Abstract

The invention discloses a preparation method of anti-bacterial ceramic glaze. The preparation method comprises the following steps that (1) in parts by mass, 0.5-1.5 parts of potassium hexafluorosilicate is added into water to be dissolved at the mass volume ratio of 5 g to 100 mL, 1-3 parts of anti-bacterial powder is added and dispersed evenly, the mixture is heated at the temperature of 90-110DEG C till the solid-liquid ratio being 80-90%, and anti-bacterial slurry is obtained; (2) in parts by mass, 60-70 parts of silicon dioxide, 3-8 parts of aluminum oxide, 5-15 parts of diboron trioxide, 5-10 parts of calcium oxide, 0.5-1.5 parts of magnesium oxide, 10-20 parts of sodium oxide, 1-3 parts of potassium oxide, 0.8-1.5 parts of cobalt oxide, 1.5-2.5 parts of ferric oxide and 0.3-0.8 part of manganese oxide are blended to be uniformly mixed and ball-milled for 3-5 hours, then sieved by a 90-110 mesh sieve, and the mixed material is obtained; and (3) the mixed material is added into the anti-bacterial slurry and stirred to be uniform, and the anti-bacterial ceramic glaze is obtained. The ceramic glaze can achieve the excellent and durable anti-bacterial performance by adding the anti-bacterial powder, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of ceramic material preparation, in particular to a preparation method of antibacterial ceramic glaze. Background technique [0002] With the development of society and the improvement of people's living standards, people's requirements for the quality of life are getting higher and higher, people's awareness of environmental protection is getting stronger, and antibacterial materials are getting more and more attention. Antibacterial ceramics are a new type of functional material to protect the environment. It is the product of the combination of antibacterial agents, antibacterial technology and ceramic materials, as well as the product of the combination of material science and microbiology. While maintaining the original function and decorative effect of ceramic products, it increases the functions of disinfection, sterilization and chemical degradation. Therefore, it is widely used in industries such a...
