Vacuum decoration coating technique of high polymer material product

Abstract

The invention discloses a vacuum decoration coating technique of a high polymer material product, which comprises the following steps: product surface cleaning, product surface plasma activation, Cr layer plating by high-power magnetron sputtering, fine arc ion plating of functional layer, and high-power magnetron sputtering of protective layer. The film prepared by the technique mainly comprises a Cr base layer, an ion plating functional layer and an oxide protective layer. The technique is used for substituting electroplating treatment, avoids the pollution of three wastes, enhances the added value of the high polymer product, and can provide more colors and appearances.

Description

technical field [0001] The invention relates to a material surface treatment process, in particular to a vacuum decorative coating process for polymer electromechanical products. Background technique [0002] At present, a large number of electromechanical products and their supporting materials are made of polymer materials. Polymer materials are materials composed of compounds with relatively high molecular weights, including rubber, plastics, fibers, coatings, adhesives and polymer-based composites. materials etc. Vacuum ion plating cannot be directly coated on the surface of polymer materials.

Vacuum ion plating cannot be directly coated on the surface of polymer materials. The surface coating of traditional polymer products generally adopts the method of electroplating. Electroplating has high requirements on the conductivity of materials, and general polymer materials are insulating. Therefore, it is necessary to do a lot of modification to the polymer material and implant conductive particles, otherwise the film-forming performance is poor, and the gloss and appearance are not good

The more advanced process is to make a primer first, then evaporate aluminum, and then cover the top coat. The process is complicated and the effect is poor. It is difficult to achieve the fullness and gloss of the electroplating. At the same time, the color is easy to yellow and the metal texture is poor.

[0003] The important thing is that the "three wastes" of traditional electroplating surface treatment are seriously polluted, especially electroplating wastewater is a high-concentration refractory toxic and harmful wastewater containing hydrochloric acid, sulfuric acid, heavy metals and other substances, resulting in a large amount of heavy metal precipitation and extremely serious pollution

In order to treat electroplating wastewater, it needs to invest more money, forming a vicious circle
