Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] refer to figure 1 As shown, the present invention provides a method for coloring zirconia ceramics, which has the beneficial effects of bright color and stable color.

[0023] Concrete coloring method comprises the following steps:

[0024] S1: Provide transparent or translucent zirconia ceramics;

[0025] S2: spraying ink on the zirconia ceramics and heating and drying at 70-80°C to form an ink layer, specifically, spraying ink on the front or back of the zirconia ceramics provided in step S1, or spraying ink on both the front and back;

[0026] S3: forming a protective film with a thickness of 5-10 μm on the ink layer by magnetron sputtering, specifically, including the following steps:

[0027] S31: Form SiO on the ink layer by magnetron sputtering 2 (silicon dioxide) film;

[0028] S32: On SiO 2 Magnetron sputtering on the surface of th...

Abstract

The invention provides a zirconium oxide ceramic coloring method and a preparation method of a mobile communication equipment shell. The zirconium oxide ceramic coloring method comprises the following steps: providing transparent or semi-transparent zirconium oxide ceramics; spraying the zirconium oxide ceramics with ink, then heating and drying to form an ink layer; forming a protective film on the surface of the ink layer through magnetron sputtering.

Description

technical field [0001] The invention relates to the field of ceramic products, in particular to a method for coloring zirconia ceramics and 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, zirconia ceramics have become the most promising next-generation casing material. [0003] Zirconia ceramics have excellent mechanical properties, but the color is relatively monotonous. At present, most of them are blac...
