Abstract

The invention discloses inorganic composite thermal mortar, which comprises ordinary Portland cement, coal ash, glass beads, expanded perlite, polypropylene fibers, heavy calcium powder, ash calcium powder, mineral fibers and a composite additive. By adopting the invention, fireproof insulation layers are constructed on the wall space and the top surface of the building effectively, the heat insulation property of the building is greatly improved, energy consumption for heating in winter and cooling in summer is reduced, and the inorganic composite thermal mortar has the advantages of light density, small heat conductivity coefficient, high temperature resistance, fire resistance, safety use, environmental friendliness and durability. The inorganic composite thermal mortar is suitable for thermal insulation construction of wall spaces and roofs, such as reinforced concrete, concrete, aerated concrete blocks, clay bricks, steel structures and the like, and is also suitable for construction of fireproof insulation layers, such as underground garage, elevator wells, tube wells, cold storages and the like.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an inorganic composite thermal insulation mortar. Background technique [0002] Building energy saving is a hot issue at this stage in our country. Building fire prevention and flame retardant are the most important aspects to ensure the safety of people's lives. Many types of thermal insulation materials have emerged on the market. [0003] Organic insulation materials mainly include polyurethane, polystyrene foam, polymerized phenolic resin foam and rubber-plastic foam. This type of material is widely used due to its unique low thermal conductivity, light weight, and strong hydrophobicity. However, due to the flammability of organic materials, especially the high smoke coefficient, high toxicity, and significant (direct and potential) serious pollution to the environment, their applications are limited. [0004] Compared with organic thermal insulation materials,...
