Colorful processing technology of colorful pattern mobile phone rear cover

Abstract

The invention discloses a colorful processing technology of a colorful pattern mobile phone rear cover. The colorful processing technology of the colorful pattern mobile phone rear cover comprises thefollowing steps of S1, processing a base material; S2, polishing and cleaning; S3, carrying out colorful three-dimensional texture pattern silk-screen processing; S4, carrying out coating processing;and S5, drying, exposing and developing. According to the colorful processing technology of the colorful pattern mobile phone rear cover provided by the invention, through colorful three-dimensionaltexture pattern silk-screen processing and coating processing, the double-colorful visual perception of the pattern and the mobile phone rear cover is realized, and the mobile phone rear cover with the colorful pattern and the colorful appearance can be obtained; through spraying multiple layers of powder coatings with different colors by covering a silk-screen net for many times, a three-dimensional pattern with the characteristics of strong color layering and long texture retention can be obtained, so that the visual perception of the pattern of the mobile phone rear cover is improved; and through damaging a correction plate and reducing the thickness of a physical film of an evaporation material, colorful colors are realized, and a colorful coating film is obtained on the vacuum evaporation surface of the mobile phone rear cover, so that the mobile phone rear cover has a colorful effect, and the attractiveness is ensured.

Description

technical field [0001] The invention relates to the technical field of mobile phone back covers, in particular to a colorful processing technology for mobile phone back covers with colorful patterns.

Problems solved by technology

The existing mobile phone back cover needs to be equipped with dazzling colors, and the existing coating process can only be coated with a single color, which is not suitable for the colorful coating requirements; and the existing mobile phone back cover also needs to be patterned, and the existing pattern making methods mostly pass The transfer printing technology is used to make the mobile phone back cover through the secondary heat transfer printing technology after spraying, so that the mobile phone back cover can obtain a plane texture pattern on its outer surface, but it cannot easily obtain a colorful image. The desired pattern, and this method makes the back cover of the mobile phone get the ink flat printing pattern, which lacks permeability in the coating and is easy to fade, and the retention is not long

Moreover, the pattern is a flat pattern, and the color layering of the drawing surface is less, which limits the visual perception of the pattern on the back cover of the mobile phone
