Abstract

The invention relates to a preparation method of a ceramic cover plate, belongs to the technical field of ceramic processing, and solves the problems of low product yield and low production efficiencyin the prior art. The preparation method of the ceramic cover plate comprises the following steps: putting a zirconium oxide powder, an organic solvent and a dispersant into a ball mill proportionally, mixing for 1-12h, then adding an adhesive and a plasticizer, and continuing mixing for 1-25h to obtain a slurry; defoaming the slurry, and stopping defoaming when the viscosity of the slurry is increased to 7500-15000cPs; adjusting the scraper height of a casting machine, and casting to obtain a cast sheet; cutting the cast sheet, and punching out a pattern on a single layer of ceramic cast sheet by using a punch or a punch press with a patterned mould; laminating cast sheets, then wrapping after lamination, performing plastic packaging, and laminating a plastic packaged sample; placing a laminated sample in a sintering furnace, performing segmental degreasing and sintering to obtain a patterned ceramic blank. The preparation method is applicable to preparation of the ceramic cover plate.

Description

technical field

[0001] The invention relates to the technical field of ceramic processing, in particular to a method for preparing a ceramic cover plate. Background technique

[0002] With the comprehensive popularization of consumer electronic products, the degree of homogeneity of products is getting higher and higher, and the differentiation of the material and structure of the appearance parts of electronic products has become a new source of power to attract consumers. Compared with metal, glass and plastic, ceramics have the advantages of wear resistance, not easy to break, and good texture, and have become the new favorite of 3C consumer electronics. However, the current ceramic color system is single, so how to realize the differentiation of pattern design and color decoration is the key to cater to consumers.

[0003] In order to solve this problem, ceramic cover plate design manufacturers adopt processes such as spraying colored ink, paint or laser coating to real...
