Abstract

The invention relates to a polymer surface treatment method. According to the method, an arc ion plating is adopted to enable a chromium film to be deposited on the surface of a polymer base body, the obtained chromium film has the silver appearance, and is similar to a sexavalence chromium film obtained through the electroplating process in appearance, meanwhile, in combination with the ion beam bombarding polymer surface and magneto-sputtering deposition nitride hard film technology, the film base combination force and film wear-resisting anti-corrosion performance can be greatly improved, the strong film base combination force is obtained from the polymer surface, the plating chromium imitation film which has the excellent properties of wear resistance, scratch resistance, corrosion resistance and the like can be obtained from the polymer surface, the decoration and protection function of the polymer base material can be achieved, and a full-dry type green surface treatment method without waste water discharge is obtained.

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,...
