Embodiment 1

[0023] The preparation method of the antifouling self-cleaning coating material, the specific steps are as follows:

[0024] (1) Graphite powder with a mass ratio of 1:0.8:0.8, K 2 S 2 O 8 and P 2 O 5 Add it to 24 mL of concentrated sulfuric acid with a mass concentration of 98%, react at 85°C for 4 hours, then cool to 30°C, add 1000 mL of ultrapure water, leave it for 12 hours, wash the product until it is neutral, and place it at 50°C After drying, pre-oxidized graphite was obtained; the pre-oxidized graphite was added to 240 mL of concentrated sulfuric acid with a mass concentration of 98%, and then NaNO with a mass ratio of 1:6 was added. 3 and KMnO 4 , react at 0 °C for 3 hours, heat up to 35 °C for 2 hours, add 500 mL of ultrapure water, react at 95 °C for 1 hour, then add 1000 mL of ultrapure water and 40 mL of 30% H 2 O 2 , continue the reaction for 2 hours, wash the obtained product with a HCl solution with a mass concentration of 10%, wash it with a large amou...

Embodiment 2

[0028] The preparation method of the antifouling self-cleaning coating material, the specific steps are as follows:

[0029] (1) Graphite powder with a mass ratio of 1:0.8:0.8, K 2 S 2 O 8 and P 2 O 5Add it to 24 mL of concentrated sulfuric acid with a mass concentration of 98%, react at 85°C for 4 hours, then cool to 30°C, add 1000 mL of ultrapure water, leave it for 12 hours, wash the product until it is neutral, and place it at 50°C After drying, pre-oxidized graphite was obtained; the pre-oxidized graphite was added to 240 mL of concentrated sulfuric acid with a mass concentration of 98%, and then NaNO with a mass ratio of 1:6 was added. 3 and KMnO 4 , reacted at 0 °C for 3 hours, raised the temperature to 35 °C for 2 hours, added 500 mL of ultrapure water, and reacted at 90 °C for 5 hours, then added 1000 mL of ultrapure water and 40 mL of 30% H 2 o 2 , continue the reaction for 2 hours, wash the obtained product with a HCl solution with a mass concentration of 10%...

Embodiment 3

[0033] Embodiment 1 The method for applying an antifouling self-cleaning material to a glass surface, comprising the following steps: using a glass abrasive to remove the oil stain on the glass surface to be coated, cleaning the glass surface with ethanol for 3 times, and drying it naturally for 2 hours, and applying the antifouling self-cleaning material to the glass surface. Apply the cleaning material evenly on the glass surface with a glass scraper, and let it dry naturally for 24 hours.

[0034] The result shows that after spraying the antifouling self-cleaning material in the present invention, the water droplet contact angle is less than 5 degrees, and the cleaning effect is as follows: figure 1 shown.

Abstract

The invention provides an anti-fouling self-cleaning material and a preparation method and application thereof. The material comprises hydrophilic silicon oxide, titanium dioxide with oleophobicity, graphene oxide and tin oxide with conductivity, and lamellar g-C3N4 with visible-light photocatalytic capacity; the mass ratio of graphene oxide to lamellar g-C3N4 to silicon oxide to tin oxide to titanium dioxide is 1:(1-50):(0.5-10):(10-500):(10-500). According to the anti-fouling self-cleaning material, the applied raw materials are easy to obtained and low in price; the material has the high hydrophilicity and photocatalytic capacity, and the anti-fouling self-cleaning effect can be achieved; preparation method is simple, large-scale mechanical equipment or manpower and material resources are not needed, and mass production can be achieved.

Description

technical field [0001] The invention belongs to the field of self-cleaning materials, in particular to a material used for anti-fouling and self-cleaning on the surface of glass materials. Background technique [0002] With the development of the economy, various new buildings emerge as the times require, and many high-rise buildings are increasingly favored by the use of glass curtain walls. Due to the influence of atmospheric smog, dust layer, nitrogen oxides and sulfur oxides, and acid rain, a large amount of pollutants will accumulate on the surface of the glass curtain wall, which will reduce its permeability and affect the appearance of the building. At present, the main cleaning method for glass curtain walls in my country is manual cleaning. This method consumes a lot of manpower and financial resources, and there are also safety issues for cleaning personnel. Moreover, the stain resistance of the cleaned glass is poor, and the glass curtain wall will be polluted ag...
