Abstract

본 발명은 열가소성 수지조성물에 관한 것이다. 본 발명은 내열성 ABS의 제조가공 중에 소량의 첨가제로 사용하여 내충격성을 그대로 유지하면서 내열성을 높여 내충격성과 내열성의 물성조화가 우수한 내열성 ABS수지를 제조하는데 목적이 있다. 본 발명은 α-메틸 스티렌 유니트와 아크릴로니트릴 유니트를 주성분으로 하는 랜덤 공중합체(성분(B)) 50 내지 80중량부와 아크릴로니트릴 부타디엔스티렌의 그라프트 공중합체(성분(A))가 20 내지 50중량부로 구성된 조성물 100중량부에 폴리디메틸 실록산(C)가 0.01-0.1중량부가 첨가되고 여기에 마그네슘 옥사이드(D)가 0.05-0.5중량부가 첨가되는 것을 특징으로 한다.The present invention relates to a thermoplastic resin composition. The present invention aims to produce a heat resistant ABS resin having excellent impact resistance and heat resistance properties while maintaining the impact resistance by using a small amount of additives during the manufacturing and processing of the heat resistant ABS. In the present invention, a graft copolymer (component (A)) of 50 to 80 parts by weight of a random copolymer (component (B)) having an α-methyl styrene unit and an acrylonitrile unit as a main component and an acrylonitrile butadiene styrene is 20 0.01 to 0.1 parts by weight of polydimethyl siloxane (C) is added to 100 parts by weight of the composition consisting of 50 parts by weight, and magnesium oxide (D) is added to 0.05 to 0.5 parts by weight.
