Abstract

The invention discloses a 30% mineral reinforced electroplating PC / ABS alloy material, wherein the components of the formula of the PC / ABS alloy material comprise: a PC resin, an ABS resin, an internal stress improver, modified mineral fibers, a toughening agent, a compatilizer, a lubricant and an antioxidant. The preparation method comprises the following steps: sequentially putting a main material PC, an ABS resin, an internal stress improver and a lubricant into a mixing mill, and mixing for 4-8 minutes to obtain a mixture; then adding a toughening agent, a compatilizer and an antioxidant into the mixture, and mixing for 6-10 minutes; adding the obtained mixture into the main feeding port of a double-screw extruder, adding modified mineral fibers into the side feeding port, and finallycarrying out extruding, water-cooling and granulating in the double-screw extruder. The obtained PC / ABS alloy material is small in residual internal stress, excellent in physical performance, good inelectroplating performance, low in preparation cost and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of preparation of engineering plastic alloy materials, in particular to a 30% mineral reinforced electroplating PC / ABS alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (hereinafter referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. It has rigidity, high transparency, high toughness, heat resistance and creep resistance, and has excellent dimensional stability. But flow processability is slightly worse. Acrylonitrile-butadiene-styrene copolymer (hereinafter referred to as ABS) is a thermoplastic polymer material structure with high strength, good toughness and easy processing, but its flammability and poor environmental resistance , lower heat distortion temperature, limiting its application. [0003] The inherent defects of PC and ABS affect the application in the industry. The PC / ABS alloy material is a thermoplas...
