Higher requirements are put forward for the performance of fireproof insulation panels in the construction market.

The thermal conductivity of the existing A-class fireproof insulation board is relatively high. If it is to meet the high energy-saving requirements of the Ministry of Housing and Urban-Rural Development, the thickness of the material must reach 15 cm, and the drawing strength of this type of board is relatively low (about 0.05MPa). , so that it will have hidden dangers in construction and exterior wall safety. If you choose to use the current organic thermal insulation material as the thermal insulation board, its thermal insulation effect is really good, and the thermal conductivity is about 0.225W/(m·K), which meets the energy-saving requirements, but the fire performance is too poor to meet the building assembly requirements.

At present, there are a small number of patented products on the market that combine A-level fireproof boards and inorganic insulation boards. However, due to the existence of two different systems of materials and the poor combination process, there are quality accidents caused by factors such as aging and inconsistent thermal shrinkage. , so promotion is blocked. Based on this, the present application proposes a composite insulation board with a new structure.
