Cesium tungsten bronze powder may be used for the preparation of transparent thermal insulation material, which may be applied to architectural glass, car window glass, and the like. So, the glass obtained can block ultraviolet rays and near-infrared rays to a large extent while ensuring the passage of visible light. It is well known that excessive ultraviolet radiation is highly susceptible to skin diseases and even skin cancer. Also, excessive ultraviolet is easy to accelerate the aging of furniture, accessories, and carpets. And near-infrared rays are the main culprit in causing heat. Therefore, such new transparent heat insulating material is gradually being used in various fields of heat insulation.
Some experts have studied the preparation method of this kind of glass transparent heat-insulating coating, and successfully found the following preparation method: Weigh 0.272g of cesium tungsten bronze powder, fully grind in 2mol/L, 10ml citric acid for 5min, then ultrasonically disperse for 20min, repeatedly grinding, ultrasonic 3 times, to obtain a uniform slurry; add the slurry into 10ml of the prepared PVA slurry, stirred in a water bath at 80°C for 30min, and then placed for 2d, and the transparent heat insulation coating of cesium tungsten bronze is obtained.
