Problems solved by technology

This type of composite material mainly uses the content, type, shape, and particle size of ceramic powder to achieve the desired characteristics, but its solid content is limited, the interface is weak, and the compactness is poor. Compared with real ceramics, whether it is There is a large gap in hardness, gloss, and texture, and it is difficult to meet consumers' high pursuit of product appearance and texture.
At present, the ceramic shell and its preparation method still need to be improved

preparation example Construction

[0023] see figure 1 , is a flow chart of the preparation method of the housing provided in an embodiment of the present application, including:

[0024] S101: Modify the polymer to obtain a modified polymer, wherein the modified polymer includes a polymer and an aromatic group connected to the chain structure of the polymer, and / or the modified polymer includes a polymer and an aromatic group connected to A reactive group at the end of a polymer chain structure.

[0025] S102: blending the ceramic powder and the modified polymer, performing banbury granulation and injection molding to obtain a polymer ceramic sheet, and pressing the polymer ceramic sheet to obtain a polymer ceramic layer to obtain a casing.

[0026] In the present application, the modified polymer is used to improve the mechanical properties of the shell 100 and prolong the service life of the shell 100, which is beneficial to the application of the shell 100; the preparation method of the shell 100 is simple...

Embodiment 1

[0084] In the preparation process of the shell, zirconia and modified polyphenylene sulfide (PPS) are blended, and the shell is obtained after banburying, granulation, injection molding and pressing. Among them, the mass proportion of zirconia in the shell is 75%, and the mass proportion of modified PPS is 25%. The modified PPS is a PPS with naphthalene groups grafted on the side chain. The structural formula is as follows:

[0085]

Embodiment 2

[0087] Roughly the same as Example 1, the difference is that the modified PPS is a PPS grafted with amino end groups at the end of the main chain, and the structural formula is as follows:

Abstract

The invention provides a shell preparation method. The shell preparation method comprises the following steps that a polymer is modified to obtain a modified polymer, the modified polymer comprises the polymer and an aromatic group connected to a chain structure of the polymer, and / or the modified polymer comprises the polymer and a reactive group connected to the tail end of a chain structure of the polymer; ceramic powder and the modified polymer are blended, a polymer ceramic sheet is obtained through banburying granulation and injection molding, the polymer ceramic sheet is pressed to obtain a polymer ceramic layer, and a shell is obtained. The preparation method is simple and easy to operate, the shell with excellent performance can be prepared, and the application of the shell is facilitated. The invention further provides another shell preparation method, the shell and electronic equipment.

Description

technical field [0001] The application belongs to the technical field of electronic products, and in particular relates to a casing, a preparation method thereof, and electronic equipment. Background technique [0002] With the improvement of consumption level, consumers not only pursue the diversification of functions of electronic products, but also have higher and higher requirements for their appearance and texture. In recent years, ceramic materials have become a hot spot in the research of electronic equipment casings due to their warm and moist texture. However, at present, it is mainly through the blending of resin and ceramic powder that the gloss of the composite material is higher than that of plastic and lower than that of ceramics. This type of composite material mainly uses the content, type, shape, and particle size of ceramic powder to achieve the desired characteristics, but its solid content is limited, the interface is weak, and the compactness is poor. C...
