Even if we take one automobile, the number of automobiles that are no longer used is increasing year by year, and the discarded automobile parts are also industrial waste. However, the iron part that constitutes the skeleton of the automobile can be regenerated into iron again, but various interior materials, sound absorbing materials, sound insulating materials,
Many of the heat insulating materials and outer synthetic resin parts are merely industrial waste and are not recycled. The reason for this is that most of them use thermosetting resins or thermoplastic resins as raw materials, and recycling them requires a great deal of money, so they were not economically attractive.

Any industrial water that is used for industry can be used without problems. The thermoplastic fiber used in the present invention is 6-
Generally known fibers such as nylon, 66-nylon, polyethylene and polypropylene can be used. Fiber length is 2
Approximately 10 mm and a fiber having a thickness of approximately 1 to 10 denier are preferable because they have good dispersibility when mixed and dispersed.
From the viewpoint of the heating and melting temperature, polyethylene fibers are melted at a low temperature, which is preferable during production, but polypropylene fibers can also be preferably used. Examples of the thermoplastic resin used in the present invention include polyethylene resin, polystyrene resin, polypropylene resin, vinyl chloride resin, vinyl acetate resin, ethylene-vinyl acetate copolymer (EVA) resin, polyamide resin, polymethyl methacrylate resin, acrylonitrile. -Butadiene-styrene copolymer (ABS) resin etc. can be illustrated.

The thermoplastic resin and thermosetting resin exemplified above have various forms such as liquid, viscous body, powder and pellet form, but the resin usable in the present invention is insoluble or sparingly soluble in water. It is necessary. If it is soluble in water, it will be discharged together with water at the stage of dehydration after dispersion, and will not function as a binder.

Glass wool, rock wool, polyurethane foam,
They are so-called scrap products such as synthetic resin foam materials such as polypropylene foam, vinyl chloride sheets, synthetic resin sheet materials such as ethylene-vinyl acetate copolymer, and vibration damping sheet materials such as asphalt sheets. These scraps are finely crushed by conventionally known crushing means and used as raw materials. When the fiber component is ground, the fiber length when ground as a discontinuous fiber component is preferably about 2 to 10 mm, and more preferably about 5 mm. If the fiber length is less than 2 mm, it is difficult to obtain a sufficient density when producing a sound absorbing / insulating material as a recycled product, and if the fiber length is more than 10 mm, it is difficult to uniformly disperse in water. As a method for uniformly dispersing the crushed waste product in water, a conventionally known dispersing means such as a high-speed stirrer can be used.

This soundproof material raw material is passed through a heating and drying furnace, and each pulverized product in the soundproof material raw material is bonded by the resin component of the thermoplastic fiber, and residual water is removed. As described above, the binder component such as the thermoplastic fiber is heated by heating at 100 to 150 ° C. for about 15 to 50 seconds, whether it is heated and pressurized, or heated and dried while being sucked under pressure. Melt and adhere the dispersions to each other to function as a binder. In the case of a soundproof material fabric, if a thermosetting resin is used as the binder component, it needs to be in a semi-cured state. This is because it is necessary that the uncured binder component remains in order to obtain the molded soundproofing material by performing the heating and pressure molding with an arbitrary molding die in the next step. When thermoplastic fiber or thermoplastic resin is used as the binder component, it need not be particularly considered. It is also possible to manufacture the molded soundproofing material by a series of manufacturing processes by performing pressure suction dehydration and heat drying in an arbitrary molding die without passing through the stage of the original material of the soundproofing material. Molded soundproofing materials that can be produced according to the present invention include molded soundproofing parts for automobile dash insulators, dash outers, hood insulators, etc., molded ceiling materials for automobiles, parcel shelves, floor flattened cushioning materials, door trims, interior trim trims, etc. , Sound absorbing ceiling material for buildings,
A wall sound absorbing material, a heat insulating material and the like can be exemplified.
