Problems solved by technology

The materials currently used for external wall insulation have a huge potential fire hazard from the perspective of fire protection. These materials themselves have poor fire and flame retardancy, and they spread very quickly after burning, which can easily cause the expansion of the fire. In addition, the current external Insulation materials for walls are applied on the periphery of buildings, which have poor oil resistance and anti-fouling properties and are not easy to clean

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an antifouling and environment-friendly thermal insulation and flame-retardant material for external walls. Background technique [0002] External wall insulation is a building insulation and energy-saving technology that is vigorously promoted at present. External wall insulation can protect the main structure, prolong the life of the building, effectively reduce the thermal energy of the building structure, and not affect the original effective space of the building. At present, the materials used for external wall insulation have a huge potential fire hazard from the perspective of fire protection. These materials have poor fire resistance and flame retardancy, and they spread very quickly after burning, which can easily cause the expansion of the fire. In addition, the current exterior Insulation materials for walls are applied on the periphery of buildings, have p...
