A kind of automobile-used PC/ABS alloys and preparation method thereof

The invention discloses a kind of automobile-used PC/ABS alloys and preparation method thereof, which is made of the raw material of following mass parts：Acrylonitrile butadient styrene：20~30 parts；Makrolon：70~80 parts；MMB methyl methacrylate butadiene styrol copolymer：4~6 parts；Compatilizer：6~8 parts；Fire retardant：8~12 parts；That resist warping agent：0.6~1 part；Antioxidant：0.2~0.4 part.Preparation method is as follows：First ABS, PC, MBS, compatilizer and fire retardant are dried, then each raw material is uniformly mixed, most afterwards through double screw extruder extrusion, pelletizing, drying, you can obtains automobile-used PC/ABS alloy granules.The automobile-used PC/ABS alloys of the present invention have excellent mechanical property and low temperature impact properties, and preparation method is simple, and the plank impact strength being prepared by it is high, flatness is good, without warpage, can be used as automobile board.
