Description
Technical Field
The invention relates to the technical field of exterior wall coatings, in particular to a double-component exterior wall thin heat insulation material and a using method thereof.
Background
The building outer wall is used as the outermost layer structure of a building and is mainly formed by curing concrete mortar, and under long-term rainwater intrusion, the outer wall material is easy to crack and discolor due to aging, so that water seepage or acid gas invasion is caused, and the concrete mortar is accelerated to age. The heat-insulating bricks embedded on the outer wall are also mainly porous foam cement or heat-insulating materials such as heat-insulating cotton, asbestos, polyurethane foam and the like wrapped in a cement shell. Once cracks appear on the surface of the insulating brick, water seepage or harmful acid gas invasion can be caused, and the corrosion speed of foam cement or an insulating material inside the insulating brick is accelerated. At present, the coating used by common external walls mainly plays a role in repairing cracks, preventing water and corrosion, does not consider the functions of heat insulation and heat preservation, and the building energy consumption caused by heat exchange inside and outside the building is an important component of the current energy consumption. In addition, the exterior wall coating is directly contacted with wind, sunlight and rain all the year round, so that a coating film is easy to weather and peel, and finally falls off in a sheet manner, and the effect of the exterior wall coating cannot be maintained for a long time. For example, coatings made of acrylic emulsion, fluorocarbon clear paint and the like which are commonly used at present are easy to delaminate and crack when being used outdoors.
