[Technical field to which the invention belongs] The present invention relates to a type of heat absorption. Products with excellent properties are particularly related to a metal and non-metal casing with a heat-generating component, such as a motor, an electronic component, a heater, and a battery, and a surface-treated metal plate as a material of the casing.

Portable devices or in-vehicle devices include mobile phones, notebook personal computers, PDAs, car battery cases, air car navigation systems, car audio devices, and car control devices. I: Prior art J Background technology 15 The main materials used for the outer shell and inner parts of home appliances are steel plates. Lvban and other metal plates, and this type of metal plate is required to have properties such as flexibility and design, so it is generally used after surface treatment. Examples of such metal plates include mineral steel plates with excellent corrosion resistance, mineral zinc steel plates covered with gallate, and pre-coated metal 20 plates that are pre-coated for design. In addition, these metal plates are further inflamed and have ancient fingerprints with resistance to fingerprints, grounding, and abrasion during processing. In order to meet these performances, various surface-treated steel plates have been developed. For example, Japanese Patent Publication Gazette No. 4_ΐ4ι9ι discloses 66. The description of the invention shows that it is formed on a water-based organic resin by adding a colloidal sol with a specific fine particle size to an aqueous organic resin.

In addition, Japanese Patent Application Laid-Open No. 5_65666 discloses a technique for improving the work wear resistance by applying a coating containing soil and a lubricant to an electroplated steel sheet. In addition, Japanese Patent Application Laid-Open No. 16128 discloses a technique for covering fingerprint-resistant and grounding properties of a metal surface treated with a salt solution by covering a thin film having a controlled surface roughness and film thickness. Furthermore, non-gold materials such as plastics are also used as the outer material of the outer plates and internal parts of household appliances. This kind of misfortune is also due to the popularity of computers and the electronics of home appliances in recent years. Internally, the multi-motor and electronic parts # have become parts of heat sources, and the heat generation of these heat sources has gradually increased. Therefore, the outer materials of the products and the shell materials of the internal parts also require that they have Characteristics' or characteristics which can efficiently dissipate this heat. On the other hand, it is also required that the housing of the heating element such as household appliances must have conductivity for grounding. In the past, in order to suppress the internal temperature rise of electronic equipment with built-in electronic components, heat dissipation was installed in the electronic components in consideration of heat dissipation. Film, and openings for heat dissipation in the housing of electronic equipment. Electronic equipment is not heat-resistant, and a and 硓 will be reduced in performance. Therefore, it is important to reduce the heat dissipation and cooling when temperature rises to cause malfunctions. Recently, because of the high temperature, it is possible to cope with the temperature rise by 200404673, and it is more important to take measures to reduce the performance, such as slow speed. "The portable machine (mobile machine) of the sub machine Yi and the on-board machine named J and exposed to heat from the engine etc., the built-in parts and the self-heating of the M will be in the machine case" Increasing the temperature of equipment and batteries is a very important issue. In the past, the main technology used in coatings' for the heat dissipation of the housing of electronic equipment was to form a high-heat vent or a case with a high heat-transmitting material. It has been proposed to coat the outer side of the casing with high radioactivity to improve heat dissipation.

A known technique similar to the present invention is disclosed in Japanese Patent Laid-Open Publication No. Hei-340639: the inner surface side of a casing of an electronic device including a τν receiver and other portable information devices is coated with infrared absorption Agent coating film. 15 ^ For the cooling and heat dissipation of electronic equipment, it has been proposed or adopted as before

The various methods described above, however, in portable devices or vehicle-mounted devices, the material of the casing is often restricted due to reasons such as beauty and lightness, and in order to reduce size and performance, more efficient cooling is required. , Heat dissipation.

The third object of the present invention is to provide a casing with improved heat dissipation in a portable device or a vehicle-mounted device with built-in heat-generating electronic parts, and to provide a portable device or a vehicle-mounted device having such a case. [Inside the invention] Disclosure of the invention The present inventor devoted himself to reviewing the conventional technology.

Brief Description of the Drawings Fig. 1 is a view showing the structure of a heat-generating body casing or case having excellent heat absorption properties according to the present invention. FIG. 2 is a view showing a state of a measuring box for measuring heat absorption. Embodiments of the present invention (metal and non-metal heating element housings and surface-treated metal plates) In the present invention, the heating element may be All parts that generate heat, such as motors, electronic parts, heaters, batteries, etc., are not particularly limited. The heating element casing is used for the purpose of covering, surrounding, and accommodating such a heating element. In the following, the heat-absorptive heating element casing of the present invention is mainly used to explain the gold 14 200404673. The invention description is a plate-made heating element casing, but the present invention is not limited to this, and is equally applicable to non-metallic heating element casings. . The thermal system is part of the electromagnetic wave emitted by the object. Once the thermal radiation is incident on the object, a part of it is reflected, a part of it is transmitted, and the remaining 5 points are absorbed (for example, by Nishikawa and Fujita, " Basic Lectures on Mechanical Engineering, Electrical Engineering ", P.289, Publishing House: Institute of Science and Technology (1983)). When heat radiation is incident on a metal plate, a surface-treated metal plate, or a non-metallic material, since the heat radiation is hardly transmitted, the heat radiation becomes one of reflection or absorption. 10 Here, when the heat radiation generated by the heating element is incident on the inner surface of the heating element casing, once most of the incident thermal radiation is reflected, the heat will be trapped inside the heating element casing, and the temperature inside the casing will rise. Therefore, in order to reduce the temperature in the heat source housing, it is necessary to suppress the reflection of thermal radiation inside the housing. The present inventor devoted his research, and found that by covering the inside of the housing with a thin film layer having high heat absorption, the heat can be suppressed. Radiation reflection. A well-known method for measuring the absorptivity of thermal radiation incident on the surface of a metal plate, a non-metallic material, or the like is a reflection method using an infrared spectrophotometer. However, when measuring by this method, if a metal plate or 20 #The thickness of the surface of the metal material is too rough, and the incoming heat radiation will be reflected, so it is difficult to obtain a high-accuracy absorption rate. According to Kirchhoff's Law on Thermal Emission ', at a certain temperature, the absorption and emissivity of an object are the same ("Mechanical Fundamentals of Trencher Electric Heating Engineering" by Nishikawa and Fujita, "ρ 290, issued by Institute of Science and Technology (1983) 15 200404673 发明, description of the invention The inventor committed to review based on this law, and found that if at least one side of a metal plate or an electroplated metal plate is previously covered with a heat-absorbing film layer, The shell made of the surface-treated metal sheet is formed to cover 5 heating elements, wherein the heat-absorbing film layer is 80. (: in a region with a wave number of 600 to 3,000 cnT1 measured at a temperature of 200 ° C or more and below, the total When the emissivity is greater than or equal to 70.70 ', the temperature inside the case will be lower than when the case is covered with a heat generator made of a metal plate that is not covered with a heat-absorbing film on the inner surface of the case. Similarly, it has been found that The inner surface of the case made of non-metallic material is covered with a heating element with a heat-absorbing film layer of 10 and the heat-absorbing film layer, wherein the heat-absorbing film layer is at 80 C or more and 200. (: measured at a temperature below In the area of 600 ~ 3000CHT1, the total emissivity is 0.70 or more, compared with when the outer cover is covered with a heat absorbing film and the outer surface of the outer cover is covered with a heating element, the temperature inside the outer cover is lowered. 15 20

Since the radiation absorption in a wave number region with a frequency of less than 600 cm-1 or greater than 3000 cm-! Has a very small effect in reducing the temperature inside the housing, the emissivity of radiation including those wave number regions is not appropriate. Further, it is not suitable to cover the area with a wave number of 600 to 300 W1 with an absorptive thin film layer having a total emissivity of less than 0.70, which has a small effect of lowering the temperature in the case. Fig. 1 shows the structure of a metallic or non-metallic heating element case having excellent heat absorption properties according to the present invention. This hair θI is only a garment or a non-metallic heating element. The outer shell is composed of a metal plate or a non-metallic weight M material 1 and the inner surface is covered with a heat-absorbing film layer 2. In addition, 3 in the figure is a heating body. If the heat-absorbing film layer 2 is covered with a flat metal plate or a non-metal material in advance with 16 200404673 玖, the description of the invention, and processed into a metal or non-metal heating element casing, the manufacturing efficiency can be improved. , So very suitable. In addition, if the inner surface of the heating element casing is not composed of a metal plate or a non-metallic material covered with a heat-absorbing thin film layer, the effect of reducing the degree of heat generation outside / V and inside / jnL cannot be obtained. The heat-absorbing film layer can cover not only the inner surface of the heat-generating body casing, but also the outer surface. When it is also covered on the outside, the temperature of the metal or non-metal heating element case itself is lowered due to the influence of heat radiation equivalent to heat absorption, so it is more suitable. In order to ensure the heat absorption of the metal plates and non-metal materials used to constitute the metallic and non-metallic heating element casings having excellent heat absorption properties of the present invention, Or one side of the non-metallic material is covered with a heat-absorptive film layer, and the heat-absorptive film layer is composed of a) 100 parts by mass of the binder solid content, and b) 15 ~ 15G parts by mass of the heat-absorbent pigment. Composition, and the wave number measured at a temperature below thief and above c in a range of ˜3G () (wl, the total emissivity is 0.70 or more. Heat-absorbing pigments can be generally known as carbon, carbon, graphite, etc. Alternatively, a commercially available one can be used. Among the aforementioned heat-absorbing pigments, carbon black has a particle size of J and can be widely dispersed in thin films, so it is a preferred pigment, and especially a particle size of 1 to 100 nm. The inventors have further discovered that the total emissivity of the thin film layer covered with a metal plate or non-metallic material can be increased, and carbon that is used to increase heat absorption in the thin film layer can be used to shield the metal plate or Non-metallic materials 17 Explanatory materials. In addition, here, the so-called carbon can be carbon black, carbon, graphite and other common spoons. In order to shield metal plates or non-metallic materials with stones, it is necessary to add carbon with a smaller particle size. A small amount of carbon with a small particle size has a small shielding effect, and as for a large particle size of carbon, even if a large amount is added, there is a small shielding effect because there is a gap between carbon and 5 carbon. However, when a large amount of particle size is added When the carbon content is small, the viscosity of the coating liquid containing the solid component of the binder and the carbon increases, which reduces the coating workability. The fine particles dispersed in the coating liquid will agglomerate after a period of time to make the coating liquid Problems such as gelatinization, etc. In order to solve these problems, the present inventors worked hard and found that, by using 0, a small particle size having a particle size of less than 0 1 // m and a particle size of not less than 0 and not more than ^ Particle size carbon can solve the aforementioned problem. Because by using these carbons in combination, fine-grained carbon will be dispersed in the gaps between the large particle size carbon dispersed in the film, so even if a large amount of fine carbon is not added, the shielding metal of the carbon can still be improved. Plates and non-metallic materials And the effect of heat absorption. ^ In the preferred embodiment of the present invention obtained by ° Hyme, the addition of carbon added to the heat absorbing film layer (hereinafter referred to as the heat absorbing film) The amount is based on 100 parts by mass of the solid content of the binder, and contains 1 to 2 parts by mass of carbon having a particle size smaller than that of carbon and particle size of pugang by 0% or less, and the particle size is less than 〇ι. The total amount of the fine particle-based charcoal and the large particle size carbon with a particle size of 0 2 Å to 50 / Zm is 10 to 150 parts by mass, and the film thickness of the hot fruit layer is "claw or more." The lower limit of the particle size of carbon is also stipulated. However, if it is exceeded, it is easy to form an interstitial spring between carbon and carbon, and cannot function as a fine particle charcoal. If it is less than i parts by mass, the metal plate or non-18 200404673 玖, the invention explains that the metal material has poor shielding effect and poor heat absorption, so it is not suitable. If it is more than 20 parts by mass, the viscosity of the coating solution will become high. , And becomes gelatinous after a period of time, so it is not suitableIf the particle size of the large particle size carbon is less than 0.1 / z m ′, it will not function as a large particle size carbon, and will exhibit the same characteristics as the fine particle carbon, so it is not suitable. If the particle diameter of the large-diameter carbon is larger than 50 # m, when the coating liquid containing the large-diameter carbon is applied, the applicability will be reduced, and the appearance of the film after coating is poor, so it is not suitable. The particle diameter of the large-diameter carbon is preferably from 0.1 / zm to 30 / zm. Among them, the ratio is more preferably 0 1 // m to 10 10 / zm. If the amount of large particle size carbon added is less than 丨 parts by mass, the heat absorptivity will be poor. If it is larger than 14 parts by mass, the film will become fragile and the film will have poor processability, so it is not suitable. Furthermore, if the total addition amount of fine particle carbon and large particle size carbon is less than 10 parts by mass, the heat absorption is poor, and if it is greater than 150 parts per part, the film becomes weak, and the film has poor processability.

15 'The thickening of the coating liquid makes the coating workability poor, so it is not suitable "and if the film thickness of the thermal film is less than 1 / zm, it is not suitable because it has poor heat absorption. It is not suitable for constituting the invention with excellent heat absorption. In order to ensure the heat absorption and conductivity of metal plates and non-metal materials of metal and non-metal heating element housings

It can be achieved through the metal plate of electricity money, or non-present metal materials. The early surface of the material is covered with a heat-absorbing layer, and the heat-absorbing film layer is composed of a) ⑽ mass parts of the binding agent. Solid content, b) 10 to 150 parts by mass of heat-absorbing pigment, in addition to e) 1 part by mass of conductive pigment, and measured at a temperature of 200 ° C below 200 C 'Total emissivity of 0.70 or more in the region of 60 to 3_⑽-]. 19 20 200404673 (ii) Description of the invention As the conductive pigment, known ones are flaky metal Ni, chain metal Ni, granular metal A, flaky metal A1, and stainless steel powder, and commercially available ones. However, metals generally tend to reflect heat and tend to hinder the heat absorption of heat-absorbing pigments. Compared with other metal pigments, metal Ni is less likely to hinder the heat absorption of heat-absorbing pigments, and because the chain-shaped metal Ni is chain-shaped, the area for reflecting heat in the film is small, so it is not easy to hinder heat absorption. suitable. However, since only the chain metal Ni has poor electrical conductivity, it is preferable to use a combination of the sheet metal Ni and the chain metal Ni. At this time, if the mass ratio of the flaky gold 10 to Ni / chain metal Ni is 0 to 6 because both the heat absorption property and the electrical conductivity are excellent, it is more suitable. The flaky metal Ni has a large area for reflecting heat in the thin film, and therefore it is easy to prevent heat absorption. Therefore, if the mass ratio of the sheet metal Ni / chain metal milk is less than 0.1, the electric property is poor. On the other hand, if it is greater than 6, the heat absorption is poor 15 〇

Furthermore, if the aforementioned conductive pigment is ferrosilicon, the emissivity of the heat-absorbing film layer can be improved, and survivability can be improved when the metal plate is surface-treated, so it is more suitable. Because Shixi Iron is not only excellent in electrical conductivity, but also excellent in heat absorption, it can be used as both a conductive pigment and a heat-absorbing pigment. Therefore, even if added separately, the two characteristics of thermal readability and conductivity can be ensured. Due to the fact that the content of the heat-absorbing pigment is less than 10 parts by mass relative to 100 parts by mass of the binder solid content, the wave number is measured at a temperature of 8 (rc or higher. C below a certain temperature _ ~ 300 (W) In the area, the total emissivity of the metal plate is less than 0.70, so it is not suitable. 20 200404673 发明, description of the invention The emissivity will increase as the amount of heat-absorbing pigment added to 100 parts by mass of the resin solid content, It is more suitable, however, if it is more than 15 parts by mass, the film layer becomes weak, and the impact resistance of the film layer is reduced. Therefore, the workability during processing of a metal plate is reduced, which is not suitable. 5 Heat-absorbing film Although the film thickness of the layer can be arbitrarily selected according to the needs, it should be 1 ~ 50 // m if it is a metal plate, and 1 ~ 1000 // m if it is a non-metal material. If it is less than 1 # m, It is difficult to make the total emissivity of a metal plate or non-metallic material to be above 0.70 in a region with a wavenumber of 600 to 3000 cm-1 at a temperature of 80 ° C to 200 ° C. 10 is greater than 50 # m, because the processability of the film layer will be reduced, It is unsuitable. When it is a non-metallic material, if it is greater than 1000 / m, it is not suitable because the heat absorption is saturated and it is not economical. Also, if conductivity is considered, it is greater than or equal to 1 // m and It is more preferably less than 10. The binder used to constitute the heat-absorbing film layer of the present invention can be formed by using a resin 15 and an inorganic thin film formed by the sol-gel method (sol-gel). Inorganic and organic composite films are generally known as binders for films. The use of resins in the form of coatings is very suitable because of the ease of handling and film formation methods. For the resins, generally known ones such as polyester resins and amines can be used. Ethyl formate, acrylic resin, epoxy resin, melamine resin, ethyl acetate, etc., and can be any of thermoplastic and thermosetting types. These resins can also be used in combination as needed These resins also differ in film properties such as processability, processing adhesion, and film hardness due to the type, molecular weight of the resin, and glass transition temperature Tg of the resin. 21 The type of resin that is hardened by the bridging agent is also due to the type and amount of catalyst used in the bridging agent breeder's spear 4, Gary, and bridging reaction. Processability, processing adhesion, film hardness, etc. are different and / or there are special regulations, which must be appropriately selected according to the needs. Those who are known as solids can be melted by heat and dissolved in organic solvents to make the meal crushed. It can be used as a powder. In addition, it can be a water-soluble resin and a water jet resin type resin. Furthermore, it can be an ultraviolet () hardening spear electron beam (EB) hardening resin. All of these resins can be used Commercially available type 10. According to the present inventors' findings so far, solvent-based trimeramine solid-type n-based, solvent-based isocyanate-solid polyacetate-based, water-dispersible acrylic emulsion, and the like are preferred. , Especially the following. However, these resins are only examples and are not limited thereto. 15 If it is a solvent-based melamine solid polyester, the average molecular weight of the polyester resin is preferably 2000 to 30,000, the Tg of the polyester resin is preferably 10 to 70 ° C, and the relative amount of melamine resin is relative. The polyester resin in an amount of 100 parts by mass is preferably 5 to 70 parts by mass. If the molecular weight of the polyester resin is less than 2000, the processability of the film will be lowered by -0, and the right will be greater than 30,000, because the viscosity of the resin when dissolved in a solvent is too high, so it is not suitable. If the Tg of the polyester resin is less than 10 ° C, it is not suitable because the film will not form a film. If it is higher than 70 ° C, the film is too hard, so the processability is reduced, which is not suitable. If the added amount of melamine resin is less than 5 parts by mass of polyester resin, the film is not hardened, so it is not 22 200404673 玖, the description of the invention is suitable, if it is more than 70 parts by mass, because the film becomes too hard, so that It is not suitable because the workability is reduced. The polyester resin used can be used by general marketers, such as "Bylon (5 Vylon, 7, Horiguchi ^)" manufactured by Toyobo Co. Ltd. (Toyobo Co., Ltd.) "Sumikabashi "Desmophen (工 &gt;)" manufactured by Sumika Bayer Urethane Co. Ltd .; Sumika Hachiman Kosho Ltd .; The melamine resin used can also be used by general marketers, such as R. Sémel (10 Psymel; Inch &gt;) made by Matsui Psytec Co. Ltd .; ) "," Mycoat (MyCOat;) Yibu "," Bekamine "manufactured by Dainippon Ink Chemicals Inc. (Dainippon Chemical Industry Co., Ltd.)," SuperBekamine )"Wait. In the case of solvent-based isocyanate-solid polyester, the average molecular weight of 15 molecular weight polyester resin should be 2000 ~ 30,000, the Tg of polyester resin should be 10 ~ 70 ° c, and the addition amount of isocyanate resin should be [NCO group equivalent of isocyanate] / [OH group equivalent of polyester resin] = 0.8 to 1.2 is preferred. If the value of [NCO group equivalent of isocyanate] / [0H group equivalent of polyester resin 20] is less than 0.8 or more than 1.2, the film tends to become unhardened when a film is produced. If the molecular weight of the polyacetate resin is less than 2000, the processability of the film is reduced, and if it is more than 30,000, the viscosity of the resin when dissolved in a solvent is too high, so it is not suitable. If the τ g of the polyg resin is less than -10 ° C, it is not suitable because the film will not form a film. If it is greater than 70 ° C, the film will be too hard, so the workability will be reduced. Not appropriate. The polyester resins used can be found by general marketers, such as "Bylon" manufactured by Toyobo Seima Co., and "Desmolen" manufactured by Sumika Bayer Polyurethane Co., Ltd. 5 The isocyanate used can also be used by general marketers, such as "Similar (Sumidur; only S ^ 21%)) manufactured by Sumika Bayer, Dai :, Kor (DeSmodur; 々 十 ~) One outside "," Takeda Chemicals. Lnc .; Takei; Mitsui Takeda; "Kake" made by Takenate; 1 "" F, water-dispersed The acrylic emulsion-type resin may be a generally known one or a commercially available one. The water-dispersible acrylic emulsion resin can also be used by adding a resin having good adhesion such as epoxy resin. Because the type and addition amount of the mounting oxygen resin will affect the performance of the coating film, ^ can be appropriately selected according to needs. For water-based resins such as water-dispersed acrylic acid resins, the coating workability of the film is high, and there is no problem with the emission of military hair. Organic matter, cereals and air, so no exhaust is needed in the coating equipment. &amp; intensifying and volatile organic solvent combustion equipment, etc., are more suitable for the heat-absorbing film layer of the present invention. In addition to heat-absorbing pigments and conductive pigments, color pigments and Rust pigment and anti-iron agent. Titanium oxide (Ti〇2), zinc oxide (Zn〇), oxide (zr〇2), carbon hafnium (CaC〇3), barium sulfate, hafnium oxide (ai2 03), kaolin clay, Carbon black, iron oxide (Fe2Q3, F ... 24 200404673 玖, description of the invention) and other inorganic pigments, and organic pigments and other well-known colored pigments. As the rust preventive pigment, generally known chromium-based rust preventive pigments such as strontium chromate and calcium chromate, and zinc phosphate, zinc phosphite, aluminum phosphate, aluminum phosphite, molybdate, molybdate phosphate, and vanadate can be used. / Phosphoric acid mixed pigments, silicon oxide, and Ca-type silicon oxide, which are called calcium silicates, are generally known non-chromic antirust pigments and rust inhibitors. Especially when the base material of the metal plate of the present invention, such as a steel plate or an electroplated steel plate, is a corrosive metal, it is more suitable because the property of the metal plate of the present invention can be improved by adding an anti-rust pigment and an anti-rust agent. 10 In consideration of environmental issues in recent years, non-chrome antirust pigments and antirust agents are more effective. These non-chrome-based rust preventive pigments and rust preventives can be used with reagents or commercially available ones. Commercially available anti-rust pigments include zinc phosphate-based anti-rust pigments "EXPERT-NP500 15" and "EXPERT-NP530" manufactured by Toho Coloring Inc.

Since the coloring pigments, rust-preventive pigments, and rust-preventive agents vary in type, addition amount, and particle size, the emissivity and processability, appearance, and recording resistance of the other films are very different, so they must be appropriately adapted to the needs. Alas. Eight

In addition, the heat-absorbing film layer of the present invention can be added as needed-generally known dyeing agents, pigment dispersants, creep, and the like. The type and amount of these additives are not particularly specified, and can be appropriately selected according to needs. In particular, it is effective in improving the formability 10 when forming the surface-treated metal sheet of the present invention, and preventing damage to the heat-absorbing film layer.

In order to form the heat-absorbing film layer of the present invention on the surface of a metal plate or a surface of a non-metallic material, a film component containing a binder may be applied in a generally known coating form. For example, coatings include solvent-based coatings in which the resin is dissolved in a solvent, such as water-based 15 coatings in which emulsion resin is dispersed in water, powder coatings in which resin is pulverized and powdered, and resins in which pulverization and powder are dispersed Slurry powder coatings in water, ultraviolet (UV) hardening coatings, electron beam (EB) hardening coatings, film laminates in which resins are pasted into a film, and resins that are melted before being applied. Regardless of the above, the coating method is not particularly limited, and a generally known coating method such as roll coating, roller curtain coating, curtain spray coating, air spray, airless spray, brush coating, Die coating, etc. In addition, dip coating and inkjet coating may be used. In addition, before the metal plate is covered with the heat-absorbing film layer, in order to improve the film adhesion of the metal plate, it is suitable to pre-process the metal plate. If 26 ° C is carried out and the invention is described, the pretreatment can improve the adhesion of the heat-absorbing film and the resistance of the metal plate, which is more suitable. Since the coating film can be closely adhered even if the pre-coating treatment is not performed, the pre-coating treatment can be omitted, which is more suitable. For the pre-coating treatment, a generally known one can be used, for example, a chromate coating treatment, an electrolytic complex salt treatment, a Wei zinc treatment, an oxide material, a treatment, and a titanium oxide-based treatment. In addition, in recent years, non-chromium pretreatments based on organic compounds such as fat renewal have been developed. If resin-based non-chromate pretreatment is used, it can reduce the load on the environment, so More suitable. 10

Non-chromate pretreatments based on organic compounds such as resins can be performed, for example, in Japanese Patent Laid-Open Publication Nos. G9_828291, JP-A No. 10 251, JP-A No. 10-33753, and JP-A No. 2000. The techniques disclosed in 15 of _17466, relative opening 2000-th 85, JP 2__273659, JP 282252, JP 2__265282, JP 2__167, etc. can be used in addition to the aforementioned techniques. Other known techniques can be used.

It can also be treated with non-chromates already sold. Due to the difference in the type and amount of these pretreatments, the density of the heat-absorbing film layer and the resistance of the raw spear metal plate to the insects are very different, so they must be selected as appropriate. Tian Youfang, the purpose of the metal plate of the present invention is to process to make a metal heating shell, so as long as it can be processed metal material, ordinary A-head beneficial materials can be used. The metal material may also be an alloy material. Examples include steel, aluminum, titanium, copper, and magnesium alloys. In particular, if a metal with high thermal conductivity, such as aluminum and copper, is used, since the heat absorbed will be evenly dispersed in the metal, it is very suitable to avoid local heating of the metal. In addition, the surface of these materials may also be used by power miners. Examples of the type of electroplating include zinc plating, aluminum plating, copper plating, and nickel plating. Also alloys of money. In the case of steel plates, generally known steel plates such as cold-rolled steel plates, hot-rolled steel plates, hot-dip zinc steel plates, electro-galvanized steel plates, hot-dip galvanized steel plates, aluminized steel plates, aluminum-zinc alloyed electrical steel plates, and stainless steel plates can be used. Steel and galvanized steel. However, such as hot-dip galvanized steel sheet, iron and zinc bell steel sheet, because of its high heat absorption, it is very suitable to increase the heat absorption by covering it with a heat absorbing film. In addition, if a heat-absorbing film is coated on a steel plate coated with aluminum and copper with a specific thermal conductivity, the absorbed heat will be uniformly dispersed through the electroplated layer on the metal surface, which can avoid local heating of the metal, which is more suitable. These steel plates coated with metals with high thermal conductivity such as aluminum and copper can not only improve the thermal conductivity, but also possess the strength and formability of steel plates, and they are more effective than metals with high thermal conductivity such as aluminum and copper. Since it is cheap, it is more suitable to reduce the manufacturing cost. These metal plates can be treated with hot water, alkaline degreasing, pickling and other general treatments before pre-coating. A conventionally known processing method can be used when the metal is formed into a metal heating element case. Examples of the processing methods include forging processing, casting processing, punching processing, bending processing, extension processing, expansion processing, and roll forming. In addition, a pre-coating method in which a heat-absorptive thin film layer is previously coated on a metal plate and then formed is more suitable because of its high manufacturing efficiency. 5 10 15 20 发明 Description of the invention Non-metal materials used in this Maoming are all inorganic materials and organic materials except metal materials, except for plastics, resins, ceramics, pottery, water, corpses, etc., and they can also be natural material. In addition, among the resins, generally known resins such as acid resins, gas-based resins, HIPS-based resins, na-based resins, and carbonic acid-based resins can be used. In addition, as for the pottery, generally known pottery such as an oxidative inscription system, a pore-forming inscription system, a barium titanate system, and a cinnamic acid system can be used. In addition, if it is a non-metallic material, the surface of the non-metallic material to be covered with the heat-absorbing film may be subjected to a generally known chemical conversion treatment according to the needs: such as thicker chain degree, etc., to make the heat-absorbing film tightly contact Sexual improvement. Examples of the use of the heat-generating casing and the material of the heat-absorbing body of the product of the present invention include audiovisual equipment such as VTR, audio equipment, dvd, television, liquid crystal television, electric display tuner, personal computer, Personal computer peripherals such as notebook personal computers, optical disk drives, hard disk drives, mobile devices such as mobile phones, electronic notebooks, refrigerators, air-conditioners, outdoor units, air-conditioning indoor units, washing machines, and lighting appliances : Battery case, car battery case, car electronic parts equipment, car guide system, car audio equipment, vending machine, coin machine, prepaid card and ticket vending machine, etc. The use of the present invention, such as the housings, internal parts boards, internal and external electronic parts housings, and internal and external control machines of these machines, will be effective. In the following, a refrigerator, a portable device, and a vehicle-mounted device using the product of the present invention which has excellent heat absorption properties and its materials, and the present inventors have read and recognized the effects thereof are described in detail.

(Refrigerator 29 200404673 发明, invention description The use of a large number of motors and electronic parts inside the refrigerator as a heat source. In particular, in recent years, the electronicization of refrigerators has continued to develop 'from the heat generated by these two sources = stored in the refrigerator To make the internal temperature rise easily. To increase the temperature inside the refrigerator, in order to lower the temperature in the refrigerating compartment, 5 * more power is needed 'and the life of the motor and electronic parts is also shorter. However, in recent years, from the ecology From the viewpoint of consideration, the requirements for reducing the power consumption of electrical products such as refrigerators have gradually increased. The present inventors committed to review, and found that if a material with high heat absorption on the surface of a metal material is added to the inside of the refrigerator outer panel, Compared with the case where 10 heat-absorbing materials are added, the temperature near the heat source such as the motor will be lowered. The previous description of the heating element casing and the heat-absorbing film explained that if the outer panel of the refrigerator is constituted as a heating element The outer shell is directly applicable to the heat-absorptive film 15 covering the outer plate and the inner surface of the refrigerator of the present invention. Therefore, the refrigerator of the present invention may have the same structure and interior as those known except that the inner surface of the outer panel is covered with a specific heat absorbing film. The outer side of the outer panel of the refrigerator of the present invention If it is covered with a colored coating film and a transparent coating film, it is more suitable because it can impart a design appearance. The colored coating film layer 20 and the transparent coating film layer can be multi-layered, and the lowermost layer is used as an anti-rust coating containing an anti-rust pigment. The film layer, whereby the upper layer is used as a coloring layer containing a coloring pigment, and if necessary, a transparent film is covered thereon, etc., because it can improve the corrosion resistance and design performance if it is a metal plate. Therefore, it is more suitable for 30 玖, the description of the invention, and in the step of assembling the refrigerator, static electricity will be generated on the surface film of the metal plate used for the outer plate of the refrigerator due to friction with the conveying belt or other conveying machines, and The problem that dust will adhere to the surface of the metal plate. To solve this problem, it is necessary to impart conductivity to the coating film to release the static electricity accumulated on the surface of the 5 溥 film. If it is covered by the present invention In addition to the above carbon, the heat-absorbing film layer on the inner side of the refrigerator outer plate contains 1 to 50 parts by mass of conductive metal powder relative to 100 parts by mass of the binder solid content. It is more suitable to solve the problem of dust adhesion due to static electricity during the assembly step of the refrigerator. The structure for imparting electrical conductivity to the heat-absorbing film layer has also been described previously. When manufacturing the refrigerator of the present invention, the flat metal One side of the plate is coated with the heat-absorbing film layer of the present invention to make a pre-coated metal plate with high heat absorption, and after cutting and processing, it is assembled into a refrigerator. The heat-absorbing film layer is located on the outer plate. Inside, the working efficiency becomes higher, so it is more suitable for 15. In the manufacture of the refrigerator of the present invention, if a pre-coated metal plate covered with a heat-absorbing film is made in advance, cutting, processing, and assembly are then performed. As the method, a generally known processing method can be used. Examples include processing methods such as punching, bending, drawing, expansion, and roll forming. 20 'H) The present invention is that by applying the highly endothermic paint of the present invention to the inner surface side of an electronic machine case with built-in heat-generating electronic parts and batteries, the temperature rise inside the electronic device can be significantly suppressed. 31 200404673 玖, description of invention

In the present invention, the portable devices (mobile devices) and vehicle-mounted devices are not particularly limited, and include mobile phones, notebook personal computers, PMs, vehicle batteries, car navigation system devices, car audio devices, car control devices, and the like. 5 Heating electronic parts are not particularly limited, and refer to electronic parts such as CPU components, MPU components, DSP components, electronic integrated circuits, resistors, etc. There are also batteries that are generally known. The material used to form the casing of the portable or vehicle-mounted device of the present invention is also not particularly limited, and examples thereof include Mg alloy casing, A1 alloy casing 10, steel plate casing, other metal casings, and plastic casings. Etc. However, the present invention is particularly useful when Mg alloy cases, A1 alloy cases, and steel plate cases are particularly used. The heat-absorbing film layer of the casing of the portable device or the vehicle-mounted device of the present invention is in one aspect. In the aspect, it is 15 components relative to 1 mass part of the binder solid, and contains 1 to 20 mass parts with a particle size of less than 0.1. / zm carbon and 1 ~ 140 shell carbon with a particle size of 0.1 / zm or more and 50vm or less and carbon with a particle size of less than 0.1 // m and carbon with a particle size of 0.1 / zm or more and 50 # m or less The total is 10 to 150 parts by mass. In the second aspect, the heat-absorbing rhenium film layer is composed of 200 parts by mass of a binder solid content, 10-150 parts by mass of a heat-absorbing pigment, and 1-150 parts by mass of a conductive pigment. The heat-absorbing pigment is carbon black having an average particle diameter of 1 to 100 mii, and the conductive pigment is composed of sheet metal Ni and chain metal Ni having an average particle diameter of 0.5 to 50 / zm. The mass ratio of the metallic Ni / chain metallic Ni is from 0 to 6. 32 200404673 发明, description of the invention _ Quote λ, absorption 1 ±, in the third aspect, the special film layer is composed of ⑽ parts by mass of the binding agent solid content, 10 ~ 150 parts by mass of the heat-absorbing pigment and 10 ~ 150 Mass parts of ferrosilicon. Said ",,, absorption! ± 4 film layer in the fourth state of the towel, the binding agent ㈣ component with respect to the stomach 54" containing 50 parts by mass of HM iron. The specific contents of these various heat-absorbing film layers are basically the same as those previously described with respect to the shell of the heating element. Therefore, their specific details are omitted here. In addition, the casing of the heating element described above can also be used as a casing for a φ-belt type device or a vehicle-mounted device. 10 In order to form the highly endothermic film layer of the present invention on the surface of a casing, a film component containing a binder may be applied in a generally known coating form. For example, 3, coatings include solvent-based coatings that dissolve resin in a solvent, water-based coatings that disperse milk tablets into water, etc., powder coatings that pulverize resin and fight against each other, and 15-body powder coating, powdered resin dispersed in water, 15-body powder coating, ultraviolet (UV) hardening coating, electron beam (then hardening coating, film laminate that sticks the resin in a film shape, and melts the resin before coating Morphology, etc. The film thickness of the south heat-absorbing film should be 1 ~ 1000 // m. If the film is less than 1 / im ', it is not suitable because the film has poor heat absorption. If the film is larger than 20000 V m, because The heat absorption is saturated and not economical, so it is not suitable. "Among them, 10 to 500 is more preferable. In order to ensure the conductivity, it is more suitable to be greater than or equal to 1 // m and less than 10 / zm. Generally after forming the shell The surface thereof is coated with the highly endothermic film layer of the present invention, but in the case of a plate material, it can also be coated with 33 前, an explanation cloth in advance before the forming process. In the present invention, by covering the endothermic film layer with Surface as heating electronic parts and electrical The inside of the case of the battery can reduce the temperature inside the electronic device and the battery case. The structure of the case with the same characteristics as in Figure 3 and the heat absorption of the present invention can be similar to the system of the present invention by Mg. The alloy plate 1 is formed to cover the inner surface with a high heat-absorptive thin film layer 2. In addition, the electronic component or battery in the figure. If the surface covered with the high heat-absorptive thin film layer is not the inner surface of the case, the propagation method can be reduced. The effect of the temperature inside the electronic device casing. However, the heat absorbing film layer can cover the outside of the casing and also cover the outside. When S is also applied to the outside, the heat is equivalent to the heat radiation. It can easily release the heat absorbed in the metal plate that is the shell of the heating element, so the temperature of the redundant body itself will decrease, which is more suitable. It can also be covered with a colored coating film on the outside of the casing to give the design Appearance. The colored coating film layer can be multi-layered. If the shell is made of metal, the bottom layer can also be used as a rust-resistant coating film layer containing rust-proof pigments, and the upper layer is used as a work containing colored pigments. Color layer. In these cases, because the colored organic film layer (if it is a multi-layer coating film, it also includes the anti-rust coating film layer) itself has a certain degree of thermal radioactivity, so if the total coverage is 10 # m or more ' The temperature of the casing can be lowered, so it is more suitable.

Table 5 shows the evaluation results of the effects of the added pigment and the amount of the heat-absorbing film layer on the surface-coated plate. 20 It can be seen that the surface coating plate of the present invention (Examples 1-1 to 1-25 of the present invention) has a total emissivity of 0.70 or more in a region of a wavenumber of 600 to 3000 cm-1 measured at 80 ° C. The heat-absorbing surfaces of Comparative Examples 1-26 and 1-27 with emissivity less than 0.70 are suitable as the shell of a heating element. If the heat-absorptive film layer of the surface-coated plate of the present invention is composed of 100 mass 52 200404673 玖, a part of the binding agent solid content W mass parts of the heat-absorbing pigment and ㈣ mass parts of the conductive pigment, Since it is excellent in workability and electrical conductivity, it is more suitable. If the amount of the heat-absorbing pigment is less than 10 f parts (ratio &amp;) ', the emissivity is less than G · 7 and the heat-absorbing property is poor, so it is not suitable. If the addition amount of the heat-absorbing pigment is more than 15 G f parts (Example M of the present invention), although the emissivity is high, the workability such as bendability and punching formability is reduced ', it is preferably 150 parts by mass or less.

If the amount of conductive pigment is less than! Part by mass (In Example 10 of the present invention, since it becomes impossible to ensure conductivity, it is preferable to use at least f parts. If the addition amount of the conductive pigment is more than 150 parts by mass (Comparative Example ⑶), the conductive pigment will block The heat absorption is not suitable because the emissivity becomes less than 0.7 and the absorption is poor, and the processability of the thin film layer is also greatly reduced.

If the heat-absorbing pigment contained in the heat-absorbing film layer of the surface-coated plate of the present invention is a carbon black having an average particle diameter of 100 nm, and the aforementioned conductive pigments and buckets are composed of an average particle size of ~ 5 # m The flaky metal and the bond-shaped metal are construed, and the mass ratio of the flaky metal Ni / chain metal Ni is 0 ~ 6, since it is more excellent in heat absorption and conductivity, it is more suitable. If the heat-absorbing pigment has a larger particle size such as carbon powder and graphite powder (the present inventions 1-6 and I.), since the emissivity is low and the large heat-absorbing pigment will hinder the conductive effect of the conductive pigment, Since the electrical conductivity is also reduced, the carbon black having an average particle diameter of 1 to 100 nm is preferable for the heat-absorbing pigment. Electrical conductivity of the heat-absorptive film layer included in the surface-coated plate of the present invention 53 200404673 若 If the illustrative pigments of the invention are Ming powder and stainless steel powder, these conductive pigments can easily hinder heat absorption and add such conductivity Pigments (inventive examples μ15 and 1-16) have lower emissivity. Those composed of sheet metal Ni and chain metal Ni having an average particle diameter of 0.5 to 50 // m are not likely to hinder heat absorption, and are therefore very suitable. However, if the mass ratio of the platy metal Ni and the chain metal Ni is less than 0 (inventive example M1), the conductivity is reduced, and the mass ratio of the platy metal Ni and chain metal Ni is greater than 6 (example of the present invention) I-14) 'hinders heat absorption and lowers emissivity, so the mass ratio of sheet metal Ni / chain metal Ni is preferably 0-1. If the conductive pigment is ferrosilicon (the emissivity of the present invention will not decrease, and the corrosion resistance of the surface-coated board of the present invention is also mentioned, it is more suitable and those who only add ferrosilicon without heat-absorbing pigment (this Invention Example 19) is highly suitable because of its high emissivity and excellent conductivity and corrosion resistance. When conductive carbon black is used as a heat-absorbing pigment, it is more suitable because of its electrical properties. The present invention The heat-absorbing I * green film layer of the surface-coated board has a heat-absorptive pigment and a conductive pigment, and an anti-rust pigment is added (Example of the Invention ϊ · 22 i 1-25), which has excellent residual resistance Therefore, it is more suitable. -The evaluation results of surface-coated plates with different film thicknesses of heat-absorbing films are revealed ... Table 6 shows the square and small film thicknesses (the example of the present invention), the total emissivity is low, X, if Above 50㈣, the workability of the thin film layer is reduced, so the film thickness is preferably 1 ~ 50 # m. Table 7 shows the place before the chromate treatment as the heat-absorbing film layer. 54 200404673 (Inventive Examples 1-35), and those without pre-processing Evaluation results (Examples 1-36 of the present invention). Although the type of pre-treatment was changed, the emissivity, heat absorption, and other coating film properties did not change. However, chromium was generated by those who performed chromate treatment. The acid-treated thin 5 film contains hexavalent chromium for environmental protection, so it is more suitable for non-chromate treatment (non-chromate treatment). In addition, in the case where no pre-treatment is performed, due to the film adhesion and rice resistance It is more suitable to have a pretreatment. | Table 8 shows the results of the heat absorption evaluation when the heat-absorbing film layer is covered on only one side and the other side is not coated. The heat-absorptive film layer has a lower heat-absorption property than the one covering both sides. When covering only one side, the heat-absorptive film layer is covered on the outer side of the casing for covering the heat generating body that becomes a heat source (Comparative Example 1- 38), the heat absorption is almost ineffective and unsuitable. 15 (Example II) The following is a detailed description of the method of making and forming the heat-absorbing surface coating board used in the experiment.

However, this test is carried out in a state where the coating film on the a-side side is the damaged portion of the coating film, and the test is performed. 5) The press forming test is the same as in Example 1. However, this test is performed so that the side of the a-plane is outside the force 4 and the state of the coating film damage on the a-plane is observed and evaluated. 6) Pair | Insect resistance 10 Pairs of the prepared surface-coated panels were subjected to a water spray test using the method described in m-K5400.9.1. Water test is sprayed on the a side of the test piece. Let the test time be the following. Observe the white ore of the flat surface and the end surface on the a side of the surface = the state of the surface. There is no white rust on the flat surface and the end surface. When no white ore is generated, it is rated as △ when white rust is generated on the end surface portion and white records are locally generated on the flat surface portion. It is rated as △, and when white rust is generated on the end surface and flat surface area, it is evaluated as X. 7) Conductivity test The same as in Example 1. However, this test is performed on the a side. 8) Observation of the timing state of the endothermic paint &gt; 〇-After placing the endothermic paint applied on the a side of the metal plate at room temperature for ^ months, the state of the coating liquid was visually observed and evaluated as follows. Compared with the state when the coating liquid is made, there is no change ... Compared with the state when the coating liquid is made, the viscosity increases: △ Compared with the state when the coating liquid is made, the coating liquid becomes condensed Gelatinous or solidified 60 200404673 玖, description of the invention

: X 9) Appearance of endothermic film The appearance of the film covering the a side of the metal plate was visually observed and evaluated as follows. 5 Smooth appearance: 〇 Because the pigment is only slightly more than the thickness of the film, it can be observed that the surface of the film has a slightly concave and convex appearance ·· △

Since pigment is added much more than the film, it can be observed that the film surface has a sharp uneven surface: X 10 or less, details of the evaluation results are detailed. The surface-coated plate of the present invention is obtained by covering a heat-absorbing film layer with a dry film thickness of at least the above to obtain a surface-treated metal plate with high heat absorption, and the heat-absorbing film layer is bonded to 100 parts by mass. The solid content of the agent contains 1 to 20 parts by mass of carbon with a particle size of less than 0 # m and 15 1 to 14 parts by mass of carbon with a particle size of 0.1 / zm or more and 50 / zm or less, and the particle size is less than 0 · The total of carbon of 1 // ηm and carbon having a particle size of 0.1 / zm or more and 50 // m or less is 10 to 150 parts by mass. When a heat-generating-body casing is produced using the surface-coated plate of the present invention, it is necessary to use a heat-absorbing film as the inner side of the heat-generating-body casing. When the heat-absorbing film of the present invention is covered only on the outer side of the heating element casing (Comparative Example π_32), the temperature (endothermic temperature A) inside the casing is hardly reduced, which is not suitable. In the heat-absorbing film layer of the surface-coated plate of the present invention, the total emissivity is less than 61 200404673 in a region with a wavenumber of 600 to 3,000 cm-] measured at a temperature of 80 ° C, and a description of the invention. In the case of 70% (Examples 11-26 of the present invention), since the temperature (endothermic property • temperature A) inside the housing is hardly reduced, the total emissivity is preferably 0.70 or more. When a conductive pigment is added to the heat-absorptive thin film layer of the present invention (Example Π · 11 of this invention), since conductivity is imparted, it is more suitable for applications such as requiring the grounding of the heating element casing. When the anti-reading pigment is added to the heat-absorbing film layer of the present invention (Example of the present invention; tM3, 11-14), the corrosion resistance is improved, so it is more suitable for applications requiring corrosion resistance. Furthermore, ferrosilicon with both corrosion resistance and conductivity is added to the heat of the present invention.

In the case of an absorptive thin film layer (Example IM2 of the present invention), it is more suitable because it imparts conductivity and improves recording resistance outside Z. In addition, if the heat absorbing film is covered only on the inside of the heating element case and nothing is covered on the outside, although the temperature inside the case (endothermic temperature A) is low and the heat absorption is excellent, the temperature of the metal plate itself (endothermic temperature B) )high. Therefore, it is more suitable to coat a heat absorbing film on the inside of the heating element casing 15 and also cover the heat absorbing film of the present invention or a generally known colored coating film on the outside 10 m or more. (Example III) Hereinafter, a method for producing a heat-absorptive surface-coated plate used in experiments will be described in detail. A hot-dip galvanized steel sheet (GA) having a thickness of 0.6 mm on both sides with a plating adhesion amount of 60 g / rn2 per one side was impregnated with a commercially available alkaline degreaser manufactured by Japan Parker Raijin Co., Ltd. "FC-364S" was degreased by diluting it into an aqueous solution having a concentration of 20% by mass at a temperature of 60 ° C for 10 seconds, thereby degreasing, 62 200404673, the description of the invention, and washing with water and drying. In addition, an aluminum-plated steel plate (aluminum steel plate) and an aluminum plate (AL) having a thickness of 0.6 mm were plated at a thickness of 60 g / m2 per one side of the plating adhesion amount on both sides, and were immersed in alkaline degreasing for commercial aluminum "FC-315" manufactured by Japan Parker Laichengu Co., Ltd. was diluted into an aqueous solution of 70C at a concentration of 40% by mass for 10 seconds, thereby degreasing, washing with water, and drying. Then, the chemical conversion treatment liquid was applied to a degreased electroplated steel plate and an aluminum plate using a roll coater, and dried by hot air at a temperature where the plate temperature reached 60 °.

10 In the present test, the chemical conversion treatment is a commercially available non-chromate treatment. Ben Parker Lai Zhen Gu Gong 3 is called "CT Marriage G". The chemical conversion treatment is carried out by using a roll coater on both sides of the metal plate, and it is dried at a plate temperature of 6 (rc). The amount of chromate treatment is set to 5Gmg / m2. The adhesion amount is 2000 mg / m2 in terms of the total film amount. 15 20 Further, the coatings shown in Table i of the Example! Are applied using a roll coater: 1-2 are applied to the electric fairy that has been chemically treated. The single side of the board (the following: this side is the a side) ', and the drying and hardening conditions are achieved by using an induction heating furnace with hot air. The reaching plate temperature (PMT) is 23Qt: By using &gt; The chemical conversion treatment and the heat-absorbing film coating are applied on one or both sides to obtain a test piece. Also, the other side (hereinafter referred to as this side as the b side) is made; the color coater. In addition, the color coating is applied by Japan Coatings Co., Ltd. The base coat "FL641 primer" is used only for pre-coating steel to a dry film thickness of 5 ".

For the surface-coated plate of the present invention, if the original plate is an iron-zinc alloy steel plate such as hot-dip alloyed zinc steel plate (Example IIM of the present invention), the emissivity will be iron, and it is more suitable. In addition, if the original plate is made of a material having high thermal conductivity such as aluminum (Inventive Example 111-3 of the present invention 20), and those materials are plated on steel materials (Inventive Example III-2) The surface of the medium or metal plate is more divergent, and the heat of the surface of the metal plate is uniform, so it is more suitable.

Time-off: Addition of pigment in heat-absorbing film layer of Δ The results are shown in Table 12. In addition, the test results of the samples of the heat-absorbing film of Table 12 coated on non-metal 70 200404673 玖, description of the invention on both sides of the board. It can be seen that the surface coating plate of the present invention (iVfcl ~ 20 of the present invention) has a total emissivity of 0.70 in a region where the wave number is measured at 60 ° C to 300 ° cni-i at any temperature of 80 C or higher. As described above, Comparative Examples 21 and 22 having higher emissivity than 701 have higher heat absorption properties, and are suitable as a casing of a heating element. If the heat-absorbing film layer of the surface-coated plate of the present invention is composed of 100 parts by mass of the solid content of the binder, 10 to 150 parts by mass of the heat-absorbing pigment, and 1 to 150 parts by mass of the conductive pigment, It is more suitable to be excellent in workability and electrical conductivity. If the amount of the heat-absorbing pigment is less than 10 parts by mass (Comparative Example ιν · 21), since the emissivity is less than 0.7, and the heat-absorbing property is poor, it is not suitable. If the addition amount of the heat-absorbing pigment is more than 150 parts by mass (Example IV-5 of the present invention), although the emissivity is high, the impact resistance is reduced, so it is preferably less than the working part. If the added amount of the V ΙΓΙ pigment is less than 1 part by mass (Example of the invention ιν_ $) ', since it becomes impossible to ensure conductivity, it is more preferable to use 丨 part by mass or more. 'If the electrical pigment is more than 15 mass parts (Comparative Example IV_22), since the conductive pigment will hinder heat absorption, the emissivity becomes less than 0.7 and the heat absorption is poor, and the impact resistance of the thin film layer is also greatly reduced. So it is not appropriate. If the heat-absorbing pigment contained in the heat-absorbing film layer of the surface-coated plate of the present invention is a carbon black having an average particle diameter of 1 to 100 nm, and the conductive pigment is an average particle diameter of 0.5 to 5. If the sheet metal Ni and the chain metal Ni are composed of // m, and the mass ratio of the sheet metal Ni / chain metal Ni is 〇6 ~ 6, it is more suitable because it has better heat absorption and electrical conductivity. 71 200404673 发明, description of the invention If the heat-absorbent pigment has a larger particle size such as carbon powder and graphite powder (this month's IV 6 and IV-7), the emissivity is low, and it will hinder the conductive color; Dou Zhi The effect is to reduce the electrical conductivity, so the carbon black with an average particle diameter of 1 to 100 nm is preferred for the heat-absorbing pigment. If the conductive pigment of the heat-absorbing film layer is coated on the table of I s in this month, if the conductive pigment of the heat-absorptive film layer is 1 lum powder and stainless steel powder, these conductive pigments will easily hinder the heat absorption and add these conductive pigments. (Examples of the invention ιν_ΐ5 and IV-16) tend to decrease the emissivity. A conductive pigment composed of a plate-like metal Ni and a chain-like metal region 10 having an average particle diameter of 0.5 to 50 # m is not likely to hinder heat absorption, and is therefore very suitable. However, if the mass ratio of the flake metal Ni and the chain metal chaos is less than 〇1 (Example IV-11 of the present invention), the conductivity is lowered, and the mass ratio of the flake metal Ni and the chain metal Nl is greater than 6 (this Invention Example 1λM4) tends to hinder heat absorption and lower the emissivity, so the 15 mass ratio of sheet metal Ni / chain metal river is preferably 0.1 to 6. If the conductive pigment is ferrosilicon (Example IV_17 of the present invention), since the emissivity does not decrease, it is more suitable. Those who do not add a heat-absorbing pigment and only add Shixi Iron (Example n 19 of the present invention) are very suitable because they have high emissivity and excellent electrical conductivity. 20 Also, when conductive carbon black is used as the heat-absorbing pigment, it is more suitable because it can improve the conductivity. Table 13 shows the evaluation results of the surface-coated boards with different heat-absorbing film layer thicknesses. In addition, each of Table 13 is a test result using a sample in which a heat-absorptive film having the same conditions was applied to both sides of a non-metal plate. 72 200404673 玖, description of the invention The film thickness of less than 1 // m (Example IV-23 of the present invention) tends to decrease the total emissivity, so the film thickness is preferably 1 // m or more. Table 14 shows the results of the heat absorption evaluation in the case where the heat absorption film layer was covered only on one side and the other side was not coated. When only one side is covered, the heat absorbing film layer is applied to the outside of the case for covering the heat generating body that becomes a heat source (Comparative Example IV-31). The heat absorption is almost ineffective and unsuitable. (Example V) Hereinafter, a method for preparing a heat-absorbing coating plate used in experiments will be described in detail.

The details of the evaluation results are detailed below. The evaluation results are not shown in Table 17. The refrigerator of the present invention achieves the purpose of reducing the temperature of the inside of the refrigerator 5 by covering a heat-absorbing film on the inner surface of a metal outer plate, and the heat-absorbing film is 8 (TC above 200 C) In a region where the wave number is from 600 to 300 km · at a certain temperature, the total emissivity is above 70. The emissivity of the heat-absorbing film is less than 0.70 (83), Comparative Example VII-17 , VII-18, VII_20, νΠ-21), the internal temperature of the refrigerator is not much different from that of the conventional type, so it is not suitable. The heat-absorbing film coated on the outer plate of the refrigerator of the present invention, If the solid content of the binder is 100 to 150 parts by mass, the emissivity of the heat-absorbing film becomes more than 0.70, which is more suitable. The amount of carbon added is less than 10 parts by mass ( Comparative examples vn_17, VII_18, 20) or those not covered with a heat-absorbing film (comparative example νπ_21), the emissivity is less than 0.70, which is not suitable. Also, the amount of carbon added is greater than 15 mass parts (comparative example VIM9), because The workability is poor, so it is not suitable. If a conductive pigment is added to the heat-absorbing film of the board, since it imparts conductivity, static electricity is less likely to be generated when the refrigerator is assembled, and there is no problem of dust adhesion caused by static electricity. It is more suitable when no conductive pigment is added (Examples of the invention VII-6, VII-8, Vii-9), the conductivity is poor. Those with anti-rust pigment added to the heat-absorbing film of the refrigerator outer plate of the present invention (Examples VII-7, VII-8, VII-9 of the present invention) ), Excellent corrosion resistance, and more suitable. Especially those added with ferrosilicon (Example VII-7 of the present invention), because it has excellent conductivity in addition to corrosion resistance, it is more suitable. Outside the refrigerator of the present invention The endothermic film of the board contains 100 parts by mass of the binder solid content, and carbon particles having a particle size of ijO smaller than Q1 and particle sizes of the mass by 0/1 / m or more and 50 # m or less. It is broken, and the total of carbon with a particle size smaller than 0.1 vlm and carbon with a particle size of 0 // m to 50 Vm is 10 to 15 parts by mass (Example VII_22 of the present invention, νΐΙ · 23). A large amount of carbon is added to the heat-absorbing film, but the viscosity of heat-absorbing paint is not easy to increase, so it is more 200404673 (1) Description of the invention Before the outer panel of the refrigerator of the present invention is coated with a heat-absorptive film, if it is custom-made in advance, it has excellent adhesion and processability, which is more suitable. Those who have not undergone a chemical treatment (Example VII- 12), adhesiveness and processability 1. Furthermore, any kind of chemical conversion treatment is acceptable, but compared with 5 using chromate treatment (Example of the present invention VIM1), non-chromate treatment, In consideration of environmental issues, it is more appropriate. (Example VIII) Hereinafter, a method for producing a heat-absorbing coating plate used in experiments will be described in detail. 10 Using a bar coater, apply the heat-absorbing film coating material shown in Table 4 to the inner surfaces of the silk alloy sheet and the magnesium alloy sheet, and allow them to dry at room temperature for about 24 hours. Details of the finished surface-coated board are shown in Table 19 (A1 alloy plate) and Table 20 (Mg alloy plate). For the surface-coated plates shown in Tables 19 and 20, either of them is the same type of heat-absorbing film layer 15 covered on both sides under the same conditions. The details of the evaluation test of the prepared surface-treated plate are described below. 1) The measurement of the emissivity of the surface-coated board material is the same as in Example IV. 2) Measurement test 20 for heat absorption of the surface-coated board material is the same as in Example IV. 3) The impact resistance test of the coating film was the same as in Example IV. 4) Observation of the time-series state of the endothermic coating As in Example II, each endothermic thin film coating applied to the alloy plate and the town alloy plate 85 200404673 发明, description of the invention was evaluated. 5) Appearance of endothermic film The appearance of the film covering the aluminum alloy plate and the magnesium alloy plate was visually observed, and evaluation was performed in the same manner as in Example II. 5 The details of the evaluation results of the prepared surface-coated board are described below. As shown in Tables 19 and 20, the surface-coated plate of the present invention is obtained by coating a heat-absorptive film layer with a film thickness of 1 # m or more to obtain a surface-coated plate with a high heat-absorptive property. The film layer contains 1 to 1 part by mass of a resin solid content, and contains 1 to 20 parts by mass of carbon having a particle size of less than 0 10 and carbon particles having a particle size of 5 to # 0 m in parts by mass of pmo, and the particle size is less than 0. The total of .1 / zm carbon and carbon having a particle size of from 0.1 // ηι to 50 // ιη is 10 to 150 parts by mass. 15 86 20 200404673 Rose, invention description

The bell is thereby degreased, and after being washed with water, it is allowed to dry. Furthermore, a commercially available non-chromate-treated rCTE_300 "manufactured by Japan Parker Raijin Co., Ltd. was applied thereon using a roll coater, and the amount of dry adhesion was 200 mg / m2. Next, the heat-absorbing film coating material described in Table 1 was applied to a degreased aluminum alloy plate by a roll coater, and dried and hardened by using an induction heating furnace with hot air. The drying and hardening conditions are such that the reaching plate temperature (pMT) is 230 ° c. A test piece is obtained by applying a heat-absorbing film coating on one or both sides as needed. Details of the finished surface-treated alloy plate are shown in Table 22. In each of the aluminum alloy plates listed in Table 22, the heat-absorbing film layer is only covered on one side and the other side is not covered. 200404673 Rose, Invention Description Conductivity 〇 &lt; &lt; &lt; 1 &lt; &lt; 1 &lt; 3 X 〇〇X &lt; 1 &lt;] 〇〇0 &lt; 3 〇〇 &lt;] &lt; 3 &lt;] &lt; &lt;] &lt; 3 〇〇〇But &lt; &lt; 3 &lt; 1 &lt; 3 &lt;] &lt; 3 &lt; 1 &lt; 1 &lt;] &lt; 1 &lt; 1 &lt; \ &lt;] &lt;] &lt; &lt;] 〇 &lt; 1 0 &lt; 3 〇 〇〇〇〇〇〇 &lt; 3 &lt; 3 &lt; 3 | Opposing * β edge m &lt; 3 &lt; 3 &lt; &lt; 3 0 &lt;] &lt; 3 &lt;] &lt; t &lt; &lt;] &lt; &lt; 3 &lt; 3 &lt;] &lt; 3 〇 &lt; 3 〇〇 〇〇〇〇 〇 〇 &lt; 3 &lt; 3 &lt; 1 Press formability 〇〇 &lt; &lt; X 〇〇〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 X 〇 | Bendability 〇 ＆ lt; &lt; 3 X 〇 〇 〇 〇〇〇〇 〇〇〇〇〇〇〇〇〇〇〇〇〇〇〇〇〇〇〇〇〇 Coating film adhesion j 〇〇〇〇〇〇〇〇〇〇〇〇〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 0 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇〇〇〇〇〇0 o &lt; 1 〇〇〇〇〇〇〇〇 &lt; &lt; 3 &lt; 1 〇〇 〇〇〇〇〇〇 〇 XX &lt; | 0.80 | 1 0.91 1 1 〇, ^ 4j 1 0.95 1 1 0.95 | 0.80 1! 0.78 II 0.81 '' L〇.92j L0.80 '' I 0.92! 1 0.92 0.93 1 0,72 1 0.72 '' 0.73 1 L 0.95 I i 0.92 I i 0.80 0.93 S ο 1 0.81 0.80 I 0.82 '' 0.80 I 0.65 1 0.65 I 1.65 film thickness | = t LO B = 1 1〇Η 3.

The measurement of the emissivity of the aluminum alloy plate is the same as in Example 1. 2) The heat absorption measurement test of the aluminum alloy plate is the same as in Example IV. 3) Coating film adhesion test The same as in Example 1. 4) Bend test of coating film The same as in Example 1. 5) Press forming test The same as in Example 1. 6) Corrosion resistance The water spray test was performed on the manufactured aluminum alloy plate by the method described in JIS-K54009. The water test is on the side of the heat-absorbing film layer. Let 15 test time be 500h. ^ The evaluation method of the coating film at the cross section is rated as 0 when the maximum blister width on one side of the cross section is less than 2 mm, and when it is greater than or equal to 2 mm and less than 5 mm, it is rated as △ '5 mm or more. In addition, the flat plate made of the evaluation surface side of the burr 20 at the time of cutting (when it becomes the upper burr 1 mm) was also subjected to the alkali water spray test, and the blister width of the coating film from the end surface was observed. The evaluation method of the end surface portion is rated as 0 when the foaming width from the end surface is less than 2 surfaces, 2mm or more and less than 5mm, and the external method λ, 11111 8 is rated as △, and 5% or more as X.

Burst) Produced from coated steel sheet 92 200404673 玖, description of invention 7) Conductivity test Same as in Example 1. Table 22 shows the evaluation results of the effects of the type and amount of the pigment added on the heat-absorbing film layer covering the aluminum alloy plate. 5 It can be seen that the aluminum alloy plate of the present invention (Examples X-1 to X-25 of the present invention) has a total emissivity of 0.70 or more in a region of a wavenumber of 600 to 3000 cm · 1 measured at a temperature of 80 C, so the emissivity is relatively Comparative examples χ-26 and χ_27, which are smaller than 0.70, have high heat absorption and are suitable as a casing of a heating element. If the heat-absorbing film layer of the aluminum alloy plate of the present invention is composed of 100 parts by mass of 10 parts of a binder solid content, 10-150 parts by mass of a heat-absorbing pigment, and 1-150 parts by mass of a conductive pigment, Since it is excellent in workability and electrical conductivity, it is more suitable. 15

If the amount of the heat-absorbing pigment is less than 10 parts by mass (Comparative Example χ_26), the emissivity is less than 0.7 and the heat-absorbing property is poor, so it is not suitable. If the addition amount of the heat-absorbing pigment is more than 15 parts by mass (Example of the present invention

X-5) ', although the emissivity is high, the workability such as bendability and press formability is reduced, so it is preferably 150 parts by mass or less. If the addition amount of the conductive pigment is less than 1 part by mass (Inventive Example X-8) ', since it becomes impossible to ensure conductivity, it is preferably 1 part by mass or more. If the conductive pigment is added in an amount of more than 15 mass parts (Comparative Example χ_27), since the conductive pigment will hinder heat absorption, the emissivity becomes less than 0 and the heat absorption is poor, and the processability of the thin film layer is also greatly reduced. So it is not appropriate. The heat absorption of the heat-absorptive thin film layer of the chain alloy plate of the present invention 93 200404673 玖, if the illustrative pigment of the invention is carbon black with an average particle diameter of hiOOnm, and the conductive pigment is composed of an average particle diameter of 0.5 to 5 ~ 50 // m composed of sheet metal Ni and chain metal Ni 'and the mass ratio of sheet metal Ni / chain metal Ni is 0 · ΐ ~ 6, because it has better heat absorption and electrical conductivity, so it is more suitable. 5 If the heat-absorbing pigment has a larger particle size such as carbon powder and graphite powder (X-6 and X-7 of the present invention), the emissivity is low, and the large heat-absorbing pigment will hinder the conductivity of the conductive pigment As a result, the electrical conductivity is also reduced, so the carbon black having an average particle diameter of 1 to 100 nm is preferred for the heat-absorbing pigment. If the conductive 10 pigment contained in the heat-absorbing film layer of the aluminum alloy plate of the present invention is aluminum powder and stainless steel powder, these conductive pigments will easily hinder heat absorption, and those who add these conductive pigments (this Inventive Examples and X-16) Emissivity decreases. Those composed of plate-like metal Ni and chain-like metal Ni having an average particle diameter of 0.5 to 50 mm are not likely to hinder heat absorption, and are therefore very suitable. However, if the mass ratio of the flake 15 metal N1 and the chain metal Ni is less than 0.1 (inventive example χ_11), the conductivity is reduced, and the mass ratio of the flake metal Ni and the chain metal Ni is greater than 6 ( Example X-14 of the present invention) hinders heat absorption and lowers emissivity, so the mass ratio of sheet metal Ni / chain metal Ni is preferably (). ^ 6. If the conductive pigment is ferrosilicon (the example of the present invention χ_17), the emissivity will not decrease, and the corrosion resistance of the aluminum alloy plate of the present invention will be improved, so it is more suitable. Those who added no iron-absorbent pigment and only added Shiyu Iron (Example 19 of the present invention) have high emissivity and excellent conductivity and corrosion resistance, so they are very suitable. When conductive carbon black is used as the heat-absorbing pigment, it is more suitable because it can improve the conductivity. In the heat-absorbing film layer of the aluminum alloy plate of the present invention, in addition to the heat-absorbing pigment and the conductive pigment, a rust preventive pigment is added (Examples of the present invention χ_22 to X-25), which is more suitable because of its excellent corrosion resistance . 5 Table 22 shows the evaluation results of aluminum alloy plates with different heat-absorbing film layers. Since the film thickness is less than 1 // m (example of the present invention χ · 28), the total emissivity is low, and if it is greater than 50 # m, the processability of the thin film layer is reduced, so the film thickness is preferably 1 ~ 50 // m . Industrial Applicability 10 With the present invention, it is possible to establish a technology for dissipating heat generated inside a home appliance that uses a large number of motors, electronic parts, and the like as a heat source internally. Furthermore, it is possible to provide a surface-treated material suitable for dissipating heat and having excellent conductivity for grounding an electric product. With this technology, the performance of home appliances including refrigerators can be improved, and energy consumption can also be reduced. Similarly, mobile phones, notebook personal computers, PDAs, car battery cases, car navigation systems, car audio devices, and car control devices that can rise in temperature inside the device due to built-in electronic parts and batteries can also be applied. The technology of the present invention, which has the effects of improving the moonlight and reducing the energy consumption, etc., is a technology that has high industrial applicability. Therefore, the present invention can be said to be a highly valuable invention in the industry.
