The invention discloses an antifreeze wall brick, and the antifreeze wall brick is prepared from the following raw materials by weight: 30-40 parts of basalt, 5-8 parts of bamboo scraps, 20-25 parts of calcite, 20-30 parts of river silt, 10-20 parts of chalk soil, 50-100 parts of water, 5-10 parts of grinding wheel ash and 5-15 parts of montmorillonite by pre-activation, crushing, sealing aging, blank forming, drying and sintering. The preparation method is scientific, and the antifreeze wall brick is convenient to make, low in production cost and good in economic effect. The antifreeze wall brick is prepared from waste residues, energy is saved, the ecological environment is protected, the prepared antifreeze wall brick is strong in frost resistance, high in strength, fine and close in texture, free of crack and resistant to wear and tear, can be used under the condition of low temperature for a long time, and has strong construction adaptability.
