Problems solved by technology

[0002] At present, the materials used in domestic building exterior wall insulation are mainly Class B insulation materials, such as polystyrene, polyurethane, foam rubber and other organic materials. These organic materials have poor heat resistance and are easy to burn. When burning, they not only release a lot of heat, A large amount of toxic smoke is produced, and it can accelerate the spread of the fire; at the same time, the organic material will shrink during the fire, resulting in burning droplets, causing the tiles on the insulation layer to fall off, which is likely to cause secondary fires and secondary fires. Second damage, so the relevant part of the country expressly prohibits the use of organic thermal insulation materials for external wall insulation, especially in high-rise buildings and public buildings
Among the thermal insulation materials whose combustion performance reaches the A-level standard, inorganic materials represented by mineral wool and rock wool are mainly used. However, the existing domestic products have a large gap with the requirements of architectural applications in terms of water absorption, strength, and weather resistance. If it is directly used for building wall insulation, there will be problems such as water absorption, falling, softening, etc.
In addition, the cost of Class A thermal insulation materials is much higher than that of organic materials, and the construction process is complicated. The construction cost far exceeds the cost of Class B thermal insulation materials, and its thermal insulation performance is poor and energy consumption is high, which cannot meet the current needs of the country for energy conservation and emission reduction.
