Zusammenfassung: | The present invention relates to a halogen-free flame retarding resin composition having improved leading-in properties and an insulated electric wire using the halogen-free flame retarding resin composition. More specifically, the present invention relates to the halogen-free flame retarding resin composition which is environmentally friendly, and has excellent flame retardancy and mechanical properties and improved leading-in properties since the composition does not comprise halogen and has a low friction coefficient, and the insulated electric wire using the halogen-free flame retarding resin composition. The halogen-free flame retarding resin composition of the present invention comprises: a base resin including a polyethylene resin and a polyolefin-based elastomer; a non-halogen based flame retardant; a crosslinking agent; metal stearate; and fatty acid amide, wherein the polyolefin-based elastomer, as a copolymer of ethylene and α-olefin having 3 or more of carbon atoms, is obtained by mixing a first polyolefin-based elastomer having a melt index of 1.0 to 2.0 g/10 minutes with a second polyolefin-based elastomer having a melt index of 3.0 to 4.0 g/10 minutes.
본 발명은 인입성이 향상된 할로겐프리 난연성 수지 조성물 및 이를 이용한 절연 전선에 관한 발명에 관한 것으로서, 더욱 상세하게는 할로겐을 포함하지 않아 친환경적이면서 난연성 및 기계적인 물성이 우수하고, 마찰계수가 낮아 인입성이 향상된 할로겐프리 난연성 수지 조성물 및 이를 이용한 절연 전선에 관한 발명이다. 본 발명의 인입성이 향상된 할로겐프리 난연성 수지 조성물은 폴리에틸렌 수지와 폴리올레핀계 엘라스토머를 포함하는 베이스 수지, 비할로겐계 난연제, 가교제, 금속 스테아레이트 및 지방산 아미드를 포함하며, 상기 폴리올레핀계 엘라스토머는 에틸렌과 탄소원자가 3 이상인 α-올레핀의 공중합체로서, 용융지수가 1.0~2.0g/10분인 제1 폴리올레핀계 엘라스토머와, 용융지수가 3.0~4.0g/10분인 제2 폴리올레핀계 엘라스토머를 혼합한 것을 특징으로 한다. |
