Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a coating for thermal insulation of architectural glass containing an aqueous slurry of inorganic thermal insulation nanomaterials and a preparation method thereof. Background technique [0002] Since the 20th century, the world's energy consumption has increased significantly. Energy saving and consumption reduction and economic benefit improvement are one of the basic goals of scientific research and technological development. It is of great significance to develop thermal insulation and environmental protection materials. Transparent heat-insulating coating materials can fully solve the heat insulation problem of building doors and windows, not only save energy, but also create a comfortable indoor environment for people that is warm in winter and cool in summer. [0003] my country's research on transparent heat-insulating coating materials started relatively late, and the Chi...
