Product surface double-color glaze and matte treatment method

Abstract

The invention discloses a product surface double-color glaze and matte treatment method. Firstly, a layer of silver powder paint is sprayed to a product surface, and a layer of colored paint is sprayed to the surface of the silver powder paint; a layer of transparent colorless UV / PU paint is sprayed to the surface of the colored paint; a film layer with indium as a target material is plated on the surface of the UV / PU paint; a layer of transparent colorless UV / PU protective paint is sprayed on the surface of the film layer; part of the UV / PU protective paint and the film layer of a product are carved out through an optical fiber laser etching machine; the area formed after laser etching is deplated, and gasified matter formed after laser etching is removed; a layer of transparent colorless UV / PU intermediate paint and a layer of transparent colorless UV / PU surface paint are sprayed; the area subjected to laser etching and pervious to the colored paint is subjected to extinction treatment through a carbon dioxide laser etching machine. In the product surface double-color glaze and matte treatment method, the product can present a metallic look high in light reflection due to the film plating procedure. By means of laser etching, the film layer and the protective paint at some positions are carved out, the positions are pervious to the color of bottom paint, finally, the surface of the whole product is sprayed with the intermediate paint and the surface paint, the corresponding area pervious to the bottom paint after laser etching is subjected to extinction treatment, and the double-color glaze and matte integral effect is achieved on the product surface.

Description

technical field [0001] The invention relates to a painting process, more precisely, relates to a treatment method for two-color matte product surface. Background technique [0002] With the development of science and technology, people have higher and higher requirements for electronic products, especially mobile phones. These requirements not only include the performance of mobile phones, but consumers pay more attention to the appearance of mobile phones. Existing mobile phone shells are painted by common processes, either the overall color of the mobile phone shells is consistent, or the spray paint is not reliable, which does not meet the requirements of the mobile phone paint spraying process. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a two-color matte treatment method on the surface of a product. [0004] The technical solution of the present invention is: a kind of processing method of product...
