Description

technical field [0001] The invention relates to the technical field of thermal insulation coatings, in particular to a nano ceramic high temperature thermal insulation coating and a preparation method thereof. Background technique [0002] Traditional thermal insulation materials are mostly porous loose materials, such as rock wool, glass wool, perlite, polyurethane foam, light calcium carbonate, etc. These materials block the movement of heated molecules and play a role in thermal insulation. However, heat transfer, in addition to solid heat transfer, also has radiation heat transfer, and radiation heat transfer is not affected by the medium, and the interface does not play a role. The higher the temperature, the stronger the radiation. Therefore, it is not enough to only consider solid heat transfer in the insulation of high-temperature heat transfer pipelines. [0003] Traditional insulation materials have a high water absorption rate of more than 200%. A large amount o...
