Abstract

The invention discloses an antifouling and antibacterial ceramic glaze, which is made of the following raw materials in parts by weight: 50-60 parts of basic glaze slurry, 7-9 parts of calcium oxide, 3-5 parts of calcium carbonate, and 4-6 parts of aluminum hydroxide 5 parts, 4-5 parts of antibacterial agent, 5-7 parts of nano-zinc oxide, 2-3 parts of sodium hexametaphosphate, 8-10 parts of phosphoric acid aqueous solution, 2-3 parts of yttrium nitrate aqueous solution; Preparation method of antibacterial ceramic glaze. In the present invention, an antibacterial agent is added to the basic glaze, and the antibacterial agent can be evenly distributed in the glaze, and the fired ceramics can continuously and slowly release silver ions in water to achieve a continuous antibacterial effect; Phosphoric acid aqueous solution and yttrium nitrate aqueous solution are used, so that the ceramics fired by the glaze have good hydrophobicity, and the dirt cannot be firmly adhered to the surface of the coating. When water droplets flow through the surface, the dirt can be washed away to achieve antifouling. effect; and the preparation process is simple, the conditions are easy to control, and the production cost is low.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, and in particular relates to an antifouling and antibacterial ceramic glaze and a preparation method thereof. Background technique [0002] Ceramics are various products made of natural clay and various natural minerals as the main raw materials through crushing, kneading, molding and calcination. Ceramic art has always occupied a relatively important position in various art cultures. As for ceramic art, the glaze is a key part. Generally speaking, the so-called ceramic glaze is a thin uniform glassy layer covering the surface of the ceramic body. For ceramic products, ceramic glazes can improve performance and play a decorative role. Since the microstructure of ceramic materials is composed of crystal phase, glass phase and pores, the final product has a porosity of 5% to 10% (volume). At the same time, the surface of ceramic materials has a certain lipophilicity. When pollutants come ...
