Hydrophobic expansive perlite waterproof heat insulation mortar and preparation method thereof
The invention relates to hydrophobic expansive perlite waterproof heat insulation mortar and a preparation method thereof, and belongs to the technology for improving the waterproof performance of traditional expansive perlite heat insulation mortar. The heat insulation mortar is prepared from, by mass, 100-140 parts of ordinary portland cement, 50-70 parts of sulphoaluminate cement, 60-80 parts of fly ash, 20-40 parts of silica fume, 150-200 parts of expanded perlite (organic silicon water repellent modification), 30-42 parts of an expanding agent, 15-27 parts of a capillary crystalline master batch, 3-9 parts of dispersible emulsion powder, 0.3-0.6 part of an air entraining agent, 0.6-1.2 parts of cellulose, 2-5 parts of a water reducing agent, 15-21 parts of a special waterproof agent for perlite and 280-340 parts of water. Compared with ordinary expansive perlite heat insulation mortar, the hydrophobic expansive perlite waterproof heat insulation mortar has the low water absorption rate and heat conductivity coefficient and the high strength, has the micro-expansion performance and other characteristics, is good in building wall caking property, free of empty drums and cracking and good in water resistance and fire resistance and has the same service life cycle as a building.
