The invention provides a thermal insulation coating. In parts by weight, the thermal insulation coating comprises the following raw materials: 5 to 30 parts of a base material, 1 to 6 parts of an alkali activator, and 0.5 to 5 parts of an alkali activator. parts of thermal insulation material, 4 to 12 parts of water, and 0.02 to 4 parts of auxiliary; wherein, the base material comprises aluminosilicate; and the thermal insulation material is aerogel. The thermal insulation coating has strong thermal insulation, compressive strength and high temperature resistance. Further, the thermal insulation coating of the present invention is economical and environmentally friendly, requires a simple preparation process, and is suitable for industrialized large-scale production. |
