Abstract

본 발명은 폴리에틸렌수지와 에틸렌-초산비닐 공중합체를 주재로 하는 합성수지 조성물에 불소계 탄성체인 비닐리덴 플르오라이드와 헥사 플르오로 프로필렌의 공중합체를 첨가하여서된 전선 피복재로서 우수한 성질을 갖는 새로운 합성수지 조성물에 관한 것이다.The present invention relates to a new synthetic resin composition having excellent properties as a wire coating material by adding a copolymer of fluorine-based vinylidene fluoride and hexafluoropropylene to a synthetic resin composition mainly comprising polyethylene resin and ethylene-vinyl acetate copolymer. It is about.

즉, 폴리에틸렌수지와 에틸렌-초산비닐 공중합수지로된 합성수지 조성물에 비닐리덴 플로오라이드와 헥사플르오로 프로필렌의 공중합수지를 0.03∼0.3wt% 혼합하여서된 전선 피복용 합성수지 조성물에 관한 것이다.That is, the present invention relates to a synthetic resin composition for electric wire coating, wherein a copolymer resin of vinylidene fluoride and hexafluoropropylene is mixed with 0.03 to 0.3 wt% in a synthetic resin composition made of polyethylene resin and ethylene-vinyl acetate copolymer resin.

본 발명에 따른 수지조성물은 가공성이 우수하고 기계적 성질과 인쇄성이 양호하며 특히 압출제품의 표면이 매끄러워 제품상태에서의 내환경응력 균열성이 개선되어 내구성이 요구되는 전선 피복재로서 적합한 특성을 갖게 된다.The resin composition according to the present invention has excellent processability, good mechanical properties and printability, and in particular, the surface of the extruded product is smooth, so that the environmental stress cracking resistance in the product state is improved to have suitable properties as a wire coating material that requires durability. do.
