Water-resistant foamed gypsum thermal-insulation material and preparation method thereof
The invention discloses a water-resistant foamed gypsum thermal-insulation material which is prepared from the following raw materials in parts by weight: 100 parts of modified desulfurized building gypsum powder, 5-10 parts of polymer composite emulsion, 0.1-0.5 part of polyvinyl alcohol fiber and 40-60 parts of mixing water. The modified desulfurized building gypsum powder is prepared by mixing the following raw materials in parts by weight and grinding in a ball mill for 0.5-1 hour: 100 parts of building desulfurized gypsum powder, 2-10 parts of sodium aluminate, 1-5 parts of natural base, 1-3 parts of sodium citrate, 5-20 parts of rice hull ash and 1-3 parts of trisodium phosphate. Besides, the invention also discloses a preparation method of the water-resistant foamed gypsum thermal-insulation material. The water-resistant foamed gypsum thermal-insulation material has the advantages of light weight, high strength, thermal insulation, fire resistance, water resistance, short manufacturing period, low cost and the like, can be directly used for internal wall thermal insulation and external wall thermal insulation of a building, and has certain carrying capacity.
