Abstract

The invention relates to cold ceramic glaze with sterilization and antibacterial functions and a preparation method thereof. The cold ceramic glaze includes the following raw materials in parts by weight: 1-8 parts of tetrabutyl titanate, 1-8 parts of tetraethoxysilane, 1-8 parts of absolute ethyl alcohol, 1-4 parts of metakaolin, 1-4 parts of aluminum oxide, 1-3 parts of water glass, 0.5-2 parts of sodium hydroxide and 1-10 parts of water. The preparation method comprises the steps of evenly stirring the raw materials into slurry and coating the slurry are evenly coated on a ceramic body, and the cold ceramic glaze is formed on the surface of the ceramic body after the slurry is dry. The cold glaze provided by the invention is suitable for retouching a variety of ceramic bodies, a good intermediate layer is formed after glazing, the cold glaze is well combined with the body and has excellent mechanical properties, moreover, the ceramic glaze is smooth in surface, tephrosious and transparent in color and luster and free of defect on the surface, and is capable of meeting the market demands.

Description

technical field [0001] The invention relates to a ceramic cold glaze with antibacterial and sterilizing functions and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] "Glaze" is a glossy glass-like thin layer covering the surface of the ceramic body, and its function is to improve the physical and chemical properties of the body surface. Generally, the surface of the ceramic body is loose, porous, rough and dull, easy to stain and absorb moisture, etc., which affect the aesthetics, sanitation and mechanical properties of the product, and the use of glaze can overcome these shortcomings and improve the performance of the product. First of all, "glaze" can improve the whiteness and gloss of the surface of ceramic products, and play a decorative role by increasing color and forming colorful patterns; secondly, it can improve the hardness of the product and increase its thermal stability; then, in terms of chemical properti...
