Abstract

The invention provides a zirconia ceramic mobile phone panel and a preparation method thereof and belongs to the field of mobile phone panel preparation. The zirconia ceramic mobile phone panel is mainly prepared from, by weight, 80-99.5 parts of a zirconia powder and stabilizer mixture and 0.5-20 parts of organic carriers, wherein molar ratio of stabilizers in the zirconia powder and stabilizer mixture is 4-6%. The preparation method includes mixing the zirconia powder with the stabilizers to obtain a primary mixture; adding the organic carriers into the primary mixture with mixing uniformly so as to obtain a mixture; enabling the mixture to form so as to obtain a panel blank; subjecting the panel blank to organic carrier removal prior to sintering so as to obtain the zirconia ceramic mobile phone panel. The zirconia ceramic mobile phone panel made from special materials is highly smooth in hand feeling, good in colorfulness and light transmission performance, resistant to wear and slip and less prone to breakage.

Description

Technical field [0001] The invention relates to the field of cell phone panel preparation, in particular to a zirconia ceramic cell phone panel and a preparation method thereof. Background technique [0002] At present, the traditional injection molding process is commonly used in the manufacture of mobile phone panels, including three separate manufacturing processes: injection molding of the outer casing of the mobile phone, the window lens (or display screen), and the joining of the outer casing and the lens. [0003] Among them, the raw materials used for the window lens are PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene copolymer), PMMA (polymethyl methacrylate) and in-mold transfer film. The process is complicated and the molding is The yield rate is low, and the cost of raw materials, molds, and machines are high. [0004] In addition, for window lenses, glass processing is often used in related technologies. This method of glass processing window lenses also has the p...
