Electroplating process for high-abrasion-resistant environment-friendly plastic on washing machine door ring surface

Abstract

The invention provides an electroplating process for a high-abrasion-resistant environment-friendly plastic on a washing machine door ring surface. The electroplating process comprises the following steps: 1) oil removal; 2) expansion; 3) roughening; 4) reduction; 5) presoaking ; 6) activation; 7) dispergation ; 8) copper replacement; 9) copper plating under an acidic condition; 10) copper-tin alloy plating; 11) chrome plating ; 12) drying. The brand-new plastic electroplating process is provided through complete improvement of a conventional plastic electroplating process, the whole process is environment-friendly, non-toxic, and free of use of chemical plating; the operation is easier, the process stability is improved, the wastewater treatment is simple, the production time is greatly shortened, a hanger needs no replacement in the production process, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to an environmentally friendly plastic electroplating process on the surface of a door ring of a high wear-resistant washing machine. 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 electroplat...

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
