Nano composite antibacterial powder and application thereof in ceramic tea set

Abstract

The invention provides nano composite antibacterial powder and application thereof in a ceramic tea set. The nano composite antibacterial powder comprises nano metal oxide, silver-doped nano bismuth tungstate and a silver-loaded antibacterial agent. The invention also provides an antibacterial and antiviral glaze, an antibacterial and antiviral tea set and a preparation method of the antiviral tea set. The nano composite antibacterial powder disclosed by the invention has good antibacterial and antiviral properties through the synergistic effect of the nano metal oxide, the silver-doped nano bismuth tungstate and the silver-loaded antibacterial agent. the ano composite antibacterial powder is added into ceramic glaze, and after spraying and calcining, blank glaze with antibacterial and antiviral effects can be formed on the surface of a tea set, so that the overall antibacterial effect of the tea set is realized, the antibacterial time is relatively long, and the strength, wear resistance and appearance of the tea set are not influenced; and the preparation method of the antibacterial and antiviral tea set is simple, efficient, energy-saving and environment-friendly, does not need an additional treatment process, and is very high in application value.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics, in particular to a nanocomposite antibacterial powder and its application in ceramic tea sets. Background technique [0002] China is the hometown of tea. It has a history of at least several thousand years since the discovery and drinking of tea, and a tea culture has gradually formed. Tea sets can be divided into clay tea sets, porcelain tea sets, lacquer tea sets, glass tea sets, and bamboo and wood tea sets according to their materials. Among them, ceramic tea sets are widely used in daily life. Ceramic tea sets are special utensils for brewing and drinking tea made of kaolin and purple clay as raw materials, including ceramic teapots, ceramic covered bowls, ceramic teacups, ceramic tea trays, ceramic saucers and ceramic tea washers. [0003] As a utensil that is in direct contact with beverages, people have increasingly extensive demands on the functionality and safety of tea set...

AI Technical Summary

Problems solved by technology

However, the preparation process of this tea set is relatively complicated, the energy consumption is relatively large, and its antibacterial coating is easily affected by the external environment and human factors, etc., the adhesion is poor, and the antibacterial performance is not durable

[0005] CN111517828A discloses a nano antibacterial tea set and its manufacturing process. The antibacterial effect is achieved by applying a common glaze layer and a nano antibacterial glaze layer on the biscuit, but the nano antibacterial glaze layer is only arranged on the inner wall of the ceramic teapot and ceramic teacup. In general, the overall antibacterial effect cannot be achieved, and the glaze is applied twice, the process is complicated, the operation is difficult, and the overall structure of the tea set is also relatively complicated, requiring special production equipment, which increases the production cost

[0006] At present, the existing antibacterial tea sets often have the problems of being unable to achieve overall antibacterial and complex preparation processes
