Problems solved by technology

In addition, due to direct exposure to wind, sun, and rain all year round, the exterior wall paint is prone to weathering, peeling, and eventually flakes off, which cannot maintain its effect for a long time
For example, paints made of acrylic emulsions and fluorocarbon transparent paints that are commonly used at present are prone to delamination and cracking when used outdoors.

Description

technical field [0001] The invention relates to the technical field of exterior wall coatings, in particular to a multifunctional thin-body thermal insulation material for exterior walls of buildings and a preparation method thereof. Background technique [0002] As the outermost structure of the building, the exterior wall of the building is mainly formed by solidification of concrete mortar. Under long-term rainwater intrusion, the exterior wall material is prone to cracks and discoloration due to aging, resulting in water seepage or harmful acid gas intrusion, making the concrete mortar Accelerated aging. The insulation bricks inlaid on the outer wall are mainly some porous foam cement or insulation cotton, asbestos, polyurethane foam and other insulation materials wrapped in the cement shell. Once cracks appear on the surface of the insulation brick, it will cause water seepage or intrusion of harmful acid gas, which will accelerate the corrosion rate of foam cement or ...
