Description

폐우레탄(폴리)을 이용한 반영구적 재활용 폴리 우레탄{omitted}Semi-permanent recycled polyurethane using waste urethane (poly)

본 발명은 폐폴리 우레탄을 가공하여 여러가지 재활용 폴리 우레탄 재품 생산(예, 조립식 판넬 내장재, 충격 보호재등)의 제작 방법에 관한 것으로, 현재 해마다 사용도가 증가하는 폴리 우레탄은 또한, 폐기 되어 지는 양 또한 늘어나는 추세이다.The present invention relates to a process for producing a variety of recycled polyurethane products (eg, prefabricated panel interior materials, impact protection materials, etc.) by processing waste polyurethane. It is an increasing trend.

폴리 우레탄의 우수한 기계적 강도, 내 노화성, 단열성, 충격완충성, 불에 잘 타지 않는 재질로 더더욱 폭 넓게 사용되어 지리라 생각된다. 사용량이 늘어남에 폐기되는양또한 한해 약 1만 5000ton이 폐기 소각(1ton ⇒ 200,000원)되어 지고 있으며, 매해 증가하는 추세이다.The excellent mechanical strength, aging resistance, thermal insulation, shock-absorption, and incombustibility of polyurethane are considered to be wider. As the amount of usage increases, about 15,000 tons of waste is incinerated (1ton ⇒ 200,000 won) per year, and is increasing every year.

본 발명은 많은 양의 폐 우레탄를 반영구적으로 재활용하는 것을 목적으로 하며, 현제 고안, 발명되고 있는것들은 여러가지 혼합물을 사용하거나, 고온을 이용하거나 하여, 재질 변화 및 반영구적 재활용에 차질이 차후 우려 된다.The present invention aims to semi-permanently recycle a large amount of waste urethane, and the presently devised and invented ones are concerned about material change and semi-permanent recycling later by using various mixtures or by using high temperature.

본 발명은 이런점을 보안한 발명이라 생각된다.The present invention is considered to be a secure invention.

폐 우레탄을 같은 성질의 약품인 P.T.301(플리에테르형의 플리우레탄플리폴리머용액)이라는 화공약품을 사용하므로 다시 똑같은 우레탄 재질로의 반영구적 폴리 우레탄 재활용 공법이다.Waste urethane is a semi-permanent polyurethane recycling method using the same chemical as P.T.301 (polyether type polypropylene polymer solution).

본 발명은 여러 가지 재활용도의 문제점을 개선하고, 우레탄의 우수한 기계적 강도, 탄성, 단열, 흡음, 불에 잘 안타는 특성을 이용한 반영구적 폴리 우레탄 재활용품 생산을 목적으로 한다.The present invention aims to improve the problems of various recyclability and to produce a semi-permanent polyurethane recycled product using the excellent mechanical strength, elasticity, heat insulation, sound absorption, and fire resistance of urethane.

지금 많이 사용되어지는 냉장고, 조립식 판넬(우레탄폼)등에 내장재로 사용되어지는 폐 폴리 우레탄은 해마다 대형화(냉장고)등등으로 생산 발생량이 늘어나는 추세이다. 위 폴리 우레탄 폐기물은 재활용은 시도하고 있으나, 실용화에 큰 난관에 부디쳐 있는 실정이며, 대부분의 폐 우레탄은 소각처리로 폐기처분 되어지도 있는 실정이다.Waste polyurethane, which is used as interior materials in refrigerators and prefabricated panels (urethane foam), which is widely used nowadays, is increasing in size due to the increase in size (refrigerator) etc. every year. The above polyurethane waste is being recycled, but it is a big challenge for practical use, and most of the waste urethane has been disposed of by incineration.

본 발명은 반영구적인 재활용을 할 수 있는 방법으로 본 발명의 생산단계는 다음과 같다.The present invention is a method that can be semi-permanent recycling is as follows production steps of the present invention.

폐 폴리 우레탄을 잘게 분쇄(지름 1∼2cm이하)하여, 폐 폴리 우레탄 분쇄품(약1㎥)와 화공약품(프리폴리머용액) P.T.301 (500㎖)을 분사식 혼합하여, 제품의 형틀에 (또는, 큰형틀 90cm×180cm×600cm) 분쇄품 혼합물을 압축(2∼5기압)한다. 압축된 형틀를 고온스팀(130℃이상)한다. (약5분이상) 고온스팀은 분쇄 혼합물의 약품이 분쇄품과의 균등분산과 접착력을 도와준다. The waste polyurethane is pulverized finely (1 ~ 2cm in diameter or less), the waste polyurethane crushed product (approximately 1m 3) and the chemicals (prepolymer solution) PT301 (500ml) are spray-mixed to the product mold (or, Large mold 90cm × 180cm × 600cm) The ground mixture is compressed (2 to 5 atmospheres). Compressed mold is hot steamed (over 130 ℃). Hot steam (more than 5 minutes) allows the chemicals in the grinding mixture to evenly disperse and adhere to the grinding product.

화학약품 프리폴리머용액(P.T.301)은 우레탄과의 화학적 성질, 재질이 같은 것으로 혼합물이 폐우레탄과 화학약품 프리폴리머용액(P.T.301)이므로 제품자체가 폴리 우레탄으로 보면 되며, 계속적인 반영구적 재활용 가능하다.Chemical prepolymer solution (P.T.301) has the same chemical properties and materials as urethane. Since the mixture is waste urethane and chemical prepolymer solution (P.T.301), the product itself is considered to be polyurethane, and it can be recycled semi-permanently.

여러 가지 가공, 형틀를 통하여 여러가지 제품을 생산할 수 있다.Various products can be produced through various processing and molds.

단열, 불에 타지 않는 성질, 흡음, 탄성 등의 장점을 이용한 건축, 생활용 제품등 여러방면에 사용가능하다.It can be used in various fields such as building and living products using the advantages of heat insulation, non-burning property, sound absorption and elasticity.

이 발명은 폐 폴리 우레탄의 여러가지 좋은 장점이 많이 있으나, 사용후 폐기되어야하는 커다란 단점 때문에 생활에 유용함에도 불구하고 사용이 꺼려져왔다. 허나 본 발명은 반영구적 재활용이 가능하다.This invention has many good advantages of waste polyurethane, but has been reluctant to use despite its usefulness in life due to the great disadvantage of being disposed of after use. However, the present invention can be semi-permanently recycled.
