Nano antibacterial corrosion-resistant ceramic and preparation method thereof

Abstract

The invention discloses a nano antibacterial corrosion-resistant ceramic which comprises an antibacterial glaze layer on the surface of corrosion-resistant ceramic; the antibacterial glaze layer is composed of a ground glaze layer and an antibacterial layer; the antibacterial layer is formed by loading a composite antibacterial agent on nano calcium carbonate; wherein the nano calcium carbonate loaded composite antibacterial agent comprises a nano calcium carbonate carrier and a composite antibacterial agent, the nano calcium carbonate loaded composite antibacterial agent is accumulated at theupper part of a glaze layer, the antibacterial effective component of the composite antibacterial agent is nano antibacterial oxide, and the nano antibacterial oxide is nano magnesium oxide and nanozinc oxide. According to the invention, the nano antibacterial material is added to the outermost surface of the ceramic, excellent antibacterial effect is achieved; the nano calcium carbonate is introduced into the antibacterial layer to serve as a porous carrier of the nano antibacterial agent, so that the adhesive force of the nano antibacterial agent can be remarkably improved, the antibacterial performance is more durable and efficient, meanwhile, the surface appearance decoration effect of the ceramic is not affected, and the antibacterial ceramic can be widely applied to the fields of architectural decoration, domestic ceramics and the like.

Description

Technical field [0001] The invention relates to the technical field of ceramics, in particular to a nano antibacterial and corrosion-resistant ceramic and a preparation method thereof. Background technique [0002] With the impact of the global spread of the new crown pneumonia epidemic in 2020, people are paying more and more attention to the standard of living hygiene and health, and the demand for antibacterial and sterilization products continues to increase. Antibacterial series products are very extensive. As far as the construction field is concerned, ceramic tiles are products used in buildings, family rooms and public places. It is closely related to everyone's life and health, especially in toilets, kitchens, bathrooms, etc. The place where all kinds of germs grow and spread. At present, antibacterial ceramic products with antibacterial function have entered the market. People have higher and higher requirements for the quality and use effect of antibacterial ceramics. ...

AI Technical Summary

Problems solved by technology

At present, antibacterial ceramic products usually add antibacterial agents to the glaze. Because the antibacterial ceramics are fired directly into the ceramic body or glaze, the antibacterial active ingredients are coated in the body or glaze, and its antibacterial effect and durability will be greatly reduced

At present, most antibacterial ceramic products rarely have corrosion resistance except for certain antibacterial effects.
