Abstract

The invention discloses light compound thermal-insulation mortar. The light compound thermal-insulation mortar comprises the following components in parts by weight: 35-40 parts of cement, 8-12 parts of converter slag granules, 12-18 parts of a reinforced material, 16-22 parts of compound thermal-insulation aggregate, 0.25-0.35 part of resin type redispersible powder, 0.6-0.9 part of cold water type polyvinyl alcohol, 0.1-0.2 part of hydroxypropyl methyl cellulose, 0.01-0.03 part of air entraining agent, 0.06-0.1 part of water glass, 0.005-0.01 part of inorganic retarder, 8-13 parts of polyphenyl granules, 30-50 parts of glass beads and 0.2-0.5 part of concrete water-proofing agent. The light compound thermal-insulation mortar has the advantages that the cement is saved; meanwhile, the thermal-insulation aggregate is added, so that the mortar has a light effect; meanwhile, an thermal-insulation effect is enhanced; after the construction is finished, the mortar is unlikely to crack and fall and can effectively resist water and fire.

Description

technical field [0001] The invention relates to a building material, in particular to a lightweight composite thermal insulation mortar. Background technique [0002] At present, domestic and foreign building wall insulation generally adopts plate or component thermal insulation materials, which are expensive, difficult in construction technology, and poor in impact resistance, but have good thermal insulation effects and are suitable for cold regions; there is another thermal insulation material, namely Rubber powder polystyrene particle external wall thermal insulation system, the thermal insulation system is composed of interface layer, thermal insulation layer, anti-crack protective layer, which plays the role of thermal insulation and protection. In the prior art, there is cement in each layer of the rubber powder polystyrene particle external wall insulation system, but because the cement is a hydraulic material and forms cement stone with hydrate, it usually takes 28 ...
