Summary:The present invention relates to a thermoplastic resin composition, a method for manufacturing same, and a molded article comprising same. More specifically, provided is a thermoplastic resin composition comprising a base resin and polysiloxane in a predetermined composition ratio, the base resin comprising a vinyl cyan compound-conjugated diene rubber-aromatic vinyl compound graft copolymer, an alkyl acrylate rubber-vinyl cyan compound-aromatic vinyl compound graft copolymer, and an aromatic vinyl compound-vinyl cyan compound copolymer, wherein the alkyl acrylate rubber-vinyl cyan compound-aromatic vinyl compound graft copolymer has a graft rate of 42% or more and is included in an amount of 0.1 to 10% by weight with respect to 100% by weight of the total base resin. The thermoplastic resin composition not only has excellent colorability, but also exhibits a low clutch force, and at the same time has excellent dimensional stability against heat aging, thereby having an excellent clutch force retention rate. La présente invention concerne une composition de résine thermoplastique, son procédé de fabrication et un article moulé la comprenant. L'invention concerne plus particulièrement une composition de résine thermoplastique comprenant une résine de base et un polysiloxane selon un rapport de composition prédéterminé, la résine de base comprenant un copolymère greffé de composé vinylique aromatique-caoutchouc diénique conjugué-composé cyanure de vinyle, un copolymère greffé de composé vinylique aromatique-composé cyanure de vinyle-caoutchouc d'acrylate d'alkyle et un copolymère de composé cyanure de vinyle-composé vinylique aromatique, le copolymère greffé de composé vinylique aromatique-composé cyanure de vinyle-caoutchouc d'acrylate d'alkyle ayant un taux de greffe de 42 % ou plus et étant inclus en une quantité de 0,1 à 10 % en poids par rapport à 100 % en poids de la résine de base totale. La composition de résine thermoplastique présente non seulement une excellente aptitude à la coloration, mais présente également une faible force d'embrayage, et présente en même temps une excellente stabilité dimensionnelle contre le vieillissement thermique, ce qui permet d'obtenir un excellent taux de rétention de force d'embrayage. 본 발명은 열가소성 수지 조성물, 이의 제조방법 및 이를 포함하는 성형품에 관한 것으로, 보다 상세하게는 비닐시안 화합물-공액디엔 고무-방향족비닐 화합물 그라프트 공중합체, 알킬 아크릴레이트 고무-비닐시안 화합물-방향족비닐 화합물 그라프트 공중합체 및 방향족비닐 화합물-비닐시안 화합물 공중합체를 포함하는 베이스 수지에 폴리실록산을 소정의 조성비로 포함하며, 상기 알킬 아크릴레이트 고무-비닐시안 화합물-방향족비닐 화합물 그라프트 공중합체는 그라프트율이 42% 이상이고 상기 베이스 수지 총 100 중량%를 기준으로 0.1 내지 10 중량%로 포함되는 것을 특징으로 하는 열가소성 수지 조성물을 제공한다. 상기 열가소성 수지 조성물은 본 발명은 착색성이 우수할 뿐만 아니라, 낮은 클러치 포스를 나타내면서, 동시에 열 노화에 대한 치수 안정성이 우수하여 클러치 포스 유지율이 우수한 효과가 있다.
