Supersulphated foamed cement insulation board and preparation process thereof
The invention discloses a supersulphated foamed cement and an insulation board thereof, and preparation methods. The cement comprises raw materials composed of the following components by mass: 80 to 90% of slag, 10 to 15% of desulphurized gypsum, 0 to 10% of building gypsum, 0 to 10% of slaked lime and 0 to 10% of limestone. The insulation board comprises raw materials composed of the following components by weight: 2400 to 4000 parts of the cement, 140 to 1200 parts of fly ash, 1600 to 2400 parts of water, 20 to 60 parts of a foam stabilizer, 0 to 10 parts of a water reducer, 100 to 300 parts of a foaming agent and 0 to 30 parts of fiber. The invention has the following advantages: resource utilization of the desulfurized gypsum is realized; a great amount of industrial wastes like the slag and the fly ash are utilized; meanwhile, production process is energy-saving and environment-friendly; thus, good economic and environmental benefits are obtained. Moreover, the foamed insulation board provided by the invention has the characteristics of light weight, heat insulation, flame retardance, sound insulation and absorption, etc, and is low in production cost and simple in process.
