Title (EN) IONIZING RADIATION RESISTANT THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE COMPRISING SAME
(FR) COMPOSITION DE RÉSINE THERMOPLASTIQUE RÉSISTANTE AUX RAYONNEMENTS IONISANTS ET ARTICLE MOULÉ COMPRENANT CELLE-CI
(KO) 내전리방사선성 열가소성 수지 조성물 및 이를 포함하는 성형품
Abstract:
(EN) A thermoplastic resin composition of the present invention is characterized by comprising: a thermoplastic resin containing a rubber-modified vinyl-based graft copolymer and an aromatic vinyl-based copolymer resin; a polyalkylene glycol; zinc oxide having an average particle size of about 0.5 to about 3 ㎛ and a specific surface area BET of about 1 to about 10 m2/g; and zinc phosphate. The thermoplastic resin composition and a molded article formed therefrom have excellent discoloration resistance, antibacterial properties, and acid resistance, even after exposure to ionizing radiation.
(FR) Une composition de résine thermoplastique selon la présente invention est caractérisée en ce qu'elle comprend : une résine thermoplastique contenant un copolymère greffé à base de vinyle modifié par un caoutchouc et une résine de copolymère à base de vinyle aromatique ; un polyalkylène glycol ; de l'oxyde de zinc présentant une taille moyenne de particules d'environ 0,5 à environ 3 µm et une surface spécifique BET d'environ 1 à environ 10 m2/g ; et du phosphate de zinc. La composition de résine thermoplastique et un article moulé formé à partir de celle-ci présentent une excellente résistance à la décoloration, des propriétés antibactériennes et une résistance aux acides, même après exposition à un rayonnement ionisant.
(KO) 본 발명의 열가소성 수지 조성물은 고무변성 비닐계 그라프트 공중합체 및 방향족 비닐계 공중합체 수지를 포함하는 열가소성 수지; 폴리알킬렌글리콜; 평균 입자 크기가 약 0.5 내지 약 3 ㎛이고, 비표면적 BET가 약 1 내지 약 10 m2/g인 산화아연; 및 인산아연;을 포함하는 것을 특징으로 한다. 상기 열가소성 수지 조성물 및 이로부터 형성된 성형품은 전리방사선 조사 후에도 내변색성, 항균성, 내산성 등이 우수하다.
