폐폴리우레탄폼을 이용한 재생부재 및 재생부재 제조장치Recycling member and recycling device manufacturing apparatus using waste polyurethane foam
본 발명은 폐폴리우레탄폼을 이용한 재생부재 및 재생부재 제조장치에 관한 것이다. 더욱 상세하게는 폐폴리우레탄폼 제품을 다시 성형시켜 단열재 소재로 재생산함으로써, 폐폴리우레탄폼 폐기시 발생하는 대기오염을 줄여 공해가 발생하는 것을 방지하며, 폐폴리우레탄폼의 재사용에 따른 단열재의 원가를 절감할 수 있어 막대한 경제적 이득을 발생시키는 폐폴리우레탄폼을 이용한 재생부재 및 재생부재 제조장치에 관한 것이다.The present invention relates to a recycling member and a recycling member manufacturing apparatus using waste polyurethane foam. More specifically, by re-molding the waste polyurethane foam product and reproducing it as a heat insulating material, it reduces air pollution generated when the waste polyurethane foam is discarded, thereby preventing pollution, and the cost of the heat insulating material due to reuse of the waste polyurethane foam. The present invention relates to a recycling member and a recycling member manufacturing apparatus using waste polyurethane foam to generate enormous economic benefits.
일반적으로, 폴리 우레탄의 우수한 기계적 강도, 내 노화성, 단열성, 충격완충성, 불에 잘 타지 않는 재질로 더더욱 폭 넓게 사용되고 있고, 사용량이 늘어남에 따라 폐기되는 양 또한 한해 약 1만 5000ton이 폐기 소각되고 있으며, 폐기 소각되는 양 역시 매해 증가하는 추세이다.In general, polyurethane is widely used because of its excellent mechanical strength, aging resistance, heat insulation, impact resistance, and incombustibility.In addition, about 15,000 tons of waste are incinerated as the usage increases. The amount of waste incinerated is also increasing every year.
특히, 폐기되는 우레탄의 처리 비용이 예상외로 많이 소요되고 있으며, 소각 처리 과정에서 환경 유해 물질이 발생하여 환경오염을 일으키는 주된 원인이 됨은 물론, 대기권의 오존층이 파괴와 자연생태계의 교란시켜 지구와 전 세계인들을 병들게 하는 문제점이 있다.In particular, the cost of disposal of urethane is unexpectedly high.In addition, environmentally hazardous substances are generated during incineration, which is a major cause of environmental pollution.In addition, the ozone layer in the atmosphere is disrupted and disturbed by natural ecosystems. There is a problem that makes them sick.
이에, 최근에는 폐폴리우레탄을 이용하여 다양한 재생부재들을 생산하는 방법들이 개시되고 있으며, 대한민국 등록특허 제0424424호와 같이 폐폴리우레탄을 칩 상태로 생산하는 것을 특징으로 하는 폐폴리우레탄 수지의 재생 방법이 개시된 바 있다.Therefore, recently, methods for producing various recycled members using waste polyurethane have been disclosed, and a recycled polyurethane resin recycling method comprising producing waste polyurethane in a chip state as in Korean Patent No. 0424424. This has been disclosed.
하지만, 이는 단순히 폐폴리우레탄을 용융시켜 칩의 형태로 제조가 이루어지는 것일 뿐, 이를 활용하여 단열재나 보온재 등과 같은 건축용 소재로 활용하기 위해서는 재생산된 칩을 재가공이 이루어져야 만 하기 때문에 재생 공정에 소요되는 각종 비용이 상승할 뿐만 아니라, 재가공에 의해 제품이 생산된다 하더라도 이 제품의 연성을 저하시켜 고품질의 제품으로 생산이 어려운 문제점이 있다.However, this is simply manufactured by melting the waste polyurethane in the form of a chip, and in order to utilize it as a building material such as a heat insulator or a heat insulator, the remanufactured chip must be reworked. In addition to the increase in cost, even if the product is produced by reprocessing, there is a problem that it is difficult to produce a high quality product by reducing the ductility of the product.
이와 같은 문제점을 해결하기 위하여 본 발명은 폐폴리우레탄폼 제품을 다시 성형시켜 단열재 소재로 재생산함 으로써, 폐폴리우레탄폼 폐기시 발생하는 대기오염을 줄여 공해가 발생하는 것을 방지하며, 폐폴리우레탄폼의 재사용에 따른 고탄성, 고밀도의 단열재를 제조함에 따라 이 단열재의 원가를 절감할 수 있어 막대한 경제적 이 을 발생시키는 폐폴리우레탄폼을 이용한 재생부재 및 재생부재 제조장치를 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention is to re-form the waste polyurethane foam product to reproduce the insulation material, to reduce the air pollution generated when the waste polyurethane foam is disposed, to prevent the generation of pollution, waste polyurethane foam The purpose of the present invention is to provide a regenerated member and a regenerated member manufacturing apparatus using waste polyurethane foam which can reduce the cost of the insulator by producing high elastic and high density thermal insulator according to reuse.
또한, 본 발명은 폐폴리우레탄폼과 왕겨를 일정 비율로 혼합하여 재생제품으로 가공하고, 자연 건조 방식으로 건조가 이루어지도록 하여 에너지를 절감하는 한편, 왕겨 특유의 보온성, 난연성, 방사성 세슘 제거 등의 기능을 통해 친환경적인 단열재 또는 보온재로 제조할 수 있는 폐폴리우레탄폼을 이용한 재생부재 및 재생부재 제조장치를 제공하는데 그 목적이 있다.In addition, the present invention is to mix the waste polyurethane foam and rice husk in a certain ratio to process the regenerated product, and to be dried in a natural drying method to save energy, while removing the heat insulation, flame retardancy, radioactive cesium peculiar to chaff The purpose of the present invention is to provide a recycling member and a recycling member manufacturing apparatus using waste polyurethane foam which can be manufactured with environmentally friendly insulation or insulation.
