An antistatic LSZH pc / abs alloy material and preparation process

The present invention is in the field of functional plastic alloy material, in particular discloses a halogen-free flame retardant antistatic PC / ABS alloy material and its preparation process. The alloy material containing 55 to 75? wt% of PC (polycarbonate), 25 to 45? wt% of ABS (acrylonitrile - butadiene - styrene graft copolymer), 10 to 40? wt% of a flame retardant, 2.5 to 10? wt% of a synergist agent, 0.5 ~ 2? wt% of an antistatic agent, 0 to 5? wt% compatibilizer, 0 to 0.5? wt% coupling agent, 0 to 0.5? wt% of a dispersing agent, 0 to 0.5? wt% antioxidant. According to the above formulation Weigh the raw material mixed by high speed mixer, and then pelletized material extruded by a twin-screw extruder. Used in the present invention has a new inorganic flame retardant non-halogen, low smoke, non-corrosive, non-toxic, good flame retardancy, thermal stability, had little effect on mechanical properties, etc., the UL94 flame performance can be achieved? V-0. As used in the present invention has high antistatic agents, non-toxic, and environmentally friendly, the surface resistivity of the alloy material reaches 106 ~ 1016Ω, and good long-term antistatic properties.
