Embodiment 1-15

[0044] The shell base is made of a composite sheet made of co-extruded PC and PMMA plastic particles, or a plastic shell injection-molded with co-polymerized PC to form a hardened layer on one side of the shell base. Then sandblasting is performed on the surface of the hardened layer away from the base of the shell, wherein the shape of the alumina sand used in the sandblasting includes at least one of polygonal column shape and polygonal pyramid shape. The specific parameters of the blasting treatment are shown in Table 1 below.

Abstract

The invention provides a method for preparing a shell assembly, the shell assembly and electronic equipment. The method for preparing the shell assembly comprises the steps that the shell base body is provided, wherein the shell base body is made of plastic; forming a hardened layer on one side of the shell base body; and at least one part of the surface of the side, away from the shell base body, of the hardened layer is subjected to sand blasting treatment. Therefore, the surface of the shell assembly not only has a matt color effect, but also has a matt hand feeling, and the obtained shell assembly has the advantages of higher hardness and good wear resistance. In addition, the method has the advantages of being easy to operate and low in cost.

Description

technical field [0001] The application belongs to the technical field of surface treatment, and in particular relates to a method for preparing a housing assembly, the housing assembly and electronic equipment. Background technique [0002] At present, there are two ways to achieve a matte effect on the housing assembly of an electronic device. The first method is to use a texture mold on the inside of the housing assembly of an electronic device, for example, to achieve a matte effect by UV transfer printing. The second method is to carry out laser engraving treatment on the surface of the housing components of the electronic equipment, and achieve a matte effect through laser engraving. Since the first method is to process the inner side of the shell assembly, the contrast between light and dark gloss is not strong, and the handle is dull and matte. However, the products obtained by using the second method have the problems that the laser engraved area is not wear-resista...
