Description

technical field [0001] The invention belongs to the technical field of new nanometer materials, and in particular relates to an infrared radiation insulating coating, a coating and a preparation method thereof. Background technique [0002] With the development of society, human beings are more and more dependent on energy, but with the gradual consumption of fossil energy, the cost of energy is getting higher and higher. Therefore, it is imminent to use energy more efficiently in human life and production activities. At the same time, people have higher and higher requirements for the quality of production and life. Under the same energy conditions, comfort has become the first choice. [0003] Existing infrared radiation heating coatings, in order to achieve insulation performance, are usually equipped with a polymer insulating layer. Due to the limitation of the material of the polymer insulating layer itself, on the one hand, it has poor thermal conductivity (thermal con...
