Abstract

The invention relates to high-temperature-resistant electroplating-grade ABS resin and a preparation method thereof. The high-temperature-resistant electroplating-grade ABS resin is prepared from thefollowing components in parts by weight: 10-20 parts of ABS resin, 25-35 parts of ABS high rubber powder, 40-55 parts of highly branched styrene-acrylonitrile copolymer, 10-15 parts of heat-resistantagent, 0.1-10 part of kaolin and 0.5-2 parts of other auxiliary agents. Compared with the prior art, the high-temperature-resistant electroplating-grade ABS resin is obtained by controlling the content of the ABS rubber, compounding the rubber with large and small particle sizes and introducing the kaolin filler. The high-temperature-resistant electroplating-grade ABS resin prepared by the methodhas excellent high-temperature resistance and electroplating binding force, and the failure probability of an electroplated part in a cold and hot alternating experiment is reduced, so that the use requirements of electroplating-grade ABS in the fields of automobiles, household appliances and machinery are met.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-temperature-resistant electroplating-grade ABS resin and a preparation method thereof. Background technique [0002] Luxurious and beautiful is everyone's pursuit of the appearance of automobiles, home appliances and other products, while plastic electroplating parts give plastic a metallic appearance, making it more widely used. However, due to the difference in the linear expansion coefficient of the plastic and metal coatings by an order of magnitude, plastic electroplating parts are prone to problems such as coating bubbles, cracking of parts, and warpage and denaturation of parts after ambient temperature changes. High and low temperature resistance (-40°C ~ 100°C) chemical test is the most common method in the market to evaluate the coating adhesion of electroplated parts, and the test shows that high temperature has the greatest impact on the coating adhes...
