USE - As high porosity foamed ceramic insulation board. ADVANTAGE - The insulation board has extremely high compressive strength, extremely low thermal conductivity coefficient and volume density, excellent insulation performance and high flame retardant level which will not burn. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the high-porosity foamed ceramic insulation board, involving (i) mixing electrolytic manganese residue, potassium-sodium feldspar, dolomite, chlorite, serpentine, gangue, silicon carbide and fluorite, adding to a ball mill tank, adding portion of water, performing wet ball mill for 12-16 hours to obtain slurry, (ii) adding red mud, basalt fiber, graphene, alumina, terbium oxide, antimony oxide, boric acid, bentonite, sodium bicarbonate, chitosan, sodium hexametaphosphate and stabilizer to remaining water, mechanical stirring at 200-400 rpm for 30-50 minutes, slowly adding to the slurry, mechanical stirring at 500-600 rpm for 5-10 minutes, add carboxymethyl cellulose, and continuously stirring for 10-20 minutes to obtain a mixture, and (iii) filling the mixture into a mold, pressing with a hydraulic brick machine under a pressure of 8-12MPa to form a blank plate, placing the blank plate in a drying cabinet at 40-45 degrees C to dry to a moisture content of less than or equal to 10%, transferring to a ceramic sintering furnace, increasing the temperature in first-stage to 140-160 degrees C for 1-3 hours, increasing the temperature in second-stage to 1180-1250 degrees C, sintering for 3-5 hours, naturally cooling to room temperature, removing the mold, cutting and polishing to obtain the product.
