[0030] The PC resin, ABS resin, and various additives are added to the high-mixer and mixed at high speed for 2 minutes, then added to the main feeder of the extruder, and then added to the twin-screw extruder for basic granulation. The temperature distribution of the extruder is as follows: from the feed section to the die: 240℃, 260℃, 260℃, 260℃, 255℃, 250℃, 250℃, 250℃, 250℃, die head: 260℃ After the material is extruded, it is water-cooled, pelletized, and then packaged. The pellets were dried in a blast drying oven at 90°C for 4 hours, and then test specimens were prepared by an injection molding machine.

Abstract

The invention provides an electroplating PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) alloy material and a preparation method thereof. The electroplating PC / ABS alloy material comprises the following components in parts by weight: 30-70 parts of PC, 40-60 parts of ABS, 5-30 parts of styrene-acrylonitrile copolymer, 5-30 parts of butadiene graft rubber, 1-3 parts of compatilizer, 1-10 parts of heat-resistance modifier and 0.5-1 part of processing assistant. The alloy material provided by the invention has the advantages of favorable electroplating properties, excellent mechanical properties and favorable heat resistance, and can be used for designing automobile internal and external ornaments, including heat dissipation grids, door grips, vehicle logos, instrument panel decorating strips and the like.

Description

Technical field [0001] The invention relates to a PC / ABS alloy material 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 operating temperature range, good electrical insulation and dimensional stability. It has been used in the automotive and electronic and electrical industries. widely used. However, PC melt viscosity is high, processing and molding are difficult, especially large products are prone to stress cracking, chemical resistance is poor, and the price is relatively high. These shortcomings restrict the application of PC to a certain extent. The performance of styrene-butadiene-acrylonitrile copolymer resin (ABS) is between engineering plastics and general-purpose plastics. It has good impact resistance and processing performance, and the price is relatively cheap, so it has been widely used. However, its heat resistance a...
