Abstract

The invention provides a cement-based compound material used for a mobile phone shell and a ceramic-based compound material mobile phone shell and a preparation method thereof. The cement-based compound material used for the mobile phone shell is prepared from, by weight, 80-85 parts of ZrO2 nano powder, 8-15 parts of thermoplastic resin, 3-8 parts of a dispersing agent and 3-5 parts of a plasticizer. The cement-based compound material used for the mobile phone shell integrates noble texture of ceramics and toughness and plasticity of macromolecules, and can be machined. Leftover materials can be conveniently recycled, and the cement-based compound material is low in cost and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a mobile phone case, in particular to a ceramic matrix composite material used for a mobile phone case, a ceramic matrix composite mobile phone case and a preparation method thereof. Background technique [0002] The mobile phone shell is not only the most direct way to protect the body, but also an important factor affecting its cooling effect, weight, and aesthetics. Therefore, the materials for making mobile phone casings are required to have the characteristics of high strength, good heat resistance and wear resistance, electromagnetic shielding, stable dimensions, and good appearance. At present, most of the mobile phone casings on the market are made of engineering plastics, metals, glass and other materials. These materials have disadvantages such as low hardness, easy scratches, deformation, fading, environmental protection, and heat resistance. Due to its beautiful appearance, jade-like luster and smooth feel, the app...
