Problems solved by technology

However, the visible light transmittance of the coating prepared by this technology is too low, even less than 60%.
[0011] However, although there are various coating composition materials for insulating ultraviolet rays in the prior art, there are still few excellent glass coatings capable of temperature sensing and temperature control on the basis of insulating ultraviolet rays and high light transmittance, especially those only containing tungsten When the vanadium dioxide component is doped, high light transmittance has always been a difficult problem to solve (when the tungsten content is too low, the temperature control effect is poor, and the content is too high, resulting in low visible light transmittance)
Moreover, in the prior art, there is no material application that produces a synergistic effect with the phase transition characteristics of vanadium dioxide.

Description

technical field [0001] The invention relates to a nano-coating material, more specifically to an ultraviolet-insulating high-transparency temperature-controlled glass coating and a preparation method thereof, belonging to the field of coatings. Background technique [0002] At present, under the premise of the energy crisis, energy conservation and environmental protection have increasingly become one of the focuses of people's attention. Among them, more and more attention has been paid to the issue of building energy conservation. Due to the wide use of glass in architecture and life, people have conducted extensive research on various coatings suitable for glass. For example, glass wall curtains are increasingly used in modern buildings to achieve high light transmittance and good vision, but the infrared radiation from sunlight, especially in summer, increases the burden on air conditioning and leads to energy waste. Therefore, the use of nano-transparent heat-insulatin...
