Described oxidation inhibitor is the one in the compound of antioxidant 1010, antioxidant 1076, antioxidant 1010 or antioxidant 1076 and irgasfos 168.
Described lubricant is pentaerythritol stearate.
The preparation method of above-mentioned flame-retardant modified polycarbonate/polyethylene terephthalate, comprises the following steps:
(1), by PC in blast drier at 110 DEG C ~ 130 DEG C temperature dry 3 ~ 4 hours, PET at 130 DEG C ~ 150 DEG C dry 3 ~ 4 hours, stand-by;
(2), will take dried PC and PET by weight ratio adds in mixing machine, add compatilizer, fire retardant, impact modifier, photostabilizer, oxidation inhibitor, lubricant by weight ratio simultaneously, after to make to stir together 5 ~ 15 minutes all mixed, discharging adds in twin screw extruder carries out abundant melt blending, and extrude rear cooling, granulation by twin screw extruder, obtain flame-retardant modified polycarbonate/polyethylene terephthalate of the present invention.
The invention has the beneficial effects as follows, the present invention has PC, PET separately while advantage, also have excellent flame retardant properties, its limiting oxygen index(LOI) reaches more than 38%, and meets the flame retardant properties of Halogen, low cigarette, resistance to molten drop and UL94 V-0 level, and shock resistance is good, intensity is high, and ageing resistance is strong, and cost is low, wide adaptability, is easy to apply.
