Technical Field

The invention relates to the technical field of building materials, in particular to an aerogel cement fiber composite insulation board.

Background

Buildings are one of the largest energy consumption in the world, and the consumed energy and the released greenhouse gas amount account for one fourth to one third of the total energy consumption in the world. In recent years, due to factors such as rising energy price, sudden increase of power demand, and increasing concern for environment, people pay close attention to energy conservation of buildings. The cement-based composite material can be used as a heat-insulating layer material or a fireproof isolation strip of an external heat-insulating system of an external wall, and can also be used as a building roof heat-insulating material, a composite wall core layer material, a composite heat-insulating block filling material and the like. The material has the advantages of mature production process, easily-controlled quality, excellent performance and convenient use, is an ideal low-cost heat insulation material, and has the obvious defects of low strength, high heat conductivity, easy moisture absorption and the like. Therefore, the modification of the defects is particularly important, and in addition, along with the improvement of the living requirements of people, the demand of novel heat-insulating materials integrating multiple functions of fire prevention, antibiosis, water prevention, sound absorption and the like is increasingly obvious; the aerogel cement fiber composite insulation board is researched to meet the requirement.
