Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] refer to figure 1 As shown, the present invention provides a method for preparing a communication device shell, which has a high product yield, thereby reducing production costs, and has beneficial effects such as product density, fracture toughness, and bending strength.

[0024] Specifically include the following steps:

[0025] Step S1, slurry mixing: mixing zirconia ceramic powder with a solvent and a binder to form a mixed slurry;

[0026] Wherein the zirconia ceramic powder is added with any one or more powders of yttrium oxide, titanium oxide and silicon oxide; the solvent is alcohol or toluene; the adhesive is any one of PVB1 or PVB2.

[0027] Step S2, forming: mixing the slurry to obtain a single-layer base film tape with a thickness of 0-1 mm by tape casting, and preparing superimposed film tapes of different thicknesses on the base f...

Abstract

The invention provides a preparation method for a mobile communication equipment outer shell. The mode that sintering and hot bending are integrated is adopted, the working procedure is reduced, thus the risk of deformation caused by independent sintering is avoided correspondingly, the yield rate of a product is greatly increased, and therefore the production cost is reduced; and meanwhile a certain pressure is applied in the sintering process, so that finally, the prepared product is good in density, fracture toughness, bending resistance and the like.

Description

technical field [0001] The invention relates to the field of ceramic products, in particular to a method for preparing a casing of a mobile communication device. Background technique [0002] With the continuous development of mobile phone networks, the existing 4G technology can no longer meet the needs of high-speed information transmission, and 5G technology puts forward stricter requirements for the design of the mobile phone antenna and the material of the casing. At present, the mature metal casing plus nano-injection molding process can no longer meet the 5G signal requirements. Although the glass has good signal penetration ability, the glass strength is low and it is easy to break when dropped. Therefore, ceramics have become the most promising next-generation casing materials. [0003] At present, for the preparation of ceramic mobile phone shells, two schemes are commonly used: CNC (CNC machine tool) direct processing and dry pressing preforming followed by CNC p...
