Description

The present invention relates to a composition that utilizes a shell that is disposed of in large quantities and then becomes industrial waste after the shell meat portion is edible, and manufactures a shell composition and a molded product thereby, Needed not only in the fields to be sold, but also in the fields that provide the materials and parts necessary for them, the fields that provide the machinery and tools necessary to process these materials and parts, and those materials, machinery, and parts Field of materials such as wood, plywood, plastics, various metals, etc., field of various measuring instruments required for their production and assembly, field of power machines that drive processing machines for their production and assembly In addition, the power included in the energy, the electricity that is the energy source, the field of electric oil, and the field that is generally included in the field generally referred to as industrial machinery, and further, the shell composition is tested and deployed. Efficiently collects, transports, and collects scraps and wastes, etc. There are few technical fields that are almost unrelated to the recycling field to be recycled and new fields that cannot be envisaged at this time.

(Viewpoints)
Japan, which was blessed with abundant marine resources surrounded by the sea, continued to fulfill its appetite while becoming prosperous and luxurious, resulting in the depletion of resources, as if it were natural It is a time when almost no seafood can be provided from the natural world, and almost all seafood must rely on imported goods from foreign countries and artificial products that are supplied by cultivating fisheries along the coast. For a long time, shellfish are no exception, and now most high-class shellfish such as scallops and oysters are produced in large quantities by established advanced aquaculture technology, and of course they are tasted with various ingenuity as general household dishes. In addition, shellfish dishes provided by skillful cooking methods have gained high support from general consumers as popular menus at restaurants, etc., and are consumed in large quantities in response to these demands. As a result, a large amount of shells are generated as a result of the consumption of shellfish, and it is natural that the amount of shells that can be stacked and processed like an old shell mound is not limited. Even if only the amount that can be produced is consumed, because of the odors and pests that are generated when left unattended, it is regulated by itself, so for those who handle shellfish, the problem of processing shells that are now treated as industrial waste This has been a major concern for many years for shellfish farming and people who benefit from it, and one of the countermeasures is the disposal of shellfish effectively.

(Conventional technology)
Such attempts have been taken up in various ways so far and have never been put into practical use. For example, in the old days, they were used for concrete aggregates or applied to decorative concrete boards embedded in surfaces. As a result, a so-called crushed shell is used as a main raw material as disclosed in Japanese Patent Application Laid-Open No. 7-304035 “Shell Shell Resin and its Molded Product Manufacturing Method”. A mixture obtained by mixing appropriate amounts of materials, hardeners and effect accelerators to solidify them into tiles, blocks, U-grooves, flower pots, etc., molded articles such as fish reef blocks, etc. An attempt to replace civil engineering and construction materials represented by the invention of Japanese Patent Laid-Open No. 9-158106, “Paving method of road”, etc. One in the limelight as of, actually has a track record of commercialization has been promoted as a promenade of tiles and paving material such as a temporary park.

However, these attempts are merely substitutes for traditional tiles and paving materials, and the added value as a product is not recognized except for the name of recycling. On the other hand, the product cost is higher than the previous one. However, even if it is adopted to the place where the big name is attached, it does not spread to the general public, and even if it is adopted meaningfully, shellfish growing in the sea will be salinized in its shell components no matter how much it is washed. When used and mixed in concrete resin and asphalt due to materials such as containing porcelain and porcelain, the weakening of solid strength due to the progress of oxidation, and thermal expansion and contraction due to solar heat The deterioration of the material strength due to the difference included a fatal weakness that could not be avoided, and there was a grudge that lacked reliability.

(Awareness of problems)
As mentioned above, many proposals for effective use of shells discarded in large quantities are natural for Japan, which has continued to eat shellfish as one of the marine resources, and there is no novelty. In fact, the inventor himself has been involved in the problem of shell processing for a long time as one of the people who lived in Aomori for a long time in Aomori Prefecture, one of the most prominent scallop farming products after apple. Although I have been asking the world about the results of research and development each time, so far I have not been able to escape from the area where the lime carbonate, which is a shell component, is simply caught by the same kind as other inorganic materials. The shell is captured only as a shell as an alternative to something, and as a result, the pursuit of economic effects and the improvement of the strength of the material that comes from salt are inevitable. However, there was a structure unique to the shell, that is, the mantle covering the surface of the body, and the mantle was also formed on the mantle. Despite having a structure that usually consists of three layers and the outermost layer forms a pearl layer and has a strong tendency to delaminate when crushed, effective utilization of shells utilizing this structure is effective. It has become so quiet until now.

(Object of invention)
This invention, from the above awareness of the problem, the effective utilization of the shell in accordance with the shell structure can be solved at once, the development of the research, research has begun quickly, As a result of repeating trial and error over a long period of time and many trial manufactures and experiments, this time finally succeeded in realizing a shell structure composition of a novel structure, and a method for producing a molded product thereby, In the following, the configuration will be described in detail together with an embodiment representative of the present invention.

(Structure of the Invention) This invention is based on a shell piece composition and basically comprises the following structure.
In other words, a large amount of flat shell shell fragments obtained by crushing and sorting shells are added alone or with an appropriate amount of low water-absorbing mineral particulates as a bulking material, and with a binder made of synthetic resin as appropriate, most flat shell shells A small shell composition having a gist of a configuration in which small pieces are arranged in the same direction as the flat surface or inclined in that direction and are mixed and mixed as appropriate, and are appropriately compressed and solidified. It is.

    In other words, the shell piece composition of the present invention having this basic structure is composed of a large amount of flat shell pieces obtained by crushing and selecting shells, either alone or as an extender, in an appropriate amount of low water-absorbing mineral particulates. In addition to the body, with a binder made of synthetic resin as appropriate, most of the flat shell pieces are aligned in the same direction or inclined in that direction, so that they are also mixed in them. By suitably compressing and solidifying, the shell cross-section composition having a laminated structure in which the longitudinal cross section is torn and broken is obtained.

    In this shell composition of the basic composition, a large amount of flat shell fragments obtained by crushing and sorting shells are added alone or added with an appropriate amount of low water-absorbing mineral particulates as a filler, and then hardened. Adhesive force applied between the flat surfaces of the flat shell shell pieces that are adequately kneaded with rock wool or glass wool equivalent to 10 to 30% of the resin weight and an appropriate amount of a binder made of an appropriate synthetic resin to which an agent and a curing accelerator are added Due to the difference between the force and the adhesive force in the direction parallel to the flat surface, most of the flat shell shell pieces have the same flat surface as that of the kneading direction or the posture inclined to that direction. It includes a shell piece composition having a structure that is aligned and appropriately compressed and solidified.

    To show this more concretely, the shells are crushed and selected so that the diameter or major axis is about 1 to 8 mm, preferably about 5 mm, and the majority of them are taken around each contour. A large amount of flat shell shell pieces formed by smooth molding of the crossing edge shape, either alone or with an appropriate amount of low water-absorbing mineral particulates added as a filler, combined with a hardener and hardening accelerator as appropriate Adhesive force applied between the flat surfaces of the flat shell shell pieces and the adhesive force in the direction parallel to the flat surfaces, adequately mixed with rock wool or glass wool corresponding to 10 to 30% of the resin weight. With the difference between the most flat shell pieces, those with a flat surface in the same direction as the kneading direction or slanted in that direction are also mixed in them. Yichun compression, it can be said that shells pieces composition comprising solidified.

    More specifically, the shells are crushed and selected to have a diameter or major axis of about 1 to 8 mm, preferably about 5 mm, and more than half, and the edge shape over the entire circumference of each contour is smooth. A large amount of flat shell shells formed by molding, either alone or with an appropriate amount of low water-absorbing mineral particulates added as an extender, an appropriate synthetic resin, preferably urethane, to which a curing agent and a curing accelerator are added Adhesive strength and flatness that are adequately mixed with rock wool or glass wool equivalent to 10 to 30% of the resin weight, and applied between the flat surfaces of these flat shell shell pieces. Due to the difference in adhesive strength in the direction parallel to the surface, most of the flat shell shell pieces have the same flat surface as the kneading direction or a posture inclined in that direction. Also aligned to those with mixed shape thereof, the appropriate compression, shell pieces compositions shall become solidified.

    And if it shows as a thing of a desirable aspect, while crushing and selecting a shell, a diameter or a major axis is about 1-8 mm, Preferably it is about 5 mm among them, and occupies the majority, and each outline perimeter Flat shell shell pieces formed by smooth molding of the peripheral shape over 50 to 85%, and other types such as colored calcined cinnabar, crushed glass and natural ore grains with a particle size of 30 to 70 mesh. The mixture of the water-absorbing mineral particles is a suitable synthetic resin to which a curing agent and a curing accelerator are added, preferably an appropriate amount of a binder composed of a urethane-based synthetic resin or a vinyl ester-based synthetic resin, and a resin weight of 10 to It is sufficiently kneaded with rock wool or glass wool equivalent to 30%, and the viscosity applied between the flat surfaces of these flat shell shell pieces. Due to the difference between the force and the adhesive force in the direction parallel to the flat surface, most of the flat shell shell pieces are mixed in the same flat surface as the kneading direction or inclined in that direction. It can be referred to as a shell piece composition that is aligned, appropriately compressed and solidified.

And in connection with the above-mentioned shell piece composition, this invention includes the manufacturing method of a flat piece composition.
That is, an appropriate amount of a binder made of an appropriate synthetic resin to which a curing agent and a curing accelerator are added is added to a large number of flat pieces including flat shell pieces, and kneading is continued for a predetermined time. By utilizing the difference between the adhesive force acting on the flat surface of the flat small piece generated in the process of increasing the viscosity and causing the stringing phenomenon and the adhesive force acting in the direction perpendicular thereto, most of the flat shell shell pieces are The flat surface is the same as the kneading direction or in a posture inclined in that direction is also aligned to those mixed, so that a large number of flat pieces are torn and stacked in a jointed laminated structure, This is a method for producing a flat piece composition having a configuration in which a large number of flat pieces are bonded and solidified while maintaining a fine gap between the flat pieces.

Mixing time depends on the quality and size of the flat shell pieces, the quality and quantity of the filler, the quality and quantity of the binder used, and the type and proportion of the curing agent and curing accelerator to be added. The process of continuing kneading until most of the flat shell shell pieces are aligned with the flat surface in the same direction as the kneading direction or in a posture inclined to that direction. This is a method for producing a molded article by the shell piece composition of the present invention, which comprises the steps of quickly taking out the kneaded product in a state and filling it into a mold according to the intended use, suitably compressing and solidifying, and the above steps.

    More specifically, the process of crushing the shells and selecting them so that the diameter or major axis is about 1 to 8 mm, preferably about 5 mm of them, and occupying the majority, and the outline of each of the selected shell crushes The process of forming a large number of flat shell shell pieces by applying a smooth molding process to the peripheral edge shape with a shaping machine, addition of appropriate amounts of curing agent and curing accelerator, kneaded binder made of appropriate synthetic resin, A process of mixing and kneading rock wool or glass wool corresponding to 10 to 30%, and a large number of flat shell shell pieces, either alone or as a mixture with an appropriate amount of low water-absorbing mineral particulates added as a filler, The appropriate amount of binder containing rock wool or glass wool is added, and the quality and size of the flat shell pieces, the quality and quantity of the extender, and the quality and quantity of the binder used. The kneading time is adjusted according to the type and ratio of the curing agent and curing accelerator added to it, and most of the flat shell shell pieces have the same flat plane as that of the kneading direction or those with a posture inclined in that direction. A step of continuing kneading until the mixture is prepared in a mixed state, a step of quickly taking out the kneaded product in that state and compressing and solidifying it into a flat plate of a predetermined thickness or a lump of an appropriate size, the flat plate or It can be referred to as a method for producing a molded product using a shell piece composition composed of a process of cutting a lump into a shape according to the application and the above process.

    Similarly, the process of crushing the shells and selecting them so that the diameter or major axis is about 1 to 8 mm, preferably around 5 mm, and occupies the majority, and the entire perimeter of the selected shell crushes A process of forming a large number of flat shell shell pieces by performing a smooth molding process with a shaping machine on a peripheral shape over a range, addition of an appropriate amount of a curing agent and a curing accelerator, and a kneaded binder made of an appropriate synthetic resin with a resin weight of 10 A process of mixing and mixing rock wool or glass wool equivalent to 30%, a large number of flat shell shell pieces, either alone or as a mixture with an appropriate amount of low water-absorbing mineral particles as a filler, Appropriate amount of binder mixed with rock wool or glass wool is added, the quality and size of flat shell pieces, the quality and amount of extender, and the quality and amount of binder to be used, The kneading time is adjusted according to the type and ratio of the curing agent and curing accelerator to be added to this, and most of the flat shell shell pieces have a posture in which the flat surface is the same as the kneading direction or inclined in that direction.

Also included are a solidifying step and a method for producing a molded article by the shell piece composition comprising the above steps.

    The shell piece composition of the present invention having the above-described configuration is arranged in substantially the same direction by mixing the flat shell pieces with the respective flat surfaces in the same direction or those inclined in that direction. The whole vertical cross-sectional structure is formed as a torn joint, and the plane shape is not necessarily constant from a circle or ellipse to a distortion close to it, although the size is within a predetermined range. Fortunately, it is a flat shell piece, and the stacked structure realized by them is firmly bonded by a binder at or near the part where each shell piece directly abuts (this bonding structure is also the quality of the binder). It depends on the amount and amount, type and ratio of curing agent and curing accelerator added to it, and kneading time.) When an appropriate amount of low water-absorbing mineral particulates is added to the boundary part or as an extender, the so-called torn joints (in other words, the gaps remaining without being filled with them are not aligned vertically) Since it has a structure that stacks and overlaps in a zigzag shape or an Amida lottery shape), the fine gaps that are complicatedly connected in the vertical direction become capillaries, and rainwater has a complicated path both vertically and horizontally Therefore, freezing does not occur because water does not accumulate on the surface even in winter, and the continuous porosity is 10% even if it is small. It is possible to secure a certain degree of elasticity, and it has moderate elasticity and sound absorption effect. In the heat insulation effect, the thermal conductivity is 0.4819 (kcal / mh ° C), which is almost the same as water, and is about the same as that of asphalt. 1/2 Etc. become values have very soo features.

    In addition, the method for producing a molded article by the shell piece composition included in the present invention is such that the shell or shell is crushed and selected to have a diameter or major axis of about 1 to 8 mm, preferably about 5 mm of which is the majority. In addition, depending on the application and handling workability, a process of manufacturing a large amount of flat shell pieces by incorporating a process of smoothly forming the edge shape over the entire circumference of each contour, and the quality and size of the flat shell pieces Adjust the kneading time according to the quality and quantity of the filler, the quality and quantity of the binder to be used, and the type and ratio of the curing agent and curing accelerator to be added. The unique process called the process can surely produce the molded product of the shell piece composition of the present invention efficiently and expect the effect of stabilizing the quality. It has become.

    In implementing the present invention having the above-described configuration, the best or desirable mode will be described. First of all, shells made into flat shell pieces are natural, aquaculture, relatively small things such as swordfish, clams, clams, scallops, oysters, abalone, tunae, etc. All shells such as bivalves, snails, oysters and other oysters that are hardly edible can be adopted, but the overall shape is almost flat and the shape is almost flat (cultured products are more prone to this, most of them are discarded In addition to the advantage of being easily crushed into materials with a diameter or major axis of about 1 to 8 mm, the quality and strength are relatively stable, and the shape is well-organized to some extent. Scallop shells are the most suitable among these shells because they are easy to handle as raw materials, and are disposed of in large quantities and urgently needed to deal with them.

    This flat shell piece may be used as it is after crushing and sieving to a predetermined size, but if it is crushed, it will leave a sharp crushing port around it, causing injury during the manufacturing process. In the process of filling and solidifying in the mold, there are inconveniences of scratching the mold during repeated work over many years, and when it is a molded product with a shell piece composition, In addition to the possibility of injuring the human body etc. at the acute angle part exposed on the outer peripheral surface, above all, in the work process of kneading these large quantities of flat shell pieces together with the binder described below, each flat shell piece The remaining sharp protrusions interfere with smooth kneading and cannot be homogeneously kneaded, or even if possible, it will take a long time. ,Special By a mechanical device (for example, a trade name “GAM11-5T” manufactured by GAM, USA), the entire shape of a flat shell shape piece that does not always have a constant flat shape, from a circular shape or an elliptical shape to a distorted shape close to the circular shape. It can be said that it is desirable that the edge shape is formed by a smooth molding process, and is processed and adopted so as to have a circular shape, an elliptical shape or a shape close to the circular shape as smooth as possible.

    In addition, the flat shell piece that has been smoothly molded in the edge shape as described above is solid. If you try to make a shell composition, it will be difficult to spread if you need it in large quantities, and if it is needed in large quantities, it will not be popular, so it will interfere with the function of the desired shell composition. It should be adopted as a mixture with fillers in an optimal range without any loss, the range should be at least 50% less by the shell piece composition, 50-85% It is most practical to cover the remainder with the appropriate amount of material, which will be described later depending on the purpose and application. A large number of shells that trouble, will be coming out the significance to adopt taking advantage of the economic benefits that it is waste.

    For the purpose of achieving the purpose of the shell piece composition of the present invention, the bulking material used for this purpose is mainly used as a substitute for what should be a shell piece, and it is accompanied by a coloring agent. In addition to its function, it can enhance, alleviate, or reduce strength, water permeability, elasticity, and other effects brought about by the shell piece composition of the present invention by adjusting its particle size and blending amount, and tear joints By interposing and solidifying between flat shell shell pieces that form a laminated structure stacked in a shape, it is possible to fulfill the function of creating a continuous void that further complicates the torn laminated structure. It should be equal to or more than that of shells and be made of minerals with low water absorption like shells, such as dredged sand, colored calcined dredged sand, colored glass, precious stones, , Amphibole, Pa Light Balloon, actinolite, natural rocks such as tourmaline or alumina hydroxide Higilite, and high-purity inorganic substance such as strontium aluminate can be employed.

    These mineral materials are used as crushed and selected granular materials. Examples of various mineral granular materials include colored calcined cinnabar (made by Shinto Porcelain Co., Ltd., trade name “Color Sand R-5” and other 25 Type), crushed glass (made by Ichikawa Oil & Fat Transport Co., Ltd., trade name “Glass Sand”, etc.) and natural ore grains (such as dredged sand made by Maruto Kiln Co., Ltd. and sea sand made by Aomori Chemical Co., Ltd.) and others 1 or a combination of a plurality of types, and a particle size of about 30 to 70 mesh is preferable for realizing the shell piece composition of the present invention, but the structure of the target shell piece composition If the function is not hindered or special measures are taken so as not to hinder the function, it is not necessarily limited to this range, and a wider range can be selected.

    On the other hand, the binder is added to a mixture consisting mainly of the above-mentioned flat shell shell pieces and added with an appropriate amount of extender, and with the function of aligning them in a predetermined regulated laminated structure, the aligned laminated structure is fixed firmly. In addition to the photo-curable urethane synthetic resin, a composite resin composed of vinyl ester resin or polyester synthetic resin alone or in combination of two or three types can be used as a suitable solvent ( For example, urethane synthetic resins (for example, Toyo Polymer Co., Ltd.) that can be used with styrene monomers, acetone, xylene, etc., but have excellent weather resistance and are compatible with containers and packaging standards in the Food Sanitation Law. In addition to company-made product names “Polynate 97” and “Saffron 97”, manufactured by Nippon SSC Co., Ltd., product name “KBK NY-1”, Showa No matter what purpose and use the shell chip composition of this invention is used for any purpose or application, the use of the product name “SG1000” manufactured by Molecules Co., Ltd. does not contain harmful substances, and therefore has water permeability. It does not cause any problems if it is contaminated with water or comes into contact with the human body, and it is harmless and harmful to the environment even if they are used and become waste. It can be said that it is preferable.

    The synthetic resin is used to effectively act as a binder, and as is well known, a curing agent (for example, benzoyl peroxide manufactured by Nippon Oil & Fats Co., Ltd., trade name “Nyper FF”, Yakuzo Co., Ltd., trade name “328E” and curing accelerators (for example, Showa High Polymer Co., Ltd., trade name “Cobalt Naphthenate”), which is optimal for the type of synthetic resin The optimum amount is used in consideration of the appropriate amount, that is, the expected strength, curing speed, and the degree of modification.

    In this way, each of the flat shell shell pieces having a predetermined blending ratio, or a mixture obtained by adding an extender thereto, a binder containing an appropriate amount of a curing agent and a curing accelerator added to a synthetic resin is added and kneaded. Accordingly, by continuing the kneading for the required time, the flat shell pieces will have a difference between the adhesive force acting on the flat surface and the adhesive force acting in the direction perpendicular thereto, and gradually flat shell pieces Most of the postures are aligned so that each flat surface is in the same direction as the stirring direction, or those inclined in that direction are mixed in them, and curing is progressing in the kneading process. Since it gradually increases in viscosity and becomes a stringing state as when natto is stirred, it becomes an adhesive structure of those stringing states, so that the flat shell shell pieces are mutually in the same direction or in the same direction They are stacked so that the skein is mixed, and in the longitudinal cross section, it becomes a torn joint-like laminated structure, and in addition, the stretched material is interlaced with each other and the gap between them. Since an adhesive is present and a spot-like or linear bond is used rather than a planar bond, a complex gap structure is ensured while realizing a strong bond structure.

    This phenomenon, that is, the dot-like or linear adhesion structure due to the string-like adhesion, smoothly proceeds the phenomenon brought about by the hardening of the binder during the kneading process and gradually increases the viscosity, and further the adhesion. In order to increase the strength, the binder to be used is about 10 to 30% of the weight of the resin constituting the binder (if it is too small, the effect is difficult to appear, and if it exceeds the range, homogeneous stirring becomes difficult) In addition, the threading phenomenon of the adhesive is gradually reduced, and the adhesive strength is hindered.) It is extremely effective when used as a rock wool or glass wool mixed binder mixed with rock wool or glass wool corresponding to Was confirmed.

    Therefore, compared to those using a binder that does not mix rock wool or glass wool, the kneading time is greatly shortened and at the same time a homogeneous kneading state is ensured, each flat shell shell piece having a tear joint-like laminated structure, Or, they are mixed with various mineral particles as a filler in the form of a mixture, interposing as a part of the string-like binder and solidifying, so to speak, rock wool or glass wool is stringed. The core-like function of the adhesive (in other words, it can be said to be an adsorbent function) is achieved, and not only in the stirring process but also in the compression molding process in the mold, The binder sags downward and liquefies, making it impossible to maintain a point-like or linear adhesive structure in part, maintaining adhesive strength while maintaining complex voids. The desired structure of the present invention that to continue to, it can be assumed that there is no such thing as causing trouble to the realization of the shell pieces composition features.

    A number of flat shell pieces (flat pieces), which are important components of the shell piece composition of the present invention, or a large number of flat shell pieces (flat pieces) partly through an extender material realize a torn joint structure. Therefore, the manufacturing method requires special means, and the present invention includes these characteristic manufacturing methods, and in particular, effectively increases the viscosity of the binder and induces a reliable stringing phenomenon. In order to make sure that the optimum amount of curing agent and curing accelerator for the synthetic resin to be used as a binder is accurate, rapid metering, addition, and primary kneading to knead them, followed by a flat shell piece (flat piece) ), A low water-absorbing mineral powder as an extender that can be added in an appropriate amount as needed, taking into account its purpose, application, etc., as well as inducing the stringing phenomenon of the binder and preventing sagging in the compression molding stage. Role Over to a quantity of rock wool or glass wool, is weighed by a predetermined ratio, it can not be essential to the secondary kneading efficiently stirred with the kneaded and the binder is a kneader (mixer).

    In the kneader (mixer), due to the difference in the type, shape, size, specific gravity, etc. of the materials constituting the shell piece composition of the present invention, they are partially solidified or lifted up. It must be such that it does not interfere with homogeneous kneading, and an effective eccentric shaft mixer (for example, product name “HP 90L” manufactured by Kanto Blender Kogyo Co., Ltd.) is used for this purpose. Is desirable.

    In the process of automated kneading by these kneaders (mixers), the viscosity gradually increases with the progress of the curing of the binder with the elapse of a preset time in consideration of the room temperature and humidity. As the sticking strength is increased and forcible stirring is continued, the stringing phenomenon that occurs when natto is stirred gradually begins to occur, and this stringing phenomenon begins and the constituent materials Since the gaps between them are starting to form, it is easy for the movement of each component material to be influenced by the binder in the stringed state, but the adhesive force acting on the flat shell pieces (flat pieces) is applied to flat surfaces. Since the force increases far beyond that in the direction parallel to the flat surface (stirring direction), the posture of the flat shell piece (flat piece) is naturally adjusted with this stringing phenomenon. Since it will be possible to see a laminated structure in which each flat plane is in the same direction or slanted in the same direction, the process from this stringing phenomenon to the posture alignment situation is visually observed. Confirm and finish the second kneading process.

After that, it is properly molded so as not to oppose the direction of the arranged posture, and it is a direction to press the flat surface of the arranged flat shell piece (flat piece), and if it is compression-molded with a pressure according to the purpose and application, The shell piece composition of the present invention according to the purpose and application, or further processed by cutting or finishing the final kneading process and adjusting the posture, an appropriate plate to be used as a base, for example, an existing ALC plate, concrete plate, asphalt plate, gypsum board, etc. Molded to be placed on a molded plate or a molded body before reaching the molded plate, and compression molded in the same way to integrate both in the process, etc. Through the final process, the final target molded product is manufactured.
In the following, specific examples will be taken up in order to help grasp the configuration of the above-described shell piece composition of the present invention, the manufacturing method thereof, and the manufacturing method of the molded article thereby.

The example taken here is a flat shell piece (flat piece) that uses a scallop shell that is the remnant of edible shellfish (mostly cultured shellfish) and scallop shells that represent Japan. We will add specific explanations about the method.
First, scallop shell as the main ingredient (typical bivalve, usually the upper lid is a little reddish brown, the back lid is a pale yellowish white) or is exposed to rain water for a predetermined period, After washing together with water, the moisture content is adjusted to 20% or less by appropriate means such as thermal power or wind power, and then it is roughly crushed by a pulverizer. Shaped shell pieces 1.1. In addition, with the GAM11-5T crusher manufactured by GAM, USA, the edge shape over the entire circumference of each contour is as smooth as possible with a round, elliptical shape or a shape close to that. After processing, it is passed through a sieve, and a large number of those having a diameter or major axis of about 1 to 8 mm are prepared.

However, if it is used for a layer that is not exposed to the table, for example, a curing agent corresponding to the above vinyl ester synthetic resin. As a curing accelerator, the product name “Cobalt naphthenate” manufactured by Showa Polymer Co., Ltd. is used as a non-yellowing urethane synthetic resin heavy. Prepare in the range of 0.015 to 0.02% of the amount (determine the optimum value based on conditions such as temperature and curing time), and use the viscous liquid filling automatic meter (manufactured by Tokyo Mu Seiki Co., Ltd.) to optimize each. After mixing and mixing to blending ratio and kneading to be homogeneous as primary kneading, rock wool with a cut length of 3 to 5 mm and a fiber diameter of around 4μ (thermal conductivity 0.044 w / m · k, heat shrink temperature 700 ° C.) From the range of 10 to 30% of the weight of the non-yellowing urethane-based synthetic resin, mixed in an optimum proportion according to the purpose and application, and secondarily kneaded, and rock wool is uniformly dispersed and mixed And
For this kneading, an eccentric shaft mixer manufactured by Kanto Blender Kogyo Co., Ltd. and trade name “HP 90L” was employed.

    Subsequently, the scallop shell mixture prepared in advance in the rock wool mixed binder in the eccentric shaft mixer is mixed in a range of 95 to 90% with respect to 5 to 10% of the rock wool mixed binder. Then, as the viscosity of the binder increases and gradually becomes thread-drawn, the rotation speed from the first speed 72 (r / m) to the second speed 100 ( r / m), third speed 163 (r / m), and fourth speed 225 (r / m), and the third kneading is performed for about 4 minutes in summer and about 5 minutes in winter.

    After kneading in this way, most of the flat shell pieces 1.1. .. Is a flat shell shell piece prepared by quickly taking out the kneaded material in a state where the flat surface is the same as the kneading direction or inclined to the kneading direction. ...... It is spread out so that the posture is flat, and is formed into a flat plate of a predetermined thickness or a block of an appropriate size, and then a repetitive repetitive compressor (trade name “Fully Automatic 100t Type”, Yamazaki Tekko Co., Ltd. ) And then solidify by compression at a pressure suitable for the purpose and application, or after solidification, the flat plate or block is cut into a shape suitable for the application, or the kneaded material is quickly removed. After that, a molded product made of a desired shell piece composition is manufactured by covering and compressing and solidifying on a flat plate having a predetermined thickness or a block having an appropriate size.

    The molded product of the shell piece composition is as described above, and the longitudinal cross-sectional structure of the shell piece composition forming the basis thereof is shown in FIGS. 1 and 2 as a simulated structure. There is a flat shell piece 1.1. ...... There is one by itself, the one in Fig. 2 is a flat shell piece 1.1. ...... Predetermined proportion of colored calcined cinnabar 2.2. …… indicates the case of mixing and solidifying.
