Inorganic lightweight aggregate heat preservation and insulation board and preparation method thereof
The invention discloses an inorganic lightweight aggregate heat preservation and insulation board and a preparation method thereof and belongs to the technical field of building materials. The board is prepared from the following raw materials in parts by mass: 100 parts of cement, 35-38 parts of pulverized fuel ash, 5-8 parts of glass microspheres, 70-80 parts of medium sand, 0.5-1 part of an efficient water reducing agent, 0.1-2 parts of a water-proofing agent, 0.2-1 part of a foaming agent, 7-10 parts of an exciting agent, 30-35 parts of water, 20-40 parts of vermiculite powder, 10-15 parts of expanded perlite and 30-45 parts of TiO2-B2O3-SiO2 sol. The heat preservation and insulation board is high in fireproof performance, excellent in mechanical strength, low in heat conductivity coefficient, low in water absorption and moisture absorption and high in softening coefficient; the service life of the heat preservation and insulation board is as long as the service life of the building; the problems of the water resistance of similar inorganic lightweight heat preservation and insulation boards can be effectively solved.
