Abstract

The invention discloses a high-radiation heat-insulated coating which comprises the following components in parts by weight: 25-37 parts of infrared reflection pigments, 12-20 parts of aluminum-coated hollow microspheres, 15-28 parts of aerogel, 30-55 parts of organic resin, 0.1-0.2 part of a wetter, 0.36-0.47 part of a dispersant, 0.3-0.9 part of a defoamer, 0.02-0.1 part of a preservative, 0.02-0.1 part of a mildew preventive, 0.52-1.12 parts of a thickener, 1.2-2.4 parts of a film-forming aid and 0.03-0.18 part of a pH value regulator. The coating is provided with a plurality of photo-thermal reflection layers and heat-insulated barriers, has a good heat-insulated effect capable of reaching more than 98%, and is excellent in mechanical performance, large in adhesive force, good in weather resistance, water resistance, stain resistance, scrub resistance and the like, safe, environment-friendly and wide in application range.

Description

technical field [0001] The invention relates to a heat-insulating paint, in particular to a high-radiation heat-insulating paint. Background technique [0002] Building energy conservation occupies a major position in the national energy conservation. At present, materials such as polystyrene and extruded plastics are used to insulate buildings through construction techniques such as mounting and wrapping. Although these materials can also play a role in heat insulation, However, these materials have the disadvantages of being easy to burn, polluting the environment, complex construction technology, and short service life. Therefore, the industry has begun to develop heat-reflective and heat-insulating coatings for the exterior of buildings, which can be applied to the surface of objects to reduce the increase in surface temperature caused by solar radiation and achieve the purpose of heat-reflecting, heat-insulating, and energy-saving.
