[0004] CN 102765930A discloses a method for manufacturing antibacterial ceramic tiles. Kaolin, feldspar, and china clay are used as raw materials to make blanks. One side of the ceramic tile body is engraved with grid-shaped wire grooves formed by the vertical intersection of horizontal and vertical lines. Place nano-silver wire, then make glaze slurry with diatomite powder, quartz powder, metal silver powder and color powder, and glaze the tile body, and then fire it to form antibacterial tiles. In this method, the amount of silver used is large. , the cost is high, and it is easy to fall off, so the application prospect is limited
CN109293338A discloses a negative ion antibacterial ceramic tile and its production process. The antibacterial ceramic tile includes an embryo body, a bottom glaze and a t

Abstract

The invention provides an antibacterial and mildew-proof ceramic tile and a preparation method thereof. The antibacterial and mildew-proof ceramic tile comprises a green body material, glaze and antibacterial agents, the glaze comprises feldspar, alkali metal carbonate, silver oxide and rare-earth metal oxide, and the antibacterial agents comprise nano-zinc oxide. The method includes the steps: pressing the green body material to obtain a ceramic tile green body; spraying the glaze to the surface of the ceramic tile green body and then sintering the ceramic tile green body to obtain a green ceramic tile; performing post-treatment on the green ceramic tile by the aid of solution containing the antibacterial agents to obtain the antibacterial and mildew-proof ceramic tile. The silver oxide and the rare-earth metal oxide serve as ceramic tile glaze components, silver oxide particles are fixed by forming a stable compound, silver loss in the use process is avoided, the antibacterial agentsare added into an antibacterial ceramic tile glaze layer to form negative-valence silver ions with excellent bactericidal activity, the antibacterial agents serve as photocatalysts participating in generation of various antibacterial groups, and antibacterial persistence of the surface of the ceramic tile is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of ceramic processing, and relates to an antibacterial and mold proof ceramic tile and a preparation method thereof. Background technique [0002] Ceramic tiles are an important type of ceramic products, which are mainly building or decorative materials obtained by grinding, mixing, pressing, glazing, and sintering metal oxides and semi-metal oxides. When they are used in hospitals, restaurants and other places and homes In the kitchen, bathroom and other occasions, traditional ceramic tiles do not have the functions of decontamination, deodorization, sterilization, and self-cleaning, which often cause harm to human health. Therefore, ceramic tiles with antibacterial, anti-mildew, and self-cleaning functions have emerged. [0003] Antibacterial ceramic tile is a product that combines ceramic technology and antibacterial technology. While maintaining the original functions and decorative effects of ceramic products,...
