Abstract

The invention discloses an antibacterial ceramic tile and a preparation method thereof. The antibacterial ceramic tile comprises a green body layer, an infrared antibacterial cover glaze layer, a fancy glaze color glaze layer and a transparent protective glaze layer from top to bottom, wherein the infrared antibacterial cover glaze layer is prepared from the following raw materials: basic cover glaze, an infrared antibacterial material, a suspending agent, a peptizing agent and water; the infrared antibacterial material is prepared by sintering the following raw materials: 97-99% of potassium-sodium stone powder and 1-3% of rare earth oxide; the rare earth oxide is prepared from at least two of La2O3, CeO2, Pr8O11, Nd2O3, Sm2O3, Gd2O3, Dy2O3 and Y2O3. According to the invention, the antibacterial functional layer is isolated from the external environment, the antibacterial durability of the tile body is improved, the antibacterial ceramic tile in the scheme can play an antibacterial role in a non-contact mode, and compared with common antibacterial tiles on the market, the antibacterial ceramic tile has a wider application space, has antibacterial and infrared radiation effects, and also takes the strength, the water absorption rate, the glaze quality and the like of the ceramic tile into consideration, and the antibacterial ceramic tile with better quality is obtained.

Description

technical field [0001] The present application relates to the technical field of ceramic tiles, in particular to an antibacterial ceramic tile and a preparation method thereof. Background technique [0002] As an important decorative material for daily home, ceramic tile is closely connected with people's life. Because of its characteristics of easy cleaning, high temperature resistance and rich glaze color, it is widely used in the decoration industry. With the continuous progress of modern technology, the market began to study antibacterial tiles, which can continue to inhibit or kill bacteria and other microorganisms during the use of tiles. [0003] At present, the antibacterial ceramic tile products on the market are mainly concentrated in the following categories: (1) using metal ion loading as an antibacterial agent to achieve antibacterial by slowly releasing metal ions such as silver and zinc to destroy the bacterial cell structure; (2) using light Catalytic antiba...
