Embodiment 1

[0060] A method for preparing a polymer ceramic shell, comprising:

[0061] The polymer ceramic sheet is subjected to warm isostatic pressing to obtain a pressed structure, wherein the polymer ceramic sheet includes ceramic and polyphenylene sulfide (PPS), and the mass content of the ceramic in the polymer ceramic sheet is 80%.

[0062] The two opposite surfaces (the first surface and the second surface) of the laminated structure are subjected to ultraviolet light, including irradiation at a wavelength of 365nm for 180s; then placed at 310°C for 9 hours to obtain a polymer ceramic shell, a polymer ceramic shell The degree of cross-linking of polyphenylene sulfide gradually increases from the middle to both sides along the thickness direction of the polymer ceramic shell.

Embodiment 2

[0064] A method for preparing a polymer ceramic shell, which is roughly the same as in Example 1, except that ultraviolet light is not used, but high-energy ion impact is performed on the two opposite surfaces of the laminated structure, wherein the incident energy is 300W, The treatment time is 30s, and then placed at 310°C for 9 hours to obtain a polymer ceramic shell. The degree of crosslinking of polyphenylene sulfide in the polymer ceramic shell gradually increases from the middle to both sides along the thickness direction of the polymer ceramic shell.

Abstract

The invention provides a polymer ceramic shell, and the shell comprises ceramic and a polymer, wherein the crosslinking degree of the polymer in the polymer ceramic shell is gradually increased from the middle to the two sides in the thickness direction of the polymer ceramic shell. The polymer in the polymer ceramic shell is small in crosslinking degree and good in toughness, the impact resistance of the polymer ceramic shell is improved, the outside of the polymer ceramic shell is large in crosslinking degree, high in surface density, low in surface energy, large in hardness and excellent in wear resistance, meanwhile, the polymer ceramic shell further has ceramic texture and appearance, and application of the polymer ceramic shell is better facilitated. The invention further provides electronic equipment with the polymer ceramic shell.

Description

technical field [0001] The application belongs to the technical field of electronic products, and in particular relates to polymer ceramic housings 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.
