[0002] At present, in order to improve the visual effect and prevent the phone from slipping, some mobile phones have textures on their back covers, which improve the refraction effect of light and increase the contact area with the human hand. However, the height of the texture of the existing mobile phone back cover is usually around 12μm, so the visual effect and anti-slip effect of the mobile phone back cover are not obvious enough. One reason for the limitation of texture height is that the existing texture processing method is to directly form the back cover of the mobile phone and then perform CNC processing, so that the height of CNC processing should not be too high to avoid excessive force applied by the CNC equipment to the back cover of the mobile phone.

[0003] Therefore, how to increase the height of the texture to form a high-crown texture is an urgent problem that needs to be solved in the industry. Summary of the invention

[0004] The utility model aims at solving the problems of the prior art and provides a mobile phone back cover with a high crown texture. The high crown texture is produced by processing a PET layer into a high crown texture and then transferring the texture to a glue layer, thereby preventing excessive force applied by a CNC device from affecting the fitting effect of the entire mobile phone back cover.

[0007] The coating layer is prepared by a coating process.

[0008] Furthermore, the bottom cover includes four layers of substrates stacked in sequence, and the thickness of one layer of substrate is 0.8-1 μm; one end of the bottom cover is bonded to the LOGO layer, and the other end of the bottom cover is provided with a protective layer, and the protective layer, the bottom cover, the LOGO layer, the PC layer, the glue layer and the texture layer are bonded in this way by high-pressure pressing.

[0009] Furthermore, the thickness of the PC layer is 0.5 mm.

[0010] Furthermore, the LOGO layer includes a base material and an ink layer. The ink layer is printed on one end of the base material close to the PC layer. The base material is located between the cover bottom and the PC layer.

[0011] Furthermore, the base material is provided with a groove adapted to the shape of the LOGO, and the ink layer is printed in the groove.

[0012] Furthermore, texture structures are respectively provided at both ends of the PET layer, and the coating layer is coated on the texture structures.
