The promotion and application of energy-saving technologies have reached a global consensus, and many countries have successively introduced related policies. A large proportion of building energy consumption is lost through glass doors and windows. Similarly, in the hot summer, the sun’s exposure through the car glass is unbearable for drivers and passengers, accelerating the aging of the vehicle interior, and greatly increasing fuel consumption, increasing emissions, and damaging the environment. Therefore, it is necessary to find a glass heat-insulating agent that is both transparent and heat-insulating.
Cesium-doped Tungsten Oxide/Cesium Tungsten Bronze is an inorganic nanomaterial with good near-infrared absorption. It has uniform particles, good dispersibility, environmental friendliness, strong light transmission ability, good near-infrared shielding performance, and high transparency. Stand out from other traditional transparent insulation materials. It is a new type of functional material with strong absorption in the near-infrared region (wavelength 800-1200nm) and high transmittance in the visible light region (wavelength 380-780nm).

At the same time, as a new type of automotive glass heat insulation agent, nano cesium tungsten oxide has the best near-infrared absorption characteristics. Usually, adding 2 g per square meter of coating can achieve an infrared blocking rate of more than 90% at 950 nm and more than 70% at the same time. The visible light transmittance.
The heat-insulating agent has been widely recognized by many glass manufacturers. This heat-insulating agent is used in the production of coated heat-insulating glass, coated heat-insulating glass, and laminated heat-insulating glass, which can significantly improve the comfort of the human body and save energy. . Nano cesium tungsten oxide can be said to be a kind of transparent heat-insulating nano powder. What you need to know is that cesium tungsten bronze nano powder is not really “transparent”, but a dark blue powder. “Transparency” mainly refers to the heat insulation dispersion, heat insulation film and heat insulation paint prepared from cesium tungsten bronze all exhibiting high transparency. Experts said that among them, the production of thermal insulation coatings needs to use film-forming materials, such as acrylic resin. Acrylic resin has excellent color and luster, good light and weather resistance, resistance to ultraviolet radiation without decomposition or yellowing, gloss and color retention, and can maintain the original color for a long time. Acrylic resin is often used in combination with other resins as a film-forming substance for transparent thermal insulation coatings. Some experts use polyurethane acrylate water-based resin as the film-forming material and nano-cesium tungsten bronze as heat-insulating particles to prepare transparent heat-insulating coatings, and apply them to architectural glass. Studies have shown that the coating has a transmittance of about 75% in the visible light region.
