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 great name is attached, it will not spread to the general public, and even if it is adopted meaningfully, shellfish growing in the sea will become a component of the cereal grain no matter how much it is washed When mixed with concrete resin or asphalt due to the material containing salt and porcelain, etc., it will weaken the solid strength due to the progress of oxidation and thermal expansion due to solar heat. The deterioration of the material strength due to the shrinkage difference included a fatal weakness that could not be avoided, and there was a grudge lacking in 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)
Based on the above awareness of the problem, the present invention has begun to develop and research it quickly from the judgment that effective utilization of the shell in accordance with the shell structure can solve the problems of conventional shell processing at once. As a result of repeating trial and error over many years and many trial productions and experiments, this time, we succeeded in finally realizing a shell structure with a novel structure and a method for producing a molded product therewith. In the following, the configuration will be described in detail together with an embodiment representative of the present invention.

(Structure of the invention)
The present invention is based on the composition of shellfish pieces, and basically comprises the following constitution.
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 Small pieces of cereal grains with a composition in which the 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 a thing.

    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 sorting shells, or a suitable amount of low water-absorbing mineral substance as a filler. In addition to the addition of granules, binders made of synthetic resin as appropriate make it possible for most of the flat shell shell pieces to have a flat surface in the same direction or a posture inclined in that direction to be mixed with them. By appropriately compressing and solidifying, the shell cross-section composition having a laminated structure in which the longitudinal section is broken and jointed is obtained.

    In this basic composition of the shell piece, a large amount of flat shell pieces obtained by crushing and selecting shells are added alone or as a bulking material with an appropriate amount of low water-absorbing mineral particles. Appropriate amount of binder made of appropriate synthetic resin to which curing agent and curing accelerator are added, and kneaded together with rock wool or glass wool corresponding to 10 to 30% of the resin weight and added between the flat surfaces of the flat shell shell pieces. Due to the difference between the adhesive force and the adhesive force in the direction parallel to the flat surface, most of the flat shell shell pieces are in the state where the flat surface is the same as the kneading direction or inclined in that direction. And includes a composition of shellfish pieces that are suitably 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 made by solidifying shells grain pieces composition.

    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, KaiKoku 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 said to be a shellfish piece composition that is aligned, compressed and solidified as appropriate.

And it relates to the above-mentioned shell grain piece composition, and 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.

Also included is a method for producing a molded product using a shellfish piece composition comprising the steps of solidifying and the above steps.

    The composition of the present invention having the above-described composition is composed of flat shell pieces that have the same flat surface in the same direction, or are mixed in a substantially inclined direction. The entire longitudinal cross-sectional structure is formed as a torn joint, and the plane shape is always constant from a circle or ellipse to a strain close to it, although the size is within a predetermined range. Fortunately, the stacking structure realized by them is firmly bonded by a binder at or near the part where each individual shell piece directly abuts (this bonding structure is also It differs depending on the quality and quantity, the type and ratio of the curing agent and curing accelerator added to it, the kneading time, etc.). 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 product by the composition of small pieces of shell cereal 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 among them.

    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 shell piece may be used as it is by sieving after crushing to a predetermined size, but if it is crushed, it will leave a sharp crushing port around it and cause injuries during the manufacturing process. In the process of filling and solidifying in the mold, there are inconveniences of scratching the mold during repeated operations over many years, and when the molded product is made from a small piece composition of shellfish Besides, it is assumed that the human body etc. may be injured at the acute angle part exposed on the outer peripheral surface, and above all, in the work process of kneading these large quantities of flat shell pieces together with the binder described below, individual flat shell pieces Since the sharp protrusions remaining on the hindrance prevent smooth kneading, uniform kneading cannot be performed, or even if possible, it takes a very long time. A 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 small composition of shellfish, it will not be popular if it is necessary in large quantities, and it will not be popular. It should be adopted as a mixture with an extender in an optimal range that does not come, the range should be such that the shell chip composition does not break at least 50%, From the range of 85% to the optimal ratio, preferably about 70%, and the remainder is covered by an appropriate amounting material as 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.

    In order to achieve the purpose of the composition of the present invention, the bulking material used for this purpose is mainly used as an alternative to what should originally be a small piece of shellfish. In addition to the function as a colorant, strength, water permeability, elasticity, etc. by adjusting the particle size and blending amount, etc. In addition, by interposing and solidifying between flat shell shell pieces that become a laminated structure stacked in a tear joint shape, it is also possible to fulfill the function of making the fracture joint structure a more complicated communication gap. , The strength should be equal to or higher than that of shells and should be made of minerals with low water absorption like shells, such as dredged sand, colored calcined dredged sand, colored glass, precious stones, , Amphibole Cristofano Pas light, 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 particle composition of the present invention. If there is no problem in the structure and function of the device, or if special measures are taken so that there is no problem, the present invention 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 shellfish piece 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. Even if the permeated water is contaminated or comes into contact with the human body, it does not cause any problems, and even if it is used and becomes waste, it is harmless and has an adverse effect on the environment. This 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, an appropriate amount of a curing agent and a binder added with a curing accelerator are appropriately added to the synthetic resin 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 like when natto is stirred, it becomes an adhesive structure of these stringing states, so the flat shell shell pieces are mutually in the same or the same plane They are stacked so that they are laid together, and in the longitudinal section, they have a torn joint structure, and they are thread-drawn at the parts where the fillers are in contact with each other and 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 by string-like adhesion, allows the binder to harden and gradually increase in viscosity during the kneading process, so that the adhesion proceeds more smoothly. 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 KaiKoku pieces composition features.

    A large number of flat shell pieces (flat pieces) or a large number of flat shell pieces (flat pieces) partly through a bulking material, which is an important component of the composition of the present invention, provides a layered structure with a torn joint. Therefore, the manufacturing method requires special means, and the present invention also includes these characteristic manufacturing methods, in particular, effectively increasing the viscosity of the binder and causing 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 kneading them, the primary kneading, followed by a flat shell shell piece (flattened) Small pieces), 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., and also triggering 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 differences in the type, shape, size, specific gravity, etc. of the materials constituting the shell chip composition of the present invention, they may partially solidify or float up to form the entire component material It must be such that it does not interfere with the 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. It is desirable to do.

    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.
