(57) [Summary] (Correction) [PROBLEMS] To provide a flame-retardant styrene-based resin composition having a small amount of silver strike and an excellent heat stabilizing effect. SOLUTION: By adding 0.01 to 5.0 parts by weight of calcium hydrogen phosphate to a flame-retardant styrene resin composed of 100 parts by weight of styrene resin and 1 to 50 parts by weight of bromine flame retardant, silver -A flame-retardant styrene-based resin composition with less stroke is obtained. Furthermore, at least one compound selected from hydrotalcite, zinc-substituted hydrotalcite, A-type zeolite, and zeolite containing a metal of Group II or IV of the periodic table is added to this in an amount of 0.01- By adding 5.0 parts by weight together, a flame-retardant styrene-based resin composition having further excellent thermal stability can be obtained. |
