Problems solved by technology

TiO2antibacterial agent coated antibacterial ceramics have problems of bonding with the green body, easy to fall off, uneven film thickness, strict requirements for coating equipment, etc.
How to improve the photocatalytic efficiency of photocatalytic antibacterial ceramics under weak light, the bonding force between the coating film and the glaze surface is not enough, the coating film needs special equipment and the cost is high, and solve the problem that the life of the film aging does not match the service life of the ceramic
[0005] CN210659053U discloses a kind of negative ion self-cleaning antibacterial ceramic tile, by alternately distributing antibacterial layer by nanometer TiO2 antibacterial layer, silver-based antibacterial layer to form antibacterial layer Although the ceramics prepared by this method have antibacterial ability and anion self-cleaning antibacterial performance under light and dark conditions, this kind of anion self-cleaning antibacterial ceramic tile has many coating layers, and the thickness of each layer is limited. Not easy to control, no solution to film adhesion problem and antibacterial persistence problem
[0006] CN111393188A discloses a kind of antibacterial glaze for ceramic sanitary ware, ceramic sanitary ware and its preparation method, through the method of double layer glazing, only add antibacterial agent in surface glaze , to reduce the use of antibacterial agents and thus reduce costs. The effective antibacterial component of this method is nano-silver. Ceramics can effectively kill a variety of bacteria in a short time, but the process is more complicated, and it does not solve the slow-release problem of silver. Wear-resistant Poor durability and antibacterial durability, long-term use will reduce the antibacterial effect of ceramics

Abstract

The invention provides antibacterial and antiviral glaze, antibacterial and antiviral ceramic and a preparation method of the antibacterial and antiviral ceramic. The antibacterial and antiviral glazecomprises nano composite antibacterial powder, nano aluminum oxide, a dispersing agent, a coupling agent and basic glaze, the nano composite antibacterial powder is prepared from the following components in parts by mass: 10 to 25 parts of nano metal oxide; 5 to 10 parts of silver doped nanometer bismuth tungstate; and 70-80 parts of a nano-silver antibacterial agent. When the ceramic is in contact with microorganisms such as bacteria, molds and viruses in the use process, the long-acting antibacterial, mildew-proof and antiviral effects are achieved, the appearance, strength and wear resistance of the ceramic are not affected, no harmful ingredients are generated in the use process, and the environment is not polluted.

Description

technical field [0001] The invention belongs to the field of ceramics, and relates to a glaze and ceramic tiles, in particular to an antibacterial and antiviral glaze, an antibacterial and antiviral ceramic and a preparation method thereof. Background technique [0002] Antibacterial ceramics mainly refer to ceramic parts made by adding inorganic antibacterial agents to the glaze or glaze of sanitary ware ceramics and ceramic tiles, or impregnating, spraying or rolling on the surface. At present, antibacterial ceramics are mainly divided into two types: metal ion doped antibacterial ceramics and photocatalytic antibacterial ceramics. Among them, metal ion-doped antibacterial ceramics are directly fired by adding antibacterial agents containing silver, zinc, copper and other metal ions directly into ceramic glazes; photocatalytic antibacterial ceramics are made by sol-gel method or impregnation. The pulling method coats titanium dioxide or zinc oxide antibacterial film on th...
