This invention is a flame resistant polycarbonate resin composition characterized by blending 0.01-2 weight parts of a silicone compound (B)) wherein a main chain has a branch structure and having an aromatic group in an organic substituent, 0.01-2 weight parts of an alkali metal salt of an aromatic sulfonic acid (C) represented by the following general formula 1 (hereafter, referred to as general formula 1), and 0.05-5 weight parts of a fiber-forming fluorine-containing polymer (D), relative to 100 parts of a polycarbonate resin (A): General formula 1: Am-R- (SO3M)n (wherein, R is a phenyl group, naphthyl group, or a phenyl group or naphthyl group substituted by A, where A is at least one type of substituent chosen from a group comprising a halogen atom, alkyl group, aryl group, vinyl group, alkoxy group, amino group, methyl ester group and ethyl ester group, and M is an alkali metal. Also, when R is phenyl, m and n are respectively the integers 0-5 and 1-2 (m+n ≦ 6), and when R is naphthyl, m and n are respectively the integers 0-7 and 1-2 (m+n ≦ 8).
The polycarbonate resin composition of this invention possesses superior flame resistance without losing shock resistance and moldability, and as it does not contain halogen fire retardants manufactured from chlorine and bromine compounds, there is no concern about generation of gases containing halogen from the fire retardant during combustion.
本发明是一种阻燃性聚碳酸酯树脂组合物,其特征是相对于 100 份的聚碳酸酯树脂 (A),掺入 0.01-2 重量份的有机硅化合物(B)(其中主链具有分支结构且有机取代基中 具有芳香基)、0.01-2 重量份的由以下通式 1 表示的芳香族磺酸的碱金属盐(C)(以下称 通式 1)和 0.05-5 重量份的成纤含氟聚合物(D):通式 1:Am-R-(SO3M)n(其中,R 是苯基、萘基或被 A 取代的苯基或萘基,其中 A 是至少一种取代基,选自由卤素原子、烷基、芳基、乙烯基、烷氧基、氨基、甲酯基和乙酯基组成的基团,M 是碱金属。此外,当 R 为苯基时,m 和 n 分别为 0-5 和 1-2 的整数(m+n ≦ 6);当 R 为萘基时,m 和 n 分别为 0-7 和 1-2 的整数(m+n ≦ 8)。
本发明的聚碳酸酯树脂组合物具有优异的阻燃性,同时不失抗冲击性和成型性,由于不含由氯和溴化合物制成的卤素阻燃剂,因此无需担心阻燃剂在燃烧过程中产生含卤素的气体。
