The invention mainly relates to the technical field of ceramic tile processing, and discloses a self-cleaning ceramic tile. The self-cleaning ceramic tile is prepared from the following raw materials:52-54 parts of lithium-based montmorillonite, 33-35 parts of modified bentonite, 24-26 parts of talc powder, 15-17 parts of waste ceramics, 10-12 parts of lightweight calcium carbonate powder, 1.7-1.9 parts of nano titanium dioxide, 1.2-1.4 parts of nano anion powder, and 1.1-1.3 parts of a surface treating agent. The self-cleaning ceramic tile provided by the invention has high strength, strongwear resistance, glossiness of 64.3 degrees, good anti-fouling self-cleaning effects, increases types of ceramic tiles on the market, and meets the needs of consumers; the lithium-based montmorillonite, the modified bentonite and the talc powder are mixed, the mixed material is crushed, so that the pulverization degree of the raw materials is improved, and the strength and wear resistance of the ceramic tile are increased; and the lithium-based montmorillonite has better fluidity and adhesion, so that the flatness and glossiness of the ceramic tile can be improved, the strength and glossinessof the ceramic tile can be increased, and the ceramic tile grade can be improved.
