Abstract

The invention relates to waterproof crack-resistant inorganic heat-insulating mortar and a preparation method thereof. The mortar comprises 5-10 m<3> of small expended and vitrified balls, 0-1 m<3> of pottery sand, 750-850 kg of ordinary portland cement, 50-100 kg of calcium powder, 35-70 kg of hydrated lime, 30-55 kg of siliceous dust, 15-20 kg of dispersible polymer powder, 4-8 kg of hydroxypropyl methyl cellulose ether, 1-2 kg of mekralon, 0.5-1 kg of capillary crystalline waterfroof agent, and 3-5 kg of wood fiber. The preparation method comprises the following steps: loading ordinary portland cement, siliceous dust, hydrated lime, hydroxypropyl methyl cellulose ether, dispersible polymer powder, calcium powder, mekralon, capillary crystalline waterfroof agent and wood fiber at one time, and stirring for 3 min; adding small expended and vitrified balls and pottery sand in the stirred powder blend, and continuously stirring for 2 min; and packaging and storing the finished productsin warehouse. Compared with the prior art, by using the pottery sand and capillary crystalline waterfroof agent, the problems of large water absorption, easy cracking when water seepage occurs and the like of traditional inorganic small expended and vitrified ball heat-insulating mortar are solved.

Description

technical field

[0001] The invention relates to a waterproof and crack-resistant inorganic thermal insulation mortar. The material can be used for thermal insulation of external walls, and is particularly suitable for internal thermal insulation of external walls, internal walls and household walls, and belongs to the field of thermal insulation of buildings. Background technique

[0002] Due to the upgrading of fireproof performance requirements of building insulation materials, inorganic insulation materials have become the mainstream materials of insulation materials. Among them, inorganic thermal insulation mortar has a Class A combustion grade and has become one of the main products of building energy-saving materials in hot summer and warm winter regions. After searching the literature of the prior art, it was found that the patent number is CN101863639, and the patent name is an invention patent for an inorganic thermal insulation mortar used for building exterior wal...
