Flame Retardant ABS Resin Composition

난연성 아크릴로니트릴-부타디엔-스티렌 수지 조성물

Abstract

PURPOSE: Provided is a flame-retardant acrylonitrile-butadiene-styrene(ABS) resin composition comprising an ABS resin, a terminal sealed epoxy bromide compound, and a tin malate compound, which is excellent in weather resistance, heat stability, gloss property, and coloring property. CONSTITUTION: The ABS resin composition comprises: (A) 100pts.wt. of the ABS resin comprising a graft copolymer(a1) obtained by graft-polymerizing a rubber, selected from the group consisting of a butadiene rubber, an isoprene rubber, a copolymer of butadiene and styrene, and an alkylacrylate rubber, and a styrene monomer and an acrylonitrile monomer and a copolymer(a2) produced by copolymerizing the styrene monomer and the acrylonitrile monomer, wherein the ABS resin contains 10-20% of the rubber and 80-90% of the styrene-acrylonitrile copolymer; (B) 5-15pts.wt. of the terminal sealed epoxy bromide compound having a molecular weight of 500-3000 and represented by the formula (I), wherein n is 0 or a natural number; (C) and 0.1-1.0pts.wt. of the tin malate compound.
본 발명의 난연성 ABS 수지조성물은 (A) 부타디엔형 고무, 이소프렌형 고무, 부타디엔과 스티렌의 공중합체 또는 알킬아크릴레이트 고무로 이루어진 군으로부터 선택된 고무에 스티렌 모노머와 아크릴로니트릴 모노머를 넣어 그라프트 중합하여 얻은 그라프트 공중합체(a 1 )와 스티렌 모노머와 아크릴로니트릴 모노머를 공중합하여 제조한 공중합체(a 2 )로 구성된 ABS 수지 100 중량부; (B) 말단봉지형 브롬화 에폭시 화합물 5 내지 15 중량부; (C) 틴말레이트계 화합물 0.1 내지 1.0 중량부;로 이루어진다.
