Problems solved by technology

[0005] In addition, the shortcomings of the traditional wet electroplating process are: high water consumption and energy consumption; discharge of a large amount of waste water containing heavy metal ions, cyanide, acid and alkali and organic pollutants to the environment, as well as various types of acid mist and dust. Toxic exhaust gas; it is easy to cause fire and cause heavy losses, and because there are a lot of chemical substances on site, the fire is difficult to control and it is easy to explode, which is extremely harmful

Abstract

The invention relates to a polymer surface treatment method. The method uses arc ion plating to deposit a chromium film on the surface of the polymer substrate, and the obtained chromium film has a silver-white appearance, which is similar to the appearance of the hexavalent chromium film prepared by electroplating. And the use of magnetron sputtering to deposit a nitride hard film layer technology greatly improves the film-base bonding force and the wear-resistant and anti-corrosion performance of the film layer, and obtains strong film-base bonding force on the polymer surface, and is wear-resistant and scratch-resistant The imitation electrochrome plating film layer with excellent properties such as corrosion resistance and corrosion resistance can realize the decoration and protection function of the polymer substrate, and it is a completely dry green surface treatment method without waste water discharge.

Description

technical field [0001] The invention relates to a material surface treatment technology, in particular to a green preparation method of an imitation electrochrome plating layer on a polymer surface. Background technique [0002] Polymer materials have the characteristics of low cost and light weight, and are widely used in optics, automobiles, packaging, microelectronics, medical treatment and other fields. However, polymer materials are relatively soft. In order to improve their weather resistance, scratch resistance, corrosion resistance and aesthetic effects, their surfaces are often treated to prepare metal or ceramic films. [0003] In the surface treatment technology of polymer materials, electroplating chrome film is a commonly used method, especially widely used in automobiles, sanitary ware and other fields. [0004] At present, when electroplating chromium film on the surface of polymer materials such as plastics, copper and nickel are usually electroplated first,...
