Process for electroplating plastic on automobile mask

Abstract

The invention provides a process for electroplating plastic on an automobile mask. The process comprises the following steps: 1), oil removal; 2), expansion; 3), roughening; 4), reduction; 5), preimpregnation; 6), activation; 7), dispergation ; 8), copper replacement; 9), acid copper plating; 10), copper-tin alloy plating; 11), chrome plating ; 12), drying. The brand-new plastic electroplating process is provided through complete improvement on a whole conventional plastic electroplating process, the whole process is environment-friendly, non-toxic and harmless, chemical plating is not required to be used, the operation is easier, the process stability is improved, the wastewater treatment is simple, the production time is greatly shortened, a hanging tool is not required to be replaced in the production process, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a plastic electroplating process for an automobile mask. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of the base material by the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal Oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and improve appearance. [0003] Among them, in addition to iron-based cast iron, steel and stainless steel, the electroplating substrate materials also include non-ferrous metals, or ABS plastics, polypropylene, polysulfone and phenolic plastics, and electroplating on the surface of plastic substrates is called plastic electroplating. . Plastic electroplating products have the advantages of light weight, easy processing, surface...

Problems solved by technology

However, the patent document only gives the relevant steps in the electroplating process, but does not give a corresponding solution for the pretreatment and electroless plating before electroplating. The plastic electroplating process of the electroplating factory includes a whole set of processes, only for electroplating. The improvement of the workshop cannot fundamentally solve the problems caused by the existing plastic electroplating process
