<P>PROBLEM TO BE SOLVED: To provide a rubber-modified polystyrene-based flame-retardant resin composition and a molding in which the using for the application of an internal part, an exterior material or the like of OA equipment or a liquid crystal television, which receives thermal history over a long period of time is possible. <P>SOLUTION: The flame-retardant resin composition includes, based on (A) 100 pts.mass of a rubber-modified polystyrene resin, (B) 15-22 pts.mass of a bromine-based flame retardant of 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine, and (C) 2.3-3.7 pts.mass of an antimony trioxide. Further, the rubber-modified polystyrene-based flame-retardant resin composition comprises blending (D) 2,700-12,000 ppm of a phenolic antioxidant of octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate and/or triethylene glycol-bis [3-(3-t-butyl-5-methyl-4-hydroxyphenyl)propionate] as the addition concentration of the mass standard based on the whole flame-retardant resin composition into the flame-retardant resin composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
