Embodiment 1

[0019] The surface of the original glass sheet is atomized and corroded with hydrofluoric acid to form micropores with a dense pore size, pore distance, and pore depth of 20 to 100 nanometers, and then rinsed with foam detergent, ultrasonic waves and deionized water, and pressurized pressure. , sent to the heat treatment furnace for 1 hour at 650°C, air-cooled and kept at 200-100°C, and then sent to the coated glass production line, using nano-scale Tio 2 The target material is coated with a film layer of 15-100nm on its surface.

Embodiment 2

[0021] Put 100ml of methanol into the reaction tank, then add 20ml of butyl titanate while stirring, stir and mix in a sealed container for 3 to 5 hours, then add 2ml of ethyl silicate and 50ml of ethanol, and continue to mix and stir for 24 hours to obtain Tio 2 / Sio 2 Sol, set aside after 48 hours.

[0022] The surface of the original glass sheet is atomized and corroded with phosphoric acid to form micropores densely covered with pore diameter, pore distance, and pore depth of 20 to 100 nanometers, scrubbed with foam detergent, and then sprayed with ultrasonic waves, 1Mpa air pressure and deionized water Clean it up, put it into the heat treatment furnace and dry it at 150-200°C, and use Tio 2 / Sio 2 The sol is sprayed on the glass surface at a constant speed to form a coagulation film layer, and then sent to a heat treatment furnace at a temperature of 450-650 ° C for 1-2 hours to solidify the film and temper it, so that the glass surface forms nano-scale Tio 2 / Sio 2...

Embodiment 3

[0024] The surface of the original glass sheet is drilled by laser scanning, densely covered with micropores with a diameter, distance, and depth of 20 to 100 nanometers, and then the glass is cleaned with foam detergent, ultrasonic waves and deionized water, air pressure spraying, and sent to heat treatment After drying in the oven at 100-200°C, use Tio 2 / Sio 2 The sol is sprayed at a constant speed on the glass surface to form a condensation film layer, and then sent to a heat treatment furnace. After solid film treatment at a temperature of 450-650 ° C for 1 hour, it is air-cooled and annealed to form a nano-scale Tio 2 / Sio 2 film.

Abstract

The disclosed process technique for nano-level self-cleaning coated glass comprises: etching or laser drilling on glass surface to obtain micro pores with size, distance and depth all within 20-100nm; coating SiO2 / TiO2 nano gel film or Ti film or nano Ag film all with super light transmission, hydrophilicity and lipophilicity for self cleaning activated UV ray. This invention has wide application.

Description

Technical field: [0001] The invention relates to a special-performance glass, in particular to a nano-scale self-cleaning coated glass and a production process, and belongs to the technical field of deep processing of glass products. Background technique: [0002] Traditional architectural glass, safety glass, coated glass, and insulating glass do not have self-cleaning performance. The existing gel coating or coating methods are difficult to solve the problem of self-cleaning glass production process. Invention content: [0003] The self-cleaning coated glass and the production process of the invention aim at solving the self-cleaning problem of the glass surface. [0004] The process technology of the present invention is: after making micropores on the glass surface, the bonding strength of the coating film is improved, and the surface of the original glass sheet is treated with acid-etched micropores or laser drilling to form densely distributed pores with a diameter, ...
