It contributes to maintaining the health of the human body and increases the tensile strength and the impact absorption due to the fiber of the plant. The present invention relates to a method for producing an economical composite composite board for reducing cost by using a waste material, preventing deformation due to cracking and shrinkage of a sheet, and utilizing waste resources.

Formwork used in the construction of conventional buildings mainly used plate-shaped wood, and as the demand gradually increases, the logging is increased, which seriously destroys the natural environment. Therefore, various regulations on environmental protection are being strengthened all over the world, and our country imports all of the wood from foreign countries, causing economic losses from the outflow of foreign currency.

Therefore, Patent Application No. 193-13092 discloses a method for manufacturing a form plate, and a method for manufacturing formwork for preventing surface cracking by adding some rubber, glass fiber and foaming agent to known polypropylene and polyethylene, It is not able to function to prevent adhesion of foreign matter to the surface, it is not able to function to strengthen the tension or impact absorption by environmentally friendly materials, it is not able to function to prevent deformation due to shrinkage, In addition, the formwork causes a bulging phenomenon in which the center becomes convex due to the pressure or load of the concrete during the curing process after placing concrete therein. When the formwork is removed after curing, the flatness of the building structure wall is deteriorated. do.

Also, if the formwork is removed from the cured building wall, the surface of the formwork has a lot of cement or other foreign matter, which makes it difficult to reuse.

In addition, these days, wall boards, ceiling boards, or floor boards used as interior / exterior materials for building have been mainly used in high-grade building materials decorated with veneer or synthetic wood with patterns or paintings. Although they are lightweight and widely used for building interior materials, they are chemically reacted as the concrete constructed in the building structure is cured, so the surface temperature rises to 80 ℃ depending on the season and place. There is a problem in that shrinkage, expansion and deformation are easy depending on the environment.

In addition, some interior resins were manufactured using synthetic resins as raw materials. However, these sheets have very high thermal expansion coefficients, which not only cause torsion after construction, but also increase the degree of expansion. I had a problem of weakness.

Therefore, not only wood or synthetic resin materials should be used for building interior and exterior materials, but also practical and economical aspects and recycling aspects of resources should be considered. There should be a way to collect various plastic products that are discarded due to development and fishing net ropes that are discarded in fishing villages and use them as interior / exterior plates for building.

Therefore, in order to solve the above problems, the present invention mixes and melt-extrudes waste vinyl, waste plastic, waste fishing net rope and environmentally friendly chaff, waste wood powder, rice straw powder, which causes severe environmental pollution, and forms a material mixture plate. By manufacturing a composite composite sheet with a PE resin melt layer on the upper surface and a PETE film layer on its surface, it is possible to replace imported plywood, which used to depend entirely on imports, as well as the number of times of use. It is economical because it collects and produces and uses all the wastes at the time of disposal, and it is economical, minimizing shrinkage and expansion by temperature and deformation by external force, and absorbing and cushioning shock to prevent damage by impact. Is to provide.

In order to achieve the above object, the present invention includes a granulation forming step of collecting the waste vinyl, waste plastic and waste fishing net rope to form granules by melt extrusion; A drying step of drying the chaff, waste wood powder and rice straw powder by a drying apparatus, respectively;

A first cutting step of cutting slightly larger; Forming step of building composite board for processing the first cut plate in cold storage device for 24 hours to prevent shrinkage due to temperature change, cutting it to actual dimension in finished product processing device and forming groove on the back It is characterized by.

Hereinafter, described in detail by the accompanying drawings as follows.

Figure 3a and Figure 3b is a process diagram showing a manufacturing method of the composite plate for building construction of the present invention.

The present invention is to provide a composite composite board that can be used as a formwork, ondol flooring, interior / exterior materials for building, in particular, it is easily discarded in the surroundings or farming and fishing villages, it has no useful value and is environmentally friendly waste resources and environmentally friendly It is to manufacture hygienic and economical building materials by recycling easily discarded materials.

In particular, it was manufactured using environmentally friendly data in the waste resources in consideration of the new house syndrome, which is a major social issue these days.

Therefore, the present invention is used to keep crops in rural areas, and then used for thermal insulation, discarded waste vinyl, or made of various household products, and used for various waste plastic products that have been disposed of due to end of life or damage, and used for fishing in fishing villages. Waste fishnet ropes, which are discarded or left untreated, are collected and melt-extruded at 180 ° C. to form granules.

The rice is milled to be mixed with the melt-extruded granules, and the discarded chaff is collected and dried by a drying apparatus, and the waste wood or sawdust, which is discarded in a wood or furniture factory, is collected and pulverized into waste wood powder through a grinder. After drying with a drying apparatus to remove moisture, harvested rice straw harvested and discarded in rural areas, crushed into rice straw powder and dried with a drying apparatus.

The specific gravity of the data is measured by a measuring device as waste vinyl 35%, waste plastic 10%, waste fishing net rope 15% and chaff 20%, waste wood powder 15%, rice straw powder 5%.

Weighing the specific gravity of the data to be mixed as described above is to optimize the tensile strength, impact absorption, sheet cracking, shrinkage deformation, etc. of building composite plates manufactured by many test results.

The specific gravity-measured materials are mixed and melt-extruded at 175 ° C. to form a data mixing plate 2 in the form of a rice cake.

Chaff, waste wood powder and rice straw powder, which are mixed vegetable materials, are inorganic fibers to increase tensile strength and impact absorption of waste plastics, waste plastics and waste fishing net ropes, and prevent cracking and shrinkage deformation of plates. In addition, the above data, which are plant components, are beneficial to the health of the human body and provide building materials mixed with synthetic resins while utilizing its properties.

Therefore, when the mixed materials are introduced into an extruder and melted at 175 ° C. and formed into a material mixed plate material having a predetermined thickness, the chaff, waste wood powder, and rice straw powder have different sizes of fibrous particles, so that the microcavity formed during the mixing process is appropriate. As it is adjusted and filled, it is extruded without the need for much pressure to form the material mixing plate 2.

The extruded sirutte-shaped material mixing plate (2) is passed through a primary roller, which is a cooling roller, to reduce deformation, and then cooled to a residual temperature of 115 ° C, followed by melting the PE resin at 175 ° C to extrude 0.2mm in thickness. The melted PE resin layer 3 is formed. Lowering the residual temperature of the material mixture plate 2 to 115 ° C in the primary forced roller is to reduce the deformation and to optimally extrude the PE resin melt layer 3 on the upper surface.

The reason for extruding the PE resin melt layer 3 to a thickness of 0.2 mm is to prevent the surface from being roughened by the chaff, waste wood powder, and straw straw powder mixed with the synthetic resin, and the PETE film layer on the surface of the building composite plate 1 This is to ensure that (4) is firmly fused.

 In addition, by supplying a PETE film having a thickness of 0.15 mm on the PE resin melt layer 3 formed by melting the PE resin at 175 ° C. and passing the second expansion roller, which is a thermal roller, the PETE layer 4 becomes ironed. This is strongly formed adhesive. At this time, the surface residual temperature of the material mixture plate 2 and the surface temperature of 175 ° C of the PE resin melt layer 3 are conducted to the melting point temperature of the PETE film layer 4, and the second expansion roller is forcibly heated. By closely adhering, the material mixture plate 2, the PE resin melt layer 3, and the PETE film layer 4 are integrally bonded.

Passing the third roller compaction roller, which is a heat roller once more, on the PETE film layer 4 is to reinforce the adhesive force, and passing the cooling roller device cooled by the coolant to the surface of the composite plate formed as described above. The purpose is to harden and smooth the surface so that cement or foreign matter does not stick to the surface.

Since the composite sheet is slightly stretched by heat, it is cut slightly larger than the actual dimension in the primary cutting device and stored for about 24 hours in a low temperature storage device to prevent shrinkage due to temperature change.

In the finished product processing device is cut to the actual dimensions and to form a cross groove (5) on the bottom surface to prevent deformation due to external temperature or pressure to complete the building laminate (1). Building plywood (1) completed as described above is shipped after packing in formwork, ondol flooring, building interior / exterior materials and the like depending on the application.

Building composite board (1) manufactured through the manufacturing method of the present invention is a predetermined plate shape of waste plastic 35%, waste plastic 10%, waste fishing net rope 15% synthetic fiber chaff 20%, waste wood powder 15% , 5% of straw straw powder is mixed and melt-extruded to increase tensile strength and prevent shock absorption, sheet cracking and shrinkage deformation transmitted from outside, and to shrink, expand and The grooves 5 intersected in all directions were formed on the bottom surface to maintain flatness without deformation.

In addition, a PE resin is melt-extruded on the upper surface of the material mixture plate 2 to extrude a 0.2 mm thick PE resin melt layer 3, and a 0.15 mm thick PETE film layer is formed on the surface of the PE resin melt layer 3. (4) After the formation, the surface is solid with a cooling roller device, the voting is delicate, clean, and smooth, so that cement or foreign substances do not easily stick, and when used as formwork, the structure is easy to be removed after construction. to be.

As described above, the present invention relates to waste plastics, waste plastics, waste fishing net ropes and environmentally friendly but discarded chaff, waste wood powder, straw straw powder, which cause environmental pollution when discarded. Building plate tends to be easily damaged by impact during manufacturing. Fiber chaff, waste wood powder and rice straw powder have a buffering effect to absorb shock, increase tensile strength, and have excellent thermal stability and thermoformability.
