At present, the traditional aggregates are expanded perlite and polystyrene particle insulation mortar, but these two aggregates have inherent defects: expanded perlite has a porous structure, and when it is stirred in masonry mortar and plastering materials, moisture will be carried The cementitious material penetrates into the pore structure, fills its cavities, and loses its insulating effect after drying
Polystyrene particles in polystyrene particle insulation mortar are flammable materials, polystyrene particle insulation mortar has poor fire resistance, and it is easy to produce harmful gases at high temperatures

Abstract
The invention provides inorganic active thermal-insulation mortar. The inorganic active thermal-insulation mortar is prepared from the following raw materials in parts by weight: 100 to 140 parts of cement, 110 to 150 parts of inorganic lightweight aggregate, 15 to 25 parts of ash calcium powder, 15 to 25 parts of fly ash, 50 to 70 parts of active magnesium oxide powder, 18 to 28 parts of silica powder, 20 to 40 parts of nano clay, 0.3 to 0.5 part of anti-crack fibers, 1 to 1.5 parts of a thickening agent, 0.5 to 1 part of a water repellent and 0.05 to 0.1 part of an air entraining agent. The inorganic active thermal-insulation mortar provided by the invention has the characteristics of environmental protection, no toxicity, aging resistance, pressure resistance, impermeability and high strength, is safe and reliable, realizes A-level fire prevention, presents good heat insulation performance and has a heat conductivity coefficient as low as 0.059; the waterproof and anti-cracking performance of the motor is excellent, a waterproof film is formed on the surface of the produced motor after the motor is naturally dried, and the waterproof and anti-cracking performance is achieved; and the anti-freezing and anti-thawing performance of the motor is excellent, and construction can be performed at a temperature of -15 DEG C.
Description
technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an inorganic active thermal insulation mortar. Background technique [0002] Inorganic thermal insulation mortar is a new type of thermal insulation and energy-saving mortar material used for painting the interior and exterior walls of buildings. The traditional inorganic thermal insulation mortar is prepared by mixing expanded perlite, cement or building gypsum, and a small amount of additives in a certain proportion. Its performance changes with the ratio of expanded perlite to cementitious materials. It is an early thermal insulation mortar widely used. At present, the traditional aggregates are expanded perlite and polystyrene particle insulation mortar, but these two aggregates have inherent defects: expanded perlite has a porous structure, and when it is stirred in masonry mortar and plastering materials, moisture will be carried The cementitious mat...
