Thermal insulation mortar for building

Abstract

The invention discloses a building thermal insulation mortar, which is made of the following raw materials in parts by weight: 70-90 parts of cement, 8-12 parts of lime powder, 3-5 parts of expanded perlite, 4-7 parts of sodium bicarbonate, silicic acid 3-5 parts of sodium, 4-6 parts of glass fiber, 1-3 parts of hydroxymethyl cellulose, 1-2 parts of copper sulfate heptahydrate, 4-7 parts of aluminum oxide, 2-4 parts of polyethylene oxide. The composition of the thermal insulation mortar of the present invention is simple, scientific and reasonable, has excellent thermal insulation performance, bonding strength, compressive strength, weather resistance, waterproof and mildew proof, crack resistance, impact resistance and other properties, and can significantly improve the quality of building construction .

Description

technical field [0001] The invention relates to the field of building materials, in particular to a building thermal insulation mortar. Background technique [0002] Insulation mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed with water by the production enterprise. It can be used not only for external thermal insulation of building exterior walls, but also for internal thermal insulation of external walls, or both internal and external thermal insulation of external walls, as well as thermal insulation of roofs and geothermal heat insulation layers, providing certain flexibility for the design of energy-saving systems. It has the advantages of convenient construction, good durability, light weight, heat preservation and heat insulation. In recent years, there have been many researches on thermal insulation mortar in my country, and there have been many application...
