Abstract

본 발명은 MI 1∼60인 폴리프로필렌수지 40∼80중량부, 에틸렌함량이 40∼85%의 에틸렌/프로필렌 공중합고무, 에틸렌 함량이 40∼85%의 에틸렌/프로필렌/디엔 3원 공중합고무 및 스틸렌/부타디엔계 공중합체로 이루어진 군으로부터 하나 또는 그 이상 선택된 고무성분 3∼25중량부, 평균입경이 0.5∼50㎛인 탈크를 필수적으로 함유하는 무기충전제 5∼45중량부 및 쵸프트스트랜드 형태로 직경이 10∼13㎛이고, 길이가 3∼13㎛인 유리섬유 2∼20중량부로 필수적으로 이루어진 폴리프로필렌 수지조성물에 관한 것이다. 상기 조성물은 높은 굴곡탄성율, 내긁힘성, 내열변성 및 충격강도 등의 우수한 물리적특성을 가지며, 동시에 낮은 성형수축율과 우수한 성형흐름성을 가짐으로써 중소형의 전기전자부품을 비롯하여 자동차용 대형사출물에 이르기까지 적용이 가능하며 기존의 폴리스티렌 또는 아클릴로니트릴/부타디엔/스틸렌 공중합체의 대체용도에의 일부 적용도 가능한다.The present invention relates to a rubber composition comprising 40 to 80 parts by weight of a polypropylene resin having an MI of 1 to 60, an ethylene / propylene copolymer rubber having an ethylene content of 40 to 85%, an ethylene / propylene / diene ternary copolymer rubber having an ethylene content of 40 to 85% / Butadiene-based copolymer, 5 to 45 parts by weight of an inorganic filler essentially containing talc having an average particle diameter of 0.5 to 50 μm, and 5 to 45 parts by weight of a rubber component having a diameter Of 10 to 13 占 퐉 and a length of 3 to 13 占 퐉 and 2 to 20 parts by weight of glass fiber. The composition has excellent physical properties such as high flexural modulus, scratch resistance, heat resistance modification and impact strength, and at the same time has a low mold shrinkage ratio and excellent molding flowability, so that it can be applied to small and large electric and electronic parts, And some applications to alternative uses of conventional polystyrene or acylonitrile / butadiene / styrene copolymers are possible.
