Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a building thermal insulation coating. Background technique [0002] Thermal insulation coating is a functional coating developed in recent years that reflects heat and light, has short construction period and quick effect. There are three main types of thermal insulation coatings in terms of characteristics and principles: insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings. [0003] The mechanism of action of radiation-type heat-insulating coatings is to emit sunlight and heat absorbed by buildings into the air at a certain wavelength in the form of radiation, which blocks the transfer of heat energy and reduces the heat gain of buildings, thereby achieving good heat insulation. Energy saving effect. Radiation cooling coating is a coating that radiates heat and insulates heat. The rad...
