Abstract

The invention discloses a preparation method of a mobile telephone shell. The preparation method comprises weighing yttrium oxide-stabilized zirconia powder and a surfactant according to a mass ratio of the surfactant to yttrium oxide-stabilized zirconia powder of 1-5: 100, adding ethanol into the weighed materials, carrying out ball milling mixing, carrying out drying and sieving to obtain slurry, mixing the slurry and a binder, carrying out mixing and granulation to obtain feed for injection, wherein the binder comprises polyethylene glycol, oxidizing high density polyethylene, polyvinyl butyral and stearic acid, carrying out injection molding on the feed to obtain a green body, carrying out staining detection on the green body, putting the green body into water, carrying out water debinding, carrying out thermal debinding to obtain a blank, sintering the blank to obtain a semifinished product, and carrying out machining and polishing on the semifinished product to obtain the mobile telephone shell. The mobile telephone shell has high strength, is not easily broken and has high density and uniform apertures. The preparation method has simple processes, operation easiness and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of zirconia ceramics, in particular to a method for preparing a mobile phone casing. Background technique [0002] As a new type of high-tech ceramics, zirconia ceramics have properties such as high strength, high fracture toughness, high hardness, excellent heat insulation performance and high temperature resistance, and are widely used in the fields of structural ceramics and functional ceramics. In addition, zirconia is non-magnetic, non-conductive, non-rusting, and wear-resistant. It is also widely used in the field of biomedical equipment, props, and tools. Recently, partially stabilized zirconia (TZP) can be used to prepare magnetically shielded watch cases, corrosion-resistant watch parts and other instrument parts by powder metallurgy. In addition to the above applications, TZP is also widely used in decoration, life, medicine, piezoelectric ceramics, sensor ceramics and other fields. [0003] The ...
