It is an important national policy that contributes to energy conservation, emission reduction and environmental protection. Thermal insulation and heat insulation treatment of building walls is one of the important measures to implement building energy conservation. In order to meet the requirement of 65% building energy saving, building wall insulation materials play an increasingly important role in building energy saving, and the country's requirements for building fire performance are also getting higher and higher. At present, building wall insulation materials are mainly divided into organic materials and inorganic materials. Organic insulation materials mainly include molded polystyrene foam board (EPS), extruded polystyrene foam board (XPS), rigid polyurethane foam board (PU) ), phenolic foam insulation board (PF), rubber powder polystyrene particle insulation board, etc. Inorganic insulation materials mainly include foam concrete board, foam cement board, foam ceramic board, foam glass board, rock wool board, mineral wool board, Glass wool insulation board, vitrified bead insulation board, etc., all of the above insulation materials have certain defects, such as XPS, PU and other organic materials have disadvantages such as poor fire resistance and high toxicity of combustion products, PF board has excellent fire resistance Performance, the oxygen index can reach more than 50%, but it has the disadvantages of brittle surface, easy pulverization, slag falling, and low bonding strength. Inorganic insulation materials are non-combustible materials with excellent fire resistance, but their insulation performance generally cannot meet Building energy saving requirements of 65%. The various shortcomings of the above-mentioned building wall insulation materials limit their wide application to a certain extent.
