Abstract

The invention relates to heat-resisting ABS (Acrylonitrile-Butadiene-Styrene) resin applicable to electroplating and a preparation method thereof. The heat-resisting ABS resin is prepared from the following ingredients in parts by weight: 0-30 parts of mass ABS resin, 20-40 parts of emulsion ABS rubber powder, 30-50 parts of styrene-acrylonitrile copolymer, 20-40 parts of heat resisting agent and 0.5-5 parts of other assistants, wherein the heat resisting agent is a quadripolymer based on four monomers including an N-phenyl maleimide monomer, an alpha-methyl styrene monomer, a styrene monomer and an acrylonitrile monomer, the weight percentage of the N-phenyl maleimide monomer is 5-20%, the weight percentage of the alpha-methyl styrene monomer is 40-70%, the weight percentage of the styrene monomer is 10-45%, the weight percentage of the acrylonitrile monomer is 10-45%, and the glass-transition temperature is 145-165 DEG C. According to the heat-resisting ABS resin applicable to electroplating and the preparation method thereof, through reasonably selecting the heat resisting agent, the heat resistance and plated layer binding force of the ABS resin are improved; and a heat-resisting master batch is not required to be prepared during preparation, so that the preparation is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a heat-resistant ABS resin suitable for electroplating and a preparation method thereof. Background technique [0002] Plastic electroplating products can not only achieve a good metal texture, but also reduce the weight of the product. It has unlimited potential in the automotive industry, which has increasingly high requirements for lightweight. ABS resin not only has excellent comprehensive properties and is easy to process and shape, but also the butadiene rubber in its components is easy to be eroded and can obtain high plating adhesion, so ABS resin is most commonly used in electroplating. However, the heat resistance and thermal stability of ABS resin are limited, and the test program of automobile parts has strict requirements for heat storage test and high and low temperature cycle test for automobile electroplating products. Insufficient heat resistance grade of the m...
