본 고안은 폴리에틸렌 발포수지제 의류에 관한 것으로서, 특히 내연성이 우수한 난연성 저밀도 폴리에틸렌 발포수지에 관한 것이다.The present invention relates to a garment made of polyethylene foamed resin, and more particularly to a flame retardant low density polyethylene foamed resin having excellent flame resistance.

일반적으로, 폴리에틸렌(Polyethylene)은 석유나 석탄에서 얻는 에틸렌을 중합시켜 만드는 합성수지로서, 열가소성을 가지고 있어, 가공하기 쉽기 때문에 다양한 용도로 널리 사용되고 있다.In general, polyethylene is a synthetic resin made by polymerizing ethylene obtained from petroleum or coal, and has been used in various applications because it has thermoplasticity and is easy to process.

특히, 상기 폴리에틸렌에 발포제를 첨가하여 부력성, 방한성 및 방수성을 가지도록 제조된 폴리에틸렌 발포수지는 특수용도의 의류, 건축자재 등에 사용되고 있다.In particular, the polyethylene foam resin prepared to add buoyancy, cold protection and waterproof by adding a blowing agent to the polyethylene is used for clothing, building materials, etc. for special purposes have.

폴리에텔렌 발포수지의 제조방법에는 여러가지가 있지만, 대한민국 특허 공고번호 제 91-5864에 개시된 내용을 예를 들어 설명하기로 한다.Although there are various methods for producing the polyetherene foamed resin, the contents disclosed in Korean Patent Publication No. 91-5864 will be described with an example.

특허공보에 개시된 바와 같이, 저밀도 폴리에틸렌, 발포제, 계면활성제 및 이형제를 혼합하여 가열실린더 내에 주입한 다음, 순차적으로 170℃에서 용융혼련하여 연화한 후, 200℃에서 발포를 촉진시키고, 150℃에서 비이드의 수축과 경화를 행한 후, 다시 기체 발포제를 주입, 재발포시킨 다음, 100℃의 온도에서 유지후 적당한 온도에서 압출시키고, 상온에서 방치하여 부분수축 및 비이드 조직을 경화시켜 제조하는 것으로 기술되어 있다.As disclosed in the patent publication, low-density polyethylene, blowing agent, surfactant, and release agent are mixed and injected into a heating cylinder, followed by melt kneading at 170 ° C. in order to soften, and then promote foaming at 200 ° C., and the ratio at 150 ° C. After shrinking and curing of the id, the gas blowing agent is injected and re-foamed again, and then maintained at a temperature of 100 ° C., extruded at an appropriate temperature, and left at room temperature to harden partial shrinkage and bead structure. It is.
