The preparation process includes steps of: 1) mixing the raw materials including, by weight, 18-22 parts of black mud, 18-22 parts of pressure-discharged mud, 55-65 parts of waste residue of refractory bricks, 0.03-0.05 parts of PVA, 0.4-0.5 parts of lignin, 0.75-0.81 parts of sodium metasilicate and 43-48 parts of water, ball-milling the mixture to form slurry, and spray-drying the slurry to obtain a high-temperature brick powder material; 2) placing the high-temperature brick powder material in a pressing mould to press-shape the high-temperature brick powder material, and sintering the material in a kiln to obtain a finish product. The high-temperature brick not only has high-temperature fireproof effect but also is higher in strength, can be repeatedly used, is greatly reduced in preparation cost, is more environment-friendly and energy-saving, and has simple preparationprocess.
