Abstract

본 발명은 박리성이 우수한 외부 반도전 조성물에 관한 것이다. 본 발명은, 전력 케이블의 외부 반도전층으로서 베이스 주지로는 α-폴리올레핀 100 중량부를 사용하고, 그 첨가제로 도전성 카본블랙 20-70 중량부를 사용하며, 또한 필요에 따라서는, 산화방지제 0.3-2 중량부, 가공조제 1-15 중량부, 안정제 0.3-2 중량부, 가교제 0-4 중량부등을 사용하는 반도전 컴파운드 조성물에 에틸렌 공중압체 그라프트-폴리머를 0-50 중량부 첨가하는 특징으로 하는 전력 케이블용 박리용이 외부반도전 조성물을 제공해 준다.The present invention relates to an outer semiconducting composition excellent in peelability. In the present invention, 100 parts by weight of α-polyolefin is used for the base semi-conductive layer of the power cable, 20-70 parts by weight of conductive carbon black is used as the additive, and 0.3-2 parts by weight of antioxidant, if necessary. 0-50 parts by weight of an ethylene pneumatic graft polymer is added to a semiconducting compound composition using 1-15 parts by weight of a processing aid, 0.3-2 parts by weight of a stabilizer, 0-4 parts by weight of a crosslinking agent, and the like. Peeling for the cable provides an external semiconducting composition.
