Problems solved by technology

[0005] The main disadvantages of thermal insulation and energy-saving coatings currently on the market include the large particle size distribution of metal light absorbing agents, unstable coatings, mirror effect after roller coating, visible particles, and poor adhesion between coatings and glass substrates due to large particles
At the same time, because the coating does not contain organic light absorbing agents, the energy-saving effect in the near-infrared region is not obvious, and the overall energy-saving effect is low

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a heat-insulating coating, in particular to an organic dye-enhanced transparent heat-insulating coating; meanwhile, the invention also relates to a preparation method and application of an organic dye-enhanced transparent heat-insulating coating. Background technique [0002] Solar radiation through glass is one of the main sources of heat indoors and in cars. In order to achieve energy saving, people use various methods to change the anti-radiation performance of glass. Glass film and magnetron sputtering metal film can effectively block solar radiation, adjust indoor and vehicle temperature, improve environmental comfort, and reduce air-conditioning energy consumption. [0003] In recent years, it has been found that some metal oxides have good optical absorption, such as antimony tin oxide (ATO), indium tin oxide (ITO), lanthanum hexaboride (LaB6), tungsten oxide (WO3),...
