Problems solved by technology

This layer of glaze can improve the surface properties of the green body, improve the performance of the ceramic tile product, and increase the aesthetic feeling of the product. However, because the glaze of the traditional glazed ceramic tile is a layer of glass, its surface hardness and wear resistance are not high enough, so it cannot Durable
Moreover, there is a difference in thermal expansion between the ceramic tile body and this layer of glaze, so there will be deformation in the later stage, and even defects such as cracking and falling off of the glaze surface

Abstract

The self-release glaze inducer, the self-release glaze ceramic tile and the preparation method thereof of the present invention focus on the formulation of the green body and the self-release glaze inducer without making significant changes to the production process of the existing ceramic tile. Adjust and optimize the spray amount, so that the surface of the prepared product is smooth and delicate, with slight unevenness. The surface gloss is measured with a WGG60‑E4 gloss meter to be 4-8, and the cross section of the product is observed with a 30 times magnifying glass. The glaze boundary layer, the product has good flatness, high strength, strong stain resistance, clear and natural pattern texture, bright color, realistic stone imitation, no pinholes, bubbles and other defects. Because the product does not need glazing, and the surface after high temperature calcination fully achieves the performance and decorative performance of glazed ceramic tiles, thus reducing the processing links of traditional glazed ceramic tiles and saving resources; at the same time, this technology has strong universality. It is easy to promote in the industry.

Description

Technical field: [0001] The invention relates to the technical field of preparation of glazed tiles, in particular to a self-releasing glaze inducer, a self-releasing glaze ceramic tile and a preparation method thereof. Background technique: [0002] The preparation of traditional glazed ceramic tiles is to apply a layer of glaze on the ceramic body and calcined at high temperature, and this layer of glaze is based on the performance requirements of the body, using natural mineral raw materials and some chemical raw materials in proportion Coordination, a glossy glassy layer that melts under the action of high temperature and covers the surface of the green body. This layer of glaze can improve the surface properties of the green body, improve the performance of the ceramic tile product, and increase the aesthetic feeling of the product. However, because the glaze of the traditional glazed ceramic tile is a layer of glass, its surface hardness and wear resistance are not hig...
