[0002] Existing thermal insulation materials include polystyrene thermal insulation mortar, inorganic thermal insulation mortar and foamed plastics. Polystyrene thermal insulation mortar and inorganic thermal insulation mortar have the disadvantages of water absorption and swelling, and the strength is inversely proportional to thermal insulation performance. The construction is complicated and the service life is short. Foam plastics have poor fire resistance, low strength, poor air permeability, complex construction, and short service life; the above-mentioned insulation materials are prone to cracking and water seepage, which affects the use of disadvantages. In order to meet the needs of the current social energy-saving building development and overcome the above-mentioned insulation materials However, the foam concrete insulation material has the advantages of low cost, good crack resistance, and low thermal conductivity. However, most of the existing foam concrete insulation materials contain polypropylene organic fibers or glass fibers. In order to increase the strength, but the organic fiber has poor heat resistance, is easy to age or carbonize, and is easy to cause cracks in the product, and the glass fiber has a large proportion, which aggravates and affects the thermal insulation performance of the product. The existing sulphoaluminate foam insulation board adopts improved Surface impregnation polymerization of non-toxic acrylic polymer to form a hydrophobic film treatment, the hydrophobic film affects the air permeability and reduces the thermal insulation performance, and the acrylic hydrophobic film is easy to age or carbonize, and the hydrophobic film has a short stabilization time, which can only meet the early stage of use. The requirement of low water absorption is a temporary solution, not a permanent solution, which will affect the long-term stability of the thermal insulation effect

[0003] The insulation layer of the existing thermal insulation and decoration integrated board is mostly organic foam plastics, its water vapor transmission rate is low, the indoor moisture cannot be discharged, and the moisture condenses on the outer surface of the wall, which is easy to produce condensation reaction and freeze-thaw cycle, which will damage the main body of the building. The structure causes damage and directly affects the stability and service life of the thermal insulation system. Although the thermal insulation and decoration integrated board meets the thermal insulation requirements, its cost is high, the construction cost is large, the construction period is long, the service life of the thermal insulation system is short, and the air permeability is poor. Indoor air is turbid and unsuitable for human habitation, etc. The exterior finishes are mostly composed of calcium silicate boards, fiber cement boards, metal plates, and composite resin boards, and most of the exterior finishes are glued to the insulation layer. connection, the overall performance is not good, and its positioning connector is a good heat conduction body, which is easy to form a cold bridge
