Description

technical field [0001] The invention relates to a nano-coating material, more specifically to a water-based high-transparency coating material with a composite inorganic nano-nuclear particle structure for heat insulation of transparent glass and a preparation method thereof, belonging to the field of coatings. The material can be used as a coating on glass surfaces such as architectural glass and automotive glass. Background technique [0002] Coating materials are solid continuous film materials coated on the surface of objects, which can be divided into many types such as wear-resistant type, anti-oxidation type, heat-insulating type, and light-transmitting type. Currently, due to the widespread use of glass in daily life, various coatings suitable for glass have been extensively studied. [0003] In building glass, on the one hand, as architectural lighting, it is expected to efficiently transmit visible light while reducing energy loss caused by thermal effects of indo...

Problems solved by technology

However, the visible light transmittance of the coating prepared by this technology is too low, even less than 60%.

[0017] Although many preparation methods of vanadium dioxide and doped vanadium dioxide coatings have been reported, such as chemical vapor deposition, reactive evaporation, magnetron sputtering, laser pulse deposition, sol-gel method, hydrothermal Synthesis method, vacuum reduction method, spray pyrolysis method, etc., but these methods have expensive raw materials, complicated preparation process, resulting in high preparation cost, and vanadium dioxide powder presents mixed valence state and low purity, which leads to its large-scale industrial application. there is a distance

[0018] Therefore, although there are various heat-insulating and light-transmitting coating composition materials in the prior art, their performance is still not perfect, and the too single function also restricts the application range of the material.
