Reinforced ABS resin composition suitable for electroplating, and preparation method and application thereof

Abstract

The invention discloses a reinforced ABS resin composition suitable for electroplating. The composition comprises 85-96wt% of an ABS resin, 3-10wt% of a carbon fiber, 0.1-1.0wt% of a dispersant, 0.01-1.0wt% of a lubricant, 0.1-1.0wt% of a main antioxidant and 0.5-2.0wt% of an auxiliary antioxidant. The reinforced ABS resin composition suitable for electroplating can reduce the linear thermal expansion coefficient of a plastic electroplating product, has an above 50% lower linear thermal expansion coefficient than a common ABS resin, and can well meet the performance requirements of the plastic electroplating product. The adoption of the carbon fiber enhances the conductivity of the ABS resin, effectively increases the bonding force between the ABS resin and an electroplating layer, shortens the pretreatment time of electroplating, improves the electroplating production processing efficiency, and is in favor of the electroplating production. The reinforced ABS resin composition suitable for electroplating has high mechanical strength and good dimensional stability.

Description

technical field [0001] The invention relates to the field of macromolecules, in particular to a reinforced ABS resin composition suitable for electroplating, a preparation method and application thereof. Background technique [0002] In recent years, plastic electroplating has been widely used in the decoration of plastic parts, and ABS plastic is the most widely used one in plastic electroplating parts. ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S). For electroplating-grade ABS plastics, the content of butadiene has a great influence on electroplating, and generally should be controlled at 18% to 23%, and the binding force with the electroplating layer is the best. However, since ABS plastic is a non-conductor, a conductive layer must be attached to ABS plastic before electroplating, which requires several steps such as roughening, neutralization, sensitization, activation, and electroless plating, and the processing process is relatively...

Problems solved by technology

However, since ABS plastic is a non-conductor, a conductive layer must be attached to ABS plastic before electroplating, which requires several steps such as roughening, neutralization, sensitization, activation, and chemical plating, and the processing process is relatively complicated.

In addition, due to the low rigidity of ABS plastic, for some plastic electroplating parts with high mechanical strength requirements, such as electroplated car door handles and TV support bases and other plastic electroplating parts, it is difficult for ordinary ABS plastic substrates to meet the increasingly high requirements.
