Abstract

본 발명으니 폴리프로필렌수지조성물에 관한 것으로, 보다 상세하게로는 무기질 분체 또는 섬유질을 함유한 스피커 진동체용 폴리프로필렌 수지조성물에 관한 것이다.The present invention relates to a polypropylene resin composition, and more particularly, to a polypropylene resin composition for a speaker vibrator containing inorganic powder or fiber.

이 발명은 폴리프로필렌 수지 60-98 중량%와 흑연분말, 카본섬유, 흑연섬유 중에서 선택된 1종 이상의 충전재 2-40 중량%로 구성된 조성물에, 폴리프로필렌 수지 100중량부에 대하여 비결정화 핵제 0.1-1중량부가 사용됨으로써, 본 발명에 의한 복합수지체는 일반적인 사출기만으로 매우 단순하게 성형할 수 있어 진공성형에 비교하여 재료 손실이 발생되지 않을뿐 아니라 펄프형에 비하여 획기적인 인력절감을 할 수 있다.The present invention is a composition consisting of 60-98% by weight of polypropylene resin and 2-40% by weight of at least one filler selected from graphite powder, carbon fiber and graphite fiber, and 0.1-1 amorphous nucleating agent with respect to 100 parts by weight of polypropylene resin. By the use of the weight part, the composite resin according to the present invention can be molded very simply by a general injection machine, so that no material loss is generated as compared to the vacuum molding, and it is possible to reduce the manpower significantly compared to the pulp type.
