Abstract

The invention provides an electric-plated PC / ABS alloy and a preparation method thereof, wherein the electric-plating PC / ABS alloy includes the formula: 30-50 parts by weight of polycarbonate, 30-50 parts by weight of styrene-butadiene-acrylonitrile, 5-20 parts by weight of a high glue powder, 1-10 parts by weight of a compatilizer, 0-1 part by weight of an antioxidant and 0-1 part by weight of a lubricant. All the raw materials are stirred and mixed for 10-30 min in a mixing stirrer, the obtained mixture is sent into a double-screw extruder, the rotating speed of screws is controlled to be 160-300 rpm, melt extrusion and granulation are performed, and the electric-plated PC / ABS alloy is obtained. According to the prepared electric-plated PC / ABS alloy, by adjusting the ratio of PC and ABS, and adding a core-shell structure acrylic acid ester organic matter as the compatibilizer, the compatibility of PC and ABS is improved, and the prepared electric-plated PC / ABS alloy has more excellent tensile, bending and impact strength.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and relates to a PC / ABS alloy and a preparation method thereof, in particular to a PC / ABS alloy used in the field of electroplating and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is an engineering plastic with excellent performance. It has the advantages of outstanding impact toughness, wide service temperature range, good electrical insulation and dimensional stability, and is therefore widely used in the fields of automobiles and electronic appliances. a wide range of applications. However, PC has high melt viscosity, difficult processing and molding, especially large-scale products are prone to stress cracking, poor chemical resistance, and high price. These defects also limit its application in actual production. [0003] The performance of styrene-butadiene-acrylonitrile copolymer resin (ABS) is between engineering plastics and general-purpose p...
