Embodiment approach

[0028] a. Clean the float glass substrate with a self-made surfactant washing solution, rinse it with deionized water, air dry it, and set it aside;

[0029] b. Mix and prepare TiO according to the following components 2 Composite sol, the weight percentage of each component is: TiO 2 : SiO 2 : CeO 2 :H 2 O=20~30:0.1~1:0.02~0.1:65~70;

[0030] c, the prepared TiO 2 The composite sol is poured into the sprayer, and the speed of the single spray path 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;

[0031] d, 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;

[0032] e. After aging for 10 minutes at 300°C, TiO-coated 2 The self-cleaning glass of the self-cleaning film has good hydrophilicity, an...

Abstract

The invention discloses a method for preparing self-cleaning glass, which comprises the following steps: cleaning and air-drying a glass substrate; performing the mixing preparation of TiO2 composite sol according to the following components in the weight ratio of TiO2 to SiO2 to CeO2 to H2O being 20-30: 0.1-1: 0.02-0.1: 65-70; then pouring the prepared TiO2 composite sol into an atomizer, and spray-coating the TiO2 composite sol onto the surface of the glass substrate at a speed of between 1.0 and 2.5m / min; drying the position on the glass substrate spray-coated with the TiO2 composite sol at a temperature of between 60 and 150 DEG C; and aging the glass substrate at a temperature of 300 DEG C to obtain the self-cleaning glass coated with a TiO2 self-cleaning film. The TiO2 self-cleaning film has super-hydrophilicity under visible light conditions; and the surface of the glass can form an intact water film when encountering water, and has self-cleaning capability.

Description

technical field [0001] The invention 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, decompos...
