Production process of smooth and matte mobile phone backboard

Abstract

The invention discloses a production process of a smooth and matte mobile phone backboard. The smooth and matte mobile phone backboard comprises a transparent hardened layer, an outer texture effect layer, a composite base material, a silk-screen logo layer, a UV transfer printing layer, an electroplated layer and a cover bottom layer. An ultraviolet light filtering layer and a light scattering molecular layer are sequentially arranged between the transparent hardened layer and the outer texture effect layer from outside to inside, and the UV transfer printing layer is provided with a plurality of magnetic color-changing particles. The external light filtering layer is used for filtering ultraviolet light and reducing reflection of the ultraviolet light, so that damage of the ultraviolet light to eyes and influence of the ultraviolet light on internal pattern color ink are reduced, color weakening is prevented, and the pattern color display effect and the service life are guaranteed; by arranging the magnetic color-changing particles, pattern areas with different patterns can be drawn according to requirements, texture patterns of the pattern areas can be changed according to the requirements of a user, the variability and plasticity of the patterns are improved, by arranging the temperature-sensitive color-changing coating layer, the patterns of the pattern areas can change along with the change of the external temperature, and the requirements of the user are met.

Description

technical field [0001] The invention relates to the technical field of matte mobile phone backplanes, in particular to a production process for matte mobile phone backplanes. Background technique [0002] Mobile phones, referred to as mobile phones or wireless phones, are usually called mobile phones. They were originally just a communication tool. In the early days, they were commonly known as mobile phones. Like a computer, it has an independent operating system. Most of them are large-screen machines, and they are touch capacitive screens, and some are resistive screens. They are powerful and practical. It's a cell phone, almost everyone has one. As an important component of mobile phone components, mobile phone backplane is also the mainstream development in the current economic and manufacturing industry. [0003] As people's requirements for the quality of life are getting higher and higher, the quality requirements and performance requirements for mobile phones are ...

Problems solved by technology

[0003] As people's requirements for the quality of life are getting higher and higher, the quality requirements and performance requirements for mobile phones are also getting higher and higher. The current mobile phone backplane has a single structure and simple functions, which cannot meet people's needs. The aesthetics of the board is usually treated with a pattern layer on the surface of the backplane. However, this kind of pattern layer treatment can only make the backplane present a single color, which is poor in aesthetics and prone to glare interference. Irradiation will cause the color pigment of the pattern to decline, resulting in a decrease in the display effect of the pattern and affecting the aesthetics; and the patterns on the back of the existing mobile phone are mostly fixed specifications, and different patterns cannot be freely transformed according to the needs of users. If you want to change the pattern, you can only change it through the film or the mobile phone case, but the display effect of the pattern in this way is poor, and the pattern cannot show different colors according to different temperatures, and the color changing effect cannot be achieved, which cannot satisfy existing users. board needs
