Problems solved by technology

However, since PC itself is not easy to be electroplated, generally speaking, the more PC content in PC/ABS, the worse the electroplating performance of the material
In order to improve the electroplating performance of PC/ABS materials, there is a patent report (CN101597782A) using N,N-dimethylformamide aqueous solution as an expansion agent, with MnO 2 /H 2 SO 4 It is a method of chemically microetching the surface of the material for the mi

Abstract

The invention relates to a platable polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) alloy material with high heat resistance and impact resistance. The alloy material comprises the following raw materials by weight percent: 20%-70% of PC (polycarbonate), 20%-75% of ABS (Acrylonitrile Butadiene Styrene), 2%-10% of butadiene type graft rubber, 0.2%-0.5% of calcium carbonate, 0%-1% of antioxidant and 0%-1% of lubricant. As butadiene type graft rubber MBS and calcium carbonate used as inorganic filler are added in the raw material formula of the PC/ABS alloy material, the electroplating performance of the material can be effectively increased while the material still has excellent mechanical properties, heat resistance and processability; and the material is easy to fill the large mould and can be used in the electroplating products in the vehicle and home appliance fields with higher heat resistant demands.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PC / ABS polymer alloy material with high heat resistance and high impact resistance, which can be electroplated. Background technique [0002] Polycarbonate (PC) plastic has the advantages of good transparency, high heat resistance, and good toughness; but it has poor fluidity, difficult molding, products are sensitive to gaps, prone to stress cracking, not resistant to solvents, and expensive. The above shortcomings are usually improved by preparing PC polymer alloys, and PC / ABS polymer alloys are the most common one. [0003] Acrylonitrile-butadiene-styrene graft copolymer (ABS) has the characteristics of good surface gloss, high mechanical properties, easy molding and processing, etc., and it has good spraying performance and electroplating performance. In actual production, the electroplating process is often used in the processing of ABS materials to make various...
