The promotion and application of energy-saving technologies has reached a consensus in the world, and many countries have successively issued policies. In building energy consumption, a large proportion is lost through glass doors and windows. Similarly, in the hot summer, the exposure of sunlight through the car glass is unbearable for drivers and passengers, which accelerates the aging of the vehicle interior, and greatly increases fuel consumption, increases emissions, and damages the environment. Therefore, there is a need to find glass insulators that are both transparent and thermally insulating.

Cesium tungsten oxide/cesium tungsten bronze are inorganic nanomaterials with good absorption effect on near-infrared and ultraviolet, with uniform particles, good dispersibility, environmental friendliness, strong selective light transmittance, good near-infrared shielding performance, and high transparency. , which stands out from other traditional transparent insulation materials. It is a new functional material with strong absorption function in the near-infrared region (wavelength 800-1200nm) and high transmittance in the visible light region (wavelength 380-780nm).


Chinese name: Cesium tungsten oxide/cesium tungsten bronze
English name: Cesium Tungsten Bronze
CAS number: 189619-69-0
Molecular formula: Cs0.33WO3

Appearance: dark blue powder

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 more than 90% infrared blocking rate at 950 nm, and at the same time achieve more than 70% visible light transmittance.

The thermal insulation agent has been widely recognized by many glass manufacturers. It is used in the production of coated thermal insulation glass, coated thermal insulation glass, and laminated thermal insulation 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 insulation nano powder. What needs to be known is that the cesium tungsten bronze nano-powder is not really "transparent", but a dark blue powder. "Transparent" mainly means that the thermal insulation dispersion, thermal insulation film and thermal insulation coating prepared with cesium tungsten bronze all show high transparency.

Among them, the production of thermal insulation coatings requires the use of film formers, such as acrylic resins, experts said. Acrylic resin has excellent color and luster, good light and weather resistance, UV resistance, no decomposition or yellowing, gloss and color retention, and can maintain the original color for a long time. Acrylic resins are often used in combination with other resins as film-forming materials for transparent thermal insulation coatings. Some experts use polyurethane acrylate water-based resin as film-forming material and nano-cesium tungsten bronze as heat-insulating particles to prepare transparent heat-insulating coatings, which are applied to architectural glass. Studies have shown that the transmittance of coatings in the visible light region is about 75%.
