Antibacterial glaze, antibacterial brick and preparation method of antibacterial brick

Abstract

The invention discloses an antibacterial glaze, an antibacterial brick and a preparation method of the antibacterial brick. The antibacterial glaze comprises the following raw materials in parts by weight: 25-35 parts of albite, 10-15 parts of potassium feldspar, 5-7 parts of kaolin, 5-15 parts of quartz, 3-5 parts of aluminum oxide, 5-10 parts of talc, 5-7 parts of zinc oxide, 10-20 parts of dolomite, 5-15 parts of wollastonite, 7-12 parts of strontium carbonate, 3-5 parts of barium carbonate and 4-6 parts of nano antibacterial powder. The antibacterial glaze is prepared through crushing, uniform mixing and ball milling, and then the surface of a green body layer is coated with the antibacterial glaze, so the antibacterial brick disclosed by the invention is prepared. The antibacterial effect of the antibacterial glaze reaches 99%, the firing temperature range is wide during ceramic tile preparation, and a prepared ceramic tile glaze layer is high in mechanical strength, almost free of bubbles, good in layering sense and capable of being suitable for a low-water-absorption green body and a high-water-absorption green body at the same time.

Description

technical field [0001] The invention belongs to the field of glazes, and in particular relates to an antibacterial glaze, an antibacterial brick and a preparation method thereof. Background technique [0002] With the continuous improvement of people's requirements for the quality of life, the antibacterial performance of ceramic products has attracted more and more attention, and the key lies in antibacterial glazes; The mechanical strength of the glaze layer is insufficient, the brightness is insufficient, and it contains air bubbles. The firing temperature range is narrow during firing, which affects the yield rate, increases the production cost, and reduces the production efficiency. In addition, adding nanomaterials to the glaze can strengthen the combination of the glaze and the green body, and most of the antibacterial materials are nanomaterials, but at the same time, there is also the problem that the fluidity of the glaze will be reduced after adding nanomaterials....

Problems solved by technology

[0002] With the continuous improvement of people's requirements for the quality of life, the antibacterial performance of ceramic products has attracted more and more attention, and the key lies in antibacterial glazes; The mechanical strength of the glaze layer is insufficient, the brightness is insufficient, and it contains air bubbles. The firing temperature range is narrow during firing, which affects the yield rate, increases production costs, and reduces production efficiency.

In addition, adding nanomaterials to the glaze can strengthen the combination of the glaze and the green body, and most of the antibacterial materials are nanomaterials, but at the same time, there is also the problem that the fluidity of the glaze will be reduced after adding nanomaterials. This will seriously affect the coating of the glaze and affect the yield
