Problems solved by technology

However, the cleaning of the glass curtain wall is a headache. It is not only dangerous but also wastes a lot of water resources and causes certain environmental pollution due to the use of detergents. The use of self-cleaning glass that relies on natural rainwater is fundamentally The most effective way to solve the above problems, therefore, research on the preparation of self-cleaning glass has become a hot research topic in this area

Embodiment approach

[0027] 1. Clean the float glass substrate with a self-made surfactant washing solution, rinse it with deionized water, dry it, and set it aside;

[0028] Second, the prepared TiO 2 The composite sol is poured into the sprayer, and the spraying speed is controlled to be 1.0m / min to spray TiO on the moving glass substrate at a speed of 1.5m / min. 2 Composite sol;

[0029] Three, will be sprayed with TiO 2 The glass substrate of the composite sol is dried at a temperature of 105°C to form TiO 2 Self-cleaning film, the TiO in the film layer 2 The particle diameter is about 30nm, the film thickness is 53nm, with nano TiO 2 characteristic;

[0030] 4. After aging at 300°C for 10 minutes, TiO-coated 2 The self-cleaning glass of the self-cleaning film has good hydrophilicity, and the water contact angle of the glass surface is θ=0°; the transparency is good, and the visible light transmittance is 85.3%. Under the irradiation of visible light, the time for methyl orange to decompo...

Abstract

Production of self-cleaning glass is carried out by cleaning glass substrate, drying, pouring the prepared TiO2 sol into atomizer, spraying glass substrate surface with TiO2 composite sol at 1.0-2.5m / min, drying at 60-150 degrees C, and aging at 300 degrees C to obtain self-cleaning glass with TiO2 self-cleaning membrane. It has better super-hydrophilic property and self-cleaning ability.

Description

technical field [0001] The utility model relates to a method for preparing glass, in particular to a method for preparing self-cleaning glass. Background technique [0002] Glass curtain wall is favored by architects because of its advantages of windproof, rainproof, heat preservation, heat insulation, noise prevention, air penetration resistance and decoration, and has become a symbol of urban modernization. However, the cleaning of the glass curtain wall is a headache. It is not only dangerous but also wastes a lot of water resources and causes certain environmental pollution due to the use of detergents. The use of self-cleaning glass that relies on natural rainwater is fundamentally The most effective way to solve the above problems, therefore, research on the preparation of self-cleaning glass has become a hot topic in this area. [0003] Many studies have shown that: TiO 2 Under the condition of ultraviolet light, the film has the functions of super hydrophilic, deco...
