Embodiment 1

[0022] The surface of the original reflective mirror is atomized and corrosively treated with nitrogen hydrofluoric acid to form olive pores densely covered with pore diameters, pore distances, and pore depths of 20-100 nanometers. Rinse it with air pressure, send it to a heat treatment furnace at 650°C for 1 hour, air-cool and keep it at 200-100°C, and then send it to the coated Borui production line, using nano-sized Ti0 2 The target is coated with a film layer of 15-100nm on its surface.

Embodiment 2

[0024] Put 100ml of methazine in the reaction tank, then add 20ml of butyl titanate while stirring, stir and mix in a sealed container for 3-5 hours, then add 2ml of ethyl silicate and 5Oml of methazine, and continue to mix and stir for 24 hours. Worth Si0 2 / Ti0 2 Sol, set aside after 48 hours.

[0025] The surface of the original reflective mirror is atomized and corroded with phosphoric acid to form micropores densely covered with pore diameters, pore distances, and pore depths of 20-100 nanometers, scrubbed with foam detergent, and then ultrasonic and 1Mp. The air pressure and deionized water are sprayed and cleaned, and sent to the heat treatment furnace to dry at 150-200°C and released, using Si0 2 / Ti0 2 The sol is sprayed on the surface of the reflective mirror 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 undergo solid film and tempering treatment, so that the s...

Embodiment 3

[0027] The surface of the original reflective mirror is drilled by laser scanning, densely covered with micropores with a diameter of 20-100 nanometers, and the depth of the hole is 20-100 nanometers. The reflective mirror is washed with foam detergent, and cleaned by ultrasonic waves, deionized water, and air pressure spray , sent to heat treatment furnace 100-200 ℃ after drying, with Si0 2 / Ti0 2 The sol is sprayed on the surface of the reflective mirror at a constant speed to form a condensation film layer, and then sent to a heat treatment furnace. After solid film treatment at 450-650°C for 1 hour, it is air-cooled and annealed and tempered to form nano-scale Si0 on the surface of the reflective mirror. 2 / Ti0 2 film.

Abstract

The present invention discloses a nanoscale self-cleaning car reflector and a production process. The reflector surface is subjected to an acid etching process or an laser drilling process to form an intensive micropore structure with pore diameter, pore pitch, and pore depth of 20-100 nm, and then is plated with a layer of nanoscale SiO2 / TiO2 sol film or a layer of nano titanium film or nano silver film. The film has a good refractive index, super hydrophilicity and super lipophilic. Oil or stain is subjected to a catalytic reaction of the film layer under the action of ultraviolet ray to decompose and drop to achieve the self-cleaning property. The product of the invention is an ideal material for producing self-cleaning car reflectors and self-cleaning electric heating anti-fog reflectors.

Description

technical field [0001] The invention relates to a reflective mirror with special performance, in particular to a nanoscale self-cleaning vehicle coated reflective mirror and its production process. Background technique [0002] Traditional architectural reflectors, safety reflectors, and coated reflectors do not have self-cleaning properties. The existing gel-coating or coating methods and electrostatic methods are difficult to solve the production process problems of self-cleaning reflectors. [0003] For example, a new method of electrostatic dust removal and its application disclosed in the patent application number 201110052100.x, the main content of which is: a new method of electrostatic dust removal. The present invention has two types of solid structure and mesh structure. The physical structure is to implant electrodes into the substrate using photolithography, abrasion and other technologies on the top of the insulating substrate, and then spray a thin layer o...
