When using glazed tiles as floor decoration materials, there are high requirements for the wear resistance of glazes. Glazed tiles prepared from glazes with low wear resistance are easy to be scratched, and products with poor wear resistance can be used for a long time. After a long time, the gloss will decrease obviously, and the surface will be dull, which will seriously affect the appearance
At present, the surface hardness of polished glaze products on the market is below Mohs hardness 4, and the wear resistance level is generally at level 3 at 750 rpm. The wear resistance is difficult to meet the requirements of consumers.

[0040] A kind of wear-resisting glazed tile, prepared according to the following steps:
[0041] (1) According to the weight percentage, the frit powder is prepared according to the mineral composition of the frit powder in Table 2. After the melting temperature is 1520° C. for 30 minutes, the discharge water is cooled to form a frit, and the prepared frit is powdered and sieved, Dry and get the 100 mesh sieve for subsequent use;
[0042] (2) According to the percentage by weight, according to the raw material composition of the high-performance wear-resistant glaze in Table 1, and the mineral composition of the raw glaze powder in Table 2, take by weighing for subsequent use;
[0043] (3) Add the above raw materials to water ball mill for 9 hours to obtain a glaze slurry, control the fineness of 325 mesh to 1.2% mass fraction, and then stale for 49 hours to obtain a high-performance wear-resistant glaze.
[0044] (4) Replace the surface glaze in the existing production proce...

Abstract
The present invention relates to the technical field of architectural ceramics, in particular to a high-performance wear-resistant glaze and a preparation method thereof. The high-performance wear-resistant glaze, according to the weight percentage of raw materials, consists of raw glazepowder 65-75% and frit 25-35% powder; according to the percentage by weight, the raw glaze powder includes the following raw materials: albite 30-40%, calcined talc 12-16%, kaolin 4%-10%, calcite 10-15%, oxidation Zinc 2‑8%, Wollastonite 10‑15%, Corundum 10‑20% and BariumCarbonate 2‑8%. The purpose of the present invention is to propose a high-performance wear-resistant glaze and its preparation method. While the flatness of the polished glazed tiles produced by the glaze meets the requirements of the production process, the contradiction between the transparency of the glaze layer and the wear-resistant performance is solved, and the production process is completed. The finished polished glazed tile has greatly improved wear resistance, high flatness and good color development.
Description
technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a high-performance wear-resistant glaze and a preparation method thereof. Background technique [0002] Ceramic glazed tiles combine the advantages of porcelain glazed tiles and polished tiles. They are not only rich in patterns and images, but also have a smooth and bright surface. In the early days of their appearance, they were popular among consumers for their rich designs and patterns and clear texture levels. However, with the passage of time, some disadvantages of glazed tiles have gradually become prominent, the most prominent of which is the low wear resistance of the product, which makes the surface easy to wear. The wear resistance of glazed glazed tiles is a big problem that plagues the industry. When using glazed tiles as floor decoration materials, there are high requirements for the wear resistance of glazes. Glazed tiles prepared from glazes with l...
