Abstract

The invention discloses an infrared radiation insulating coating and paint and a preparation method thereof. The infrared heating coating is mainly prepared from the following components in parts by weight: 1 part of spherical graphene, 0.02 to 0.12 part of graphitizable macromolecular oligomer, 1 to 4 parts of polyaluminosilicate, 0.5 to 2 parts of hyperbranched carbosilane and 0.01 to 0.1 part of peroxide cross-linking agent. According to the infrared heating coating, by means of the corrugated structure of spherical graphene, under the cohesion and combination effect of macromolecules, theinsulation effect of an insulation aluminum-silicon compound and the cooperation of small-molecule high-radiation inorganic particles, the multi-stage infrared heating is achieved. By means of the infrared heating coating, the heating efficiency is greatly improved; meanwhile, in the field of infrared radiation heating, the comfort of a human body is improved, and the energy consumption is greatlyreduced.

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] The existing infrared radiation heating coating, in order to achieve insulation performance, is 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 c...
