Abstract

The invention discloses composite thermal insulation mortar which solves the problem that the thermal insulation property of existing thermal insulation mortar is not good and achieves recycling of crop straws. The composite thermal insulation mortar is composed of, by weight, 70-80 parts of cement, 10-15 parts of coal ash, 5-20 parts of calcium hydroxide, 10-20 parts of rice straw fibers, 30-40 parts of glass beads, 0.5-0.8 part of cellulose ether, 0.1-0.2 part of starch ether, 0.01-0.05 part of air entraining agents, 1-4 parts of emulsion powder and 150-190 parts of water, wherein the cement, the coal ash and the calcium hydroxide account for 100 parts. According to the composite thermal insulation mortar, the crop straws are fully utilized and recycled; meanwhile, the rice straw fibers of agricultural waste and the coal ash of industrial waste can be utilized, and the composite thermal insulation mortar is environmentally friendly, low in energy consumption and capable of being widely applied to thermal insulation of internal walls and external walls of buildings.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a composite thermal insulation mortar and a preparation method thereof. Background technique [0002] In my country's current social and economic structure, building energy consumption has reached 27.6% of the total energy consumption of the whole society. With the improvement of people's living standards, heating and cooling energy consumption continues to increase, and building energy consumption accounts for 27.6% of the total energy consumption. The proportion will continue to increase, and the contribution of building energy conservation to energy conservation is of great significance. The focus of building energy conservation in my country is: energy saving of building envelope, energy saving of building heating system, improvement of efficiency of lamps and other electrical appliances, energy saving of newly built large public buildings, and energy sa...
