The invention discloses a preparation method of an inorganic foaming building insulation board, which is prepared by foaming and molding raw materials of modified expanded perlite, silicon dioxide aerogel, hollow vitrified micro bubbles, halloysite nanotubes, a mixed flame retardant, a mixed cementing material, water and an inorganic foaming agent. The heat-insulating board has excellent temperature stability and chemical stability, and has the characteristics of no cracking, no falling, energy conservation, environmental protection, no pollution, good fireproof and non-combustible safety, high strength and the like; the heat-insulating material has the advantages of simple and convenient construction, short construction period, good quality and wide application range, and can be applied to various building outer walls, fireproof isolation belts and roofs. |
