Description

technical field

[0001] The invention relates to the field of coatings, in particular to a water-based reflective heat-insulating coating and a preparation method and application thereof. Background technique

[0002] Under the scorching sun in summer, the atmospheric temperature is generally above 30°C. When the outer surfaces of building materials such as cement, concrete, tiles, metal, insulation bricks, and glass are exposed to the sun for a long time, their temperature can reach 40-50°C. , and when the color steel plate, waterproof material, etc. are exposed to the sun for a long time, their temperature can even reach a scalding temperature of 60-70°C. The above-mentioned situation has adversely affected normal human habitation, material storage, and equipment safety.

[0003] It is known in the art that the application of reflective heat-insulating coatings on building surfaces can effectively reduce the temperature of the building's surface and interior, and can allev...
