Embodiment 1

[0022] Cut the glass to the desired size. Clean the stains on the glass surface with water; soak the cleaned glass in the washing solution for 3 hours, and then use deionized water to ultrasonically clean it 5 times, 10 minutes each time. After cleaning, dry it with nitrogen; use radio frequency magnetron sputtering to sputter a layer of nano silicon dioxide film on the glass surface. The sputtering target is pure silicon dioxide, the sputtering atmosphere is pure argon, the sputtering pressure is 0.8Pa, the sputtering power is 180W, the glass substrate temperature is 150°C, the sputtering time is 4 hours, and the sputtering nanometer The thickness of silicon oxide film is about 30nm; titanium dioxide powder and tungsten trioxide powder are mixed and ball milled in proportion (the molar ratio of tungsten to titanium is 1:19), and then sintered at a high temperature in a sintering furnace; the surface is coated with nano silicon dioxide film The titanium dioxide hybrid target ...

Abstract

The invention belongs to the field of functional material technology and glass processing, and specifically discloses a permanent self-cleaning glass with visible light response and a preparation method thereof. Clean the glass surface, first sputter a silicon dioxide film on the glass surface, and then sputter a layer of anion and cation co-doped modified titanium dioxide film on the surface of the nano-silica film. Annealed at ℃ and naturally cooled in a sintering furnace. The self-cleaning glass has good photocatalytic property and photo-induced hydrophilicity under visible light, stable performance, almost permanent effect, high light transmittance, colorless and transparent. It can be widely used in the glass curtain wall of skyscrapers, automobile glass, street lamp shades, kitchen glass, and anti-fog glass, which can avoid manual cleaning of indoor and outdoor glass of skyscrapers, save manpower and material resources, and reduce the pollution caused by manual cleaning and the use of detergents. Corrosion and destruction of glass and building structures, embodying the concept of environmental protection.

Description

technical field [0001] The invention belongs to the field of functional material technology and glass processing, and specifically relates to a glass with visible light response and permanent self-cleaning performance prepared by a new functional material and a preparation method thereof. technical background [0002] Self-cleaning glass is a new type of glass material developed in recent years, which can be widely used in glass and glass products related to people's living environment. Such as architectural glass, curtain wall glass, partition glass, decorative glass, car windshield glass, car side window glass, reflector, skylight glass, lampshade glass, cover glass, hospital surgical equipment, kitchen glass, lens glass, home appliance glass , instrumentation glass, glass for special operations, etc. However, there are still some shortcomings in the development of self-cleaning glass at present. For example, its self-cleaning effect is poor, and it can only have self-cle...
