Problems solved by technology

Among them: the first kind of antibacterial ceramics, because the antibacterial material is directly added to the ceramic tile body or glaze and fired, and its antibacterial active ingredients are coated in the body or glaze, its antibacterial effect will be greatly reduced
The second antibacterial material is sprayed on the surface of ceramic tiles and then fired. After high-temperature heat treatment, the structure of the antibacterial material is destroyed, and the antibacterial effect is significantly reduced. A certain amount of antibacterial material is attached to the surface of ceramic tiles. During high-temperature heat treatment, it is easy to react with the glaze surface and affect the surface decoration. Effect
The third type adopts low-temperature heat treatment. The antibacterial layer has weak bonding force with the glaze surface. In practical application, the antibacterial layer is easy to fall off, and the antibacterial durability is poor.
However, the above-mentioned scheme mainly has the following problems. First, zinc oxide or silver oxide is used as the antibacterial material in the antibacterial and antifouling liquid adopted in the prior art. Or silver ion salt solution, in the process of washing, it is easy to wash off the antibacterial material, resulting in poor antibacterial persistence

Abstract

The invention relates to the technical field of new building ceramic materials, and particularly discloses a composite process antibacterial ceramic tile and a preparation method thereof. The composite process antibacterial ceramic tile comprises a green body layer and an antibacterial glaze layer, glaze of the antibacterial glaze layer contains a first antibacterial agent, and surface micropores of the antibacterial glaze layer are filled with an antibacterial antifouling agent; and the first antibacterial agent comprises zinc silicate and / or zinc aluminate, the antibacterial antifouling agent contains a second antibacterial agent, and the second antibacterial agent comprises nano zinc phosphate and / or nano zinc zirconate. The preparation method comprises the following steps: preparing the green body layer, preparing the antibacterial glaze slip, spraying the antibacterial glaze slip on the surface of the green body layer, sintering to obtain a semi-finished product, polishing the semi-finished product, and polishing the surface of the semi-finished product by using an antibacterial antifouling agent to obtain the antibacterial ceramic tile. According to the antibacterial ceramic tile, a composite antibacterial technology combining in-glaze antibacterial and glaze layer surface micropore antibacterial is adopted, efficient and lasting antibacterial of a ceramic tile product is achieved, antibacterial components do not affect permeability of a glaze surface, and the antifouling performance of the glaze surface can be achieved.
