Cesium tungsten bronze nanopowder is the best dingal material for preparing transparent heat insulating coating as it has better near-infrared absorption characteristics than common thermal insulation materials such as ATO and ITO. In addition, such coating also has the characteristics of excellent UV shielding effect and environmental protection. Well, do you know how to prepare such a transparent heat insulating coating using cesium tungsten bronze nanopowder as a raw material?

According to the experts, the cesium tungsten bronze heat-shielding coating can be prepared by the following steps: Add cesium tungsten bronze nanoparticles, deionized water, dispersant, sodium hydroxide or nitric acid to an agitator. After being stirred uniformly, it is pumped into a sand mill for grinding and dispersion until the particle size of the slurry does not decrease basically, and then stop sand grinding to obtain cesium tungsten bronze nano slurry. The cesium tungsten bronze nano slurry was added to the acrylic emulsion, and the film was coated on a glass substrate and then dried to obtain a dry film with thickness of about 5 μm. Among them, the coating addition amount of the cesium tungsten bronze nano sully was 1.3 g/m2.
