preparation example Construction

[0114] The coating preparation method of the selective radiation refrigeration coating of the present invention may include brush coating, roller coating and spray coating. The coating preparation process may include: preparing raw materials such as resin, granular fillers, additives and / or solvents, first pre-dispersing at high speed, then grinding and dispersing, then stirring evenly, then filtering and testing, and then packaging to prepare the layers of the coating. The primer resin layer, the first radiant cooling functional layer, the second radiative cooling functional layer, and the weather-resistant resin layer of the paint can be coated on the surface of the substrate in sequence by brushing, roller coating, and spraying, and one layer can be used. Apply the next coat after drying.

[0115] The selective radiation refrigeration coating of the present invention has a reflectivity of solar spectrum energy greater than or equal to 80%, an atmospheric window emissivity o...

Abstract

The invention discloses a selective radiation refrigeration coating and a composite material and application method thereof. The selective radiation refrigeration coating comprises a radiation refrigeration function layer with special structure particle filler. The radiation refrigeration function layer is used for reflecting ultraviolet light and / or visible light and / or near infrared light in sunlight and emitting heat through an atmosphere window in an infrared radiation mode, the radiation refrigeration function layer comprises a rodlike structure particle filler and radiation refrigerationfunction layer resin, and the particle filler is distributed in the radiation refrigeration function layer resin. According to the coating, the reflectivity for solar spectrum energy is larger than or equal to 80%, the reflectivity of the atmosphere window is larger than or equal to 80%, and the radiation refrigeration power being 100 W / m<2> or above can be supplied under the normal temperature.The coating is high in mechanical strength and good in weather resistance and has the quite high practical value.

Description

technical field [0001] The invention relates to the technical field of material science, in particular to a selective reflection and emission radiation cooling paint, composite material and application method thereof. Background technique [0002] The sun is a huge source of radiation. When the sun shines on the earth, part of the energy is absorbed by the atmosphere and part is reflected back to the universe. Due to the heat absorbed by the earth's surface, the surface temperature of objects on the earth is much higher than the temperature of the air above the surface. Cooling objects increases energy consumption and creates more greenhouse gas emissions. In the radiant energy spectrum of sunlight per minute, the energy occupied by the ultraviolet, visible, and near-infrared parts is 6.6%, 44.7%, and 48.7%, respectively, such as figure 1 shown. [0003] Radiation cooling is to use space as a cold source and objects on the ground as a heat source to establish a radiative h...
