The invention discloses a water-resistant moistureproof ceramic tile and a preparation method thereof. The water-resistant moistureproof ceramic tile is prepared from the following raw materials in parts by weight: 20-30 parts of zebra stone, 15-25 parts of soil of an east wall, 18-27 parts of chromium slag, 5-10 parts of magnesium hexafluorosilicate hexahydrate, 17-26 parts of hard boron calcium stone, 14-22 parts of coal slime, 16-24 parts of refining slag, 15-25 parts of spinel, 11-19 parts of fluorgypsum, 20-30 parts of feldspar tailings, 10-15 parts of edible seaweed powder, 19-28 parts of apatite, 13-21 parts of lithium mica slag and 5-10 parts of high temperature activated bamboo charcoal powder. The ceramic tile is added with the raw materials of zebra stone, the soil of the east wall, magnesium hexafluorosilicate hexahydrate, edible seaweed powder and high temperature activated bamboo charcoal powder, so that water resistance and moistureproof property of the ceramic tile can be improved, antibacterial and mouldproof effects can also be achieved, and weather resistance and mechanical properties of the ceramic tile can also be improved; and compared with traditional ceramic tiles, the ceramic tile disclosed by the invention has excellent water resistance, moistureproof property, antibacterial property, corrosion resistance and mechanical properties.
