Problems solved by technology

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 is easy to cause the expansion of the fire; Adhesive performance is not very good and seriously affects the effect of external wall insulation; in addition, after long-term use, the thermal insulation materials of the prior art are easy to age, deform and fall off after being washed by rainwater, and the thermal insulation effect will be greatly reduced

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an erosion-resistant, heat-preserving and flame-retardant material for exterior 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 is easy to cause the expansion of the fire; Adhesive performance is not very good and seriously affects the effect of external wall insulation; in addition, after long-term use, t...
