Copper electroplating method for phenolic plastic

Abstract

The invention relates to a method for electroplating copper on phenolic plastics, which belongs to the field of electroplating technology. It is characterized in that it includes: soaking and cleaning the workpiece with 1% washing powder solution; drying the workpiece by drying or baking at medium temperature; dedusting the surface of the workpiece by strong wind; determining the type of conductive metal paint; using brass powder, silver-plated copper powder, sub-nanometer copper powder, aluminum paste and zinc powder to obtain conductive metal paint; determine the distribution ratio of each component of conductive metal paint: prepare conductive metal paint with polyester resin, solvent, sub-nanometer copper powder and additives, determine The mass fraction of polyester resin, solvent, sub-nanometer copper powder, and functional additives; the copper plating layer is prepared by acid copper plating method, and electroless copper plating. The surface of the phenolic plastic can be directly electroplated, which can change the current situation that the phenolic plastic cannot be directly electroplated, cannot be electroplated on a large scale, and is seriously polluted by electroplating sewage. The method of 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 str...

[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, the products after electroplating have strong metal texture and elegant appearance. 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 strong acids, strong complexing agents, and heavy metals.
