Applique antibacterial ceramic cutter

Abstract

The invention relates to an applique antibacterial ceramic cutter, and belongs to the technical field of daily ceramics. The cutter comprises a cutter blank, and is characterized in that the outer surface of the cutter blank is covered with a layer of antibacterial self-cleaning ceramic glaze; the antibacterial self-cleaning ceramic glaze is prepared from the following raw materials in percentageby weight: 15 to 30 percent of quartz, 20 to 40 percent of feldspar, 10 to 20 percent of borax, 6 to 18 percent of boric acid, 3 to 7 percent of barium carbonate, 2 to 5 percent of sodium carbonate, 4to 9 percent of bentonite, 0 to 6 percent of phosphorus pentoxide, 10 to 20 percent of zinc oxide, 0 to 6 percent of titanium oxide, 1 to 5 percent of strontium carbonate, 0 to 4 percent of lithium carbonate, 1 to 4 percent of cooked steatite, 1 to 6 percent of alumina, and 1 to 4 percent of rare-earth; and the rare-earth is one or a mixture of arbitrary two of the cerium oxide, the cerium lanthanum chloride and the lanthanum nitrate. The cutter has the effect of antibacterial self-cleaning, has beautiful appearance, and is suitable for the occasion of high-grade application.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics, and in particular relates to a decal antibacterial ceramic tableware and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's awareness of environmental protection has been continuously strengthened. At the same time, due to the deterioration of the environment and global warming, bacteria breed, and the infection and incidence of infectious diseases are gradually increasing. In particular, the raging SARS virus and bird flu have made people realize the importance of purifying the home environment. In the prior art, the daily practical tableware and knives are basically metal. If they are not cleaned in time or thoroughly after use, bacteria will easily breed. [0003] At present, industrially developed countries have begun to promote antibacterial sanitary ceramic product...

Problems solved by technology

Its main shortcomings are: 1) antibacterial agents are generally used on the surface or glaze of ceramics, which limits its application field; 2) metal ions are exposed to the air for a long time, and are easy to change color due to oxidation; 3) there are heavy metal ions entering food The possibility of affecting its safety; 4) Poor anti-fungal properties; 5) Metal silver is mor
