JPH09194716A - New raw material reclaimed from mixture of waste thermoplastic resin and waste urethane foam and product produced from the raw material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a reclaimable and reusable raw material by crushing, pulverizing and mixing (melting) a waste thermoplastic resin and a waste urethane foam and forming the mixture with a molding machine. SOLUTION: A melted mixture is produced by mixing (A) 20-99wt.% of a crushed and pulverized waste thermoplastic resin with (B) 1-80wt.% of a crushed and pulverized waste urethane foam and melting the obtained mixture by a volume-reducing machine. The crushed mixture may be produced from a melted waste thermoplastic resin. Waste materials can be reclaimed and reused to form various molded articles in place of incinerating or land-filling the waste.

Description

Detailed Description of the Invention

[Industrial field of application] [0001] This invention can be commercialized as a remanufactured product by mixing a thermoplastic resin as waste with urethane foam.

[Prior Art] Thermoplastic resins as waste were collected and reused and reused to a certain extent, but most of the waste thermoplastic resins were incinerated or crushed, and landfilled. Final disposal has been made.
On the other hand, waste urethane foam is also incinerated or crushed,
Final disposal such as landfill is done. In addition, waste thermoplastic resin and waste urethane foam will generate black smoke and toxic gas when incinerated, and shorten the life of the incinerator due to the high combustion temperature during incineration. Disposal of ash after incineration has also become a problem, and in particular, waste urethane foam is difficult to incinerate and there are many residues after incineration. For landfill disposal, securing a landfill site is also a problem because of the large capacity.

[Problems to be Solved by the Invention] The present inventor has studied in order to solve problems such as pollution caused by incineration of waste thermoplastic resin and waste urethane foam and land acquisition by landfill disposal. Layered.

[Means for Solving the Problem] As a result, in order to recycle and reuse the waste thermoplastic resin and the waste foamed urethane, the mixed raw material according to claim 1 is prepared, and the molding machine according to claim 2 is used. It was possible to commercialize.

[Operation] In this way, the thermoplastic resin as waste and the waste urethane foam become raw materials,
It can be recycled and reused as a product by a molding machine.

[0006]

[Example] In claim 1, the mixing ratio of the crushed / crushed waste thermoplastic resin and the crushed / crushed waste foamed urethane is 20 to 99% of the waste thermoplastic resin and 1% to 80% of the waste foamed urethane. Mix and mix to make ingredients. This is called a crushed mixed material. A melted waste thermoplastic resin may be used when preparing a crushed mixed material. Alternatively, the crushed mixed material can be melted in a volume reducer to make the material. This is called a melt mixed material. Then, the crushed mixed material is put into a molding machine to mold a molded product. Alternatively, the molten mixed material is put into a molding machine to mold a molded product. Further, it is well known that the waste thermoplastic resin can be molded alone, and it goes without saying that the virgin material can be specified for any mixing.

[Advantages of the Invention] It is possible to solve problems such as pollution caused by incineration of waste thermoplastic resin and waste foamed urethane and land acquisition by landfill disposal, and various molded products are manufactured by a molding machine. can do.

[Example] In claim 1, the mixing ratio of the crushed / crushed waste thermoplastic resin and the crushed / crushed waste foamed urethane is 20% to 99% of the waste thermoplastic resin.
%, Waste urethane foam is mixed at 1% to 80% to make a material. This is called a crushed mixed material. A melted waste thermoplastic resin may be used when preparing a crushed mixed material. Alternatively, the crushed mixed material can be melted in a volume reducer to make the material. This is called a melt mixed material. Then, the crushed mixed material is put into a molding machine to mold a molded product. Or, put the molten mixed material into the molding machine,
Mold the molded product. Further, it is well known that the waste thermoplastic resin can be molded by itself, and by mixing the virgin material, the quality of the molded product is improved in strength and elasticity.

Claims (2)

[Claims] 1. A crushed and crushed waste thermoplastic resin and crushed
The raw material for the molded product is made with a mixture of crushed waste urethane foam or a mixed melt. 2. A molded article is manufactured from the raw material produced in claim 1.
