Abstract

The invention provides an imitation electroplating spraying process used for automobile interior trim part machining, and belongs to the technical field of imitation electroplating spraying. The imitation electroplating spraying process includes the following steps that firstly, surface polishing and grinding are conducted; secondly, grease is removed, and complete cleaning is conducted; thirdly,surface activation is conducted through a flame gun; fourthly, a layer of black undercoat is sprayed, and surface drying is conducted; fifthly, a layer of imitation electroplating aluminum paste is sprayed, a layer of imitation electroplating aluminum paste continues to be sprayed after baking is conducted at the temperature being 65 DEG C for 5-7 min, and baking is conducted at the temperature being 65 DEG C for 5-7 min till the surface is half-dried; sixthly, a layer of silver powder is sprayed, baking is conducted at the temperature being 65 DEG C for 10-15 min, and then natural drying is conducted; and seventhly, varnish spraying is conducted for protection, and baking is conducted at the temperature being 50-65 DEG C for 10-15 min till the surface is dried. The imitation electroplating spraying process used for automobile interior trim part machining is easy and convenient to operate; and by adopting the imitation electroplating spraying process for the surfaces of automobile interior trim parts, obtained products can have good metal luster, are bright in color and have the effect of silver.

Description

technical field [0001] The invention belongs to the technical field of imitation electroplating spraying, and in particular relates to an imitation electroplating spraying process for processing automotive interior parts. Background technique [0002] Coating metal and non-metal surfaces can not only beautify the appearance, but also make metal and non-metal have certain functions, and it is used in many industries. The imitation electroplating process can make the effect produced on the surface of the product consistent with the effect produced by electroplating. Because of its convenient and quick operation, and the serious pollution in the electroplating industry, the imitation electroplating spraying process is more and more widely used, especially in automotive interior parts on the application. [0003] Most of the automotive interior parts are made of ABS plastic materials. In order to keep the appearance of the car body consistent, it needs to be coated on the surfa...
