Abstract
The invention relates to PC/ABS alloy, which mainly comprises the following components by weight part: 64 to 81 parts of polycarbonate (PC), 7 to 14 parts of acrylonitrile- butadiene- styrol copolymer (ABS), 2 to 5 parts of compatibility agents, 3 to 8 parts of toughening agents, 4 to 8 parts of phosphate ester anti flammability agents, 0.06 to 0.08 parts of sulfonate, 2 to 3 parts of siloxane mixtures, 0.2 to 0.5 parts of polytetrafluoroethylene, and 0.1 to 0.3 parts of antioxidant agents. The invention uses phosphate ester halogen-free anti flammability agent combined with little sulfonate anti flammability agent, thereby greatly reducing the use quantity of the phosphate ester anti flammability agents on the basis of keeping the anti flammability property being not changed. So the mechanical property of the PC/ABS alloy material is improved.
