[0005] At present, electroplating grade PC / ABS alloy products generally have the disadvantages of low electroplating bonding, low heat resistance and low electroplating yield.
Chinese invention patent 201310036468.1 "An electroplating PC / ABS alloy material and its preparation method" prepares the material, by reducing the content of butadiene (B) part or adding a heat-resistant agent to adjust the performance of the electroplating material, but reducing the butadiene The content will reduce the rubber phase that can be coarsened; adding heat-resistant agents will reduce the toughness of the material

Abstract
The invention discloses a high-fluidity electroplated PC (polycarbonate) / ABS (acrylonitrile butadiene styrene) alloy material and a preparation method thereof. The electroplated PC / ABS alloy materialwhich comprises, 30-55% of modified PC, 45-70% of styrene-butadiene-acrylonitrile copolymers, 1-10% of grafting copolymers and 1-10% of antioxidants. Si-PC powder and PC with molecular weight of 22000are blended and granulated to prepare the modified PC. The alloy material has the advantages that the Si-PC powder is introduced, so that siloxane molecules are coincided in polycarbonate, the flexibility of molecular weight of polymers can be improved, high fluidity of a PC / ABS copolymer alloy is increased, the flexibility of a molecular chain is increased, so that high fluidity of the copolymeralloy can be increased, internal stress of a product can be reduced in the subsequent machining process, electroplating performance is improved, corrosion resistance of Si is good, chemical resistance of PC framework materials is improved to some extent, and the impact resistance of the electroplated PC / ABS alloy material is improved.
Description
technical field [0001] The invention relates to the technical field of modified polymer materials, relates to the modification of PC / ABS materials, in particular to a high fluidity electroplating grade PC / ABS alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is an important thermoplastic engineering plastic developed in the late 1950s. It has excellent and balanced mechanical, electrical and molding properties. Its products are widely used in optics, electronic appliances, automobile industry, and mechanical properties. etc. However, PC has defects such as high melt viscosity, poor fluidity, easy high-temperature hydrolysis, poor corrosion resistance to organic solvents, general electrical insulation, and poor internal stress of the product. However, blending PC and ABS in a certain proportion to obtain ABS alloy can improve the performance of PC and broaden its application range. At present, PC / ABS has become a widely used a...
