Abstract

The invention relates to the technical field of plating films on the surface of organic polymers. The invention is realized through the following technical scheme that: the method for plating chromium on the surface of plastic materials sequentially comprises (1) a step for pretreatment; (2) a step for preparing a bottom plating layer; (3) a step for preparing a metallic chromium plating layer; (4) a step for preparing a surface plating layer; (5) inspection; and (6) packaging. The invention is suitable for the mechanical industry, transparent materials and other aspects.

Description

technical field [0001] The invention relates to the technical field of organic polymer surface coating, in particular to a method for chrome plating on plastic surfaces. Background technique [0002] Plastic has the characteristics of low price, light weight, corrosion resistance, electrical insulation, high-frequency shielding, easy processing, and short molding cycle, and has been widely used in various industries. Plastic can also use physical and chemical methods to coat or coat its surface to form a surface layer or covering layer with specific functions, which can significantly improve the decoration, physical and chemical properties of the surface of plastic products, especially to improve the hardness and durability of plastics. Scratch, abrasion resistance, fatigue strength and chemical stability, thus further expanding the range of applications. [0003] There are many methods of coating (coating) on ​​the surface of plastics, mainly including coating, thermal spr...
