Abstract

The invention belongs to the field of architectural ceramics processing, in particular to a white toner for architectural ceramics and a preparation method thereof. The architectural ceramic white toner comprises: 50-80 parts by weight of resin; 25-40 parts by weight of white ceramic pigment; 2-8 parts by weight of wax; 3-8 parts by weight of charge regulator; 0.2-1 part by weight of fumed silica . The prepared white ceramic toner for building ceramics has high whiteness, high temperature resistance and excellent thermal stability. After high temperature sintering, the text or pattern on the surface of the ceramic substrate still does not fade, and the image quality is high; in terms of preparation technology , the traditional two-step process of crushing and modification is changed to an integrated process of crushing and modification, and surface modification is completed at the same time as ultra-fine crushing, which simplifies the process, improves efficiency, effectively controls particle size distribution, and reduces costs. ; In line with the concept of energy saving and environmental protection, it has great market prospects and economic value.

Description

technical field [0001] The invention belongs to the field of architectural ceramic processing, and in particular relates to a white toner for architectural ceramics and a preparation method thereof. Background technique [0002] Ceramic digital inkjet has developed rapidly in the architectural ceramics industry, bringing rapid changes to architectural ceramics. Ceramic digital inkjet not only enriches products but also makes personalized customization possible. In order to improve the utilization rate of the color material and avoid the disadvantage of low resolution caused by the diffusion of ceramic inkjet, a laser printer is used to print the texture pattern of architectural ceramics on the adhesive film, and then soak the decal paper printed with the texture pattern in clean water. Separate the adhesive film from the white paper, then peel off the adhesive film with the textured pattern and stick it on the glazed brick, and pour the glaze. Put the bricks with the textu...
