An environmentally friendly high-strength and high-barrier lightweight foam material for walls

Abstract

The invention relates to an environment-friendly high-strength high-barrier light foam material for walls.The environment-friendly high-strength high-barrier light foam material comprises, by weight, 4-8 parts of micron-calcium carbonate powder, 5-10 parts of saturated calcium chloride solution, 2-6 parts of desulfuration gypsum, 15-25 parts of Portland cement, 1-5 parts of tackified lamellar clay, 2-5 parts of micron-sodium bicarbonate powder, 3-6 parts of plasticizers, 2-4 parts of inorganic fibers and 15-25 parts of fiber mesh framework.The environment-friendly high-strength high-barrier light foam material for the walls has the advantages of high strength and toughness, high barrier and waterproofness, heat insulation, no toxicity, odorlessness, environment friendliness and less proneness to seasoning crack, thereby being used as a wall material preferably.

Description

technical field [0001] The invention relates to a foamed wall material and a preparation method thereof, in particular to an environmentally friendly high-strength, high-barrier, lightweight foamed material for walls Background technique [0002] At present, building energy conservation and environmental protection have been highly valued, and various energy-saving methods and energy-saving materials are widely used. As wall materials, the requirements for heat preservation and barrier properties are getting higher and higher. Walls prepared simply by using cement foam blocks The material is still bulky and heavy, and it is prone to foaming defects, which will lead to foam breaking. How to realize the light weight, barrier and maintain excellent mechanical properties, fire prevention and frost resistance of the wall through the combination of materials on the basis of traditional cement performance, it will have significant application prospects. The invention adopts compou...
