Abstract

The invention discloses an electronic equipment casing, which comprises a base body, a texture layer and a coating layer sequentially stacked on the base body, and inorganic particles are dispersed in the texture layer. The present invention disperses inorganic particles in the texture layer of the electronic equipment casing, and the inorganic particles can effectively reduce the thermal expansion coefficient of the texture layer, so that the difference between the thermal expansion coefficient of the texture layer of the electronic equipment casing and the thermal expansion coefficient of the coating layer is reduced, and the thermoforming During the process, the thermal stress between the texture layer and the coating layer is reduced, and the problem of cracking of the coating layer is significantly improved.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to an electronic equipment shell and the electronic equipment. Background technique [0002] With the advent of the 5G era, due to the limited signal penetration ability of metal shells, its application in the 5G field is limited to a certain extent. Therefore, the choice of polymer materials that are conducive to 5G signal penetration as electronic equipment shells The widespread attention of engineers is expected to be used in large-scale commercial applications. By setting a multi-layer structure such as texture layer, coating layer and ink layer on the substrate, the electronic device housing based on polymer material can have the visual effect of optical texture pattern and metallic luster, thereby enhancing the polymer material housing. texture. On the other hand, in order to make the electronic equipment have a good feel, it is also necessary to hot-press the housing of t...
