Embodiment 1

[0023] 1. Clean the glass surface with dilute hydrochloric acid, then clean it with deionized water, and dry it in an oven at 100°C.

[0024] 2. Use titanate, ethanol, water, hydrochloric acid, and triethanolamine as main components, and prepare titanium dioxide sol at a mass ratio of 1:5~20:2~5:0.1~1:0.2~2.

[0025] 3. Add Ag nanometer metal ions to the titania sol with a mass fraction of 0.2%.

[0026] 4. Place the cleaned and dried glass piece in the above solution, and lift it out of the solution at a speed of 1 mm / s after standing for 5 minutes.

[0027] 5. The coated glass is dried at 100°C, and then sintered in a muffle furnace at 700°C for 1 hour.

[0028] 6. Cool the coated glass treated in the above steps to obtain the photocatalytic antibacterial glass containing nano-silver.

Embodiment 2

[0030] 1. Clean the glass surface with dilute hydrochloric acid, then clean it with deionized water, and dry it in an oven at 100°C.

[0031] 2. Use titanate, ethanol, water, hydrochloric acid, and triethanolamine as main components, and prepare titanium dioxide sol at a mass ratio of 1:5~20:2~5:0.1~1:0.2~2.

[0032] 3. Add 0.2% Ag, 0.2% Zn nanometer metal ions into the titania sol.

[0033] 4. Place the cleaned and dried glass piece in the above solution, and lift it out of the solution at a speed of 1 mm / s after standing for 5 minutes.

[0034] 5. The coated glass is dried at 100°C, and then sintered in a muffle furnace at 700°C for 1 hour.

[0035] 6. Repeat steps 4-5 for the glass that has been coated with a layer of film, that is, place the glass piece again in the titanium dioxide sol containing metal ions, dip and pull, dry at 100°C, and then sinter in a muffle furnace at 700°C for 1 hour. Repeat this step twice to obtain glass coated with three layers of photocatalyt...

Abstract

The invention relates to a method for manufacturing self-cleaning photocatalysis antibacterial glass plated with a titanium dioxide photocatalysis layer and antibacterial metal ions. The method comprises the following steps: using a sol-gel method to prepare a photocatalysis film; performing cleaning pretreatment to the surface of glass; preparing titanium dioxide sol through titanium alkoxide hydrolysis; dispersing antibacterial nanometer metal ions in the titanium dioxide sol; adopting a dipping-pulling method to plate the glass; drying and then sintering the plated glass at a high temperature; and plating the glass for thickening. The method is characterized by simple process, no toxicity, quality control easiness, strong photocatalytic activity, high hardness, durability and the like.

Description

technical field [0001] The invention relates to a self-cleaning photocatalytic antibacterial glass and a production process thereof, belonging to the technical field of glass coating. Background technique [0002] In recent years, research on inorganic antibacterial materials is in the ascendant at home and abroad. The application field of antibacterial glass has gradually expanded from the original food and medical treatment to daily necessities, building materials, water treatment and other related fields. Therefore, antibacterial glass with different characteristics is gradually available in different fields. [0003] At present, the methods for manufacturing antibacterial glass materials include two categories: (1) Coating a layer of TiO with photocatalytic properties on the glass surface 2 coating. In order to prevent sodium ions on the glass surface from moving to TiO 2 The coating layer is diffused, and a layer of SiO is often coated on the glass surface 2 to pre...
