Patent ID: 7981953

Claim:
A flame retardant rubber-modified styrene resin composition consisting of: A) 100 weight part of a rubber-modified styrene copolymer; wherein the rubber-modified styrene copolymer has such a structure that rubber polymer particles are dispersed in a matrix composed of a copolymer of a vinyl aromatic compound and compound copolymerizible with a vinyl aromatic compound; B) 3 ˜7 weight part of a non-halogen phosphoric ester compound as a flame-retardant wherein the non-halogen phosphoric ester compound is a triphenylphosphate, or an aromatic diphosphate represented by formula 1; and C) 0.5 ˜5 weight part of an aliphatic amide compound as a dripping enhancer, wherein the aliphatic amide compound is one or more compounds selected from the group consisting of stearamide, and ethylene bis stearamide, wherein the flame retardant rubber-modified styrene resin composition has flame retardancy of V-2 according to UL-94; wherein, Ar 1 ˜Ar 4 are phenyl or aryl with the substitution of 1 ˜3 C1 ˜C4 alkyl, R is phenyl or bisphenol A, and n is the degree of polymerization.
