Problems solved by technology

[0002] At present, it is a traditional polystyrene thermal insulation material widely used in building wall thermal insulation projects, which has the following disadvantages: The disadvantages of the expanded polystyrene board thin plaster external wall thermal insulation system are: poor fire resistance and water seepage resistance, The process is complicated and the project cost is high (the cost of materials per square meter is 70-80 yuan); the wind pressure and impact resistance and the firmness of the insulation layer are poor, and the service life is short. Large areas of cracks, hollowing, falling off, etc., or because the rivets are not firmly riveted or the rivets are rusted, the foam board and extruded board slowly degrade and the surface layer cannot use oily solvent-based paint, etc. Once the above problems occur, repair or The cost of rework is quite high
The disadvantages of the polystyrene particle thermal insulation slurry thermal insulation system are: firstly, the fire prevention and impermeability are poor, and it is prone to cracks, hollows, and shedding; secondly, there is an irreconcilable contradiction between the thermal insulation effect of the system and the strength of the thermal insulation layer: To improve the thermal insulation effect, it is necessary to increase the content of polyphenylene particles in the slurry and reduce the content of cement mortar, resulting in insufficient strength of the insulation layer; if the strength of the insulation layer is emphasized, it is necessary to increase the content of cement mortar in the slurry and reduce the content of polyphenylene particles, resulting in insufficient insulation strength. Reduced effect
