Plastic substrate electroplating method

Abstract

The invention discloses a plastic substrate electroplating method. According to the plastic substrate electroplating method, the treatment time of such processes as roughing, copper plating and nickel plating is reduced, a semi-bright nickel plating process in a traditional electroplating process is directly cancelled, the production capacity is greatly improved, the electroplating cost and the usage amount of chromium are reduced so that the pollution on the natural environment is reduced, and the time taken by the traditional process and the thickness of a copper plated layer as well as the thickness of a nickel plated layer are reduced; the plastic substrate electroplated surface finally treated by use of a PVD coating method is more environment-friendly in contrast with the traditional electroplating process, and is better in heat resistance, corrosion resistance, scratch resistance and oxidation resistance; and in addition, a temperature and a gas content adopted in the PVD coating technology are adjusted so that the PVD films of various bright colors with strong metal texture and third dimension can be formed to overcome the shortcoming of thin colors that can be plated by use of the traditional plastic electroplating process.

Description

technical field [0001] The invention relates to the technical field of surface treatment methods for plastic substrates, in particular to an electroplating method for plastic substrates. Background technique [0002] The traditional plastic electroplating process is relatively complicated and consumes a lot of energy and time. This traditional plastic substrate electroplating process takes as long as 3 to 4 hours to complete the electroplating on the surface of the plastic substrate. Moreover, the colors that can be reflected by the traditional plastic substrate electroplating process are also very limited, and the colors are relatively thin. Can't satisfy the aesthetic demand of modern people to article. The harmful substances included in the traditional plastic substrate electroplating process are highly toxic chemicals such as hexavalent chromium, trivalent chromium, sulfuric acid, etc., which are very serious to the human natural environment and human body. However...

Problems solved by technology

Moreover, the traditional electroplating process produces a large amount of sewage and consumes a large amount of electricity and water power. A fully automatic circulation electroplating production line can process about 20,000 square meters of electroplating surface in one month and remove about 2,000 tons of sewage.

So much sewage wastes a lot of water resources and seriously pollutes the human ecological environment, so it is urgent to improve or replace this traditional electroplating process
