Abstract

The invention relates to an EIA (Environmental Impact Assessment) ecological environment-friendly type inorganic active building heat-insulating mortar which comprises polymer rubber powder, cellulose ethers, wood fibers, air entraining agents, efficient moisture repellents, thixotropic agents, ordinary portland cement, calcium powder, coal ash, light aggregates with low coefficient of heat transfer, such as high-hydrophobicity expanded perlite or vitrified micro-beads, polypropylene fibers and excellent mineral powder with low heat conductivity. The defects of the traditional heat-insulating material of low fireproof performance, easiness in generating harmful gas at high temperature, low weather resistance, hollowing resistance, cracking resistance, air pressure resistance and impact resistance are overcome by the mortar provided by the invention. The mortar is suitable for the inner and outer heat-insulating plastering projects for retaining walls, such as reinforced concrete, aerated concrete, built blocks, baked bricks and non-baked bricks, of multilayer and high-rise buildings, is suitable for the fireproof heat-insulating projects, such as basement, garage, stair, corridor and fire engine access, and is also suitable for the heat-insulating modifying projects of various old buildings. During a construction process, the process is more convenient than the process of the traditional heat-insulating system, and the uncertain hidden danger caused by the mixing use of different materials is avoided.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a "building insulation mortar". Background technique [0002] The thermal insulation mortar currently used in construction projects mainly includes expanded perlite thermal insulation mortar, fly ash thermal insulation mortar and EPS thermal insulation mortar. Expanded perlite thermal insulation mortar has a high water absorption rate and poor crack resistance, so it can only be used as internal thermal insulation. Its application has great limitations, and its thermal performance needs to be further improved. Fly ash insulation mortar is still in the development and trial period. EPS thermal insulation mortar has poor fire resistance, low strength, easy to produce harmful gas at high temperature, and poor aging resistance and weather resistance. At present, the existing "building insulation mortar" in my country is suitable for the thermal insulation lay...
