TLDR
In this article, an electroplating pretreatment method for an acrylonitrile butadiene styrene (ABS) plastic surface was proposed, in which metal palladium activation is not used.Abstract:
The invention relates to an electroplating pretreatment method for an acrylonitrile butadiene styrene (ABS) plastic surface The electroplating pretreatment method comprises the following process steps of: eliminating stress, performing alkali washing for oil removal, pickling, roughening, performing neutralizing treatment, performing chemical activation, and performing the conventional electroplating, wherein in the chemical activation process, plastic base materials are put in to an activation solution and are subjected to hyperthermic treatment in a water bath for a certain period of time, each liter of the activation solution comprises 10 to 12g of nickel sulfate, 20 to 25g of sodium hypophosphite and 5 to 8g of sodium citrate, the pH is 9 to 11, and the temperature is between 70 and 75 DEG C In the invention, a novel method in which metal palladium activation is not used is provided, can be used for replacing a sodium borohydride and methanol activation process and contributes to environment friendliness; and on the basis of pretreatment, the plastic surface can be directly electroplated, so that the problems of complicated treating processes, high PdCl2 prices, high pollution possibility of a plating solution and the like are solvedread more
