The current building thermal insulation materials are widely applied to low-energy buildings, and mainly different static thermal insulation materials are arranged on the outer surface, the inner surface or the middle position of a wall body of the building. For buildings using static heat-insulating materials, the thickness of the heat-insulating layer is required to be increased continuously to reduce the comprehensive heat transfer coefficient value of the enclosure structure in order to reduce the energy consumption of the building. However, the use of static insulation materials in large quantities in construction creates a number of problems. Firstly, a large amount of valuable use space in a building is occupied by an excessively thick heat preservation layer, secondly, the problem of fire hazard of a static heat preservation material cannot be effectively solved all the time, and a large amount of fire risks can be generated by application, thirdly, the static heat preservation material is an industrial product with high hidden carbon emission, and is largely used against a carbon neutralization target in the field of the building, and in addition, the thermal resistance value of the static heat preservation layer cannot be changed in the use process, so that the use of cold energy at night in a transition season and a refrigeration season is not facilitated, and the problem that the energy consumption of the building is increased instead is possibly caused by excessive use of the heat preservation layer.
