Heat-insulation foamed ceramic plate and preparation method thereof

The invention discloses a heat insulation foamed ceramic plate and a preparation method thereof, wherein the heat insulation foamed ceramic plate is prepared from the following raw materials in percentage by weight: 60-80% of solid waste residue, 10-25% of kaolin, 10-20% of black mud and 1-3% of plasticizer, wherein the plasticizer comprises one or the combination of a plurality of ceramic polishing waste residues, steel slag and aluminum slag; the ceramic polishing waste residue comprises the following components in percentage by weight: 65-75% of SiO2, 15-25% of Al2O3, 2-4% of CaO, 1-3% of MgO, 1-3% of K2O and 2-4% of Na2O; the steel slag comprises the following components in percentage by weight: 10-20% of SiO2, 1-5% of Al2O3, 30-40% of CaO, 5-10% of MgO, 0.2% of K2O and 0.1% of Na2O; and the aluminum slag comprises the following components in percentage by weight: 0.5% of SiO2, 55-65% of Al2O3, 2% of CaO, 1% of MgO, 0.05% of K2O and 2.5% of Na2O. The heat insulation foamed ceramic plate which is produced by the method has the advantages of building energy conservation, heat preservation and insulation, fire resistance, dampproofness, acid and alkaline corrosion resistance, long service life and the like.
