Problems solved by technology

[0002] House exterior wall insulation is one of the important contents of environmental protection. At present, polystyrene and polyurethane insulation boards are used. These insulation materials have played an excellent role in exterior wall insulation, but there are also serious safety hazards. Mainly, fire accidents are prone to occur in the construction of external wall insulation. In recent years, fire accidents of insulation materials caused by external wall insulation construction have caused heavy losses to people's lives and property. Therefore, it is an important content to prevent flame-retardant packaging of insulation materials.
