Abstract
The invention discloses an energy-saving and environmental protection inorganic thermal insulation mortar special for buildings. The inorganic thermal insulation mortar is characterized by being prepared from the following raw materials by weight part: 5-7 of plant ash, 14-17 of fly ash, 4-5 of rice husk, 2.5-3 of construction waste brick slag, 25-28 of Portland cement, 2-3 of expanded graphite, 22-25 of vitrified microspheres, 0.4-0.7 of sodium hexametaphosphate, 0.1-0.2 of lecithin, 1-1.5 of calcium peroxide, and 8-10 of a synergist. According to the invention, fly ash, plant ash and the like are added for partial replacement of cement, and the mortar dry density can be reduced, and the thermal insulation can be enhanced. The added expanded graphite endows the mortar with good lubricity and fluidity, and the construction performance is improved. By adding the synergist made by a special technology, the mortar can be waterproof, moistureproof and mothproof. Containing crop straw as the base material, the mortar is energy saving and environmental protection, and simultaneously the cement dosage is reduced. The inorganic thermal insulation mortar provided by the invention uses waste resources, is energy saving and environmental protection, and has enormous market space and development prospects.
