Problems solved by technology

In related technologies, products are prepared by homogeneous composite materials formed by resin and ceramic powder. However, compared with real ceramic products, the products are quite different in terms of hardness, luster and warm feel, and it is difficult to obtain real ceramic texture.
[0003] Therefore, the current ceramic shell and its preparation method still need to be improved

Abstract

The invention provides a shell. The shell comprises a polymer ceramic composite layer; the polymer ceramic composite layer comprises at least one of rod-shaped ceramic powder and a fiber material, and further comprises sheet-shaped ceramic powder and a polymer. According to the shell, the rod-shaped ceramic powder and / or the fiber material and the sheet-shaped ceramic powder are in lap joint to form a net-shaped heat conduction channel, so that the heat conduction performance and the partial strength of the shell are improved; and meanwhile, the specific surface area of the sheet-shaped ceramic powder is large, a light reflection effect is good, the surface glossiness and the ceramic texture of the shell are improved, and application of the shell is better facilitated. The invention further provides a preparation method of the shell and electronic equipment.

Description

technical field [0001] The present application belongs to the technical field of electronic products, and specifically relates to a casing, a preparation method thereof, and an electronic device. Background technique [0002] With the improvement of the consumption level, consumers have higher and higher requirements on the appearance, texture and performance of the housing of electronic products. At present, composite materials are prepared by blending some inorganic powders and resins to achieve certain characteristics, such as adding irregular calcium carbonate, barium sulfate and plastics to achieve cost reduction and enhancement effects; adding carbon nanotubes, glass fibers and plastics Composite to achieve toughening; adding graphite, graphene, metal particles and plastic composite to achieve electrical conductivity, thermal conductivity, etc.; the main material of these composite materials is still resin, and the prepared products are mainly plastic texture. In rece...
