Antifouling ceramic tile and preparation process thereof

The invention relates to the technical field of ceramic tiles, in particular to an antifouling ceramic tile and a preparation process thereof. The preparation process comprises the following preparation steps: polishing the surface of the ceramic tile; waxing the surface of the ceramic tile, wherein wax A is at least applied to the surface of the ceramic tile during waxing; the wax A comprises the following raw materials in parts by weight: 15-20 parts of silica sol, 64-76 parts of a solvent, 1-5 parts of a grinding aid with the boiling point being greater than or equal to 260 DEG C, 3-10 parts of an antifouling additive and 1-5 parts of a coupling agent. Wax A, wax B and wax C are sequentially applied to the surfaces of the ceramic tiles, tiny and loose holes formed after the surfaces of the ceramic tiles are polished can be filled with the wax A, and the surfaces of the ceramic tiles are smoother; the wax B permeates into gaps of the wax A to block smaller micropores in the surface of the ceramic tile, so t
