Abstract

The invention relates to the technical field of new building materials, in particular to a foamed ceramic heat preservation board, which is composed of the following raw materials in parts by weight:20-40 parts of coal gangue, 10-20 parts of iron tailings, 10-30 parts of fly ash, 5-15 parts of dolomite, 4-10 parts of silicon carbide, 3-9 parts of far infrared ceramic powder, 4-10 parts of calcined talc, 8-12 parts of perlite, 3-9 parts of calcium carbonate, 10-20 parts of epoxy resin powder, 2-4 parts of crack resistant fiber, 1-3 parts of brucite nanofibers, 7-15 parts of modified diatomaceous earth, and 2-4 parts of graphene. The invention takes solid wastes such as coal gangue, iron tailings, fly ash and the like as main raw materials, provides an effective solution for resource reuse,and makes the foamed ceramic heat preservation board have high mechanical strength. Pearlite enveloped with calcium carbonate and epoxy resin powder can increase the overall strength and aging resistance of the heat preservation board, reduce water absorption and improve impermeability. The heat preservation board has the effects of crack resistance, impermeability, heat preservation, flame retardancy, abrasion resistance and compression resistance through the mutual assistance of the raw materials.
