Abstract

The invention provides an ABS (acrylonitrile-butadiene-styrene) material for electroplating, and a preparation method and application thereof. The ABS material for electroplating comprises the following components in parts by weight: 30-60 parts of common-emulsion-process ABS resin, 15-40 parts of high-flow-emulsion-process ABS resin, 2-10 parts of body-process ABS resin, 8-15 parts of high rubber powder, 6-12 parts of heat-resisting agent, 0.2-0.6 part of antioxidant and 0.5-1.5 parts of lubricant. The high-flow-emulsion-process ABS resin and body-process ABS resin are added to the ABS material for electroplating, thereby enhancing the flowability of the material, improving the processibility of the material, lowering the internal stress of the injection molding component, obtaining favorable electroplating binding force and enhancing the electroplating yield.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an ABS material for electroplating and its preparation method and application. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) is a polymer material with excellent comprehensive properties. Its composition includes butadiene rubber (PB). Obtain better bonding force, thus endow ABS material with good metallic texture. The ABS material after electroplating is widely used in various fields due to its good corrosion resistance, metallic luster, and beautiful appearance. [0003] At present, there are many reports on the technical research of ABS materials for electroplating. For example, the publication number CN103342864A provides a high-binding ABS resin for electroplating and its preparation method, and the publication number CN104004313A provides an ABS resin composition for electroplating. And its preparation method, the publication number is CN10...
