[0002] In the field of construction, the application of thermal insulation materials plays a key role in reducing building energy consumption. However, there are often some problems in the use of traditional thermal insulation materials. On the one hand, many thermal insulation materials have poor fireproof performance. In recent years, fire accidents caused by building thermal insulation materials have occurred from time to time, posing a great threat to people's life and property safety. On the other hand, the combination of thermal insulation materials and building main structure is not ideal, which is easy to cause hollowing, falling off and other phenomena, affecting the thermal insulation effect and the service life of the building.
