Problems solved by technology

Among them, the optical film layer mainly forms a specific absorption effect by controlling the thickness and number of layers of the film layer. At present, Huawei’s P20 glass back shell has been processed in this way to achieve an overall gradient effect. However, the application of this process in ceramics There is no relevant report yet; color glaze is to finish glaze color or in-glaze color or under-glaze color on the surface of ceramics to obtain gorgeous patterns or bright and beautiful colors. This process has been widely used

Example Embodiment

[0048] According to the method for preparing flow pattern multi-color ceramics according to the embodiment of the present invention, the flow pattern multi-color ceramics are prepared by using zirconia powder with consistent physical properties. During the molding process, the particle gradation consistency can be improved, and the powder inside the green body Good bulk accumulation and filling, the number of residual pores in the multi-color powder block is significantly reduced, and the distribution of residual pores is significantly improved. When at least two monochromatic zirconia powders are pressed, the color of each powder is selected And the pressing form determines the texture pattern of the final flow pattern multi-color ceramics; cold isostatic pressing of the multi-color powder block can significantly increase the density uniformity of the multi-color powder block, thereby improving the final flow The quality of multi-color ceramics; during the sintering process, zi...

[0057] Example 1

[0058] After the above tests, black and white yttrium stabilized zirconia powders are selected, and the shrinkage values ​​of the two at various temperatures are as follows image 3 As shown, the mass ratio of black and white yttrium stabilized zirconia powder is 9:1. When pressing and forming, use a mesh plate for cloth. The yttrium-stabilized zirconia powder was put into the mold in 3 times, the first time was 60wt% of the black yttrium-stabilized zirconia powder, then 100wt% of the white yttrium-stabilized zirconia powder was taken, and finally the remaining 40wt% of the black yttrium-stabilized zirconia powder The zirconium powder is fabricated and molded under the conditions of 18MPa and 20s holding pressure to obtain a multi-color powder block. A total of 10 multi-color powder blocks are prepared according to the same formula and method;

Abstract

The invention discloses flow line type multicolor ceramic as well as a preparation method and an application thereof. The method comprises steps as follows: (1) physical properties of at least two kinds of single-color zirconium oxide powder are characterized to obtain characterization data; (2) on the basis of the characterization data, the zirconium oxide powder with consistent physical properties is screened out; (3) the at least two kinds of single-color zirconium oxide powder which are screened out in the step (2) and have the consistent physical properties are mixed and subjected to pressing formation to obtain a multicolor powder block; (4) the multicolor powder block is subjected to isostatic cool pressing to obtain an uniform and dense multicolor powder block; (5) the uniform anddense multicolor powder block is sintered to obtain the flow line type multicolor ceramic. By means of the method, the multicolor ceramic is prepared, and the obtained flow line type multicolor ceramic has strong appearance expression force, has diversified colors and can well meet demands of all products.

Description

technical field [0001] The invention belongs to the field of ceramic preparation, in particular, the invention relates to flow pattern multi-color ceramics and its preparation method and application. Background technique [0002] Zirconia ceramics have the characteristics of high strength, high hardness, high wear resistance, scratch resistance and corrosion resistance, and its phase change toughening mechanism and thermal expansion coefficient are close to those of metals, so they are widely used in various fields. Such as cutting tools, molds, valves, refractory materials, oxygen sensors, solid fuel cells, etc. In addition to the above characteristics, zirconia ceramics have become a popular appearance shell material because of their noble texture and jade-like color. [0003] At present, the production process of monochromatic zirconia ceramic materials on the market is relatively mature, especially white and black. However, as an exterior part, not only does it have ex...
