Problems solved by technology

However, in the daily use and scrubbing process, the surface of these ceramic products is often worn, and scratches are left on the surface of the ceramic product. In addition, it is also often in contact with water, acid or lye. The surface will have ion exchange, dissolution or adsorption effects with these media to varying degrees, which will reduce the glaze gloss of ceramic products, form a thin layer of interference color on the glaze surface, and even cause the glaze surface to sink, and dissolve some cations in the glaze. It is easy to leave traces on the surface of ceramic products, which greatly affects the appearance of ceramic glaze and the use of ceramic tiles, and will also cause ceramic tiles to become more and more prone to corrosion and damage, shortening the service life of ceramic tiles
However, the wear resistance and corrosion resistance of the existing ceramic glazes are not ideal, and cannot meet the needs in actual use.

Abstract

The invention belongs to the technical field of ceramics, and discloses a wear-resistant and corrosion-resistant ceramic glaze. Nano zirconium silicate in the formula can play wear-resistant, corrosion-resistant and hydrolysis-resistant roles. White corundum and zirconium oxide are used as wear-resistant agents, so that the wear resistance of the glaze is further improved, and the introduced whitecorundum has little influence on the firing temperature of the glaze. All the components coordinate with one another after being compounded, and the obtained ceramic glaze is high in effective component content and excellent in wear resistance and corrosion resistance and can be used for manufacturing ceramic products. Besides, the invention also discloses a preparation method of the ceramic glaze. The preparation method is simple in process, easily available in raw materials and low in cost, the wear resistance of the prepared ceramic tile glaze is effectively improved, meanwhile, the acid and alkali resistance and other properties of the material are greatly improved, acidic liquids such as cola, vinegar and carbonated beverages and alkaline liquids such as alkaline water, washing powder and baking soda can be easily wiped off, and the requirements of practical application can be met.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a wear-resistant and corrosion-resistant ceramic glaze and a preparation method and application thereof. Background technique [0002] Ceramic glaze is a material covered on the outer layer of the green body after melting inorganic powders such as silicates and oxides at high temperature. It has been widely used in the preparation of ceramic products, such as tableware, kitchen utensils, walls, floors, etc., with a long history. However, in the daily use and scrubbing process, the surface of these ceramic products is often worn, and scratches are left on the surface of the ceramic product. In addition, it is also often in contact with water, acid or lye. The surface will have ion exchange, dissolution or adsorption effects with these media to varying degrees, which will reduce the glaze gloss of ceramic products, form a thin layer of interference color on the glaze s...
