Method for electroplating copper for phenolic plastic

Abstract

The invention discloses a method for electroplating copper for phenolic plastic, and belongs to the field of electroplating processes. The method is characterized by comprising the following steps: soaking and cleaning work-pieces by using a 1% washing powder solution; drying the work-pieces by using a spin-drying or medium temperature baking method; performing dust removal on the surfaces of the work-pieces by using strong wind; determining the types of conductive metallic paint; preparing the conductive metallic paint by using brass powder, silver-plated copper powder, sub-nano grade copper powder, aluminum slurry and zinc powder; determining the proportion of each component of the conductive metallic paint, namely preparing the conductive metallic paint by using polyester resin, solvents, the sub-nano grade copper powder and an auxiliary agent, and determining the mass percents of the polyester resin, the solvents, the sub-nano grade copper powder and the functional auxiliary agent; and preparing a copper-plating layer by using an acidic copper plating method, and performing chemical copper plating. By adopting the method disclosed by the invention, the surface of the phenolic plastic can be directly electroplated, and the current situations that the phenolic plastic cannot be electroplated directly or in large scale and serious pollution can be caused by electroplating sewage at present can be changed; and the method disclosed by the invention is simple to operate and easy to popularize.

Description

technical field [0001] The invention belongs to the field of electroplating technology, in particular to a method for electroplating copper on phenolic plastics. Background technique [0002] Due to the rich source of raw materials, simple synthesis process, low price, high mechanical strength, high temperature resistance, stable size, corrosion resistance, and excellent electrical insulation performance, phenolic plastics have strong metal texture and elegant appearance after electroplating. They can be used in the automotive industry, electronics Industry and other fields to replace acrylonitrile. Butadiene. Styrene plastics and some metal alloys, this electroplating process cannot be used for large-scale production, and the pollution is serious Not easy to control and other shortcomings, resulting in low yield after plating. In addition, the traditional electroplating process is complicated, consumes a lot of energy, and produces a large amount of sewage containing s...
