A kind of composite process antibacterial ceramic tile and preparation method thereof

Abstract

The invention relates to the technical field of new building ceramic materials, and specifically discloses a compound process antibacterial ceramic brick and a preparation method thereof. The composite process antibacterial ceramic tile includes a green body layer and an antibacterial glaze layer, the glaze of the antibacterial glaze layer contains a first antibacterial agent, and the micropores on the surface of the antibacterial glaze layer are filled with an antibacterial and antifouling agent; the first antibacterial agent includes silicic acid Zinc and / or zinc aluminate, the antibacterial antifouling agent contains a second antibacterial agent, and the second antibacterial agent includes nanometer zinc phosphate and / or nanometer zinc zirconate. The preparation method is as follows: first prepare the green body layer, then prepare the antibacterial glaze slurry and pour it on the surface of the green body layer, and make a semi-finished product after firing, polish the semi-finished product, and polish it with an antibacterial antifouling agent. Grinding to produce antibacterial ceramic tiles. The invention adopts the composite antibacterial process of antibacterial in glaze combined with microporous antibacterial on the surface of glaze layer to realize efficient and durable antibacterial of ceramic tile products, and the antibacterial components do not affect the permeability of the glaze surface, and can realize the antifouling performance of the glaze surface.

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...
