Description

technical field [0001] The invention belongs to the field of energy-saving and environment-friendly materials, and in particular relates to a high-permeability rare earth nano heat insulation slurry and a preparation method thereof. Background technique [0002] In recent years, more and more attention has been paid to the issue of energy shortage, and energy conservation and emission reduction have become the main theme of the times. According to statistics, nearly 1 / 3 of global greenhouse gas emissions are related to building energy consumption. For occasions where a large amount of glass is used, such as building windows, ceilings, and car windows, the thermal radiation of light will lead to a substantial increase in energy consumption. The current solutions mainly include thermal insulation coatings and glass film with inorganic functional materials such as ITO (Indium Tin Oxide) and ATO (Antimony Tin Oxide) as additives. Contradictions between light rates. There are ...
