Abstract

  The present invention relates to a manufacturing method and a molding apparatus for building floor noise shielding plate using waste fiber yarn separated from waste materials of automobile interior including waste tent, fire hose and farm water hose.

  Car interior sheets including tents, firefighting hoses, and agricultural waterway hoses that are currently produced in Korea are a large amount of waste (scrapers) are discharged during their production and altar processes.

  In the case of flooring, such wastes are composite PP, PE, PVC, etc., and their raising is nylon, PP, and polyester fiber yarns, and because they have different physical properties, they cannot be recycled without being separated. Since the separation is very difficult, most of them are incinerated or landfilled, so incineration causes air pollution due to soot and landfill due to oxidation.

  Patent No. 441835 and Patent Application No. 2005-81653, to which the present applicant has been applied, have been known to solve such problems, but they are suitable for use as a raw material of recycled material chips or plywood, but have weak elasticity and binding strength. There was a closed end that was not suitable as a noise blocking plate. On the other hand, floor noise barrier panels made of EVA sponge or polyester fiberfiber pressed or foam rubber are known, but this is a factor in the rise of construction cost due to the high price.

  The present invention has been invented to solve the above problems, the present invention is the suction fan (5-2) (7-2) of cotton-like short fiber yarn produced during the first and second crushing and the first and second separation process (2), feed roller (9-1), guide roller (9-2), feed roller (9-3) driven by a motor when suctioned into the extrusion process (9) through the fiber feed line (8). In the bonding and surface treatment process, the cotton-like extruded material is extruded into a sponge plate shape by the pinching roller 9-4, and the extruded sponge-like plate material becomes a noise blocking plate first. The backing paper 10-1 made of a nonwoven fabric wound on the lower winding roller 12 so that the nonwoven fabric LMD or the waterproofing cloth is thermo-compressed on the upper and lower surfaces while spraying the adhesive liquid with a sprayer is used as a pallet in the extrusion molding process. 10) to prevent deformation and breakage, and then to crimp and mark In the surface treatment step 13, the surface paper 10- is a non-woven fabric or a waterproofing cloth which is thermocompressed by the lower back pressing roller 13-2 to the backing paper of the pressing plate material 10a, and is unwound by the upper winding roller 12-1. 2) is made by the thermo-compression roller 13-2 at the top of the pressing and surface treatment process to be thermally compressed to the surface of the pressing plate (10a), and then cut to a certain size in the cutting process 14, binding and curability It is possible to produce products of durable noise-cutting plate at low cost.

In addition, since it is very difficult and economical to separate, most of it is incinerated or landfilled, so incineration causes environmental pollution such as air pollution due to soot and underground water pollution due to oxidation during landfill. There is a situation.

  In order to solve such a problem, the applicant's prior application patent No. 441835 has been known, but in recycling the waste sheet for automobile interior, the physical properties of the bottom layer and brushed layer of the sheet are separated to recycle short fibers and solids The patent application No. 2005-81653 filed by the applicant of the present application is to melt the fiber yarn contained in the solid material together with the solid material to form a building noise prevention sheet. It is suitable for recycled chip or plasterboard because of its high hardness and low elasticity, but it is not suitable as a noise barrier plate for building floor because of its weak elasticity and binding strength.

  On the other hand, there has been known a floor noise shielding plate made of EVA sponge or polyester fiber fiber or foam rubber sheet, but this is because the price is high and it is a defect that increases the construction cost.

  The present invention has been invented to solve the above problems, the present invention is to obtain a short fiber of 10mm or less by crushing and separating sheet waste for automobile or car interior by a known method with a tent or fire and agricultural water woven fabric synthetic fiber yarn Sponge through the feed roller (9-1), guide roller (9-2), feed roller (9-3), pinching roller (9-4) through the yarn feed line (8) After forming the formed plate member 10 and then transferring it to the pressing and surface treatment process 13, the surface of the molded plate member 10 is sprayed with the adhesive liquid sprayed from the adhesive liquid injector 11-1 installed at its inlet When passed into the drying chamber 13-1 in the state, it becomes a pressing plate material 10a pressed by a thermocompression roller 13-2 at 120 to 140 ° C, and a backing paper made of nonwoven fabric (LMB) on the back and the surface thereof ( 10-1) and the surface paper 10-2 made of nonwoven fabric or waterproof cloth are heat bonded. The backing paper 10-1 becomes the bottom pallet of the molded plate member 10 in the above-mentioned extrusion process 9 to prevent deformation and breakage of the molded plate member, and in the pressing and surface treatment process 13 in the drying chamber 13-1. Process of passing through the installed thermal pressing roller (13-2) Thermally bonded to the rear surface of the pressing plate material (10a) to the surface treatment and the surface paper (10-2) released from the upper winding roller (12-1) In the drying chamber 13-1, the thermocompression roller 13-2 is thermally bonded to the surface of the press plate member 10a to be surface treated, and then cut to suit the purpose in the cutting process 14, thereby binding and elasticity and It is possible to provide a building floor noise blocking material which is excellent in durability and harmless to human body.
