Especially for their excellent heat preservation performance, it has been fully utilized in the aspect of integrated heat preservation. However, with the improvement of heat preservation requirements, its disadvantages have gradually emerged. With the improvement of national standards, the sound insulation index of the original thickness of autoclaved aerated concrete exterior wallboards fails to meet the design requirements; the production of hollow boards generally uses inorganic porous heat preservation materials (such as rock wool) or organic hot melt substances (polyurethane) arranged in the middle of the wire cage, and then pouring and autoclave curing are carried out. After forming a hollow layer, heat preservation materials such as polyurethane are poured again. Polyurethane materials have high costs, are unstable at high temperatures, and release toxic gases when burned. Phenolic heat preservation boards are new substances formed by the reaction of phenolic and aldehyde resins; this material has stable physical properties, does not release toxic substances when heated or burned, has a small thermal conductivity of phenolic heat preservation boards, and has good heat preservation effects, and is an ideal heat preservation material. However, due to the fact that phenolics are easy to absorb water and are prone to powdering under ultraviolet irradiation, in an environment of high-temperature steam, the volume expands after absorbing water, causing the wallboard to burst during the process of being compounded with the heat preservation board.

[0003] Therefore, how to provide a composite heat preservation wallboard made of a hot melt board that uses phenolic heat preservation boards and autoclaved aerated concrete to be integrally compounded, will not cause damage to the wallboard, and can utilize the heat preservation of the air insulation layer is one of the technical problems that need to be urgently solved in this field.
