Composite process antibacterial ceramic tile and preparation method thereof

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.

Description

technical field

[0001] The invention relates to the technical field of new building ceramic materials, in particular to a functional ceramic material, in particular to a compound process antibacterial ceramic brick and a preparation method thereof. Background technique

[0002] At present, for non-polished ceramic tiles, there are mainly the following types of antibacterial ceramics: the first is to directly add antibacterial materials to ceramic tiles and mix and fire them. The antibacterial agent generally uses silver phosphate. The second is to spray antibacterial materials on the surface of ceramic tiles. During its preparation, an antibacterial mixed salt solution is sprayed on the surface of transparent glaze to form an antibacterial layer, which is fired at high temperature. The third is to spray antibacterial materials on the surface of finished bricks, and then undergo low-temperature heat treatment to achieve antibacterial effects. Among them: the first kind of an...
