Abstract

The invention provides rare earth added antibacterial ceramic glaze and a preparation method thereof and relates to the field of ceramic preparation. The ceramic glaze mainly comprises the following raw materials in parts by weight: 25-45 parts of silicon dioxide, 5-13 parts of aluminum oxide, 3-5 parts of deep sea mineral mud, 3-6 parts of magnesium oxide, 2-6 parts of copper oxide, 1-5 parts of zinc oxide, 4-8 parts of zirconium silicate, 1-3 parts of titanium dioxide, 3-9 parts of opal shale, 0.2-0.5 part of polyethylene glycol, 2-7 parts of sodium metaphosphate, 2-12 parts of rare-earth metal oxide and 67-95 parts of organic solvents; and the raw materials also comprise 2-6 parts of silver nitrate. The rare earth added antibacterial ceramic glaze provided by the invention is lasting in antibacterial time and high in efficiency, and other performances of ceramic products are not influenced.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a rare earth-added antibacterial ceramic glaze and a preparation method thereof. Background technique [0002] The ceramics we use every day are generally covered with smooth and smooth clothes, especially daily-use ceramics, which are more particular about "clothes". Some are as white as jade, and some are colorful and very beautiful. This kind of ceramic clothes is called "glaze". Ceramic glaze has physical and chemical properties similar to glass state, impermeable, smooth and shiny, not easy to stain, and can improve the mechanical strength, thermal stability and chemical stability of the product. Various decorations can also be used on the glazed surface to enhance the artistic effect of the product. [0003] Ceramics are widely used, among which ceramic products are more in demand in life, such as sanitary ware, tableware and so on. With the improvement of l...
