Description

Inner panel and outer panel using useless composition fiber and useless vinyl and methode for manufacturing the same}

The present invention is made of various waste materials, namely waste synthetic resin and waste vinyl as main raw materials. The present invention relates to an exterior plywood and a method of manufacturing the same. More specifically, in the manufacture of internal and external plywood, a plywood made of closed plywood and waste vinyl is coated with a pigmented resin and used as a built-in plywood. Plywood mixes waste synthetic fiber and waste vinyl according to the resin content, heats and extrudes them, and compresses them, so that they have excellent tensile strength and strength, absorb or block chemical reactions by concrete, and have a light weight and beautiful surface. It relates to an interior and exterior plywood and a method for producing the same.

Conventional plywood is mainly made of wood plywood made by laminating the laminated wood on the plate, but this is due to the preservation of forests due to the protection of the natural environment, the supply shortage of wood is intensified to meet the demand will be.

Accordingly, recently, plywood made of a single material resin such as polypropylene (hereinafter referred to as PP) or polyethylene (BE referred to as BE below Polyethylene) has been developed, but it has a weak flexural strength and low external impact. When used for concrete formwork, it causes deformation of products due to chemical reactions and has a disadvantage of heavy weight.

In addition, the development of fiber plywood using waste synthetic fibers for the replacement of plywood made of only a single material of the wood plywood or PP or BE is in progress.

Thus, a method for manufacturing a plate using waste synthetic fibers is described in Korean Patent Publication No. 90-6296 (1990.8.28) and Patent Publication No. 92-21310 (1992.12.18).

Patent Publication No. 90-6269 relates to a method for producing a sheet material using waste synthetic fibers, the technical gist of which is supplied to the inside of the pressure roller by a pump of oil heated to 200 ℃ to 300 ℃ in a thermal medium boiler And pressurizing the waste synthetic fibers with this pressing roller to form a plate.

However, this method uses various kinds of synthetic fibers as a raw material, so that various synthetic fibers are press-molded only with a heating roller, so that product molding is incomplete or has problems such as plywood made of a single material resin.

In addition, the Patent Publication No. 92-21310 is primarily about 120 ℃ to 160 ℃ air while supplying the nylon and polyester surface between the other side of the supply of the upper and lower presses to a suitable thickness with a pressure roller It is heat-welded by heat to form a primary molded product, and it is a heat-compression roller having a heat of about 230 ° C to 260 ° C and heat-compressed at a pressure of about 100Kg / cm 2 based on the size of 10m / m. A solidified skin layer. The manufacturing method of the waterproofing plywood in which the cushion layer fusion | melted in the state of incomplete melt | dissolution between these skin layers was formed.

However, this method has a problem in that the bonding between the solidified skin layer and the cushion layer, which is an inner layer, may be peeled off, the strength against impact from the outside, and the shape may be easily changed.

On the other hand, a method for producing a fiber plywood by mixing waste fibers and synthetic resins such as waste vinyl, PP is disclosed in Korean Patent Application Publication No. 95-360 (1995.1.3) and the first invention patent application 94-19184 (1994.8.3) Described in the heading. Patent Publication No. 95-360 and Patent Application No. 94-19184 disclose a method of manufacturing a building fiber plywood by mixing waste fibers and waste vinyl (waste synthetic resin), spreading them into fine and uniform thicknesses, and then heating and joining them. to be. However, this method has the same problem as plywood made of only a single material resin such as waste fiber or waste vinyl, because the waste fiber and waste vinyl are both products made of synthetic resin.

The present invention has been made to solve the various problems described above, by mixing other waste materials in addition to the conventional waste fiber or waste synthetic resin, the weight is much lighter than the conventional gypsum plywood, but excellent in tension and incombustible By forming a similar foam layer in the interior plywood and product with abundant heat insulation and sound insulation, it absorbs or blocks the chemical reaction by concrete, and the weight of the product is lighter than the conventional fiber plywood, but the bending strength and phosphorus tension are excellent and the product processing It is an object of the present invention to provide an easy exterior plywood and a method of manufacturing the same.

The present invention in the manufacture of the interior plywood mixed waste natural fibers such as cotton, hemp and the like, poison, glass fiber, fire female material in a certain ratio to the main raw material mixed with waste synthetic resin and waste synthetic fibers, the exterior plywood is built-in plywood Instead of poison, glass fiber, and non-combustible materials used during manufacture, the mixture of poison (powder) and pulp (waste) is mixed, and after extrusion, the network sandpaper is squeezed, pressed and cooled. It is an internal / exterior plywood using waste materials and its manufacturing method.

Hereinafter, the manufacturing method of the present invention will be described in detail.

The product manufactured by the manufacturing method of the present invention is to be divided into plywood used as the exterior material of the building, and also plywood used as the interior material, when first manufacturing the plywood used as the exterior material is mixed waste synthetic resin and synthetic fiber snow 5070% by weight of the main raw material, 1020% by weight of waste natural fibers (cotton, hemp, etc.) and 2030% by weight of poison (stone) and pulp (waste), which are mixed with the main raw material, are extruded. Later, in the thermal roller crimping process, the net or the mesh cloth is squeezed and molded by extrusion. As the auxiliary material is mixed with the main raw materials, the flexural strength and tensile strength are much better than those of the plywood manufactured by the existing manufacturing method, and natural fibers, poisons, and pulp, etc. form a similar foam layer, thereby causing chemical reaction by concrete. It has been found to have the effect of absorbing or blocking the product, and also the weight of the product is light and easy to nail and saw on the plywood to give the user a familiar feeling like wood plywood as well as to have an excellent workability.

In addition, when manufacturing plywood for use as interior materials, 10 to 20% by weight of waste natural fibers (cotton, hemp, etc.) and 20 to 30% by weight of poisonous materials, glass fibers and non-combustible materials such as chemicals, etc. After mixing in a ratio, it is molded by an extrusion method by squeezing the net or mesh cloth in a compression roller process after extrusion.

The interior material manufactured in this way is much lighter than the plywood manufactured by the conventional manufacturing method, and the tensile strength is improved by about 5 times or more, and it is excellent in terms of bending strength as well as incombustibility, waterproofness, insulation and sound insulation. . In the present invention, the main raw material may be used singly as waste vinyl resin or waste synthetic fiber snow. In addition, in the present invention, the mixing of the waste natural fibers or fusion of the net or mesh cloth is to increase the tensile strength of the product, so each of them can be carried out at the same time or one of them can be selected and used as a poison material, pulp among the auxiliary raw materials of the exterior plywood. The wastes (paper waste) may be mixed with each other, or may be mixed with each other alone, and among the auxiliary raw materials of the built-in plywood, poisonous and glass fibers may be mixed with each other or may be mixed alone.

Conventional manufacturing method using a single material or synthetic resin only to melt the raw material 100% at a constant extrusion temperature to manufacture a product. The present invention sets the melting temperature to about 230 ℃ to 240 ℃ in the extrusion process by using a different melting method of the waste synthetic resin and waste synthetic fibers, each resin and fibers lower than its melting temperature is completely melted and liquefied, On the other hand, the high melting point of the fibers and the auxiliary raw material is extruded in the state of preserving the quality as possible.

At this time, the liquefied resin penetrates between the resin and the fiber having high melting point in the extrusion molding process, so even though the raw materials have different properties, all the raw materials are interconnected by the physical force extruded, so that the flexural strength and the tensile force are stronger than the existing products. will be.

In addition, in the conventional manufacturing method, the forming temperature of the product is usually 5-20 ° C., and is cold-formed depending only on the primary facility that is formed by the pressure roller. However, the product is first molded by a 120-150 ° C. heat roller. After the secondary molding by quenching with a pressure roller or a pressing press of 3 to 5 ° C or less, the pressing weight is much higher than that of a conventional press roller 3 to 10t and press 50 to 150t. By pressing at a pressure of 200 to 400 tons, the surface of the product is not only beautiful, but also the bending strength is doubled, and it is characterized by not being deformed at any temperature change.

In addition, in the attached manufacturing process diagram of FIG. 1, after the raw material extrusion, a plurality of stages of thermal rollers are joined, and the first molding is cooled. At the same time, the surface of the product was beautiful.

In addition, in the manufacturing process diagram of Figure 2 to eliminate the problems that may be caused by the characteristics of the raw material, each of the properties of the raw material by the first semi-processing, so that the second extrusion is smooth, the second extruded The dough raw material was pressurized with only 15-20 steps of heat and cold to form a product.

The characteristic of the manufacturing process shown in FIG. 3 is that all processes are automatically performed in one composite apparatus gas from the raw material mixer to the final process in which the finished product is produced, and thus, in the mold through two extrusion processes and one injection process. The product was allowed to mold.
