Abstract

This invention relates to a formula for preparing flame-retardant PC/ABS alloy with high toughness by modifying recovered PC. The formula comprises: recovered PC 45-60 parts, ABS 20-35 parts, grafting monomer 1-5 parts, acrylate copolymer 3-10 parts, epoxy resin 0.1-1 part, antioxidant 0.1-0.5 part, bromine series flame retardant 6-12 parts, stibium series flame retardant 1-2 parts, inorganic flame retardant 1-2 parts, and polytetrafluoroethylene 0.2-0.8 part. This invention adopts high-efficiency compatibilizer to modify recovered PC and ABS and prepare PC/ABS alloy, thus can reduce the melt viscosity of PC and improve its processability, and is environmentally friendly due to resue of recovered PC.

Description

technical field [0001] The invention relates to the field of thermoplastic resin compositions in polymer material technology, in particular to a formula for modifying PC (Polycarbonate, polycarbonate) recycled materials into high-toughness flame-retardant PC (polycarbonate) / ABS alloys. Background technique [0002] PC is an engineering plastic with superior comprehensive performance. It has excellent impact toughness, dimensional stability, electrical insulation, creep resistance, weather resistance, transparency and non-toxicity. It is widely used in mechanical equipment, construction engineering, Transportation, instrumentation and electrical and electronic lighting and other fields. [0003] PC also has some obvious defects, such as: poor processing fluidity, easy stress cracking, sensitive to notch, easy to wear, poor chemical resistance, high price, etc. The consumption of PC is large, and at the same time, the amount of secondary materials, nozzle materials and recycl...
