Problems solved by technology

But the glaze on the glazed tile is mainly glass phase, and the glass phase is not wear-resistant, so the glazed tile is easy to scratch
Not wear-resistant and prone to scratches have become a major problem for glazed tile manufacturers to solve
[0003] In order to solve this problem, the patent CN107399911A discloses a non-slip and wear-resistant glaze and its preparation method, which improves the wear resistance of the polished glaze layer by adding anti-slip and wear-resistant particles. In this way, the glaze layer has uneven permeability and The problem that the combination of wear-resistant particles and glass is not tight; patent CN106946460A discloses a kind of cordierite transparent wear-resistant glaze and its preparation method. Abrasion resistance, the problem of this method is that the refractive index of cordierite is relatively different from that of glass phase, the transparency effect is poor, and the hardness of cordierite is low, so the improvement of the wear resistance of glaze polishing is very limited

Abstract

The invention discloses a wear-resistant transparent glaze that is prepared from the following raw materials in percentage by weight: 3 to 7 percent of nanoscale anorthite, 20 to 30 percent of albite,18 to 28 percent of fused quartz, 6 to 10 percent of kaolin, 40 to 50 percent of transparent frit, 0.01 to 0.5 percent of dispersing agent and 0.01 to 0.1 percent of plasticizer. By introducing special raw material components such as nanoscale anorthite, fused quartz and transparent frit, the raw material components of the glaze can play a synergistic effect in the conventional fusing and firingprocess, so a large amount of anorthite crystalline phases can be efficiently generated, and then the hardness, wear resistance and light transmission performance of the glaze are effectively and synchronously improved.

Description

technical field [0001] The invention relates to the field of architectural ceramic materials, in particular to a wear-resistant transparent glaze, a wear-resistant glazed tile and a preparation method thereof Background technique [0002] Existing glazed tiles apply a layer of glaze with a transparent effect after firing (hereinafter referred to as glazed tiles) on the upper layer of the pattern, so that various exquisite patterns can be printed on the tile surface according to the pattern design, and fired. After polishing, the final product can present the characteristics of rich patterns and high gloss. Therefore, polished glazed tiles are very popular among consumers, and soon occupied most of the architectural ceramics market. However, the glaze on the glazed tiles is mainly a glass phase, and the glass phase is not wear-resistant, so the glazed tiles are easy to scratch. Not wear-resistant and prone to scratches have become a major problem for glazed tile manufacturer...
