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 functional material technology and glass processing field, concretely discloses a permanent self-cleaning glass with visible light response and method for making it. Firstly, sputtering silica dioxide film on the surface of glass, sputtering a layer of titanium oxide film with anion and cation codoping on the surface of silica dioxide film, annealing the glass with twin layer films at 500-600 DEG C, cooling by radiation in sintering stove, to get the product. The self-cleaning glass has good photocatalysis property and photo-induced hydrophilicity, stable performance, almost perpetual availability, high light transmittance ratio and transparency. It is widly used in glass curtain wall of skyscrapers, automobile glass, road lamp shade, kitchen galss and antifog glass, avoiding artificial cleaning indoor and outdoor glass of skyscrapers, saving manual power and material, reducing corrosion destruction of cleaning agent to glass and building machinery, embodying environment protection notion.

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...
