<p><P>PROBLEM TO BE SOLVED: To provide a styrene-based flame-retardant resin composition which ensures good creeping property, good mold releasability and well-balanced impact resistance strength, and to provide a toner cartridge container required to have self-extinguishing property by injection molding of the composition. <P>SOLUTION: The styrene-based flame-retardant resin composition contains 100 pts.mass of a rubber-modified styrene-based resin (A), 7-22 pts.mass of talc (B), 5-15 pts.mass of 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine (C), and 1-8 pts.mass of a flame retardant auxiliary agent (D). A content of a rubbery polymer in the flame-retardant resin composition is 3-6 mass%, and a component mass ratio of the rubbery polymer to the talc (B) is 0.22-0.45. In the rubber-modified styrene-based resin (A),≥70 mass% of the rubbery polymer is high-cis polybutadiene rubber containing≥90 mol% of cis-1,4 bonds. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
