Problems solved by technology

Although the above techniques can obtain a metal-like imitation plating layer, due to the existence of a large number of irregular and discontinuous film holes on the surface of the paint film, water vapor and corrosive media can easily penetrate into the metal evaporation coating layer and corrode the metal layer, thus affecting the appearance and use.

Abstract

The invention relates to a metal or non-metal anhydrous low-cost imitation electroplating film and a surface treatment method thereof. The method comprises the following steps that a formed workpieceis subjected to hydrocarbon ultrasonic cleaning, oil removal and wax removal, then UV paint with a high hydroxyl value is sprayed on a workpiece, leveling, drying and curing are carried out, then theworkpiece is placed in a vacuum furnace for plasma glow treatment, then vacuum coating treatment is carried out, the UV paint with a high hydroxyl value is sprayed on the workpiece plated with the film, then the workpiece is enabled to enter the vacuum furnace again to sputter the silicon target, and the oxygen content is gradually increased. And finally, the workpiece plated with the gradient silicon and the silicon dioxide is immersed into a low-surface-energy solution, and the hydrophobic and corrosion-resistant imitation electroplating coating is obtained through drying at a low temperature. The imitation electroplating film can be widely applied to the fields of hardware, household appliances, bathroom accessories, automobile accessories and the like, and has the advantages of no wastewater discharge, low cost, excellent performance and the like.

Description

technical field [0001] The invention relates to an anhydrous low-cost imitation electroplating film and a surface treatment method thereof. Background technique [0002] Metal or plastic surface products need to enhance corrosion resistance, increase hardness, prevent wear, improve electrical conductivity, lubricity, heat resistance, and beautiful surface, and often require electroplating treatment. The electroplating process has been developed to the present, and it has become a very important processing technology at present, and it occupies a large proportion in protection and decoration. Especially in the electronic industry, communication and military industry, aerospace and other fields, a large number of functional electroplating technologies are used. Although the application of electroplating is very extensive, electroplating is also one of the three major polluting industries, and it will also bring great harm to people's health. [0003] With the improvement of ...
