Abstract

The invention discloses a radiation refrigeration paint and applications thereof. The radiation refrigeration paint comprises polymer emulsion, a self-repairing agent, and radiation refrigeration particles, wherein the self-repairing agent and radiation refrigeration particles are dispersed in the polymer emulsion. The self-repairing agent comprises a wall layer and a self-repairing core material, which is wrapped by the wall layer. When the wall layer is broken down, the self-repairing core material is released. The self-repairing core material is used to realize self-repairing of a coating. For the first time, a self-repairing material is introduced into a radiation refrigeration paint so as to obtain a coating with a self-repairing function, when a coating is scratched or damaged, self-repairing can be performed quickly, the service life of the coating is prolonged, and thus the stability of the radiation refrigeration effect of the coating is guaranteed.

Description

technical field [0001] The invention relates to the technical field of radiation refrigeration, in particular to a radiation refrigeration coating and its application. Background technique [0002] Radiation cooling refers to the cooling method that releases heat directly from the atmospheric window to outer space through infrared radiation. The characteristic of radiation cooling is that the surface temperature of the cooling body is always lower than the air temperature, and then the temperature of the radiation cooling body is lowered below the air temperature through conduction, so as to achieve the purpose of radiation cooling. [0003] Publication No. CN108250873A discloses a kind of outdoor all-weather sunlight reflection and infrared radiation refrigeration coating, by adding micron-scale spherical microbeads, micron-scale metal-coated flakes, and / or micron-scale metal-coated spherical bodies In the coating system, the method of layered coating is adopted, and the c...
