Abstract
The present invention relates to a flame retardant styrene-based resin composition with high impact property. The styrene-based resin composition of the present invention comprises 1-30 parts by weight of a flame retardant, 0.5-15 parts by weight of a flame retardant aid and 0.1-15 parts by weight of a styrene-containing graft copolymer per 100 parts by weight of a base resin comprising a rubber-modified styrene-based copolymer and offers high impact property and good rigidity and fluidity, without appearance problem under a variety of processing conditions.
Claims10
A flame retardant styrene-based resin composition with high impact property comprising:
- 100 parts by weight of a rubber-modified styrene-based copolymer base resin;
- 1-30 parts by weight of a flame retardant;
- 0.5-15 parts by weight of a flame retardant aid;
- and
- 0.1-15 parts by weight of a styrene-containing graft copolymer,
- wherein the rubber-modified styrene-based copolymer base resin consists essentially of a matrix of polystyrene and a rubber polymer particle dispersed in the matrix of polystyrene;
- and the styrene-containing graft copolymer is a styrene-conjugated diene graft copolymer in which only styrene is grafted to 50 to 90% by weight of a conjugated diene rubber having an average particle diameter of 500-4000 Å, based on the total weight of styrene-conjugated diene graft copolymer.
