen gas atmosphere is delayed, and the thermal decomposition proceeds remarkably on the high temperature side as compared with the atmosphere in which oxygen gas exists. On the other hand, even in a nitrogen gas atmosphere, if a combustible gas is generated by thermal decomposition and the combustible gas moves to the atmosphere and is heated above the ignition point, the combustible gas self-ignites and causes a fire. Make a starting point.
On the other hand, if the molding material that constitutes the molded body of synthetic resin, that is, the individual pellets or individual powder particles can be covered with the airtight coating that shuts off the external environment, it is equivalent to the volume of the individual molding material. The polymer is thermally decomposed in a narrow area. For this reason, the flammable gas that is initially generated by thermal decomposition is confined in a narrow region covered with an airtight film, and the partial pressure occupied by the flammable gas in the narrow region gradually increases and its temperature rises. At the saturated pressure in, the thermal decomposition stops. Therefore, the thermal decomposition does not proceed unless thermal energy larger than that in the open nitrogen atmosphere is applied. Further, since 1 mol of the combustible gas occupies a volume of 22.4 liters, when a very small amount is pyrolyzed, the saturated pressure of the combustible gas at that temperature is reached in a confined narrow region. Further, in the flammable gas generated in the second and subsequent times by the thermal decomposition, the first combustible gas is already confined, so that the thermal decomposition does not proceed unless further large thermal energy is supplied. As a result, the thermal decomposition of the polymer shifts to a much higher temperature side than the thermal decomposition in the nitrogen atmosphere, and the thermal decomposition proceeds beyond the ignition point of the combustible gas. As a result, the molded body of synthetic resin does not self-ignite due to thermal decomposition of the polymer due to heating, and does not form a starting point of fire. Furthermore, if the airtight coating has a certain bond strength, the gas pressure trapped inside the coating does not destroy the coating. As a result, oxygen gas is not supplied to the molding material, and the molding has incombustibility.
As explained above, if all molding materials that make up a synthetic resin molded body are covered with an airtight coating having a certain bond strength, the molded body will, first of all, be self-igniting, which is the starting point of a fire. Does not happen. Secondly, since it is nonflammable, it does not generate toxic gas, combustible gas, and black smoke due to combustion, and the fire does not spread. This opens up new applications for synthetic resin moldings.

A synthetic resin molded body is obtained by filling a molding machine or a mold with a group of molding materials made of powder or granules, heating the group of molding materials to melt or soften, and further applying heat and compression force. In addition, the molten or softened molding material is directly bonded and then cooled to produce a molding. Therefore, the following five problems occur in order to realize the molded body having the nonflammability and the property of not self-igniting described in the third paragraph. First, the molding material is covered with a substance that forms an airtight coating that blocks the outside world. When this group of molding materials is filled in a molding machine or a mold and heat and compression force are applied simultaneously, secondly, the substance forming the film changes into an airtight film having a certain bonding strength, and Third, all the molding materials are covered with an airtight coating, and fourth, the molding materials are bonded to each other through the airtight coating to form a molded body. Fifth, no vacuoles are formed inside the molded body. As a result, even if the molded body is exposed to a high temperature during a fire, the thermal expansion of the vacuoles does not occur and the airtight coating is not destroyed. As a result, even if exposed to a high temperature during a fire, all the molding materials that make up the molded body are shielded from the outside world and the supply of oxygen gas is cut off. Maintains the property of not igniting.
If a molded body can be manufactured by solving these five problems and the airtight coating can be made of metal, the molding material is shielded from the outside by the metal coating, and the molded body composed of a collection of molding materials is made of metal. Combines heat resistance, metal conductivity, and heat conductivity. As a result, firstly, the molded body has the property of being nonflammable, not self-igniting, and the heat resistance of metals. Therefore, even if the molded body is exposed to high temperature, it does not burn, so that no gas consisting of toxic gas such as hydrogen chloride and combustible gas and black smoke are generated. Therefore, in the event of a fire, various disasters due to the combustion of synthetic resin products do not occur. Secondly, a new application is expanded to a molded body of synthetic resin having a metal property that is lighter than metal. For example, according to a molding method, a molded body can be manufactured as a shield base material that reflects electromagnetic waves, a heat dissipation base material that releases heat, an antistatic base material that does not charge static electricity, and the like. Furthermore, thirdly, since the existing molding material made of various synthetic resins is covered with the airtight coating, a molded body can be manufactured by the conventional molding method, and the problems caused by changing the composition of the molding material described in the second paragraph. And no problems occur. Further, it can be manufactured at a low cost like the conventional molded body.
As described above, if the above-mentioned five problems can be solved, the molded product of the synthetic resin is imparted with epoch-making properties, whereby epoch-making new applications can be opened up for the synthetic resin.

A method for producing a suspension in which the surface of the molding material of the synthetic resin according to the present invention is covered with a group of metal nanoparticles bound to a metal and the group of molding materials is dispersed in a liquid organic compound,
A metal compound that deposits a metal by thermal decomposition is dispersed in alcohol to prepare an alcohol dispersion liquid in which the metal compound is dispersed in alcohol in a molecular state, and the first property of dissolving or mixing in the alcohol and the viscosity of the alcohol An organic compound having four properties: a second property that is 20 times higher than the viscosity of, a third property that the melting point is lower than 20° C., and a fourth property that the boiling point is higher than the thermal decomposition temperature of the metal compound. A compound is mixed with the alcohol dispersion liquid, the organic compound is dissolved or mixed in the alcohol, and a mixed liquid in which the organic compound is uniformly mixed with the alcohol dispersion liquid is prepared. A mixture of resin molding materials is mixed to form a mixture in which the liquid mixture has a thickness corresponding to the viscosity of the liquid mixture and adheres to the molding material, after which the alcohol is vaporized from the mixture, whereby A group of fine crystals of the metal compound is deposited on the surface of the molding compound, a group of molding materials deposited on the surface of the fine crystals of the metal compound is a first suspension dispersed in the organic compound. is produced, further heat treatment of the suspension of the first, the fine crystals of the metal compound is thermally decomposed, the nanoparticles of the particulate metal is deposited simultaneously on the surface of the molding material, adjacent said granular Of the metal nanoparticles bound to each other are metal-bonded to each other, and the collection of metal-bonded metal nanoparticles covers the surface of the molding material, thereby covering the metal-bonded metal nanoparticles. A second suspension in which the organic compound is dispersed in the organic compound, and the surface of the synthetic resin molding material is covered with a group of metal-bonded metal nanoparticles. A method for producing a suspension, in which a suspension in which a liquid organic compound is dispersed is produced.

That is, when the five treatments in the present manufacturing method are continuously performed, a collection of metal-bonded metal nanoparticles is deposited on the surface of the molding material, and the collection of the molding material is dispersed in the liquid organic compound as a second A suspension is produced. Evaporation of the organic compound from the second suspension will cover all the molding material with a collection of metal-bonded metal nanoparticles. The aggregate of metal-bonded metal nanoparticles forms a coating having a certain bonding strength, and the coating has an airtight property in which the molding material is shielded from the external environment. As a result, a molded body that solves the first problem described in paragraph 5 is manufactured.
That is, first, when a metal compound is dispersed in alcohol, the metal compound is dispersed in alcohol in a molecular state, and the metal raw material is liquefied. Second, when the organic compound is mixed with the alcohol dispersion, the organic compound is dissolved or miscible in the alcohol, so that the organic compound is uniformly mixed with the alcohol dispersion of the metal compound to form a mixed solution. Thirdly, when a mixture of synthetic resin molding materials is mixed with the mixed solution, the viscosity of the organic compound is 20 times higher than that of alcohol, so the mixed solution adheres to the molding material with a thickness according to the viscosity of the mixed solution. Then, a mixture composed of a collection of molding materials to which the mixed liquid is attached is formed. Fourthly, when alcohol is vaporized from the mixture, the metal compound is dispersed in the alcohol but not in the organic compound, so that fine crystals of the metal compound are simultaneously precipitated on the surface of the molding material. As a result, a cluster of fine crystals of the metal compound is deposited on the surface of the molding material, and the cluster of the molding material is dispersed in a liquid organic compound to produce a first suspension. Fifthly, when the first suspension is heat-treated to thermally decompose the metal compound, granular metal nanoparticles having a size of 40-60 nm corresponding to the size of the fine crystals of the metal compound become Precipitates simultaneously on the surface. Since metal nanoparticles are deposited in an active state without impurities, adjacent metal nanoparticles are metal-bonded to each other at the contacting site, and a collection of metal-bonded metal nanoparticles is deposited on the surface of the molding material. A second suspension is created in which this mass of molding material is dispersed in a liquid organic compound. It should be noted that the metal nanoparticles do not react with the organic compound, and after forming a group of metal-bonded metal nanoparticles, form a second suspension together with the organic compound as a stable group of metal nanoparticles. .. In addition, since the organic compound does not have hygroscopicity, the collection of metal-bonded metal nanoparticles shielded from the outside by the liquid organic compound does not change with time. Thus, when the organic compound is vaporized from the second suspension, all the molding material is covered with a collection of metal-bonded metal nanoparticles. Since the collection of metal-bonded metal nanoparticles forms a laminated structure in which metal nanoparticles are stacked to cover the molding material, the collection of metal-bonded metal nanoparticles has a certain bonding strength. Also, an airtight film is formed to cover the molding material. This solves the first problem in paragraph 5.
Further, by changing the viscosity and the mixing ratio of the organic compound in the second suspension, and further changing the mixing ratio of the molding material, the slipperiness of the molding material in the second suspension and the second suspension It's toughness changes freely. Furthermore, if the boiling point of the organic compound is changed, the slipperiness of the molding material in the second suspension and the second suspension can be improved when the molded body is processed by applying heat and pressure to the second suspension. The viscosity of the suspension can be freely changed and is not restricted by the molding machine when processing the molded body.
The thermoplastic resin molding material and a part of the thermosetting resin molding material are pellets having a length of about 2 to 3 mm, which is five orders of magnitude larger than the metal nanoparticles. The remaining thermosetting resin molding material is a powder having a particle size of several tens of μm or more, which is three or more digits larger than the metal nanoparticles. Therefore, the metal nanoparticles, which are smaller than the molding material by three orders of magnitude or more, are metal-bonded to form a collection of metal nanoparticles, which are deposited on the surface of the molding material.
In the thermal decomposition reaction of a metal compound, the metal compound is first decomposed into a metal and an inorganic or organic substance. Next, the inorganic or organic substance is vaporized while taking heat of vaporization, and after vaporization is completed, metal is deposited and the thermal decomposition reaction is completed. This deposited metal contains no impurities.
In addition, the raw material in this manufacturing method consists of a metal compound which deposits a metal by thermal decomposition, an alcohol, and an organic compound having a high boiling point, all of which are general-purpose industrial chemicals. Further, the treatment in the present production method is firstly a treatment of dispersing a metal compound in alcohol, a second treatment of mixing an organic compound in an alcohol dispersion, and a third gathering of a synthetic resin molding material in the mixture. Of the mixture, the fourth step of vaporizing the alcohol from the mixture, and the fifth step of heat-treating the first suspension. Two suspensions are produced. Therefore, the second suspension can be manufactured in large quantities at a very low cost.
On the other hand, there is a temperature difference between the boiling point of alcohol and the boiling point of the inorganic or organic substance generated by the thermal decomposition of the metal compound. Can be collected individually.

That is, the complex composed of the inorganic metal compound in the method for producing the present suspension undergoes thermal decomposition at a relatively low temperature of 180 to 220° C. in the reducing atmosphere to deposit a metal. Further, it is dispersed in methanol, which is the most general-purpose alcohol, at a ratio close to 10% by weight. Therefore, the complex composed of the inorganic metal compound is a raw material for producing the suspension in the method for producing the suspension described in the sixth paragraph.
That is, cutting ligand consisting of molecules or inorganic ions inorganic material, a complex of an inorganic metal compound with a metal complex ion coordinated to the metal ion, the heat treatment in a reducing atmosphere, the first coordination bond portion And decomposed into inorganic substances and metals. When the temperature is further raised, the inorganic substance takes away the heat of vaporization and is vaporized, and the metal is deposited after the vaporization of all the inorganic substances is completed. That is, of the ions forming the complex, the metal ion located in the center of the molecule is the largest. Therefore, the distance between the metal ion and the ligand is the longest. Therefore, when the complex is heat-treated in a reducing atmosphere, the coordination bond portion where the metal ion binds to the ligand is first divided, and decomposed into a metal and an inorganic substance. When the temperature further rises, the inorganic substance takes away the heat of vaporization and is vaporized, and the metal is deposited after the vaporization is completed. At this time, since the inorganic substance has a low molecular weight, the vaporization of the inorganic substance is completed at a low temperature of 180 to 220° C. according to the molecular weight of the inorganic substance. As such a complex, a complex composed of an inorganic metal compound having an ammine metal complex ion in which ammonia NH ₃ serves as a ligand to form a coordinate bond with a metal ion, chlorine ion Cl ⁻ , or chlorine ion Cl ⁻ and ammonia NH. _A complex composed of an inorganic metal compound having a chlorometal complex ion which forms a ligand with ₃ and forms a coordinate bond with a metal ion, and a cyano metal with a cyano group CN ^{− serving} as a ligand ion and forms a coordinate bond with a metal ion.

There is a complex composed of an inorganic metal compound having an iodo metal complex ion that forms a child ion and coordinates-bonds to a metal ion. Further, such a complex composed of an inorganic metal compound having a small molecular weight is a metal complex having a metal complex ion that is easy to synthesize and is the cheapest.
In addition, the first property of being dissolved or miscible in methanol with aromatic carboxylic acid esters, glycols, glycol ethers or glycerin in the method for producing the present suspension, and the viscosity is 20 times or more than that of meta-nol. There is an organic compound which has a high second property, a third property having a melting point lower than 20° C., and a fourth property having a boiling point higher than the thermal decomposition temperature of a complex composed of an inorganic metal compound. All such organic compounds are general-purpose industrial chemicals. Therefore, such an organic compound is an inexpensive raw material for producing a suspension in the method for producing a suspension described in the sixth paragraph.
Therefore, when any one of the above-mentioned organic compounds is mixed with the methanol dispersion liquid of the complex composed of the inorganic metal compound, the complex and the organic compound are uniformly mixed in a molecular state. When a mixture of synthetic resin molding materials is mixed with this mixed solution to form a mixture, the viscosity of the organic compound is 20 times or more higher than the viscosity of methanol, so that the mixed solution has a thickness corresponding to the viscosity of the mixed solution. Adhere to the surface of. After that, when methanol is vaporized from the mixture, the complex is dispersed in methanol but not in the organic compound, so that fine crystals of the complex are simultaneously precipitated on the surface of the molding material. As a result, a first suspension is produced in which the cluster of molding material in which the cluster of fine crystals of the complex is deposited is dispersed in the liquid organic compound. When this first suspension was heat-treated and the complex was thermally decomposed, granular metal nanoparticles having a size of 40-60 nm corresponding to the size of fine crystals of the complex were simultaneously formed on the surface of the molding material. To deposit. Since the metal nanoparticles are deposited in an active state without impurities, adjacent metal nanoparticles are metal-bonded to each other at the contacting site, and a group of metal-bonded metal nanoparticles are deposited on the surface of the molding material. A second suspension is produced in which the mass is dispersed in a liquid organic compound. Therefore, the complex, methanol, and the organic compound in the method for producing the suspension are the first inexpensive raw materials for producing the suspension in the method for producing the suspension described in the sixth paragraph.
When a thermosetting resin molding material is used, the softening point of the molding material is lower than the thermal decomposition temperature of the inorganic metal compound complex. Therefore, when producing the second suspension, on the surface of the softened pellets or powders, a group of metal nanoparticles are simultaneously precipitated by thermal decomposition of the complex, and the pellets or powders are A second suspension is produced in which the mass is dispersed in the organic compound.
When using a molding material made of an amorphous thermoplastic resin, a molding material having a glass transition temperature lower than the thermal decomposition temperature of the complex of the inorganic metal compound is used. Therefore, when the second suspension is produced, a group of metal nanoparticles are simultaneously precipitated on the surface of the softened pellet by the thermal decomposition of the complex, and the group of the pellets is dispersed in the organic compound. Two suspensions are produced.
Further, when using a molding material made of a crystalline thermoplastic resin, a molding material having a melting point lower than the thermal decomposition temperature of the complex of the inorganic metal compound is used. Therefore, when the second suspension is produced, on the surface of the melted pellets, a group of metal nanoparticles are simultaneously precipitated by the thermal decomposition of the complex, and the group of the pellets is dispersed in the organic compound. Two suspensions are produced.
As described above, according to the production method of the present suspension, a complex consisting of an inorganic metal compound which is an inexpensive industrial chemical, methanol which is the most general-purpose alcohol, and a general-purpose industrial chemical. Is used as a raw material, a synthetic resin molding material of various materials is used to produce a first suspension, and the first suspension is further subjected to a reducing atmosphere at 180 to 220° C. A large amount of the suspension described in the sixth paragraph can be produced at a low cost only by heat treatment at the temperature of.

In the method of manufacturing the suspension described above, the metal compound mentioned above is a first feature of the oxygen ions constituting the carboxyl group of a carboxylic acid is covalently bonded to the metal ion, the said carboxylic acid consists of saturated fatty acids A carboxylic acid metal compound having two characteristics, wherein the alcohol is methanol, and the organic compound is an aromatic carboxylic acid ester, glycols, glycol ethers or any one of glycerin. An organic compound, the carboxylic acid metal compound is used as the metal compound, methanol is used as the alcohol, and the one kind of organic compound is used as the organic compound, according to the production method for producing the suspension described above. A method for producing the suspension, which comprises producing a suspension.

That is, the carboxylic acid metal compound having the two characteristics in the method for producing the present suspension undergoes thermal decomposition at 290 to 430° C. in the air atmosphere to deposit a metal. Further, it is dispersed at a concentration close to 10% by weight in methanol, which is the most general-purpose alcohol. Therefore, the carboxylic acid metal compound serves as a raw material for producing a suspension in the method for producing a suspension described in the sixth paragraph.
That is, in the carboxylic acid metal compound having both the first characteristic that the oxygen ion constituting the carboxyl group of the carboxylic acid is covalently bonded to the metal ion and the second characteristic that the carboxylic acid is a saturated fatty acid, the metal ion is This is the largest ion, and the distance between the oxygen ion that constitutes the carboxyl group and the metal ion is longer than the distance between other ions. When a carboxylic acid metal compound having such a characteristic in molecular structure is heat-treated in an air atmosphere, when the boiling point of the carboxylic acid is exceeded, the bond between the oxygen ion and the metal ion forming the carboxyl group is first broken, and the carboxylic acid Separates into metal. Furthermore, when the carboxylic acid is composed of a saturated fatty acid, it does not have an unsaturated structure in which carbon atoms are excessive with respect to hydrogen atoms, so that the carboxylic acid has a heat of vaporization depending on the molecular weight and the number of the carboxylic acid. It is vaporized and vaporized, and when vaporization is completed, metal is deposited. Examples of such carboxylic acid metal compounds include octyl acid metal compounds, lauric acid metal compounds, and stearic acid metal compounds. The boiling point of octylic acid is 228°C, the boiling point of lauric acid is 296°C, and the boiling point of stearic acid is 361°C. Therefore, thermal decomposition of these carboxylic acid metal compounds is completed in the air atmosphere at 290 to 430°C. Further, it is dispersed in methanol at a ratio close to 10% by weight.
Further, the carboxylic acid metal compound is an inexpensive industrial chemical that can be easily synthesized. That is, a carboxylic acid, which is the most versatile organic acid, is reacted with a strong alkali to produce a carboxylic acid alkali metal compound, and a carboxylic acid alkali metal compound is reacted with an inorganic metal compound to synthesize a carboxylic acid metal compound. It Therefore, it is the cheapest organometallic compound among organometallic compounds. Therefore, the heat treatment temperature is higher than that of the complex composed of the inorganic metal compound described in the ninth paragraph, but the metal compound is cheaper than the complex.
In addition, the aromatic carboxylic acid esters, glycols, glycol ethers or glycerin used in the method for producing the present suspension have the first property of being dissolved or miscible in methanol and the viscosity of which is 20 times or more higher than that of methanol. There is an organic compound having both the second property, the third property having a melting point lower than 20° C., and the fourth property having a boiling point higher than the thermal decomposition temperature of the carboxylic acid metal compound. Such organic compounds are general-purpose industrial chemicals. Therefore, such an organic compound is an inexpensive raw material for producing a suspension in the method for producing a suspension described in the sixth paragraph.
Therefore, when any one of the above-mentioned organic compounds is mixed with the methanol dispersion of the carboxylic acid metal compound, the carboxylic acid metal compound and the organic compound are uniformly mixed in a molecular state. When a mixture of synthetic resin molding materials is mixed with this mixed solution to form a mixture, the viscosity of the organic compound is 20 times or more higher than the viscosity of methanol, so that the mixed solution has a thickness corresponding to the viscosity of the mixed solution. Adhere to. When methanol is vaporized from this mixture, the carboxylic acid metal compound disperses in methanol but does not disperse in the organic compound, so that fine crystals of the carboxylic acid metal compound are simultaneously precipitated on the surface of the molding material. As a result, a cluster of fine crystals of the metal carboxylate compound is deposited on the surface of the molding material, and a cluster of the molding material is dispersed in a liquid organic compound to produce a first suspension. Furthermore, when the first suspension is heat-treated to thermally decompose the carboxylic acid metal compound, granular metal nanoparticles having a size of 40-60 nm corresponding to the size of fine crystals of the carboxylic acid metal compound are produced. , All at once on the surface of the molding material. Since the metal nanoparticles are deposited in an active state with no impurities, the adjacent metal nanoparticles are metal-bonded to each other at the contacting site, and a collection of metal-bonded metal nanoparticles is deposited on the surface of the molding material. A second suspension is produced in which this mass of molding material is dispersed in a liquid organic compound. Therefore, the carboxylic acid metal compound, methanol, and the organic compound in the method for producing the suspension are second inexpensive raw materials for producing the suspension in the method for producing the suspension described in the sixth paragraph.
When a molding material composed of an amorphous thermoplastic resin is used, the glass transition temperature is higher than the thermal decomposition temperature of the complex composed of the inorganic metal compound, and lower than the thermal decomposition temperature of the metal octylate compound. To use. At this time, a metal octylate compound is used as a raw material for the metal nanoparticles. Therefore, when producing the second suspension, a group of metal nanoparticles by thermal decomposition of the metal octylate compound is simultaneously precipitated on the softened pellet surface, and a group of such pellets dispersed in the organic compound. A second suspension is produced.
When a molding material made of a crystalline thermoplastic resin is used, a molding material having a melting point higher than the thermal decomposition temperature of the complex composed of an inorganic metal compound and lower than the thermal decomposition temperature of the metal octylate compound is used. At this time, a metal octylate compound is used as a raw material for the metal nanoparticles. Therefore, when producing the second suspension, on the surface of the melted pellets, the thermal decomposition of the metal octylate compound causes a simultaneous precipitation of a collection of metal nanoparticles, and the collection of such pellets is an organic compound. A second suspension dispersed in is prepared.
Furthermore, when a molding material made of a crystalline thermoplastic resin having a melting point higher than the thermal decomposition temperature of the metal octylate compound is used, the metal laurate compound is used as a raw material for the metal nanoparticles. Therefore, during the production of the second suspension, on the surface of the molten pellets, the thermal decomposition of the metal laurate compound causes simultaneous precipitation of a collection of metal nanoparticles, and these collections of pellets form an organic compound. A second dispersed suspension is produced.
As described above, according to the method for producing the present suspension, a metal carboxylate compound that is an inexpensive industrial chemical, methanol of a general-purpose alcohol, and an organic compound that is a general-purpose industrial chemical. Are used as raw materials, and further, a first suspension is manufactured using molding materials of various synthetic resins, and the first suspension is heat-treated at a temperature of 290 to 430° C. in an air atmosphere. By doing so, the suspension described in the sixth paragraph can be produced in large quantities at low cost.

A manufacturing method for manufacturing a molded body by a compression molding method using a suspension manufactured according to the above-mentioned manufacturing method is a method for preparing a cavity for filling the suspension manufactured according to the above-mentioned manufacturing method with the suspension in advance. The temperature of the molding machine that raises the boiling point of the organic compound to be compressed and compresses the suspension is raised in advance to a temperature higher than that of the cavity, and then the cavity is filled with the suspension to suspend the suspension. The organic compound is vaporized from the liquid, and further, the molding machine is lowered into the cavity, and the suspension machine filled in the cavity is heated by the molding machine, and a gradually increasing pressure is applied. , vaporizing the organic compound remaining in the suspension, further, the suspension molding material forming by thermally melting or thermal softening, and after this, to compressive deformation of the molding material, after which the molding machine temporarily stops the pressurization by so get out the air of the organic compounds remaining from the cavity and forming machine, further, by the molding machine again, heated the suspension filled in the cavity as well as, adding the pressure is greater than pressure, whereby the molding material to compressive deformation, with covered a collection of nanoparticles of metals and metal binding, nano particles of the said metal adjacent to the metal binding Thus, the compression-deformed molding materials are bonded to each other, and a molded body is manufactured in a gap formed by the cavity and the molding machine. A compression molding method using a suspension manufactured according to the manufacturing method described above. A manufacturing method for manufacturing a molded article according to.

In other words, according to the method for producing the molded article, the suspension produced by the above-described production method is used, and the method is similar to the conventional compression molding method. A synthetic resin molded body having the property not to be produced is manufactured in the gap formed by the cavity and the molding machine.
That is, the cavity is heated in advance to the boiling point of the organic compound forming the second suspension described in the sixth paragraph. Further, the temperature of the molding machine is raised in advance to a temperature higher than that of the cavity. The second suspension has both slipperiness and stickiness due to the presence of the organic compound. Therefore, the cavity is easily filled with the second suspension, and thereafter, most of the organic compound is vaporized from the second suspension. On the other hand, since the residual organic compound has a high viscosity, the organic compound does not separate from the molding material, which causes the molding material to have slipperiness and facilitates the movement of the molding material. The vaporized organic compound is reused by installing a recovery machine near the cavity and aspirating with the recovery machine. Then, the molding machine is lowered into the cavity, the second suspension is heated by the molding machine, and a gradually increasing pressure is applied. At this time, the remaining organic compounds are first vaporized from the second suspension, and the second suspension becomes a set of molding material covered with a set of metal-bonded metal nanoparticles. Next, the molding material is melted or softened by heat, and the molding material is compressed and deformed by the gradually increasing pressure. On the other hand, the gas of the organic compound is not limited to the group of molding materials due to the gradually increasing pressure, and is discharged to the gap between the group of molding materials and the cavity and the gap between the group of molding materials and the molding machine. Thereafter, the pressurization by the molding machine is once stopped, the gas of the organic compound is allowed to escape from the cavity and the molding machine, and the escaped gas is sucked by the recovery machine and reused. Therefore, no gas exists in the collection of molding material in the cavity, and no vacuole is formed inside the molding. After that, a pressing force larger than the above-mentioned pressing force is applied to the cluster of molding materials by the molding machine to further compress and deform the molding materials while raising the temperature. As a result, the compression-deformed molding material is covered with a collection of metal-bonded metal nanoparticles. Further, since the molding material is heated to a temperature higher than the temperature at which the metal nanoparticles are deposited, the metal-bonded metal nanoparticles are activated and slightly coarsened, and the metal nanoparticles slightly coarsened. Will be metal-bonded again. For this reason, the collection of metal nanoparticles covering the molding material is re-metal-bonded with each other, so that the compression-deformed molding materials are bonded to each other, and a molded body composed of the collection of molding materials is formed by the cavity and the molding machine. Is formed in the gap. Since the group of metal-bonded metal nanoparticles covers the molding material by forming a laminated structure in which metal nanoparticles are stacked, the group of metal-bonded metal nanoparticles has a certain bonding strength. , Forming an airtight coating to cover the molding material. Therefore, the molded body has no voids inside, is nonflammable, and has the property of not self-igniting. Further, since the molded body has properties close to those of metal, for example, a heat dissipation base material having excellent thermal conductivity can be manufactured by the compression molding method.
That is, since the temperature at which the metal compound is thermally decomposed and the metal nanoparticles are deposited is lower than the boiling point of the organic compound, the vaporization of the organic compound and the compression deformation of the heat-melted or heat-softened molding material are performed. , The collection of metal nanoparticles is continuously heated. Therefore, thermal energy is continuously supplied to the collection of metal nanoparticles, and the metal nanoparticles are activated again. On the other hand, the collection of metal nanoparticles that were shielded from the outside world by organic compounds does not change over time and has no impurities, so activated metal nanoparticles grow by incorporating adjacent metal nanoparticles. Then, the slightly coarsened metal nanoparticles are again metal-bonded to each other at the contact site, and again become a group of metal-bonded gold nanoparticles. The process in which the metal nanoparticles are heated and activated, the nanoparticles slightly grow, and the slightly grown nanoparticles re-metal bond is repeated in the cavity each time the molding material is heated. .. As a result, the compression-deformed molding material is covered with a collection of metal-bonded metal nanoparticles, and the collection of metal nanoparticles covering the molding material is metal-bonded to each other to bond the molding material to each other, forming a molded body. To be done. Therefore, all the molding materials constituting the molded body are covered with a film composed of a collection of metal-bonded metal nanoparticles having a certain bonding strength, and all the molding materials have an airtight coating that blocks the external atmosphere. Covered with. Therefore, the molded product has the property of being nonflammable and not self-igniting.
When a thermosetting resin is used as the molding material, when the second suspension is filled in the cavity heated to the boiling point of the organic compound, the organic compound is vaporized and the molding material is softened. The polymerization reaction begins. Further, when the molding material is heated and pressurized by the molding machine, the remaining organic compound is first vaporized, and then the softened molding material is compressed and deformed. Thus, after the organic compound has vaporized, the molding material is covered with a collection of metal-bonded metal nanoparticles. Furthermore, a collection of metal nanoparticles smaller than the molding material by three digits or more deforms following the deformation of the molding material and continues to cover the compression-deformed molding material. Further, since the temperature is raised to a temperature higher than the temperature at which the metal nanoparticles are deposited, the metal-bonded metal nanoparticles grow and become slightly coarse, and the coarse metal nanoparticles re-metal bond. Therefore, a collection of metal-bonded metal nanoparticles covers the molding material in which the polymerization reaction has progressed, and a collection of metal nanoparticles covering the molding material forms a metal bond and the molding materials bond to each other, resulting in a thermosetting resin. A molded body made of is produced.
In addition, since the thermosetting resin undergoes a polymerization reaction as the temperature rises and a thermosetting also proceeds at the same time, an excessive pressure is required to compress the molding material that has undergone the thermosetting too much. On the other hand, the softening point of the thermosetting resin is lower than the temperature at which the complex composed of the inorganic metal compound is thermally decomposed. Therefore, the temperature of the molding machine that heats and compresses the second suspension is higher than the temperature at which the complex thermally decomposes, but approaches the thermal decomposition temperature of the complex depending on the softening point. As a result, the molding material in a softened state before the thermosetting progresses excessively is compressed, and the compressed molding material is further heated by the molding machine to cause the polymerization reaction to proceed. A molded body of thermosetting resin is manufactured.
Furthermore, when an amorphous thermoplastic resin is used as the molding material, the temperature of the molding machine is higher than the glass transition temperature of the amorphous resin and higher than the temperature at which the metal nanoparticles are deposited, but the glass transition temperature Depending on the temperature of the metal nanoparticles. Thus, when heat and pressure are simultaneously applied to the second suspension by the molding machine, the organic compound is first vaporized, and then the softened pellet is compressed and deformed before the viscosity of the pellet is reduced. Thus, after the organic compound has vaporized, the pellet is continuously covered with a collection of metal-bonded metal nanoparticles. Furthermore, a group of metal nanoparticles, which is smaller than the pellet by five orders of magnitude, deforms following the deformation of the pellet and continues to cover the deformed pellet. Further, since the temperature is raised to a temperature higher than the temperature at which the metal nanoparticles are deposited, the metal-bonded metal nanoparticles grow and become slightly coarse, and the coarse metal nanoparticles re-metal bond. As a result, the pellets are again covered with a group of metal nanoparticles that are metal-bonded, and the group of metal nanoparticles that cover the pellet are metal-bonded again and the pellets are bonded to each other, forming from an amorphous thermoplastic resin. The body is manufactured.
When a crystalline thermoplastic resin is used as the molding material, the temperature of the molding machine is higher than the melting point of the crystalline resin and higher than the temperature at which the metal nanoparticles are deposited, but the temperature of the metal Close to the temperature at which the particles precipitated. Thus, when heat and pressure are simultaneously applied to the second suspension by the molding machine, the organic compound is first vaporized, and thereafter, the melted pellets are compression-deformed before the viscosity of the pellets is reduced. Thus, after the organic compound has vaporized, the pellet is continuously covered with a collection of metal-bonded metal nanoparticles. Furthermore, a group of metal nanoparticles, which is smaller than the pellet by five orders of magnitude, deforms following the deformation of the pellet and continues to cover the deformed pellet. Further, since the temperature is raised to a temperature higher than the temperature at which the metal nanoparticles are deposited, the metal-bonded metal nanoparticles grow and become slightly coarse, and the coarse metal nanoparticles re-metal bond. As a result, the pellet is again covered with a group of metal nanoparticles that are metal-bonded, and the group of metal nanoparticles that cover the pellet is again metal-bonded and the molding material is bonded to each other, forming a crystalline thermoplastic resin. The body is manufactured.
After that, the molding machine is pulled up and the molded body is taken out from the cavity, so that a molded body composed of a collection of solidified molding materials is obtained. This solidified molding material is covered with a collection of metal-bonded metal nanoparticles and is shielded from the atmosphere. Therefore, the molded body to which the solidified molding material is bonded has no voids inside, is incombustible, and has the property of not self-igniting.
Since the molded body has no vacuoles inside, even if the temperature is raised to a high temperature during a fire, the volume expansion of the vacuoles does not occur, and the collection of metal-bonded metal nanoparticles is not destroyed. Moreover, even if the temperature of the molded body is raised to a high temperature, since the size of the metal nanoparticles is smaller than three digits, the volume expansion of the synthetic resin causes the collection of metal-bonded metal nanoparticles to deform. , A collection of metal-bonded metal nanoparticles is not destroyed. Therefore, nonflammability and the property of not self-igniting are maintained.
Furthermore, when recycling the molded body, the melting point of the metal constituting the metal nanoparticles, the melting point of the thermoplastic resin, or the reaction temperature of the thermosetting resin is largely different, and the specific gravity of the metal and the synthetic resin Therefore, it is easy to separate the metal nanoparticles from the compact during recycling, and the synthetic resin and the metal of the nanoparticles can be reused.
As described above, according to the method for producing the molded body, the four problems 2 to 5 described in the paragraph 5 are solved, and the compression molding method does not cause voids inside and is nonflammable. A synthetic resin molded body having a property of not having a self-ignition property is produced.

A manufacturing method for manufacturing a molded body by a transfer molding method using the suspension manufactured by the above-described manufacturing method is a method of preparing a pot for filling the suspension manufactured by the above-described manufacturing method with the suspension in advance. The temperature is raised to the boiling point of the organic compound constituting the cavity, and the cavity into which the suspension is pushed is preheated to a temperature higher than the pot, the pot is filled with the suspension, and the compound is vaporized, after this, by installing a plunger in the pot is pressurized while heating the suspension filled in the pot, vaporizing the organic compound remaining in the suspension, Further, the molding material forming the suspension is heat-melted or softened, and then the molding material is pushed into the cavity. Thereafter, the pressurization by the plunger is once stopped, and the remaining A gas of an organic compound is allowed to escape from the cavity, and the suspension is pushed into the cavity again by the plunger, and a gradually increasing pressurizing force is applied, thereby compressing and deforming. the molding materials, together with covered a collection of nanoparticles of metals and metal bonded, by nano particles of the said metal adjacent to metal bonding, molding materials with each other and the compression deformation is coupled, in the cavity A manufacturing method for manufacturing a molded body by a transfer molding method using a suspension manufactured according to the above-described manufacturing method, wherein a molded body is manufactured.

Further, the temperature of the cavity is raised in advance to a temperature higher than that of the pot. The second suspension has both slipperiness and stickiness due to the presence of the organic compound. Therefore, the pot is easily filled with the second suspension, and thereafter, most of the organic compounds are vaporized from the second suspension. On the other hand, since the residual organic compound has a high viscosity, the organic compound does not separate from the molding material, which causes the molding material to have slipperiness and facilitates the movement of the molding material. The vaporized organic compound is reused by installing a recovery machine near the pot and sucking it with the recovery machine. After that, the second suspension filled in the pot is pressurized with a plunger, passed through a spool, a lunch, and a gate, and then pushed into the cavity. The temperature of the second suspension pushed into the cavity is raised, and a constant pressure is applied. At this time, the remaining organic compounds are first vaporized, and the second suspension becomes a set of molding materials covered with a set of metal-bonded metal nanoparticles. Furthermore, the molding material melts or softens, and is compressed and deformed by the applied pressure. Note that the vaporized organic compound is not retained inside the group of molding materials by a pressing force, and is discharged into the gap between the group of molding materials and the cavity and the gap between the group of molding materials and the plunger. After that, the pressurization of the plunger is once stopped, the gas is allowed to escape from the cavity, and the gas is sucked by the recovery machine for reuse. Therefore, no gas exists in the collection of molding material in the cavity, and no vacuole is formed inside the molding. Then, the plunger re-compresses the mass of the molding material pushed into the cavity through the spool, the launcher, and the gate with a gradually increasing pressure while heating. As a result, the molding material covered with the collection of metal-bonded metal nanoparticles is further deformed. Further, since the molding material is heated to a temperature higher than the temperature at which the metal nanoparticles are deposited, the metal-bonded metal nanoparticles are activated and slightly coarsened, and the metal nanoparticles slightly coarsened.

Therefore, the collection of the metal nanoparticles covering the molding material is again metal-bonded, so that the deformed molding materials are bonded to each other, and the molded body is formed in the cavity. Since the collection of metal-bonded metal nanoparticles forms a laminated structure in which metal nanoparticles are stacked to cover the molding material, the collection of metal-bonded metal nanoparticles has a certain bonding strength. Also, an airtight film is formed to cover the molding material. Therefore, the molded body has no voids inside, is nonflammable, and has the property of not self-igniting. Further, since the molded body has a property close to that of metal, for example, a heat dissipation substrate having excellent thermal conductivity can be manufactured by the transfer molding method.
Further, as described in the 13th paragraph, since the temperature at which the metal compound is thermally decomposed and the metal nanoparticles are deposited is lower than the boiling point of the organic compound, when the organic compound is vaporized and when the organic compound is melted or softened by molding. As the material undergoes compressive deformation, the collection of metallic nanoparticles continues to heat up. Therefore, the process in which the metal nanoparticles are heated and activated, the nanoparticles slightly grow, and the slightly grown nanoparticles re-metal bond with each other in the pot every time the molding material is heated. Repeat in the cavity. As a result, the compression-deformed molding material is covered with a collection of metal-bonded metal nanoparticles, the collection of metal nanoparticles covering the molding material are metal-bonded to each other, and the molding materials are bonded to each other.

In addition, since the molding material that has been compressed and deformed in the cavity is a softened solid pellet or powder, a collection of metal nanoparticles that are three or more orders of magnitude smaller than the molding material deforms following the deformation of the molding material. Then, the molding material continues to be covered with a collection of metal nanoparticles that are metal-bonded.

It is higher than the temperature and higher than the temperature at which the metal nanoparticles are deposited, but approaches the temperature at which the metal nanoparticles are deposited according to the glass transition temperature. Further, a group of metal nanoparticles smaller by 5 digits than the softened pellet deforms following the deformation of the pellet, and the group of metal nanoparticles in which the compression-deformed pellet is metal-bonded continues to be covered. As a result, the molding material is bonded through the metal bond of the metal nanoparticles, and the molded body made of the amorphous thermoplastic resin is manufactured.
Furthermore, when a molding material made of a crystalline thermoplastic resin is used, the temperature of the cavity for heating and compressing the second suspension is higher than the melting point of the pellet, as described in paragraph 13, and Although it is higher than the temperature at which the metal nanoparticles are deposited, it is brought close to the temperature at which the metal nanoparticles are deposited depending on the melting point. In addition, a group of metal nanoparticles that is smaller than the heat-melted pellet by five orders of magnitude deforms following the deformation of the pellet, and the group of metal nanoparticles in which the deformed pellet is metal-bonded continues to be covered. As a result, the molding material is bonded through the metal bond of the collection of metal nanoparticles, and the molded body made of the crystalline thermoplastic resin is manufactured.
After that, the plunger is pulled up, and the molded body is taken out from the cavity, so that a molded body made of a collection of solidified molding materials is obtained. The solidified molding material is covered with a collection of metal-bonded metal nanoparticles, and has an airtight property that shuts off the atmosphere from the outside. Therefore, the molded body to which the solidified molding material is bonded has no voids inside, is incombustible, and has the property of not self-igniting.
Since the molded body has no vacuoles inside, even if the temperature is raised to a high temperature during a fire, the volume expansion of the vacuoles does not occur, and the collection of metal-bonded metal nanoparticles is not destroyed. Moreover, even if the temperature of the molded body is raised to a high temperature, since the size of the metal nanoparticles is smaller than three digits, the volume expansion of the synthetic resin causes the collection of metal-bonded metal nanoparticles to deform. , A collection of metal-bonded metal nanoparticles is not destroyed. Therefore, nonflammability and the property of not self-igniting are maintained.
Furthermore, when recycling the molded body, the melting point of the metal constituting the metal nanoparticles, the melting point of the thermoplastic resin, or the reaction temperature of the thermosetting resin is largely different, and the specific gravity of the metal and the synthetic resin Therefore, it is easy to separate the metal nanoparticles from the compact during recycling, and the synthetic resin and the metal of the nanoparticles can be reused.

Also, an airtight film is formed to cover the molding material. Therefore, the molded body has no voids inside, is nonflammable, and has the property of not self-igniting. Further, since the molded body has a property close to that of metal, for example, a heat dissipation base material having excellent thermal conductivity can be manufactured by the injection molding method.
Further, as described in the 13th paragraph, since the temperature at which the metal compound is thermally decomposed and the metal nanoparticles are deposited is lower than the boiling point of the organic compound, when the organic compound is vaporized and when the organic compound is melted or softened by molding. As the material undergoes compressive deformation, the collection of metallic nanoparticles continues to heat up. Therefore, the process in which the metal nanoparticles are heated and activated, the nanoparticles slightly grow, and the slightly grown nanoparticles re-metal bond with each other in the cylinder every time the molding material is heated.

The organic compound is vaporized from the suspension, and thereafter, the suspension filled in the cylinder is pressurized by a screw installed in the cylinder, and the suspension is fed through a groove inside the die. The suspension is extruded through the outlet of the groove, whereby the remaining gas of the organic compound is vaporized from the outlet of the die, and the molding material forming the suspension is melted or melted by heat. softened, and thereafter, molding material is compressed and deformed, the molding material was compression deformation, with covered a collection of nanoparticles of metals and metal bonded, by nano particles of the said metal adjacent to the metal binding An extrusion molding method using the suspension manufactured by the manufacturing method described above, in which the compression-deformed molding materials are bonded to each other, and the molded body in which the molding materials are bonded to each other is extruded from the exit of the groove of the die.

That is, the cylinder is preheated to the boiling point of the organic compound forming the second suspension described in the sixth paragraph. Further, the die installed in front of the cylinder is preheated to a temperature higher than that of the cylinder. The second suspension has both slipperiness and stickiness due to the presence of the organic compound. As a result, the cylinder is easily filled with the second suspension, after which many of the organic compounds are vaporized from the second suspension. On the other hand, since the residual organic compound has a high viscosity, the organic compound does not separate from the molding material, which causes the molding material to have slipperiness and facilitates the movement of the molding material. In addition, the vaporized organic compound is sucked and reused by a recovery machine arranged outside the cylinder. After this, the second suspension is pressurized by the rotational movement of the screw installed in the cylinder, and the groove with a narrow volume is formed inside the die with a predetermined length installed in front of the cylinder. , Passing the pressurized second suspension. As a result, the second suspension passes through the groove having the predetermined length and the narrow cross-sectional area, so that the pressing force is continuously applied to the second suspension and the second suspension is applied. The suspension liquid is gradually heated. At this time, the remaining organic compounds are first vaporized, and the second suspension becomes a set of molding materials covered with a set of metal-bonded metal nanoparticles.

Note that the vaporized organic compound is continuously subjected to a pressure and is not limited to the group of molding materials, but is discharged from the group of molding materials, discharged from the outlet of the die, and collected by the collecting machine. Therefore, there is no gas in the cluster of molding material, and no vacuole is formed inside the molded body. Further, since the temperature of the molding material is raised to a temperature higher than the temperature at which the metal nanoparticles are deposited, the slightly coarsened metal nanoparticles are metal-bonded again. Therefore, the metal nanoparticles that have covered the molding material are re-metal-bonded to each other, so that the compression-molded molding materials are bonded to each other, and the molded body such as a sheet, tube, or pipe having the cross-sectional shape of the die groove As it is pushed out of the groove exit.

As a result, the compression-deformed molding material is covered with a collection of metal-bonded metal nanoparticles, and the collection of metal nanoparticles covering the molding material is metal-bonded and the molding materials are bonded to each other to form a collection of molding materials. A molded body made of is formed. Therefore, all the molding materials constituting the molded body are covered with a film composed of a collection of metal-bonded metal nanoparticles having a certain bonding strength, and all the molding materials have an airtightness that shuts off the atmosphere of the outside world. Covered with a film. As a result, the molded article has the property of being nonflammable and not self-igniting.
The pressure applied when the molding material passes through the inside of the die is smaller than that of other molding methods because the die outlet is open. Therefore, when a molding material made of an amorphous thermoplastic resin is used, the temperature of the die for heating and compressing the second suspension is sufficiently higher than the glass transition temperature. As a result, the softened pellets are easily compressed and deformed. Since the softened pellets are solid, they have high viscosity, and after the organic compound is vaporized, they are continuously covered with a collection of metal-bonded metal nanoparticles. In addition, a group of metal nanoparticles smaller by 5 digits than the pellet deforms following the deformation of the pellet, and the group of metal nanoparticles in which the deformed pellet is metal-bonded continues to be covered. As a result, the deformed pellets are bonded to each other by the metal bonding of the metal nanoparticles, and the amorphous thermoplastic resin molded body is extruded from the die exit.
Furthermore, when a molding material made of a crystalline thermoplastic resin is used, the temperature of the die for heating and compressing the second suspension is set higher than the melting point of the crystalline resin. Note that the melted pellet has high viscosity, and after the organic compound is vaporized, the pellet is continuously covered with a collection of metal-bonded metal nanoparticles. In addition, a group of metal nanoparticles that is smaller than the melted pellet by five orders of magnitude deforms following the deformation of the melted pellet, and the group of metal nanoparticles that are metal-bonded to the deformed pellet continues to be covered. As a result, the deformed pellets are bonded by the metal bond of the metal nanoparticles, and the molded body made of the crystalline thermoplastic resin is extruded from the exit of the die.
After that, the molded body is taken up by a take-up machine and wound by a roller to obtain a molded body composed of a collection of solidified molding materials. The solidified molding material is covered with a collection of metal-bonded metal nanoparticles, and has an airtightness that shields the atmosphere from the outside. Therefore, the molded body to which the solidified molding material is bonded has no voids inside, is incombustible, and has the property of not self-igniting.
Since the molded body has no vacuoles inside, even if the temperature is raised to a high temperature during a fire, the volume expansion of the vacuoles does not occur, and the collection of metal-bonded metal nanoparticles is not destroyed. Moreover, even if the temperature of the molded body is raised to a high temperature, since the size of the metal nanoparticles is smaller than three digits, the volume expansion of the synthetic resin causes the collection of metal-bonded metal nanoparticles to deform. , A collection of metal-bonded metal nanoparticles is not destroyed. Therefore, nonflammability and the property of not self-igniting are maintained.
Furthermore, when recycling the molded body, the melting point of the metal constituting the metal nanoparticles, the melting point of the thermoplastic resin, or the reaction temperature of the thermosetting resin is largely different, and the specific gravity of the metal and the synthetic resin Therefore, it is easy to separate the metal nanoparticles from the compact during recycling, and the synthetic resin and the metal of the nanoparticles can be reused.
As described above, according to the manufacturing method of the molded body, the four problems of the second to fifth described in the paragraph 5 are solved, and by the extrusion molding method, there is no void inside. A molded product of synthetic resin having nonflammability and non-self-ignition properties is manufactured.

A manufacturing method for manufacturing a molded body by an air blow molding method using the suspension manufactured by the above-mentioned manufacturing method is a method in which the cylinder filled with the suspension manufactured by the manufacturing method according to claim 1 is previously The temperature is raised to the boiling point of the organic compound forming the suspension, and a pair of molds sandwiching the suspension extruded in a tube shape is preheated to a temperature higher than the cylinder, and the suspension is carried out in the cylinder. A liquid is filled and the organic compound is vaporized from the suspension, and thereafter, the suspension filled in the cylinder is pressurized by a screw installed in the cylinder, and the suspension is charged. It passes through a groove inside a die installed in front of the cylinder, is extruded as the tube-shaped suspension from the outlet of the groove, and the tube-shaped suspension is sandwiched between the pair of molds, After closing the mold, the compressed air whose air pressure gradually increases is supplied to the inside of the tube-shaped suspension by an air blow device, and the tube-shaped suspension is inflated in the pair of molds. that, thereby, the gas of the organic compound remaining vaporized from the tube, further, the molding material constituting the suspension is heat-melted or heat softened, after which the molding material is compressed and deformed, forming shape materials the compressive deformation, with covered a collection of nanoparticles of metals and metal bonded, by nano particles of the said metal adjacent to metal bonding, molding materials with each other and the compressive deformation are combined, the A molded body in which the molding materials are bonded to each other is manufactured as a hollow molded body in the pair of molds, and a molded body is manufactured by an air blow molding method using the suspension manufactured by the manufacturing method described above. Manufacturing method to manufacture.

According to the method for producing the present molded body, the suspension produced by the above-mentioned production method is used, and in a method similar to the method for producing a hollow molded body by the conventional air blow molding method, voids are formed inside. In addition, a hollow molded body having a nonflammable property and a non-self-igniting property is manufactured in the mold.
That is, the cylinder is preheated to the boiling point of the organic compound forming the second suspension described in paragraph 6. The pair of molds is preheated to a temperature higher than that of the cylinder. The second suspension has both slipperiness and stickiness due to the presence of the organic compound. As a result, the cylinder is easily filled with the second suspension, after which many of the organic compounds are vaporized from the second suspension. On the other hand, since the residual organic compound has a high viscosity, the organic compound does not separate from the molding material, which causes the molding material to have slipperiness and facilitates the movement of the molding material. In addition, the vaporized organic compound is sucked and reused by a recovery machine arranged outside the cylinder. Then, the second suspension is pressurized by the rotational movement of the screw installed in the cylinder, and is extruded into a tube shape through a groove formed inside the die installed in front of the cylinder. Next, the second suspension extruded into a tube shape is sandwiched by a pair of molds. After that, the mold is closed, compressed air whose air pressure gradually increases is inflated to the inside of the tube sandwiched between the molds, the tube is inflated, and the tube is brought into close contact with the inside of the mold to form a hollow molded body. Form. At this time, the temperature of the tube is increased as the tube is brought into close contact with the mold, and the compressive stress to be brought into close contact with the mold is increased. Therefore, the remaining organic compound is first vaporized, and the vaporized organic compound is not retained in the tube due to the increasing compressive stress and is exhaled from the tube. Therefore, there is no gas inside the tube, and no vacuole is formed inside the hollow molded body. Thus, the second suspension becomes a mass of molding material covered with a mass of metal-bonded metal nanoparticles. Next, the molding material melts or softens, and is further compressed and deformed. Further, the temperature of the molding material is raised to a temperature higher than the temperature at which the metal nanoparticles are deposited, and the slightly coarsened metal nanoparticles are again metal-bonded. As a result, the molding materials are bonded to each other by the group of metal nanoparticles that are metal-bonded again, and a hollow molded body composed of the group of molding materials is formed in the mold. Since the collection of metal-bonded metal nanoparticles forms a laminated structure in which metal nanoparticles are stacked to cover the molding material, the collection of metal-bonded metal nanoparticles has a certain bonding strength. Also, an airtight film is formed to cover the molding material. Therefore, the hollow molded body has no voids inside, is nonflammable, and has the property of not self-igniting. Further, since the hollow molded body has a property close to that of a metal, the hollow molded body has excellent electrical conductivity and thermal conductivity.
Further, as described in the 13th paragraph, since the temperature at which the metal compound is thermally decomposed and the metal nanoparticles are deposited is lower than the boiling point of the organic compound, when the organic compound is vaporized and when the organic compound is melted or softened by molding. As the material undergoes compressive deformation, the collection of metallic nanoparticles continues to heat up. Therefore, the process in which the metal nanoparticles are heated and activated, the nanoparticles slightly grow, and the slightly grown nanoparticles re-metal bond with each other in the cylinder every time the molding material is heated. Repeat in the mold. As a result, the compression-deformed molding material is covered with a collection of metal-bonded metal nanoparticles, and the collection of metal nanoparticles covering the molding material is metal-bonded and the molding materials are bonded to each other to form a collection of molding materials. A molded body made of is formed. Therefore, all the molding materials constituting the molded body are covered with a film composed of a collection of metal-bonded metal nanoparticles having a certain bonding strength, and all the molding materials have an airtightness that shuts off the atmosphere of the outside world. Covered with a film. As a result, the molded article has the property of being nonflammable and not self-igniting.
The pressure applied by the compressed air is smaller than the pressure applied by the other molding methods, as in the extrusion molding method described in the 19th paragraph. Therefore, when a molding material made of an amorphous thermoplastic resin is used, the temperature of the pair of molds is set sufficiently higher than the glass transition temperature. Since the softened pellets are solid, they are continuously covered with a collection of metal-bonded metal nanoparticles after the organic compound is vaporized. Further, a group of metal nanoparticles smaller than the softened pellet by five orders of magnitude deforms following the deformation of the pellet, and the group of metal nanoparticles in which the deformed pellet is metal-bonded continues to be covered. As a result, the deformed pellets are bonded by the metal bond of the metal nanoparticles, and the molded body made of the amorphous thermoplastic resin is manufactured in the mold.
Furthermore, when a molding material made of a crystalline thermoplastic resin is used, the temperature of the pair of molds is set to a temperature higher than the melting point of the crystalline resin. Note that the melted pellet has high viscosity, and after the organic compound is vaporized, the pellet is continuously covered with a collection of metal-bonded metal nanoparticles. In addition, a group of metal nanoparticles that is smaller than the melted pellet by five orders of magnitude deforms following the deformation of the melted pellet, and the group of metal nanoparticles that are metal-bonded to the deformed pellet continues to be covered. As a result, the deformed pellets are bonded by metal bonds of metal nanoparticles, and a hollow molded body made of a crystalline thermoplastic resin is manufactured in the mold.
After that, the mold is opened, the gas of the organic compound is first recovered, and then the hollow molded body is taken out from the mold to obtain a molded body composed of a collection of solidified molding materials. The solidified molding material is covered with a collection of metal-bonded metal nanoparticles, and has an airtightness that shields the atmosphere from the outside. Therefore, the hollow molded body has a property that it has no vacuoles inside, is nonflammable, and does not self-ignite.
Since the molded body has no vacuoles inside, even if the temperature is raised to a high temperature during a fire, the volume expansion of the vacuoles does not occur, and the collection of metal-bonded metal nanoparticles is not destroyed. Moreover, even if the temperature of the molded body is raised to a high temperature, since the size of the metal nanoparticles is smaller than three digits, the volume expansion of the synthetic resin causes the collection of metal-bonded metal nanoparticles to deform. , A collection of metal-bonded metal nanoparticles is not destroyed. Therefore, nonflammability and the property of not self-igniting are maintained.
Furthermore, when recycling the molded body, the melting point of the metal constituting the metal nanoparticles, the melting point of the thermoplastic resin, or the reaction temperature of the thermosetting resin is largely different, and the specific gravity of the metal and the synthetic resin Therefore, it is easy to separate the metal nanoparticles from the compact during recycling, and the synthetic resin and the metal of the nanoparticles can be reused.
As described above, according to the manufacturing method of the molded body, the four problems of the second to fifth described in paragraph 5 are solved, and by the air blow molding method, there are no voids inside. A hollow molded article of synthetic resin having nonflammability and non-self-ignition properties is manufactured.

Method of manufacturing a molded body depending on the thermoforming molding method using a suspension prepared above was production method, the cylinder filling suspension produced by the production method according to claim 1, in advance The temperature is raised to the boiling point of the organic compound forming the suspension, and the upper mold for compressing the suspension and the lower mold connected to the suction hose of the vacuum pump are heated to a temperature higher than that of the cylinder in advance. Warming, filling the cylinder with the suspension, and vaporizing the organic compound from the suspension, after which the suspension filled in the cylinder by a screw installed in the cylinder Is pressurized, the suspension is passed through a groove inside a die installed in front of the cylinder, and the sheet-shaped suspension is extruded from the outlet of the groove to obtain the sheet-shaped suspension. It is sandwiched between the upper mold and the lower mold, the vacuum pump is operated, the upper mold is lowered to the lower mold, and gradually increases by the upper mold. A pressing force is applied to the sheet-like suspension, and the sheet-like suspension is brought into close contact with the lower mold and compressed by the upper mold, whereby the residual organic compound is retained. The gas is vaporized from the molding material forming the suspension , and the molding material is heat-melted or heat-softened, and then the molding material is compression-deformed, and the compression-deformed molding material is metal-bonded. While being covered with a collection of the metal nanoparticles formed by the above , the adjacent metal nanoparticles are metal-bonded to each other, the compression-deformed molding materials are bonded to each other, and the molding material in which the molding materials are bonded to each other, A manufacturing method for manufacturing a molded body by a thermoforming molding method using a suspension manufactured by the manufacturing method described above, which is manufactured in a gap formed by an upper mold and the lower mold.

That is, according to the method for producing the present molded body, the suspension produced by the above-mentioned production method is used, and the method is similar to the conventional thermoforming molding method. A synthetic resin molded body having a non-ignition property is manufactured in a gap formed between the upper mold and the lower mold. Note that this characteristic means is a manufacturing method close to the compression molding method described in the fourth characteristic means, but since a collection of molding material is brought into close contact with the mold by a vacuum pump, it has a wall thickness larger than that of the molded body according to the compression molding method. Suitable for producing thin compacts.
That is, the cylinder is preheated to the boiling point of the organic compound forming the second suspension described in paragraph 6. Further, the temperature of the pair of molds is raised to a temperature higher than that of the cylinder. The second suspension has both slipperiness and stickiness due to the presence of the organic compound. As a result, the cylinder is easily filled with the second suspension, after which many of the organic compounds are vaporized from the second suspension. On the other hand, since the residual organic compound has a high viscosity, the organic compound does not separate from the molding material, which causes the molding material to have slipperiness and facilitates the movement of the molding material. The vaporized organic compound is reused by installing a recovery machine near the cylinder and aspirating with the recovery machine. After this, the second suspension is pressurized by the movement of the screw installed in the cylinder, passes through the groove formed inside the die installed in front of the cylinder, and is extruded into a sheet from the groove outlet. .. Next, the second suspension extruded in a sheet shape is moved and sandwiched by a pair of molds. After that, the vacuum pump is operated to bring the second suspension into close contact with the lower mold, and the upper mold is lowered to the lower mold, so that the pressure applied by the upper mold is gradually increased. Add to the second suspension. At this time, the remaining organic compound is first vaporized, and the vaporized organic compound is not stayed in the group of molding materials due to the increasing pressure, but is discharged from the group of molding materials. Therefore, there is no gas in the collection of molding materials, and no void is formed inside the molding. Also, the second suspension becomes a set of molding materials covered with a set of metal-bonded metal nanoparticles. Next, the molding material is melted or softened, and is further compressed and deformed. Further, the temperature of the molding material is raised to a temperature higher than the temperature at which the metal nanoparticles are deposited, and the slightly coarsened metal nanoparticles are again metal-bonded. As a result, the molding material is bonded by a collection of metal-bonded metal nanoparticles, and a molding is formed in the gap formed by the upper mold and the lower mold. Since the collection of metal-bonded metal nanoparticles forms a laminated structure in which metal nanoparticles are stacked to cover the molding material, the collection of metal-bonded metal nanoparticles has a certain bonding strength. Also, an airtight film is formed to cover the molding material. Therefore, the molded body has no voids inside, is nonflammable, and has a property of not self-igniting. Further, since the molded body has a property close to that of metal, for example, a shield base material that reflects electromagnetic waves, an antistatic base material that does not charge static electricity, and the like can be manufactured by the thermoforming molding method.
Further, as described in the 13th paragraph, since the temperature at which the metal compound is thermally decomposed and the metal nanoparticles are deposited is lower than the boiling point of the organic compound, when the organic compound is vaporized and when the organic compound is melted or softened by molding. As the material undergoes compressive deformation, the collection of metallic nanoparticles continues to heat up. Therefore, the process in which the metal nanoparticles are heated and activated, the nanoparticles slightly grow, and the slightly grown nanoparticles re-metal bond with each other in the cylinder every time the molding material is heated. Repeat in the mold. As a result, the compression-deformed molding material is covered with a collection of metal-bonded metal nanoparticles, and the collection of metal nanoparticles covering the molding material is metal-bonded and the molding materials are bonded to each other to form a collection of molding materials. A molded body made of is formed. Therefore, all the molding materials constituting the molded body are covered with a film composed of a collection of metal-bonded metal nanoparticles having a certain bonding strength, and all the molding materials have an airtightness that shuts off the atmosphere of the outside world. Covered with a film. As a result, the molded article has the property of being nonflammable and not self-igniting.
When a molding material made of a thermosetting resin is used, the temperature of the pair of molds for heating and compressing the second suspension is set to the softening point of the thermosetting resin, as described in paragraph 13. Higher and higher than the temperature at which the complex thermally decomposes, but approaches the thermal decomposition temperature of the complex depending on the softening point. Also, since the molding material that has been compressed and deformed by the mold is a solid pellet or powder, a collection of metal nanoparticles that are three or more digits smaller than the molding material deforms following the deformation of the molding material. , A collection of metal nanoparticles metal-bonded to the molding material continues to be covered. As a result, the molding material in which the polymerization reaction has proceeded is covered with a collection of metal-bonded metal nanoparticles, and the molding material is bonded through the metal bonds of the metal nanoparticles to produce a molded product made of a thermosetting resin. To be done.
When a molding material made of an amorphous thermoplastic resin is used, the temperature of the pair of molds for heating and compressing the second suspension is set to the amorphous resin as described in paragraph 13. Although the temperature is higher than the glass transition temperature of and is higher than the temperature at which the metal nanoparticles are deposited, the temperature is brought close to the temperature at which the metal nanoparticles are deposited according to the glass transition temperature. Further, a group of metal nanoparticles smaller than the softened pellet by five orders of magnitude deforms following the deformation of the pellet, and the group of metal nanoparticles in which the deformed pellet is metal-bonded continues to be covered. As a result, the deformed pellets are bonded by the metal bond of the metal nanoparticles, and a molded body made of the amorphous thermoplastic resin is manufactured.
Furthermore, when a molding material made of a crystalline thermoplastic resin is used, the temperature of the pair of molds for heating and compressing the second suspension is set to be higher than the melting point of the molding material, as described in paragraph 13.

Embodiment 1
An embodiment for producing a molded body having nonflammability and not self-ignition according to the present invention by using molding materials made of various synthetic resins will be described.
Synthetic resins are roughly classified into thermosetting resins and thermoplastic resins. The thermosetting resin is softened by heating, and when it is further heated, a polymerization reaction occurs and the viscosity decreases, while a polymer network structure is formed, the molecular weight increases and curing begins, and the polymer returns to the original polymer. Absent. Further, the higher the temperature is, the more the polymerization reaction proceeds, and the thermosetting progresses as the polymerization reaction progresses. Therefore, an excessive pressure is required to compress the pellets or powder particles that have undergone excessive heat curing. Therefore, in the production of a thermosetting resin molded body, a pellet or a collection of powder or granules is heated to be softened, and a pellet or a collection of powder or granules before being over-cured is directly bonded by pressing, and further heated. Then, the polymerization reaction of the combined pellets or powder is proceeded. As a result, a molded body composed of a collection of pellets or powders that have undergone the polymerization reaction is produced.
The object of the present invention is to produce a shaped body which is nonflammable and which does not self-ignite. Therefore, in order to achieve the object of the present invention, a collection of metal-bonded metal nanoparticles covers the molding material, and the molding materials are bonded to each other by metal bonding of the collection of metal nanoparticles covering the molding material. On the other hand, the softening point of the thermosetting resin pellet or powder is lower than the temperature at which the complex of the inorganic metal compound is thermally decomposed. For this reason, the temperature of the molding machine or the mold for heating and compressing the pellets or the aggregate of powder and granules is set to a temperature higher than the thermal decomposition temperature of the complex but close to the thermal decomposition temperature of the complex depending on the softening point. .. This allows the pellets or granules to be compressed before the thermosetting proceeds too much. Further, after the organic compound is vaporized, the molding material is continuously covered with a collection of metal-bonded metal nanoparticles. Furthermore, a collection of metal nanoparticles smaller than the pellets or particles by at least three digits is deformed following the compressive deformation of the pellets or particles, and the deformed pellets or particles are made of metal-bonded metal. A collection of nanoparticles keeps covering. Further, since the temperature of the collection of metal nanoparticles is raised to a temperature higher than the deposition temperature, the metal-bonded metal nanoparticles grow and become slightly coarse, and the slightly coarse metal nanoparticles become metal again. Join. Therefore, a collection of metal nanoparticles that are metal-bonded again covers the pellet or powder, and a collection of metal nanoparticles that covers the pellet or powder is remetal-bonded so that the pellets or powder are bound to each other. To do. This achieves the object of the present invention.
When the thermosetting resin exceeds the softening point, the molding material is softened, but the polymerization reaction gradually proceeds, and the molding material is cured according to the progress of the polymerization reaction. Therefore, unless the molding material is compressed with a predetermined amount of pressure, the pellets or powders that have undergone the polymerization reaction do not deform. On the other hand, the extrusion molding method and the air blow molding method are not suitable for producing a molded product using a thermosetting resin, because a large pressure cannot be applied to the softened pellet or powder.

On the other hand, the thermoplastic resin is softened when heated to be in a rubber-like elasticity state, and loses elasticity when heated further and approaches a fluid state (liquid phase). At this time, since the amorphous resin and the crystalline resin have large differences in crystallinity, the behavior during heating is different. An amorphous portion is mixed in the crystalline resin, and the volume ratio of the crystalline portion is called crystallinity. Similarly, in the amorphous resin, a crystalline portion is partially mixed, and the volume ratio of the amorphous portion is referred to as the amorphous degree.
In other words, when the temperature of the amorphous thermoplastic resin is raised, the brittle state in which the chains of the amorphous polymer are bound to the state in which the rubber-like elasticity is exhibited. This transition is called glass transition, and the temperature at which glass transition occurs is called glass transition temperature. Below this glass transition temperature, the main chain of the molecule is in a solidified state frozen into a glass, but above the glass transition temperature, the main chain of the molecule begins to rotate and vibrate, and the elastic modulus increases with increasing temperature. Decreases linearly. When the temperature is further raised, the rubber-like flow state approaches the liquid flow state in which elasticity has been lost, but since the crystallinity is low, the temperature at which all the polymers transition to the liquid state is not clear and has no melting point. Therefore, in the production of a molded product of an amorphous resin, the pellets are heated to a temperature exceeding the glass transition temperature, the softened pellets are pressed and deformed by compression, and the compression-deformed pellets are directly bonded and molded. Manufacture the body.
The object of the present invention is to produce a shaped body which is nonflammable and which does not self-ignite. Therefore, it is sufficient that the metal nanoparticles bonded to each other cover the pellets and the metal nanoparticles covering the pellets are bonded to each other by metal bonding. On the other hand, the temperature of a molding machine or a mold for heating and compressing a collection of pellets is higher than the boiling point of the organic compound and higher than the glass transition temperature of the pellets, but close to the glass transition temperature. This causes the pellet to compressively deform before the viscosity of the pellet decreases. In addition, after the organic compound is vaporized, the pellet is continuously covered with a collection of metal-bonded metal nanoparticles. Furthermore, a group of metal nanoparticles smaller by 5 digits than the pellet deforms following the deformation of the pellet, and the group of metal nanoparticles in which the compression-deformed pellet is metal-bonded continues to be covered. Further, the temperature of the collection of metal nanoparticles is raised to a temperature higher than the deposition temperature, the metal-bound metal nanoparticles grow and become slightly coarse, and the slightly coarse metal nanoparticles re-metal bond. .. Therefore, the group of metal nanoparticles that are metal-bonded again covers the pellet, and the group of metal nanoparticles that cover the pellet is metal-bonded again to bond the pellets to each other, whereby a molded body is manufactured. This achieves the object of the present invention.
The following thermoplastic resins are amorphous resins having a glass transition temperature lower than the thermal decomposition temperature of a complex composed of an inorganic metal compound. The glass transition temperature of polyvinyl chloride resin PVC is 80° C., the glass transition temperature of polycarbonate resin PS is 90° C., the glass transition temperature of acrylic resin PMMA is 100° C., the glass transition temperature of ABS resin is 100-125° C. The glass transition temperature of the polycarbonate resin PC is 145°C. Therefore, when using a molding material composed of these amorphous resins, a second suspension is prepared using a complex composed of an inorganic metal compound, and the temperature at which the second suspension is heated and compressed is controlled. , If the temperature is higher than the boiling point of the organic compound and is close to the thermal decomposition temperature of the complex, the pellet is compressed and deformed before the viscosity of the pellet is reduced, and the metal-bonded metal nanoparticles are collected following the deformation of the pellet. Are deformed, and the compression-deformed pellets are covered with a collection of metal-bonded metal nanoparticles. Further, a group of metal nanoparticles covering the compressed and deformed pellets are metal-bonded to each other, and the pellets are bonded to each other to manufacture a molded body.
The glass transition temperature of the amorphous resin excluding the PC resin is 100° C. or more lower than the thermal decomposition temperature of the complex. However, even when these molding materials are used, a collection of metal-bonded metal nanoparticles is deposited on the surface of the molding material in the second suspension. For this reason, when the organic compound is vaporized when the second suspension is heated and compressed, the viscosity is lower than that of the PC resin molding material. Covered with a collection of nanoparticles. That is, after the methanol is vaporized, a cluster of fine crystals of the metal compound is deposited on the surfaces of all the molding materials to produce the first suspension. Therefore, when the second suspension is produced, a collection of metal-bonded metal nanoparticles is deposited on the surfaces of all molding materials. As a result, when the organic compound is vaporized during the production of the molded body, all the molding materials are covered with a collection of metal-bonded metal nanoparticles.
Further, the following thermoplastic resins are amorphous resins having a glass transition temperature higher than the thermal decomposition temperature of a complex composed of an inorganic metal compound. The glass transition temperature of the polysulfone resin PSU is 190°C, the glass transition temperature of the polyarylate resin PAR is 193°C, the glass transition temperature of the polyphenylene ether resin PPE is 211°C, and the glass transition temperature of the polyetherimide resin PEI is 217°C. The glass transition temperature of the polyether sulfone resin PES is 225°C, and the glass transition temperature of the polyamideimide resin PAI is 280°C. Therefore, when using a molding material composed of these amorphous resins, a second suspension is prepared using a complex composed of an inorganic metal compound, and the temperature at which the second suspension is heated and compressed is controlled. , If the temperature is higher than the boiling point of the organic compound and is close to the glass transition temperature, the pellet will be compressed and deformed before the viscosity of the pellet is reduced, and the collection of metal-bonded metal nanoparticles will be deformed following the deformation of the pellet. The deformed pellets are then covered with a collection of metal-bonded metal nanoparticles. In addition, a group of metal nanoparticles covering the deformed pellets are metal-bonded to each other so that the pellets are bonded to each other, whereby a molded body made of an amorphous resin is manufactured.
Furthermore, when the glass transition temperature is a molding material composed of an amorphous thermoplastic resin higher than the thermal decomposition temperature of the metal octylate compound, a second suspension is prepared using the metal octylate compound, If the temperature at which the second suspension is heated and compressed is higher than the boiling point of the organic compound and is close to the glass transition temperature, the pellets are compression-deformed before the viscosity of the pellets is reduced, resulting in deformation of the pellets. Following this, the group of metal-bonded metal nanoparticles is deformed, and the deformed pellet is covered with the group of metal-bonded metal nanoparticles. Further, the aggregate of the metal nanoparticles covering the deformed pellets is metal-bonded to each other, so that the pellets are bonded to each other to manufacture a molded body.

On the other hand, since the crystalline thermoplastic resin has a high degree of crystallinity, the temperature at which the transition from the rubber-like flow state to the liquid flow state in which elasticity has been lost is completed, that is, the melting point clearly appears. Therefore, in the production of a molded body made of a crystalline resin, the molded material is heated to a temperature exceeding the melting point, the melted molded material is compressed and deformed, and the deformed molded materials are directly bonded to each other to form a molded body.
The object of the present invention is to produce a shaped body which is nonflammable and which does not self-ignite. Therefore, it is sufficient that the group of metal nanoparticles bonded to the metal covers the molding material, and the group of metal nanoparticles covering the molding material bonds to the molding material by metal bonding. On the other hand, the temperature of the molding machine or mold that heats and compresses the set of molding material is set higher than the boiling point of the organic compound and higher than the melting point of the molding material but close to the melting point, and the viscosity of the melted pellets decreases. The pellets are compressed and deformed before. Thus, after the organic compound has vaporized, the pellet is covered with a collection of metal-bonded metal nanoparticles. Further, a group of metal nanoparticles smaller by 5 digits than the pellet deforms following the deformation of the pellet, and the group of metal nanoparticles in which the deformed pellet is metal-bonded continues to be covered. In addition, the collection of metal nanoparticles is heated, the metal-bonded metal nanoparticles grow and become slightly coarse, and the slightly coarse metal nanoparticles re-metal bond. Therefore, the group of metal nanoparticles that are metal-bonded again covers the pellet, and the group of metal nanoparticles that covers the pellet is again metal-bonded and the pellets are bonded to each other. This achieves the object of the present invention.
Among the crystalline thermoplastic resins, the following synthetic resins have melting points lower than the thermal decomposition temperature of the complex composed of the inorganic metal compound. The low-density polyethylene resin LDPE has a melting point of 95-130°C, and the high-density polyethylene resin HDPE has a melting point of 120-140°C. The melting point of polypropylene resin PP is 168°C. The melting point of polyvinylidene fluoride resin PVDF is 134-169°C. Among polyamide resins PA, PA12 having a low melting point has a melting point of 179°C. The melting point of the polyacetal resin POM is 175°C. When a molding material composed of these crystalline resins is used, a second suspension is prepared using a complex composed of an inorganic metal compound, and the temperature at which the second suspension is heated and compressed is set to the organic compound. If the temperature is higher than the boiling point of the complex and the temperature is close to the thermal decomposition temperature of the complex, the pellet is compressed and deformed before the viscosity of the pellet is reduced, and the aggregate of metal-bonded metal nanoparticles is deformed following the deformation of the pellet. , A collection of metal-bonded metal nanoparticles covering the deformed pellet. In addition, a group of metal nanoparticles covering the deformed pellets are metal-bonded to each other, and the pellets are bonded to each other, whereby a molded body composed of the pellets is manufactured.
The melting point of the crystalline thermoplastic resin described below is higher than the thermal decomposition temperature of the complex composed of the inorganic metal compound and lower than the thermal decomposition temperature of the metal octylate compound. Polyethylene terephthalate resin PET has a melting point of 245° C., polyvinylidene chloride resin PVDC has a melting point of 210° C., PA6, which is the most popular polyamide resin PA, has a melting point of 225° C., PA66 has a melting point of 265° C., and polybutylene. The melting point of the terephthalate resin PBT is 232-267° C., the melting point of the polyphenylene sulfide resin PPS is 280° C., the melting point of the polychlorotrifluoroethylene resin PCTFE is 220° C., and the melting point of the cellulose acetate resin CA is 230° C. When using a molding material composed of these crystalline resins, a second suspension is prepared using a complex composed of an inorganic metal compound, and the temperature at which the second suspension is heated and pressurized is adjusted to the organic compound. The boiling point is higher than the melting point and higher than the melting point, but if it approaches the melting point, the pellet is compressed and deformed before the viscosity of the pellet decreases, and the collection of metal-bonded metal nanoparticles deforms following the deformation of the pellet. The deformed pellets are then covered with a collection of metal-bonded metal nanoparticles. In addition, a group of metal nanoparticles covering the deformed pellets are metal-bonded to each other and the pellets are bonded to each other, whereby a molded body is manufactured.
Further, the melting point of the following crystalline thermoplastic resin is higher than the thermal decomposition temperature of the metal octylate compound. The melting point of the perfluoroalkoxy fluororesin PFA is 310°C, and the melting point of the polytetrafluoroethylene resin PTFE is 327°C. The melting point of the liquid crystal polymer LCP is 370° C., which is higher than the thermal decomposition temperature of the metal laurate compound by 10° C. Therefore, the crystalline resin excluding the liquid crystal polymer uses a metal octylate compound as a raw material, and the liquid crystal polymer uses a metal laurate compound as a raw material to prepare a second suspension and heat the second suspension. If the temperature to pressurize is higher than the melting point but close to the melting point, the pellet is compressed and deformed before the viscosity of the pellet decreases, and the collection of metal-bonded metal nanoparticles deforms following the deformation of the pellet. The deformed pellets are then covered with a collection of metal-bonded metal nanoparticles. In addition, a group of metal nanoparticles covering the deformed pellets are metal-bonded to each other and the pellets are bonded to each other, whereby a molded body is manufactured.

Next, the fact that the molded article of the present invention described in paragraphs 25 to 27 has the property of being nonflammable and not self-igniting will be described from the thermal decomposition reaction of the polymer constituting the synthetic resin. The thermal decomposition reaction of the polymer is greatly different between the atmosphere in which oxygen gas is present and the nitrogen atmosphere. That is, thermal decomposition in an atmosphere containing oxygen gas is accompanied by heat generation because it is thermal decomposition due to oxidation reaction. This exothermic phenomenon accelerates the thermal decomposition of the polymer composed of an easily oxidizable organic substance, and the flammable gas generated during the thermal decomposition is self-ignited. On the other hand, in the thermal decomposition in the nitrogen atmosphere, the oxidation reaction does not occur, the thermal decomposition occurs due to the endothermic reaction, and the exothermic phenomenon does not occur. For this reason, the temperature at which the polymer starts thermal decomposition shifts to the high temperature side significantly later than in the atmosphere in which oxygen gas exists. For example, the thermal decomposition of the high-density polyethylene resin starts in the vicinity of 250° C. in the air atmosphere, while in the nitrogen atmosphere, the vicinity of 400° C. and 150° C. shift to the high temperature side.
On the other hand, the polymer is nitrogen atmosphere, methane with an ignition point of 537°C, ethane with an ignition point of 510°C, paraffinic hydrocarbon gas such as propane with an ignition point of 450°C, ethylene with an ignition point of 450°C, ignition. Olefinic hydrocarbon gas such as propylene having a point of 498°C, benzene having an ignition point of 498°C, aromatic hydrocarbon gas such as toluene having an ignition point of 480°C, tar having an ignition point higher than 500°C, ignition point Is decomposed into a liquid substance composed of monostyrene at 490°C.
The starting temperature and the ending temperature of the thermal decomposition of the synthetic resin in the nitrogen atmosphere are as follows. The polyacetal resin POM begins at 280°C and ends at 420°C. The polystyrene resin PS starts at 350° C. and ends near 460° C. The polyethylene terephthalate resin PET begins at 425°C and ends near 480°C. The polypropylene resin PP begins at 370°C and ends near 500°C. The high density polyethylene resin HDPE begins at 400°C and ends near 520°C. Polytetrafluoroethylene resin PTFE starts at 490°C and ends at around 640°C. In the case of polyvinyl chloride resin PVC resin, desorption of non-flammable and harmful hydrogen chloride gas HCl starts from around 220° C. accompanied by an endothermic reaction and rapidly progresses around 260° C. and continues up to 360° C. After that, thermal decomposition of the polymer accompanied by endotherm starts at around 420° C., benzene having an ignition point of 498° C. is formed, and ends at around 550° C., leaving 10% solid residue (ash). The thermal decomposition reaction of the novolac type phenolic resin starts desorption of the plasticizer at around 260°C and continues to around 360°C, after which thermal decomposition of the polymer with endotherm starts at 390°C and the ignition point is 715°C. And a liquid monomer such as cresol having an ignition point of 626° C. is produced, and the reaction is completed at around 700° C., leaving 65% of solid residue (ash content).
Therefore, even when the PP resin, the HDPE resin, and the PTFE resin are heated in a nitrogen atmosphere, when these resins are thermally decomposed, hydrocarbon gases such as propane, ethane, and toluene are generated, and further, these combustible materials are burned. When the volatile gas moves to the atmosphere and is heated above the ignition point, the flammable gas self-ignites and creates the starting point of the fire. Further, the PVC resin produces benzene by thermal decomposition, and when it is moved to the atmosphere and heated to 498° C. or higher, benzene self-ignites. Furthermore, the novolac-type phenolic resin is thermally decomposed to produce cresol, and when it is moved to the atmosphere and heated to 626° C. or higher, cresol self-ignites.
On the other hand, all the molding materials constituting the molded body of the present invention are covered with an airtight coating composed of a collection of metal-bonded metal nanoparticles. Therefore, the thermal decomposition of the polymer is completely different from the thermal decomposition in the nitrogen atmosphere. In other words, since the nitrogen atmosphere is an open atmosphere, the combustible gas generated by thermal decomposition is sequentially vaporized in the nitrogen atmosphere, so that the thermal decomposition proceeds as the temperature rises and the combustible gas is sequentially generated. The combustible gas is sequentially released into the nitrogen atmosphere. On the other hand, the polymer covered with the airtight coating in the present invention is such that the first combustible gas generated by pyrolysis is confined in a narrow region corresponding to the volume of the molding material, and the flammability in the narrow region is increased. The partial pressure of the gas increases, reaching a saturation pressure at that temperature, and thermal decomposition stops. Therefore, in order to proceed the thermal decomposition, it is necessary to give the polymer higher thermal energy than the thermal decomposition in the open atmosphere. Furthermore, an amount corresponding to 1 mol of the produced gas occupies a volume of 22.4 liters. For this reason, when a very small amount of combustible gas is generated, the partial pressure of the combustible gas in the narrow region becomes the saturation pressure at that temperature, and the combustible gas generated compared to the atmosphere of nitrogen gas The quantity is extremely small. In addition, since the first flammable gas is confined in the second and subsequent combustible gases generated by the thermal decomposition, the thermal decomposition does not proceed unless further large thermal energy is supplied. As a result, the molding material covered with the airtight coating in the present invention, the pyrolysis reaction proceeds at a temperature significantly higher than the pyrolysis temperature in the nitrogen atmosphere, and various flammable gases produced by the pyrolysis of the polymer are generated. Thermal decomposition occurs beyond the ignition point. Therefore, the molded article of the present invention does not self-ignite. Further, the airtight coating composed of a collection of metal-bonded metal nanoparticles has a certain bonding strength, and the coating is not destroyed by the partial pressure of the gas occupying a narrow region. As a result, oxygen gas is not supplied to the molding material, and the molding has incombustibility. As a result, the molded product of the present invention has the property of being nonflammable and not self-igniting.

Embodiment 2
The present embodiment is an embodiment relating to the complex composed of the inorganic metal compound described in paragraph 9. The metal compound according to the present invention has two properties of firstly dispersing in alcohol and secondly depositing metal by thermal decomposition. Here, copper is used as the metal, and as the copper compound having two properties, a copper complex composed of an inorganic metal compound having a copper complex ion in which a molecule or ion composed of an inorganic substance functions as a ligand to coordinate with the copper ion Explain that it is appropriate.
First, the alcohol dispersibility of an inorganic copper compound having a small molecular weight will be described. Inorganic copper compounds such as copper chloride, copper sulfate, and copper nitrate are dissolved in alcohol, copper ions are eluted, and many copper ions cannot participate in the deposition of copper fine particles. Further, inorganic copper compounds such as copper oxide, copper chloride and copper sulfide do not disperse in alcohols. Therefore, such an inorganic copper compound having a small molecular weight is not suitable as a copper compound because it has no property of being dispersed in alcohol.
On the other hand, copper compounds deposit copper by thermal decomposition. Among the chemical reactions in which copper is produced from a copper compound, the chemical reaction by the simplest treatment is a thermal decomposition reaction. That is, only by raising the temperature of the copper compound, the copper compound is thermally decomposed and copper is deposited. Furthermore, if the thermal decomposition temperature of the copper compound is low, it is possible to cover many molding materials of synthetic resin having a low melting point or softening point with fine particles of copper. Further, if the copper compound is easily synthesized, it becomes an inexpensive raw material for the copper fine particles. As such a copper compound, there is a copper complex composed of an inorganic metal compound having a copper complex ion that forms a ligand with a low-molecular weight molecule or ion composed of an inorganic substance and forms a ligand. That is, since the ligand has a low molecular weight, the number of ligands is small, and the molecular weight of the inorganic substance forming the inorganic metal compound is small, the thermal decomposition temperature of the copper complex is low. Furthermore, since the copper complex containing such a copper complex ion has a small molecular weight, it is easier and cheaper to synthesize than the copper complex containing another copper complex ion.
That is, the copper ion is the largest among the molecules constituting the copper complex. Incidentally, the covalent bond radius of the copper atom is 132±4 pm, while the covalent bond radius of the nitrogen atom is 71±1 pm, and the covalent bond radius of the oxygen atom is 66±2 pm. Therefore, in the molecular structure of the copper complex, a ligand composed of a molecule or an ion has the longest distance of a coordination bond portion that coordinates with the copper ion. Therefore, in the heat treatment, the coordination bond portion is first divided and decomposed into a metal and an inorganic substance, and copper is deposited after vaporization of the inorganic substance is completed.
As a copper complex ion in which a low-molecular weight molecule or ion made of such an inorganic substance serves as a ligand, an ammine complex in which ammonia NH ₃ serves as a ligand and forms a coordinate bond with a copper ion, or a chlorine ion Cl ⁻ , or Since a chloro complex in which chlorine ion Cl ⁻ and ammonia NH ₃ serve as ligands and coordinate-bonds to a copper ion is easier to synthesize than other copper complexes, it can be produced at a low cost among copper complexes. .. When a copper complex composed of such copper complex ions is heat-treated in a reducing atmosphere such as ammonia gas or hydrogen gas, the coordination bond site is first divided, and thermal decomposition is completed at a relatively low temperature of about 200° C. Is deposited. Further, it is dispersed in an alcohol such as methanol or n-butanol to a concentration of about 10% by weight. As such a copper complex, there is a copper complex having a tetraammine copper complex ion [Cu(NH ₃ ) ₄ ] ²⁺ or a hexaammine copper complex ion [Cu(NH ₃ ) ₆ ] ^2+, and an inorganic compound composed of such a copper complex ion. Examples thereof include tetraammine copper nitrate [Cu(NH ₃ ) ₄ ](NO ₃ ) ₂ or hexaammine copper sulfate [Cu(NH ₃ ) ₆ ]SO ₄ .
As the silver complex, for example, diammine silver chloride _{[Ag (NH 3) 2]} Cl, sulfate diammine silver _{[Ag (NH 3) 2]} 2 SO 4, nitric diammine silver _{[Ag (NH 3) 2]} NO 3 and so on. When such a silver complex is heat-treated in a reducing atmosphere, the coordination bond site is first divided, and the vaporization of the inorganic substance is completed at a low temperature of about 200° C. to deposit silver. Further, it is dispersed in methanol or n-butanol to a concentration of about 10% by weight.
As described above, in the complex composed of the inorganic metal compound, the ligand has a low molecular weight, the number of ligands is small, and the molecular weight of the inorganic substance forming the inorganic metal compound is small, so that the thermal decomposition temperature is the lowest. , Is the cheapest metal complex that is easy to synthesize. Therefore, the complex composed of the inorganic metal compound is a suspension in which the metal-bonded metal nanoparticles are deposited on the organic compound and serves as a first metal raw material for covering the molding material of the synthetic resin.
As described in paragraph 25, the softening point of the thermosetting resin is lower than the temperature at which the complex composed of the inorganic metal compound is thermally decomposed. Further, as described in paragraph 26, the glass transition temperature of some amorphous resins is lower than the thermal decomposition temperature of the complex. Therefore, when the molding material of these synthetic resins is covered with the suspension, a complex composed of an inorganic metal compound is used as a raw material of metal nanoparticles.

Embodiment 3
The present embodiment is an embodiment relating to the carboxylic acid metal compound described in the eleventh paragraph. That is, when the complex composed of the inorganic metal compound described in paragraph 29 is used as the first raw material of the metal nanoparticles covering the molding material, the metal carboxylate compound becomes the second raw material.
The metal compound according to the present invention has two properties of firstly dispersing in alcohol and secondly depositing metal by thermal decomposition. Here, it is explained that chromium is a metal and a chromium carboxylate compound is suitable as a substance having both properties.
First, the alcohol dispersibility of an inorganic chromium compound having a small molecular weight will be described. Inorganic chromium compounds such as chromium oxide Cr ₂ O ₃ , chromium chloride CrCl ₃ , and chromium nitrate Cr(NO ₃ ) ₃ are dissolved in alcohol, chromium ions Cr ³⁺ are eluted in the alcohol dispersion liquid, and many chromium ions are fine chromium particles. Can not participate in the precipitation. Inorganic chromium compounds such as chromium sulfate Cr(SO ₄ ) ₃ , chromium acetate Cr(CH ₃ COO) ₃ , and chromium phosphate CrPO ₄ do not disperse in alcohol. Such an inorganic chromium compound having a small molecular weight is not suitable as a chromium compound because it does not disperse in alcohol.
Among the inorganic chromium compounds, examples of inorganic chromium compounds having a chromium complex ion in which a low-molecular weight molecule or ion composed of an inorganic substance described in paragraph 28 has a chromium complex ion coordinate-bonded to a chromium ion include hexaammine chromium hydrochloride [ There is Cr(NH ₃ ) ₆ ]Cl ₃ . This chromium complex serves as the first raw material for the chromium fine particles that cover the molding material.
Here, the organic chromium compound will be described. The organic chromium compound deposits chromium by thermal decomposition. Among the chemical reactions in which chromium is produced from the organic chromium compound, the simplest chemical reaction is the thermal decomposition reaction. That is, only by raising the temperature of the organic chromium compound, chromium is deposited by thermal decomposition. Furthermore, if the pyrolysis temperature of the organic chromium compound is low, many synthetic resin molding materials can be covered with fine particles of chromium. Furthermore, if the synthesis of the organic chromium compound is easy, it becomes an inexpensive raw material for the chromium fine particles. As an organic chromium compound having such properties, there is a chromium carboxylate compound in which oxygen ions constituting a carboxyl group of a carboxylic acid are covalently bonded to chromium ions. Further, if the melting point or softening point of the synthetic resin is higher than the thermal decomposition temperature of the chromium carboxylate compound, the molding material can be covered with the metal-bonded chromium fine particles. Therefore, it is desirable that the pyrolysis temperature of the chromium carboxylate compound is low.
That is, of the ions forming the chromium carboxylate compound, the largest ion is the chromium ion. Therefore, if the oxygen ion forming the carboxyl group of the carboxylic acid is covalently bonded to the chromium ion, the distance between the chromium ion and the oxygen ion forming the carboxyl group is the longest among the ions. When the temperature of such a carboxylic acid chromium compound is raised in the atmosphere, when it exceeds the boiling point of the carboxylic acid, it decomposes into carboxylic acid and chromium. When the temperature is further raised, if the carboxylic acid is composed of a saturated fatty acid, the carboxylic acid is vaporized with heat of vaporization, and chromium is deposited after vaporization of the carboxylic acid. Since the thermal decomposition of the chromium carboxylate compound in the reducing atmosphere proceeds on a higher temperature side than the thermal decomposition in the atmospheric atmosphere, the thermal decomposition in the atmospheric atmosphere requires less heat treatment cost. Further, when the carboxylic acid is an unsaturated fatty acid, the carbon atoms become excessive with respect to the hydrogen atoms, so that when the chromium carboxylate compound composed of the unsaturated fatty acid is thermally decomposed, chromium oxide is deposited.
On the other hand, among chromium carboxylate compounds, a chromium carboxylate compound in which an oxygen ion forming a carboxyl group of a carboxylic acid functions as a ligand to approach a chromium ion to form a coordinate bond is a distance between the chromium ion and the oxygen ion. Is shortened, and conversely, oxygen ions have the longest distance between chromium ions and ions bound on the opposite side. In the thermal decomposition reaction of a chromium carboxylate compound having such a characteristic of the molecular structure, the bonding part between the oxygen ion and the ion bonded to the opposite side of the chromium ion is first divided, and as a result, chromium oxide is deposited.
Furthermore, the carboxylic acid chromium compound is an organic chromium compound that is easy to synthesize and cheapest because carboxylic acid is the most general-purpose organic acid. That is, when a carboxylic acid is reacted in a strong alkaline solution such as sodium hydroxide, an carboxylic acid alkali metal compound is produced. When this alkali metal carboxylate compound is reacted with an inorganic chromium compound such as chromium sulfate, a chromium carboxylate compound is produced. Therefore, it is the cheapest organic chromium compound among the organic chromium compounds.
That is, the composition formula of the chromium carboxylate compound is represented by Cr(COOR) ₃ . R is a hydrocarbon, the composition formula of which is C _m H _n (where m and n are integers). Among the substances constituting the chromium carboxylate compound, the chromium ion Cr ³⁺ located in the center of the composition formula is the largest. Therefore, when the chromium ion Cr ³⁺ and the oxygen ion O ⁻ forming the carboxyl group are covalently bonded, the distance between the chromium ion Cr ³⁺ and the oxygen ion O ⁻ becomes maximum. The reason for this is that the triple bond of the chromium atom has a covalent bond radius of 103 pm, the double bond of the oxygen atom has a covalent bond radius of 57 pm, and the double bond of the carbon atom has a covalent bond radius of 67 pm. .. When the carboxylic acid chromium compound having such a characteristic in molecular structure is used, when the boiling point of the carboxylic acid is exceeded, the bond between the chromium ion having the longest bonding distance and the oxygen ion constituting the carboxyl group is first broken, and the chromium compound is separated. And carboxylic acid. When the temperature is further raised, if the carboxylic acid is a saturated fatty acid, the carboxylic acid is vaporized with heat of vaporization, and chromium is deposited after the vaporization of the carboxylic acid is completed. Examples of the chromium carboxylate compound include chromium octylate, chromium laurate, and chromium stearate. Such a chromium carboxylate compound is dispersed in an alcohol such as methanol or n-butanol to a dispersion concentration of about 10% by weight. It is also an inexpensive industrial chemical that is commercially available as metal soap.
Further, if the saturated fatty acid has a low boiling point, the chromium carboxylate compound will thermally decompose at a low temperature. When the hydrocarbon constituting the saturated fatty acid has a long chain structure, the longer the long chain, that is, the larger the molecular weight of the saturated fatty acid, the higher the boiling point of the saturated fatty acid and the higher the thermal decomposition temperature. By the way, the boiling point of lauric acid having a molecular weight of 200.3 at atmospheric pressure is 296° C., and the boiling point of stearic acid having a molecular weight of 284.5 at atmospheric pressure is 361° C.
On the other hand, a saturated fatty acid having a branched chain structure has a shorter chain length and a lower boiling point than a saturated fatty acid having a straight chain structure. This causes thermal decomposition at a lower temperature. Further, since the saturated fatty acid having a branched chain structure is polar, the carboxylic acid copper compound composed of the saturated fatty acid having a branched chain structure is also polar and is dispersed at a relatively high ratio in a polar organic solvent such as alcohol. .. Octyl acid is a saturated fatty acid having such a branched structure. Octyl acid has a structural formula represented by CH ₃ (CH ₂ ) ₃ CH(C ₂ H ₅ )COOH, is branched by CH into an alkane of CH ₃ (CH ₂ ) ₃ and C ₂ H _5, and has a carboxyl group on CH. COOH binds. The boiling point of octylic acid at atmospheric pressure is 228°C, which is 68°C lower than that of lauric acid. Therefore, as a raw material for depositing chromium, copper octylate Cr(C ₇ H ₁₅ COO) ₃ is desirable. Chromium octylate undergoes thermal decomposition at 290° C. in the air atmosphere to deposit chromium.
Similarly, copper octylate Cu(C ₇ H ₁₅ COO) ₂ is used as the copper raw material, aluminum octylate Al(C ₇ H ₁₅ COO) ₃ is used as the aluminum raw material, and iron octylate Fe(C ₇ ) is used as the iron raw material. H ₁₅ COO) ₃ is preferably nickel octylate Ni(C ₇ H ₁₅ COO) ₂ as a raw material of nickel. As described above, the metal octylate compound is composed of various metal ions, and is a suspension in which the metal-bonded metal nanoparticles are deposited on the organic compound and serves as a second raw material for covering the molding material of the synthetic resin.
On the other hand, as described in paragraph 26, the amorphous resin having the highest glass transition temperature is a polyamideimide resin having a glass transition temperature of 280°C. Further, as described in paragraph 27, the crystalline resin having the highest melting point is a liquid crystal polymer having a melting point of 370°C. The thermal decomposition temperature of the metal octylate compound is 290°C, and the thermal decomposition temperature of the metal laurate compound is 360°C. Therefore, when covering a molding material composed of an amorphous resin having a glass transition point higher than the thermal decomposition temperature of a complex composed of an inorganic metal compound and a crystalline resin excluding a liquid crystal polymer with a suspension, the metal octylate compound is used. The metal laurate compound is used as a raw material for metal nanoparticles only when a molding material made of a liquid crystal polymer is used as a raw material for metal nanoparticles.

Example 1
This example is an example of producing a suspension in which a group of metal-bonded copper nanoparticles is deposited on the surface of a phenol resin molding material and the group of the molding material is dispersed in an organic compound. As a raw material of copper nanoparticles, tetraammine copper nitrate [Cu(NH ₃ ) ₄ ] (NO ₃ ) ₂ (for example, a product of Mitsuwa Chemical Co., Ltd.) having a thermal decomposition temperature of 200° C. described in paragraph 29 is used. I was there. In addition, as the organic compound, diethylene glycol having a boiling point of 244°C, a melting point of -10.5°C, and a viscosity of 20°C and a viscosity of 36 mPa sec (for example, a product of Nippon Shokubai Co., Ltd.) is used as the organic compound. I was there. The viscosity of diethylene glycol is 61 times that of methanol. Further, pellets having a softening point of 120 to 126° C. (for example, AH-PM(H), a product of Meiwa Kasei Co., Ltd.) were used as a molding material of the phenol resin. Note that the melting point of copper is 1085° C., it reacts with oxygen in the atmosphere to form a cupric oxide CuO film, and the film has the property of preventing further oxidation.
First, 51 g (corresponding to 0.2 mol) of tetraammine copper nitrate was dispersed in methanol so as to be 10% by weight, and diethylene glycol was mixed at 10% by weight with this dispersion. 1.1 kg of pellets previously dried by a dehumidifying dryer were mixed with this mixed solution. This mixture was placed in a container and heat-treated in a hydrogen gas atmosphere. First, the temperature was raised to 65° C. to vaporize the methanol, and the mixture was allowed to stand at 210° C. for 1 minute to thermally decompose the tetraammine copper nitrate to prepare Sample 1. Further, a part of sample 1 was taken out and placed in a container, heated to 245° C. in the air atmosphere, and diethylene glycol was vaporized to prepare sample 2.
Next, the sample 1 and the sample 2 were observed with the electron microscope. As the electron microscope, an extremely low accelerating voltage SEM owned by JFE Techno Research Co., Ltd. was used. This device is capable of observing the surface with an extremely low acceleration voltage from 100 V, and the surface can be directly observed without forming a conductive film.
First, with respect to the reflected electron beams from the surfaces of the sample 1 and the sample 2, a secondary electron beam between 900 and 1000 V was extracted and image processing was performed. The entire surfaces of the two types of samples were covered with a collection of particulate particles having a size of 40-60 nm.
Next, the reflected electron beams from the surfaces of the two types of samples were subjected to image processing by extracting energy in the range of 900 to 1000 V, and the material of the particles was analyzed by the lightness and darkness of the images. No shade was observed in any of the granular particles, indicating that the particles were composed of a single atom.
Further, the energy of the characteristic X-rays from the surface of the two kinds of samples and the intensity thereof were image-processed, and the kinds of elements constituting the particles were analyzed. Since the granular fine particles were composed only of copper atoms, the granular fine particles on the surfaces of the two types of samples were copper granular fine particles.
Further, the surface resistance of Sample 2 was measured at a plurality of locations with a surface resistance meter (for example, surface resistance meter ST-4 manufactured by Simco Japan Co., Ltd.). Since the surface resistance value was 1×10 ⁶ Ω/□, it had a surface resistance close to that of a metal.
Further, the sample 2 was cut and a plurality of cross sections were observed with an electron microscope. With respect to reflected electron beams from a plurality of cross sections, secondary electron beams lying between 900 and 1000 V were extracted and image processing was performed. Granular particles were stacked and bonded in a thickness of about 6 layers to cover the pellet.
From the above observation results, Sample 2 is a set of pellets in which the pellets are covered with a set of copper nanoparticles in which copper nanoparticles are stacked and bonded in a thickness of about 6 layers. Thereby, the surface resistance of the pellet had a surface resistance close to that of metal. In addition, Sample 1 is a suspension in which a collection of copper nanoparticles is deposited on the surface of the pellets in a stack of about 6 layers and bonded, and the collection of the copper nanoparticles is dispersed in diethylene glycol. Is.
The phenol resin pellets have a softening point of 120 to 126°C and are gelled at 150°C for 70 to 86 seconds. That is, the pellet is gelated in the process of thermally decomposing the complex of the inorganic metal compound. On the other hand, when methanol is vaporized during the preparation of sample 1, a cluster of fine crystals of tetraammine copper nitrate precipitates on the surface of the pellets, the surface of the pellets is covered with the clusters of fine crystals, and the pellets are dispersed in diethylene glycol. Suspension. When the temperature is further raised, the pellet is softened, but the collection of fine crystals continues to cover the softened pellet. Further, when the process of pyrolyzing tetraammine copper nitrate is reached, the pellets are gelled, but the gelled pellets having a predetermined viscosity continue to be covered with a collection of fine crystals. Therefore, a collection of fine crystals is thermally decomposed on the surface of the gelled pellet, a collection of metal-bonded copper nanoparticles is deposited on the surface of the gelled pellet, and this pellet is a suspension dispersed in diethylene glycol. Is prepared and the sample 1 is obtained. Since the gelled pellets were only exposed to 210° C. for a short time, the pellet polymerization reaction did not proceed.
From the above results, it was possible to produce a suspension in which a group of metal-bonded copper nanoparticles was deposited on the surface of the phenol resin molding material, and the group of the molding material was dispersed in the organic compound. Note that this embodiment is merely an example. The thermosetting resin described in paragraph 25, which has a lower softening point with respect to the thermal decomposition temperature of the complex composed of an inorganic metal compound, is the amorphous resin described in paragraph 26, which has a lower glass transition temperature. -Based thermoplastic resin or the crystalline thermoplastic resin whose melting point is lower than the thermal decomposition temperature of the metal octylate compound described in paragraph 27 is used as a molding material, and further comprises the inorganic metal compound described in paragraph 29. When the complex is used as a raw material for metal nanoparticles, suspensions having various material constitutions can be produced.

Example 2
In this example, 102 g (corresponding to 0.4 mol), which is twice the amount of tetraammine copper nitrate in Example 1, was dispersed in methanol so that the concentration was 10% by weight, and diethylene glycol was 10% by weight in this dispersion. As mixed. In the same manner as in Example 1, 1.1 kg of phenol resin pellets were mixed with this mixed solution. This mixture was put in a container, methanol was vaporized in the same manner as in Example 1, and then heat-treated at 210° C. in a hydrogen gas atmosphere to prepare Sample 3. Further, as in Example 1, a part of Sample 3 was taken out, placed in a container, and heat-treated at 245° C. in the air atmosphere to prepare Sample 4.
As in Example 1, Sample 3 and Sample 4 were observed with an electron microscope. Further, as a result of measuring the surface resistance of Sample 4, the surface resistance was 1×10 ⁴ Ω/□, and the surface resistance was closer to that of metal than Sample 2. Furthermore, as a result of slicing the sample 4 and observing a plurality of sections in a cross section with an electron microscope, a group of fine particles in which fine particles were stacked and bonded in a thickness of about 12 layers covered the pellet.
As a result, in the sample 4, the pellets are covered with a collection of copper nanoparticles in which copper nanoparticles are stacked and bonded to each other with a thickness of about 12 layers, and this is a collection of pellets. Further, Sample 3 is a suspension in which a collection of copper nanoparticles in which copper nanoparticles are stacked and bonded to each other with a thickness of about 12 layers is deposited on the surface of the pellet, and the collection of the pellet is dispersed in diethylene glycol. ..
From the above results, the thickness of the metal nanoparticles to which the metal nanoparticles covering the pellets of the synthetic resin are stacked and bonded is determined by the amount of the complex of the inorganic metal compound dispersed in methanol with respect to the amount of the pellets used. Therefore, when forming a molded body using a suspension as a raw material, when imparting conductivity and thermal conductivity close to that of a metal to the molded body, methanol of a complex consisting of an inorganic metal compound relative to the amount of pellets used is used. It is sufficient to increase the amount of dispersion.

Example 3
In this example, a group of chromium nanoparticles in which chromium nanoparticles are stacked and bonded is deposited on the surface of a molding material of a polyether sulfone resin PES, and the group of the pellets is dispersed in an organic compound. It is an example of manufacturing. The chromium octylate Cr(C ₇ H ₁₅ COO) ₃ (for example, a product of Wako Pure Chemical Industries, Ltd.) described in paragraph 30 was used as a raw material for the chromium nanoparticles. Further, as an organic compound, benzyldiglycol having a property of having a boiling point of 302° C., a melting point of −50° C., and a viscosity of 20° C. of 19.3 mPa sec as described in the 34th paragraph (for example, a product of Nippon Emulsifier Co., Ltd.). Was used. The viscosity of benzyldiglycol is 33 times that of methanol. Further, pellets having a glass transition temperature of 225° C. (for example, Sumika Excel 4100G manufactured by Sumitomo Chemical Co., Ltd.) were used as the polyether sulfone resin. In addition, since the melting point of chromium is as high as 1907° C. and the surface immediately forms a passivation of chromium oxide Cr ₂ O ₃ , it has a property of being resistant to rust.
First, 96 g (corresponding to 0.2 mol) of chromium octylate was dispersed in methanol so as to be 10% by weight, and benzyldiglycol was mixed at 20% by weight with this dispersion. 1.2 kg of pellets previously dried by a dehumidifying dryer were mixed with this mixed solution. Next, this mixture was put into a container and heat-treated in an air atmosphere. First, the temperature was raised to 65° C. to vaporize methanol, and the mixture was allowed to stand at 290° C. for 1 minute to thermally decompose chromium octylate to prepare sample 5. Further, a part of the sample 5 was taken out and put in a container, heated to 305° C. in the air atmosphere to vaporize benzyldiglycol, and a sample 6 was prepared.
Next, Sample 5 and Sample 6 were observed with an electron microscope in the same manner as in Example 1. First, with respect to the reflected electron beams from the surfaces of the two types of samples, secondary electron beams in the range of 900 to 1000 V were extracted and image processing was performed. In all parts of the surface of the sample, granular fine particles having a size of 40-60 nm covered the entire surface.
Next, the reflected electron beams from the surfaces of the two types of samples were subjected to image processing by extracting energy in the range of 900 to 1000 V, and the material of the particles was analyzed by the lightness and darkness of the images. Since no gradation was observed in any of the granular particles, it was found that they consist of a single atom.
Further, the energy of the characteristic X-rays from the surface of the two kinds of samples and the intensity thereof were image-processed, and the kinds of elements constituting the particles were analyzed. Since the granular particles were composed only of chromium atoms, they were chromium granular particles.
Further, as for the sample 6, the surface resistance at a plurality of locations was measured by a surface resistance meter in the same manner as in Example 1. Since the surface resistance value was 1×10 ⁷ Ω/□, it had a surface resistance close to that of metal.
Further, the sample 6 was cut and a plurality of cross sections were observed with an electron microscope. With respect to reflected electron beams from a plurality of cross sections, secondary electron beams lying between 900 and 1000 V were extracted and image processing was performed. Granular particles were stacked and bonded to each other with a thickness of about 6 layers to cover the surface of the pellet.
From the above results, in the sample 6, the aggregate of the chromium nanoparticles in which the chromium nanoparticles are stacked and bonded to each other in the thickness of about 6 layers covers the pellet, and the aggregate of the pellet is formed. Thereby, the surface resistance of the pellet had a surface resistance close to that of metal. Sample 5 is a suspension in which a collection of chromium nanoparticles, in which a collection of chromium fine particles are stacked and bonded to each other in a thickness of about 6 layers, is deposited on the surface of the pellet, and the collection of the pellet is dispersed in benzyldiglycol. ..
From the above results, a cluster of metal-bonded chromium nanoparticles was deposited on the surface of the PES resin pellet, and a suspension in which the pellet cluster was dispersed in an organic compound could be manufactured. Note that this embodiment is merely an example. With respect to the thermal decomposition temperature of the complex composed of the inorganic metal compound, the amorphous thermoplastic resin described in paragraph 26, which has a higher glass transition temperature, or the thermal decomposition temperature of the metal octylate compound, When the crystalline thermoplastic resin described in paragraph 27, which has a higher melting point, is used as a molding material, and the metal octylate compound described in paragraph 30 is used as a raw material for metal nanoparticles, various materials can be obtained. A suspension of composition can be produced.

Example 4
In this example, 192 g (corresponding to 0.4 mol), which is twice the amount of chromium octylate used in Example 3, was dispersed in methanol so as to be 10% by weight, and benzyldiglycol was added to this dispersion. It was mixed so as to be 10% by weight. 1.2 kg of polyethersulfone resin pellets were mixed with this mixed solution in the same manner as in Example 3. This mixture was put in a container, methanol was vaporized in the same manner as in Example 3, and then heat-treated at 290° C. in the air atmosphere to prepare Sample 7. Further, a part of Sample 7 was taken out and heat-treated at 305° C. in the air atmosphere to prepare Sample 8.
As in Example 3, Sample 7 and Sample 8 were observed with an electron microscope. Further, as a result of measuring the surface resistance of Sample 8, the surface resistance was 1×10 ⁵ Ω/□, which was closer to that of metal than Sample 6. Further, as a result of cutting the sample 8 and observing a plurality of cross-sections with an electron microscope, it was found that chromium nanoparticles having a size of 40-60 nm were stacked and bonded to each other with a thickness of about 12 layers to cover the pellet. As a result, in the sample 8, a group of chromium nanoparticles in which chromium nanoparticles are stacked and bonded to each other with a thickness of about 12 layers covers the pellet, and the pellet is composed of the pellet. Further, Sample 7 is a suspension in which a group of chromium nanoparticles in which chromium nanoparticles are stacked in a thickness of about 12 layers and bonded to each other is deposited on the surface of the pellet, and the pellet group is dispersed in diethylene glycol.
From the above observation results, as in Example 2, the thickness of the metal nanoparticles to which the metal nanoparticles covering the synthetic resin pellets are stacked and bonded is determined by the dispersion of the metal octylate compound in methanol with respect to the amount of the pellets used. It depends on the quantity. Therefore, when the molded body is provided with conductivity and thermal conductivity close to that of a metal when the molded body is molded, the amount of the metal octylate compound dispersed in methanol may be increased with respect to the amount of the pellets used.

Example 5
This example is an example of producing a suspension in which a collection of metal-bonded copper nanoparticles is deposited on the surface of a polyethylene terephthalate PET resin molding material, and the molding material is dispersed in an organic compound. The raw material of the copper nanoparticles is the tetraammine copper nitrate [Cu(NH ₃ ) ₄ ](NO ₃ ) ₂ used in Example 1. Further, the organic compound is a phenylpropylene glycol (for example, a product of Nippon Shokubai Co., Ltd.) having a property of having a boiling point of 243° C., a melting point of 12.5° C., and a viscosity of 20° C. and a viscosity of 23 mPa sec described in the 34th paragraph. is there. The viscosity of this organic compound is 39 times that of methanol. Further, as the PET resin having a melting point of 245° C., a pellet of a commercially available recycled molding material was used.
First, 51 g (corresponding to 0.2 mol) of tetraammine copper nitrate was dispersed in methanol so as to be 10% by weight, and phenylpropylene glycol was mixed at 15% by weight with this dispersion. 1.2 kg of pellets that had been washed and dried in advance were mixed with this mixed solution. This mixture was placed in a container and heat-treated in a hydrogen gas atmosphere. First, the temperature was raised to 65° C. to vaporize the methanol, and the mixture was allowed to stand at 200° C. for 5 minutes to thermally decompose tetraammine copper nitrate to prepare Sample 9. Further, a part of the sample 9 was taken out and placed in a container, heated to 243° C. in the air atmosphere to vaporize phenylpropylene glycol, and a sample 10 was prepared.
As in Example 1, Sample 9 and Sample 10 were observed with an electron microscope. In addition, as a result of measuring the surface resistance of Sample 10, the surface resistance was 1×10 ⁶ Ω/□, which was close to that of a metal. Further, as a result of cutting the sample 10 and observing a plurality of sections in a cross section with an electron microscope, a group of fine particles in which fine particles were stacked and bonded with a thickness of about 6 layers covered the pellet.
As a result, the sample 10 is a set of pellets in which the pellets are covered with a set of copper nanoparticles in which copper nanoparticles are stacked and bonded in a thickness of about 6 layers. Sample 9 is a suspension in which a collection of copper nanoparticles in which copper nanoparticles are stacked and bonded in a thickness of about 6 layers is deposited on the surface of the pellet, and the collection of the pellet is dispersed in phenylpropylene glycol. ..
From the above results, a cluster of metal-bonded copper nanoparticles was deposited on the surface of the PET resin molding material, and a suspension in which the cluster of the molding material was dispersed in the organic compound could be manufactured. Note that this embodiment is merely an example. With respect to the thermal decomposition temperature of the complex composed of an inorganic metal compound, the thermosetting resin described in paragraph 25 having a lower softening point and the amorphous described in paragraph 26 having a lower glass transition temperature. Or a crystalline thermoplastic resin having a melting point lower than the thermal decomposition temperature of the metal octylate compound is used as a molding material. When the complex composed of the inorganic metal compound described above is used as a raw material for metal nanoparticles, suspensions having various material configurations can be produced.

Example 6
This example is an example of producing a suspension in which a group of metal-bonded chromium nanoparticles is deposited on the surface of a perfluoroalkoxy fluororesin PFA molding material, and the molding material is dispersed in an organic compound. .. The raw material for the chromium nanoparticles is the chromium octylate used in Example 3. In addition, as the organic compound, tetraethylene glycol (for example, a product of Nippon Shokubai Co., Ltd.) having the property of having a boiling point of 329° C., a melting point of −5.6° C., and a viscosity of 20° C. of 55 mPa seconds as described in the 33rd paragraph is used. Using. As the molding material, pellets of perfluoroalkoxy fluororesin PFA having a melting point of 310° C. (for example, product AP-230 manufactured by Daikin Industries, Ltd.) were used.
First, 96 g of chromium octylate (corresponding to 0.2 mol) was dispersed in methanol so as to be 10% by weight, and tetraethylene glycol was mixed at 10% by weight with this dispersion. 1.2 kg of pellets previously dried by a dehumidifying dryer were mixed with this mixed solution. Next, this mixture was put into a container and heat-treated in an air atmosphere. First, the temperature was raised to 65° C. to vaporize methanol, and the mixture was allowed to stand at 290° C. for 1 minute to thermally decompose chromium octylate to prepare Sample 11. Further, a part of Sample 5 was taken out and placed in a container, heated to 330° C. in the air atmosphere to vaporize tetraethylene glycol, and Sample 12 was prepared.
Similar to Example 3, Sample 11 and Sample 12 were observed with an electron microscope. Moreover, as a result of measuring the surface resistance of Sample 12, the surface resistance was 1×10 ⁷ Ω/□. Further, as a result of cutting the sample 12 and observing a plurality of sections in a cross section with an electron microscope, it was found that chromium nanoparticles having a size of 40-60 nm were stacked and bonded in a thickness of about 6 layers to cover the pellet. As a result, in the sample 12, a group of chromium nanoparticles in which chromium nanoparticles are stacked and bonded to each other with a thickness of about 12 layers covers the pellet, and the sample 12 is composed of the pellet. In addition, Sample 11 is a suspension in which a group of chromium nanoparticles in which chromium nanoparticles are stacked and bonded to each other in a thickness of about 6 layers is deposited on the surface of the pellet, and the pellet group is dispersed in diethylene glycol.
From the above results, it was possible to manufacture a suspension in which a group of metal-bonded chromium nanoparticles was precipitated on the surface of the PFA resin pellet, and the group of the molding material was dispersed in the organic compound. Note that this embodiment is merely an example. Compared to the thermal decomposition temperature of the metal octylate compound, an amorphous thermoplastic resin having a higher glass transition temperature and a crystalline thermoplastic resin having a higher melting point are used as a molding material. When the compound is used as a raw material for metal nanoparticles, suspensions having various material constitutions can be produced.

Example 7
In this example, using the sample 1 manufactured in the example 1 and the sample 3 manufactured in the example 2, a packing 1 having a thickness of 2 mm shown in FIG. 1 was manufactured by a compression molding method. The cavity having the outer shape of the packing 1 was preheated to 244° C., which is the boiling point of diethylene glycol. A molding machine having an inner shape of the packing 1 was preheated to 255°C. This cavity is filled with sample 1 or sample 3, the molding machine is lowered into the cavity, and a pressure of increasing the pressure to 20 MPa in 30 seconds is applied to sample 1 or sample 3 in the cavity by the molding machine and left for 30 seconds. did. After that, the pressure of the molding machine was released, and the gas of diethylene glycol in the cavity was sucked by the recovery machine. Further, a pressure of 30 MPa was applied to the samples 1 to 3 in the cavity by the molding machine. The molding machine was pulled up, and the packing 1 in the cavity was taken out.
Next, a part of the packing 1 molded using Sample 1 or Sample 3 was cut out as Sample 13 or Sample 14, and the surface and the cut surface were observed with an electron microscope as in Example 1. Unlike the samples 1 and 3, the surfaces of both packings 1 were covered with a cluster of copper nanoparticles coarsened to a size of 50 to 70 nm. Further, the cross section of Sample 13 was different from Sample 2, and the coarse copper nanoparticles were stacked and bonded to each other with a thickness of about 5 layers to cover the pellet. Sample 14 was different from Sample 4 in that coarse copper nanoparticles were stacked and bonded to each other with a thickness of about 10 layers to cover the pellet.
Two pieces of each of the two kinds of packing 1 were dropped from a height of 2 m, but only slight dents were formed, and none of the packing 1 was broken. Therefore, it was found that the molded product in which the molding materials are bonded to each other by the aggregate of copper nanoparticles has a certain mechanical strength.
Further, two of each of the two kinds of packings 1 are left for 5 minutes in a heat treatment furnace heated to 800° C. in an air atmosphere, the packing 1 is taken out, and a part of the packing 1 is cut out as a sample 15 and a sample 16. As in Example 1, the surface and the cut surface were observed with an electron microscope. The surface of both packings 1 was in a smooth state of dark red. Further, as a result of image-processing the energy of the characteristic X-rays from the surface of the sample 15 and the surface of the sample 16 and its intensity and analyzing the kinds of elements constituting the surface, the surface was composed of cupric oxide CuO. In addition, as a result of observing the cross section of Sample 15 and the cross section of Sample 16 with an electron microscope, unlike Samples 13 and 14, all the pellets were decomposed into a black liquid substance and solid ash. Further, in Sample 15, the grain boundaries of the copper nanoparticles covering the pellets of Sample 13 disappeared, and all the pellets were covered with a wavy film having a thickness of about 300 nm made of a continuous bulk of copper. Further, in Sample 16, the grain boundaries of the copper nanoparticles covering the pellets of Sample 14 disappeared, and all the pellets were covered with a wavy film having a thickness of about 600 nm made of a continuous bulk of copper.
As described above, as a result of the heat treatment at 800° C. in the air atmosphere, the surface layer of the packing 1 was oxidized to cupric oxide, but inside the packing 1, all the pellets were covered with the copper film. The thermal decomposition proceeded and was decomposed into a liquid substance and solid ash. Therefore, the pellets constituting the packing 1 are shielded from the outside by the copper coating, and the packing 1 has the property of being nonflammable and not self-igniting. In addition, the collection of metal-bonded copper nanoparticles covering the pellets showed that the nanoparticles grew and the grain boundaries coarsened as the temperature increased, and the temperature increased to 800° C. It is thought that the field disappeared and the film was changed to a continuous bulk copper film. Therefore, in order to provide the packing with at least 800° C. non-combustibility and the property of not self-igniting, a suspension obtained by forming six layers of copper nanoparticles in a stack and stacking them together may be used as a raw material.
Further, in the present embodiment, the packing having the non-combustibility and the property of not self-igniting was manufactured by the compression molding method, but the manufacturing of the packing is only an example. The shape of the cavity filled with the suspension can be freely changed, and the shape of the molding machine for pressurizing the suspension filled in the cavity can be freely changed. Therefore, not only the packing but also molded articles having various shapes and having nonflammability and self-ignition characteristics can be manufactured. Further, the molding material is not limited to the phenol resin, and as described in the paragraph 35 of Example 1, various molding materials composed of other thermosetting resin, amorphous thermoplastic resin or crystalline thermoplastic resin. Can be used. In addition, the metal nanoparticles that bind the molding material are not limited to the copper nanoparticles, but by using the complex composed of the inorganic metal compound described in the paragraph 29, the molding material is bonded to a group of nanoparticles composed of various metals. Can be made

Example 8
In this example, using the sample 1 manufactured in the example 1 and the sample 3 manufactured in the example 2, a gear 2 having a thickness of 5 mm shown in FIG. 2 was manufactured by a transfer molding method. The cavity formed by a pair of molds into which the sample 1 or the sample 3 is pushed has the shape of the gear 2 inside.
The pot filled with the sample was previously heated to 244° C., which is the boiling point of diethylene glycol. Further, the temperature of the pair of molds into which the sample was pushed was raised to 255° C. in advance. Next, the pot was filled with Sample 1 or Sample 3. Further, the sample 1 or the sample 3 was pushed into the clamped mold with a pressure of 30 MPa by the plunger installed in the pot. After that, pressurization of the plunger was once stopped, and the gas in the mold was sucked by the collector. Further, the plunger was applied to the sample in the mold to increase the pressure to 40 MPa in 30 seconds, and the sample was held for 30 seconds. Then, the plunger was pulled up, the mold was opened, and the gear 2 was taken out.
Next, a part of the molded gear 2 was cut out as a sample 17 or a sample 18, and the surface and the cut surface were observed with an electron microscope in the same manner as in Example 1. Unlike the samples 2 and 4, the surfaces of both gears 2 were covered with aggregates of coarse copper nanoparticles having a size of 50 to 70 nm. Unlike the sample 2, the cross section of the sample 17 was such that copper nanoparticles were stacked and bonded with a thickness of about 5 layers to cover the pellet. Further, unlike sample 4, sample 18 had copper nanoparticles stacked and bonded to each other with a thickness of about 10 layers to cover the pellet.
Two of the two kinds of gears 2 were dropped from a height of 2 m, but only slight dents were formed and none of the gears 2 was broken. Therefore, it was found that the molded product in which the molding materials are bonded to each other by the aggregate of copper nanoparticles has a certain mechanical strength.
Further, two of each of the two kinds of gears 2 were left at 800° C. for 5 minutes in the air atmosphere in the same manner as in Example 7, then the molded product was taken out, and a part of the molded product was sample 19 and the sample. Cut out as 20, and in the same manner as in Example 1, the surface and the cut surface were observed with an electron microscope. The surfaces of both gears 2 were in a smooth state of dark red as in Example 7, and the surfaces were composed of cupric oxide CuO. In addition, as a result of observing the cross section of Sample 19 and the cross section of Sample 20 with an electron microscope, all the pellets were decomposed into a black liquid substance and solid ash as in Example 7. Further, in the sample 19, the grain boundaries of the copper nanoparticles covering the pellets of the sample 17 disappeared, and all the pellets were covered with the wavy film having a thickness of about 300 nm made of a continuous bulk of copper. Further, in Sample 20, the grain boundary of the copper nanoparticles covering the pellet of Sample 18 disappeared, and the sample 20 was covered with a corrugated film having a thickness of about 600 nm and formed of a continuous bulk of copper.
As described above, as a result of heat-treating gear 2 at 800° C. in the air atmosphere, as in Example 7, the surface layer of gear 2 was oxidized to cupric oxide, but inside gear 2 was Thermal decomposition proceeded in a state where the pellets were covered with the copper film, and decomposed into a liquid substance and solid ash. Therefore, all the pellets constituting the gear 2 are shielded from the outside by the copper coating, and the gear 2 has the property of being nonflammable and not self-igniting. Therefore, in order to give the gear a non-combustible property at least 800° C. and a property of not self-igniting, as in Example 7, a suspension obtained by stacking pellets of copper nanoparticles in six layers and binding them together. It has been found that can be used as a raw material.
Further, in this embodiment, a gear having a non-combustibility and a property of not self-igniting was manufactured by the transfer molding method, but the manufacture of the gear is merely an example. Since the shapes of the pair of molds into which the suspension is pushed can be freely changed, not only gears but also various shapes of non-combustible and self-igniting molded articles can be manufactured. Further, the molding material is not limited to the phenol resin, and as described in paragraph 35, various molding materials made of other thermosetting resin, amorphous thermoplastic resin or crystalline thermoplastic resin may be used. it can. In addition, the metal nanoparticles that bind the molding material are not limited to the copper nanoparticles, but by using the complex composed of the inorganic metal compound described in the paragraph 29, the molding material is bonded to a group of nanoparticles composed of various metals. Can be made
As described above, using the suspension in which the molding material is the phenol resin, the molded body was manufactured by the compression molding method in Example 7 and by the transfer molding method in Example 8. As the molding material, not only phenol resin but also other thermosetting resin can be used. As described in paragraph 25, pellets having a softening point exceeding the softening point can be used as long as they are molding methods other than the extrusion molding method and the air blow molding method. Or, a large pressing force can be applied to the aggregate of the powder and granules, and a molded body having various shapes and nonflammability and non-self-ignition property can be manufactured by various molding methods.

Example 9
In this example, using the sample 5 manufactured in the example 3 and the sample 7 manufactured in the example 4, the helical internal gear 3 shown in FIG. 3 was manufactured by an injection molding method. Therefore, the cylinder for filling the sample 5 or the sample 7 is preheated to 302° C., which is the boiling point of benzyldiglycol, and the mold for injecting the sample 5 or sample 7 is preheated to 315° C. did. Next, the sample 5 or the sample 7 is filled in the cylinder, and thereafter, the pressure applied to the sample 5 is continuously increased by moving the screw installed in the cylinder in increments of 10 MPa in three steps. Or, in addition to Sample 7, it was injected into the mold. After that, pressurization by the screw was once stopped, and benzyldiglycol in the mold was sucked from the outside of the cylinder by a collector. Furthermore, the pressure in the mold was increased to 40 MPa by moving the screw, which was applied to the sample in the mold. After that, the mold was opened and the helical internal gear 3 was taken out.
Next, a part of the helical internal gear 3 molded by using Sample 5 or Sample 7 was cut out as Sample 21 or Sample 22, and the surface and the cut surface were observed by an electron microscope as in Example 1. The surfaces of both helical internal gears 3 were covered with aggregates of coarse chrome nanoparticles with a size of 50-70 nm, unlike the surfaces of Samples 6 or 8. The cross section of Sample 21 was different from the cross section of Sample 6, and coarsened nanoparticles of chromium were stacked and bonded in a thickness of about 5 layers to cover the pellet. The cross section of the sample 22 was different from the cross section of the sample 8, and the coarsened chromium nanoparticles were stacked and bonded to each other with a thickness of about 10 layers to cover the pellet.
Also, two of each of the two types of helical internal gears 3 were dropped from a height of 2 m, but only slight dents were formed and the helical internal gears 3 were not broken. For this reason, a molded product in which the molding materials are bonded to each other by a collection of chromium nanoparticles has a certain mechanical strength.
Further, two of each of the two types of helical gears 3 were left at 800° C. for 5 minutes in the air atmosphere in the same manner as in Example 7, after which the molded product was taken out and a part of the molded product was removed. Samples 23 and 24 were cut out, and the surface and the cut surface were observed with an electron microscope as in Example 1. The surfaces of both helical internal gears 3 were in a smooth state of dark green and were composed of chromium oxide Cr ₂ O ₃ . Further, as a result of observing the cross section of Sample 23 and the cross section of Sample 24 with an electron microscope, all the pellets were decomposed into a black liquid substance and solid ash as in Example 7. Further, in the sample 23, the grain boundaries of the chromium nanoparticles covering the pellets of the sample 21 disappeared, and all the pellets were covered with the corrugated film having a thickness of about 300 nm formed of a continuous bulk of chromium. In Sample 24, the grain boundaries of the chromium nanoparticles covering the pellets of Sample 22 disappeared, and all the pellets were covered with an approximately 600 nm thick wavy film consisting of a continuous bulk of chromium.
As described above, as a result of heat-treating the helical internal gear 3 at 800° C. in the air atmosphere, the surface layer of the helical internal gear 3 was oxidized to chromium oxide, but the internal of the helical internal gear 3 was , The thermal decomposition proceeded with all the pellets covered with the chromium film, and was decomposed into a liquid substance and solid ash. Therefore, all the pellets constituting the helical internal gear 3 are shielded from the outside by the chromium coating, and the helical internal gear 3 has nonflammability and non-self-igniting properties. In addition, the collection of metal-bonded chromium nanoparticles that covered the helical internal gear 3 was heated up to 800° C. as a result of the growth of nanoparticles and coarsening of grain boundaries as the temperature increased. It is considered that the grain boundaries of the nanoparticle disappeared and changed to a coating consisting of a continuous bulk of chromium.
Therefore, in order to allow the helical internal gear to have non-combustibility at least at 800° C. and a property of not self-igniting, the pellets were formed with six layers of chromium nanoparticles in the same manner as in Examples 7 and 8. It has been found that a suspension that has been stacked and bound can be used as a raw material.
Further, in this embodiment, the helical internal gear having the non-combustibility and the property of not self-igniting was manufactured by the injection molding method, but the manufacturing of the helical internal gear is merely an example.

Therefore, the cylinder for filling the sample 5 or the sample 7 was preheated to 302° C., which is the boiling point of benzyldiglycol, and the die for extruding the sample 5 or sample 7 was preheated to 315° C. Next, the cylinder was filled with the sample 5 or the sample 7, the screw in the cylinder was applied with a pressure of 15 MPa and slowly rotated, and extruded as a hexagonal pipe 4 from the groove inside the die in front of the cylinder. ..
Next, a part of the extruded two kinds of hexagonal pipes 4 was cut out as a sample 25 or a sample 26, and the surface and the cut surface were observed with an electron microscope in the same manner as in Example 1. The surface of both hexagonal pipes 4, unlike the surface of sample 6 or sample 8, was covered with a cluster of coarse chromium nanoparticles with a size of 50-70 nm. The cross section of the sample 25 was different from the cross section of the sample 6, and the coarsened chromium nanoparticles were stacked and bonded with a thickness of about 5 layers to cover the pellet. The cross section of the sample 26 was different from the cross section of the sample 8 and the coarsened chromium nanoparticles were stacked and bonded with a thickness of about 10 layers to cover the pellet.
Two pieces of each of the two types of hexagonal pipes 4 were dropped from a height of 2 m, but only slight dents were formed, and the hexagonal pipes 4 were not broken. Therefore, it was found that the molded product in which the molding materials are bonded to each other by the aggregate of the chromium nanoparticles has a certain mechanical strength.
Further, two pieces of each of the two kinds of hexagonal pipes 4 were left for 5 minutes in the air atmosphere at 800° C. as in the case of Example 7, the molded products were taken out, and a part of the molded products was used as sample 27 and sample 28. It was cut out and the surface and the cut surface were observed with an electron microscope in the same manner as in Example 1. As in Example 9, the surfaces of both hexagonal pipes 4 were in a dark green smooth state and were composed of chromium oxide. In addition, as a result of observing the cross section of Sample 27 and the cross section of Sample 28 with an electron microscope, all pellets were decomposed into a black liquid substance and solid ash as in Example 7. Further, in Sample 27, the grain boundaries of the chromium nanoparticles covering the pellets of Sample 25 disappeared, and all the pellets were covered with a corrugated film having a thickness of about 300 nm and formed of a continuous bulk of chromium. Further, in the sample 28, the grain boundaries of the chromium nanoparticles covering the pellets of the sample 22 disappeared, and all the pellets were covered with the corrugated film having a thickness of about 600 nm formed of a continuous bulk of chromium.
As described above, as a result of heat-treating the hexagonal pipe 4 at 800° C. in the air atmosphere, as in Example 9, the surface layer of the hexagonal pipe 4 was oxidized to chromium oxide, but the inside of the hexagonal pipe 4 was Thermal decomposition proceeded in a state where the pellets of No. 1 were covered with a chromium film, and decomposed into a liquid substance and solid ash. Therefore, all the pellets forming the hexagonal pipe 4 are shielded from the outside by the chromium coating, and the hexagonal pipe 4 has nonflammability and non-self-ignition properties.
Therefore, in order to provide the hexagonal pipe 4 with nonflammability at least at 800° C. and a property of not self-igniting, as in Example 9, the pellets were formed by stacking six layers of chromium nanoparticles and stacking them together. It was found that the suspension may be used as a raw material.
In addition, in this embodiment, a hexagonal pipe having the properties of noncombustibility and non-self-ignition is manufactured by the injection molding method, but the production of the hexagonal pipe is merely an example. The shape of the groove that pushes out the suspension can be freely changed, and various shapes of non-combustible and self-igniting molded articles can be manufactured. Further, the molding material is not limited to the PES resin, and various molding materials made of other amorphous thermoplastic resin or crystalline thermoplastic resin can be used as described in the 37th paragraph of Example 3. .. Further, the metal nanoparticles binding the molding material are not limited to copper, and the metal octylate compound described in the 30th paragraph is used, whereby the molding material can be bonded by a collection of nanoparticles composed of various metals.
As described above, using the suspension in which the molding material is PES resin, a molded body was manufactured by the injection molding method in Example 9 and by the extrusion molding method in Example 10. As the molding material, not only the PES resin but also another amorphous thermoplastic resin can be used, and as explained in the 26th paragraph, the aggregate of pellets is heated to a temperature exceeding the glass transition temperature to soften the pellets.

Example 11
In this example, the sample 9 manufactured in Example 5 was used to manufacture the bottle 5 having a thickness of 0.3 mm illustrated in FIG. 5 by the air blow molding method.
Therefore, the cylinder of the extruder was preheated to 243° C., which is the boiling point of phenylpropylene glycol. In addition, the pair of molds sandwiching the suspension extruded into a tube shape was preheated to 255°C. The inside of the pair of molds has the shape of the outside of the container to be manufactured. Next, the cylinder was filled with the suspension, and a screw in the cylinder was applied with a pressure of 15 MPa to slowly rotate it. From the groove inside the die in front of the cylinder, the outer diameter was 1 cm and the wall thickness was Extruded as a 0.17 cm tube. After sandwiching this tube with a pair of molds and closing the molds, compressed air that increases the pressure to 20 MPa in 30 seconds is supplied to the inside of the tube by an air blow device, and the tube is attached to the pair of molds for 1 minute. Held After this, the supply of compressed air was stopped and the gas was sucked from the inflated tube. Further, compressed air of 40 MPa was sent to the inside of the swollen tube by an air blow device to pressurize the swollen tube. Then, the mold was opened and the bottle 5 was taken out.
Next, a part of the bottle 5 was cut out as a sample 29, and the surface and the cut surface were observed with an electron microscope as in Example 1. Unlike the sample 9, the surface of the bottle 5 was covered with a cluster of coarse copper nanoparticles having a size of 50 to 70 nm. The cross section of the sample 29 was different from the cross section of the sample 10, and the coarsened copper nanoparticles were stacked and bonded with a thickness of about 5 layers to cover the pellet.
Also, the two bottles 5 were dropped from a height of 2 m, but only slight dents were formed, and the bottle 5 was not broken. Therefore, it was found that the molded product in which the molding materials are bonded to each other by the aggregate of copper nanoparticles has a certain mechanical strength.
Further, the two bottles 5 were allowed to stand at 800° C. for 5 minutes in the air atmosphere in the same manner as in Example 7. The molded product was taken out, a part of the molded product was cut out as a sample 30, and the surface and the cut surface were observed with an electron microscope in the same manner as in Example 1. As in Example 7, the surface of the bottle 5 was in a dark red smooth state and was composed of cupric oxide CuO. In addition, as a result of observing the cross section of the sample 30 with an electron microscope, all the pellets were decomposed into a black liquid substance and a solid ash as in Example 7. Further, in the sample 30, the grain boundaries of the copper nanoparticles covering the pellets of the sample 29 disappeared, and the sample 30 was covered with a corrugated film having a thickness of about 300 nm and formed of a continuous bulk of copper.
As described above, as a result of heat-treating the bottle 5 at 800° C. in the air atmosphere, the surface layer of the bottle 5 was oxidized to cupric oxide, but inside the bottle 5, all the pellets were covered with a copper film. Pyrolysis proceeded in the broken state and was decomposed into a liquid substance and solid ash. Therefore, all the pellets constituting the bottle 5 are shielded from the outside by the copper coating, and the bottle 5 has the property of being nonflammable and not self-igniting. The collection of metal-bonded copper nanoparticles that covered the bottle 5 was heated to 800° C. as a result of nanoparticle growth and grain boundary coarsening as the temperature increased. It is probable that the grain boundaries disappeared and the coating became a continuous bulk copper film.
Further, in this embodiment, a bottle having a non-combustible property and a property of not self-igniting was produced by the air blow molding method, but the production of the bottle is only an example. Since the shape of the pair of molds sandwiching the extruded tube can be freely changed, it is possible to manufacture a hollow molded body having various shapes such as nonflammability and self-ignition. Further, the molding material is not limited to the PET resin, and as described in the 39th paragraph of Example 5, various molding materials composed of a thermosetting resin, an amorphous thermoplastic resin, or another crystalline thermoplastic resin. Can be used. In addition, the metal nanoparticles that bind the molding material are not limited to the copper nanoparticles, but by using the complex composed of the inorganic metal compound described in the paragraph 29, the molding material is bonded to a group of nanoparticles composed of various metals.

Example 12
In this example, the sample 11 manufactured in Example 6 was used to manufacture the container 6 having a thickness of 1 mm illustrated in FIG. 6 by the thermoforming molding method. Therefore, the cylinder of the extruder is preheated to 329° C., which is the boiling point of tetraethylene glycol. In addition, a pair of molds sandwiching the sheet-shaped extruded suspension was preheated to 340°C. The lower mold of the pair of molds has the shape of the outer diameter of the container 6, and a part of the lower part is connected to the suction hose of the vacuum pump. The upper mold of the pair of molds has the shape of the inner diameter of the container 6. Next, the cylinder was filled with the sample 11, and the screw in the cylinder was slowly rotated by applying a pressure of 15 MPa, and the width was 3.1 cm and the thickness was 0 from the groove inside the die in front of the cylinder. It was extruded as a 0.6 mm sheet. Further, the sheet was sandwiched between a pair of molds. Then, the vacuum pump is operated to lower the upper mold to a distance of 0.5 mm with respect to the lower mold, and the pressing force for increasing the pressing force to 20 MPa in 30 seconds is applied to the sheet by the upper mold. And left for 1 minute. After this, the pressurization of the upper mold was stopped. Further, a pressure of 30 MPa was applied by the upper mold. Then, the upper mold was pulled up and the container 6 in the lower mold was taken out.
Next, a part of the container 6 was cut out as a sample 31, and the surface and the cut surface were observed with an electron microscope as in Example 1. Unlike the sample 11, the surface of the container 6 was covered with a cluster of coarse particles of chromium having a size of 50 to 70 nm. The cross section of the sample 31 was different from the cross section of the sample 11 and the coarsened chromium nanoparticles were stacked and bonded with a thickness of about 5 layers to cover the pellet.
Further, the two containers 6 were dropped from a height of 2 m, but only slight dents were formed and the containers 6 were not broken. Therefore, it was found that the molded product in which the molding materials are bonded to each other by the aggregate of the chromium nanoparticles has a certain mechanical strength.
Further, the two containers 6 were left at 800° C. for 5 minutes in the air atmosphere in the same manner as in Example 7. After that, a part of the container 6 was cut out as a sample 32, and the surface and the cut surface were observed with an electron microscope as in Example 1. As in Example 9, the surface of the container 6 was in a smooth state of dark green and was composed of chromium oxide Cr ₂ O ₃ . Further, as a result of observing the cross section of the sample 32 with an electron microscope, all the pellets were decomposed into a black liquid substance and a solid ash as in Example 7. Further, in Sample 32, the grain boundary of the chromium nanoparticles covering the pellet of Sample 31 disappeared, and the sample 32 was covered with a corrugated film having a thickness of about 300 nm and formed of a continuous bulk of chromium.
As described above, as a result of heat-treating the container 6 at 800° C. in the air atmosphere, the surface layer of the container 6 was oxidized to chromium oxide, but inside the container 6, all the pellets were covered with the chromium film. In the state, thermal decomposition proceeded and was decomposed into a liquid substance and solid ash. Therefore, all the pellets constituting the container 6 are shielded from the outside by the chromium coating, and the container 6 has the property of being nonflammable and not self-igniting. In addition, the collection of metal-bonded chromium nanoparticles that covered the container 6 was heated up to 800° C. as a result of the growth of the nanoparticles and coarsening of the grain boundaries as the temperature increased. The grain boundaries disappeared, and the coating changed to a continuous bulk of chromium.
In this embodiment, a container having nonflammability and non-self-igniting properties was manufactured by the thermoforming molding method, but the manufacturing of the container is merely an example. Since the shape of the pair of molds sandwiching the extruded tube can be freely changed, it is possible to manufacture a hollow molded body having various shapes such as nonflammability and self-ignition. Further, the molding material is not limited to the PAF resin, and as described in the 40th paragraph of Example 6, an amorphous thermoplastic resin having a higher glass transition temperature with respect to the thermal decomposition temperature of the metal octylate compound. Alternatively, a crystalline thermoplastic resin having a higher melting point can be used as a molding material. In addition, the metal nanoparticles that bind the molding material are not limited to the chromium nanoparticles, but by using the metal octylate compound described in paragraph 30, the molding material can be bound by a collection of nanoparticles composed of various metals. You can

That is, the complex composed of the inorganic metal compound described in paragraph 29 or the carboxylic acid metal compound described in paragraph 30 is dispersed in alcohol, and the alcohol dispersion has a boiling point higher than the thermal decomposition temperature of the complex or the metal carboxylic acid compound. A high organic compound is selected from the organic compounds described in the paragraphs 32-34 and mixed, and the mixture is added with a softening point, a glass transition temperature or a melting point depending on the thermal decomposition temperature of the complex or the metal carboxylate compound. When a molding material composed of the synthetic resin is selected from the molding materials of the synthetic resin described in paragraphs 25-27 and mixed, and the mixture is heat-treated to thermally decompose the complex or the metal octylate compound, the metal of various materials is mixed. A suspension in which a molding material made of various materials and covered with a collection of nanoparticles is dispersed in an organic compound is produced. Therefore, the suspensions described in Examples 1-6 are merely examples of suspensions.
Furthermore, if the viscosity of the organic compound that constitutes the suspension and the mixing ratio of the organic compound in the suspension are changed, and if the mixing ratio of the molding material in the suspension is changed, the suspension is used when producing a molded body. The slipperiness and tenacity of the can be freely changed. Therefore, there is no restriction on the type of molding machine and the shape of the mold used when processing the molded body using the suspension as the raw material. Therefore, the molding method and the shape of the molded body described in Examples 7-12 are merely examples.
As described above, according to the present invention, a group of metal nanoparticles composed of various metals shields the molding material from the outside world, and a molding body in which the molding material is bonded by metal bonding of the metal nanoparticles has various shapes. It can be manufactured as a molded body of various shapes according to various molding methods. This molded product is an epoch-making molded product in which no vacuoles are formed inside, and which is nonflammable and does not self-ignite.
Furthermore, since all of the molding materials that form the molded body are covered with a group of metal-bonded metal nanoparticles, the molded body that is lighter than the metal has the heat resistance of the metal and the properties of the metal. This opens up new functional applications for the conventional synthetic resin moldings. For example, according to the molding method, a molded body such as a shield substrate that reflects electromagnetic waves, a heat radiation substrate that releases heat, and an antistatic substrate that does not charge static electricity can be manufactured.
