Low Temperature-curable Ceramic Organic-Inorganic Hybrid Hydrophilic Coating Materials Composed of Metal Oxide Nanoparticles with Ultraviolet ray cutting off And Fabrication Method Thereof

摘要

The present invention relates to a method for producing a thin film coating agent for simultaneously imparting a surface superhydrophilic function and an optical ultraviolet ray blocking function to a coated object. The present invention is prepared by reacting an acid catalyst to a titanium alkoxide solution, the acid catalyst is divided into two steps to synthesize a titanium nanosol and a step of preparing a titanium oxide sunscreen coating comprising reacting an organic polysiloxane to the titanium nanosol. Provide a method. According to the present invention, when the film is dried at a temperature of 100 ^o C or less, the film hardness is more than pencil hardness of 5H or more (1kgf load, coating thickness 2m or less), the water contact angle is less than 10 ^o , the light transmittance in the visible region is more than 80% energy A coating agent having a performance of blocking at least 90% of ultraviolet rays having a wavelength of 340 nm or less can be provided.
