Production process of polished matte pearl powder-added mobile phone backboard

Abstract

The invention discloses a production process of a polished matte pearl powder-added mobile phone backboard. The production process comprises the following steps of (1) processing a composite base material; (2) carrying out silk-screen processing on a silk-screen logo layer; (3) printing and processing a transfer printing pattern layer; (4) printing and processing an electroplated layer; (5) printing and processing a cover bottom layer; (6) carrying out printing and processing on an astigmatism reinforcing layer; (7) processing a rubbing texture layer; (8) processing the transparent hardened layer; (9) carrying out high-pressure forming processing; and (10) cutting, processing and forming the mobile phone backboard. According to the production process, the three-dimensional display effect that the pattern color gradually changes from dark to highlight is achieved, the rubbing texture layer is combined to reflect rich gradient color textures, the texture display effect is improved, and the ornamental value is improved; and by providing the astigmatism molecular layer and the astigmatism structure to form a double astigmatism structure, the reflected light of the color pattern reflects color light of different angles, the distortion problem is avoided, and the rich color and texture effect is reflected.

Description

technical field [0001] The invention relates to the technical field of mobile phone backplane production, in particular to a process for producing a mobile phone backplane with matte and pearlescent powder. Background technique [0002] With the development of science and technology, mobile terminals such as mobile phones and tablet computers are increasingly used in people's work, study, daily communication and other aspects. Mobile phones are currently the most commonly used 3C products, occupying a mainstream position in the market. [0003] As a product that people use frequently, mobile phones have higher and higher requirements for mobile phone products. In addition to higher hardware requirements for mobile phone products, users are paying more and more attention to the appearance of mobile phone products. The appearance of mobile phone products can bring users a direct visual experience, which largely determines the user's evaluation of product quality. The surfac...

Problems solved by technology

The patterns of the existing mobile phone back panels are mostly flat patterns, single color, poor three-dimensional layering, and poor aesthetics, and the light after the color pattern processing of the existing mobile phone back panels is reflected through the reflective layer. The angle is mostly fixed, the coverage of reflected light is low, and due to multi-layer reflection, the light will be weakened after passing through the color pattern layer, so that the texture and logo pattern of the texture layer cannot be clearly displayed, and the color layer is reflected in the light. The lower color effect is also significantly reduced; in order to increase the differentiation, and to further improve the appearance quality of the product and meet the increasingly higher aesthetic requirements of users, the present invention provides a production process for the back panel of a mobile phone with matte and pearlescent powder
