Problems solved by technology

[0009] Therefore, through the method for chrome plating on the surface of non-metallic material products of the present invention, since the whole process does not need to spray conductive paint and use high chromic acid, it can effectively reduce environmental pollution, and can greatly shorten the time for subsequent electroless plating or electroplating. At the same time, It can effectively overcome the problem of uneven chromium film in irregular areas of vacuum coating, effectively reduce the surface resistance and form a thicker film

Embodiment Construction

[0011] The invention provides a method for chrome plating on the surface of non-metallic material products, which is used to generate the required chromium film layer on the surface of non-metallic material workpieces, wherein the non-metallic workpieces can be plastic products, plexiglass products, fiberglass products, ceramics Products, wood products, clay products, etc.

[0012] The method mainly includes the following steps:

[0013] First, surface pretreatment is carried out on non-metallic material workpieces. Wherein, the above-mentioned surface pretreatment can be any combination of degreasing, cleaning, drying, roughening and other steps, which may not be exactly the same according to different workpiece materials.

[0014] Secondly, after surface pretreatment, the above-mentioned workpiece is vacuum-coated to coat a layer of chromium on its surface and make its surface resistance meet a certain requirement. The above-mentioned vacuum coating can be vacuum sputterin...

Abstract

The invention provides a non-metallic material product surface chrome-plating method. After surface pretreatment of a non-metallic material workpiece, the above workpiece undergoes vacuum coating so as to plate a chrome layer on the surface of the workpiece. Then, area resistance meets a certain requirement. The workpiece then undergoes chemical plating or electroplating such that the surface of the non-metallic product is plated with the required chrome layer. By the method, environmental pollution can be effectively reduced, production efficiency can be improved, and area resistance of the product surface can be effectively lowered.

Description

technical field [0001] The invention relates to a method for chrome-plating the surface of non-metal material products. Background technique [0002] In modern industrial production, in order to expand the application range of non-metallic materials, or to achieve a certain special effect, for example, to make the surface of non-metallic material products conductive, or to improve the hardness, wear resistance, anti-aging, and moisture-proof of the surface , anti-solvent corrosion, etc., or to make the surface look like a metal to achieve the purpose of aesthetics, usually the secondary processing method is used to coat the required metal material layer on the surface of the non-metallic material. [0003] Overall, most of the methods of surface metallization of non-metallic material products are the following two methods: [0004] One is to pretreat the surface of non-metallic products first, try to make a conductive film (layer) on the surface, and then use traditional el...
