Abstract

The invention discloses a composite thermal-insulation mortar for outer walls, which is prepared from the following components in percentage by weight: 60-80 parts of cement, 0.25-0.35 part of resin-type redispersible latex powder, 0.6-0.9 part of cold-water polyvinyl alcohol, 0.1-0.2 part of hydroxypropyl methylcellulose ether, 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 granule, 30-50 parts of vitrified microbead and 0.2-0.5 part of concrete waterproofing agent. The mortar has the advantages of favorable thermal-insulation effect and low tendency to bulging or shedding after construction, and can effectively resist water and fire.

Description

technical field [0001] The invention relates to a building material, in particular to an exterior wall 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 days to...
