Embodiment 1

[0015] Implementation 1: Fabrication of SiO 2 Thin touch and TiO 2 The raw materials of the photocatalytic film are all organic materials.

[0016] Deposition of SiO in transition raceway area 2 , after atomizing silicone grease or silane (quantity 20ml / l), it is brought into the top of the glass in the transition raceway area by the carrier gas to realize SiO at a temperature of 550°C. 2 production. The time for the glass to move through this spray area should be 1 minute, and the carrying gas is Ar, N 2 , O 2 of mixed gas.

[0017] Deposit TiO in zone A of the annealing process 2 Thin film, first ultrasonically atomize the titanium grease (quantity 40ml / l), and then bring it into the glass in area A by the carrier gas (at this time, SiO has been deposited on the glass 2 thin film) to achieve TiO 2 Film production. The time for the glass to move through this spray area is 1 minute, and the temperature is 500°C. Carrying gas is Ar, N2, O 2 of mixed gas. Finally, a ...

Embodiment 2

[0018] Implementation 2: Preparation of SiO 2 The thin film uses organic raw materials to prepare TiO 2 The film uses inorganic raw materials.

[0019] Basically the same as implementation 1. The difference is: deposited SiO 2 The time is 1 minute and the temperature is 550°C; TiO is deposited in the B and C areas of the annealing process 2 For the film, the raw material is metatitanic acid or fluorotitanic acid or titanyl sulfate (concentration expressed as titanium dioxide is 10g / l), the temperature is 400°C, and the time for the glass to pass through the atomization area should be 2 minutes. Finally, a photocatalytic superhydrophilic film with a thickness of 0.5 μm was deposited on the glass plate.

Embodiment 3

[0020] Implementation 3: Preparation of SiO 2 or SnO 2 or ZnO and TiO 2 The films are all made of corresponding inorganic raw materials.

[0021] Basically the same as implementation 1. The difference is: deposited SiO 2 or SnO 2 Or for ZnO, the time is 2 minutes, the temperature is 610°C, and the raw material is SiCl 4 or silicic acid or SnCl 4 or ZnCl 2 (quantity 20g / l); Deposit TiO in zones B and C of the annealing process 2 Film, the temperature is 300°C, the time for the glass to pass through the atomization area should be 2 minutes, and the carrying gas is compressed air. Finally, a photocatalytic superhydrophilic film with a thickness of 1 μm was deposited on the glass plate.

Abstract

The invention relates to an online production method of self-cleaning glass, which is used in the fields of buildings, various showcases, vehicles, daily necessities and the like. This method increases the preparation of SiO in the transition raceway area and the annealing area of ​​the existing float glass production line. 2 or SnO 2 or ZnO and TiO 2 Thin film atomization and spraying process; among them: SiO 2 or SnO 2 or ZnO and TiO 2 The raw materials of the film are organic or inorganic raw materials, the organic raw materials are silicone grease or silane and titanium grease, and the inorganic raw materials are SiCl 4 or silicic acid or SnCl 4 or ZnCl 2 and metatitanic acid or fluotitanic acid or titanyl sulfate, SiO 2 or SnO 2 or ZnO and TiO 2 The thickness of the film is 0.05-1μm; the time for the glass to pass through the spray area is 1-2 minutes, the temperature is 610°C-300°C, and the carrying gas is Ar, N 2 , O 2 of mixed gas. The method realizes the continuous production of the self-cleaning glass, and has the advantages of simplicity, low cost, good economic benefit and the like.

Description

Technical field: [0001] The invention relates to a method for making self-cleaning glass, which is used in the fields of buildings, various showcases, vehicles, daily necessities and the like. Background technique [0002] Glass is widely used in architecture, display windows, vehicles and many other fields. At present, the known glass is prone to water mist, affecting the clarity of vision; easy to stick to oil and dust, affecting transparency and external appearance. Photocatalytic self-cleaning glass is to make a layer of TiO on the surface of ordinary glass 2 It is a photocatalytic superhydrophilic film, which makes the glass surface have photocatalytic and superhydrophilic properties. TiO 2 Its photocatalytic properties can decompose organic pollutants and harmful gases attached to it, and at the same time have antibacterial, anti-ultraviolet and other functions; its superhydrophilicity can spread the water droplets attached to it to form a water film, The pollutant...
