Embodiment 1

[0022] 1) Take 1 g of methoxypolyethylene glycol-b-polyethyl methacrylate dimethylsulfopropyl betaine-b-polydimethylaminoethyl methacrylate and 0.5 ml of 3-chloropropyl tris Ethoxysilane, dissolved in 20mL of methanol, heated to reflux at 60°C for 48h under the protection of nitrogen, the obtained polymer solution is the antifouling and antibacterial coating.

[0023] 2) Application

[0024] The glass sheet was soaked in 30wt% hydrogen peroxide / 98wt% sulfuric acid mixture (v / v, 3:7) for 24 hours, washed with water and ethanol four times in sequence, and dried and activated at 100°C for 3 hours.

[0025] Immerse the activated glass piece in the polymer solution for 2 hours, take it out and let it dry naturally, that is to say, a polymer coating with antifouling and antibacterial properties is prepared.

Embodiment 2

[0027] 1) Take 0.8 g of methoxypolyethylene glycol-b-polyethyl methacrylate dimethylsulfopropyl betaine-b-polydimethylaminoethyl methacrylate and 0.5 ml of 3-chloropropyl tris Ethoxysilane, dissolved in 15mL of methanol, heated to reflux at 50°C for 36h under the protection of nitrogen, the obtained polymer solution is the antifouling and antibacterial coating.

[0028] 2) Application

[0029] The glass sheet was soaked in 30wt% hydrogen peroxide / 98wt% sulfuric acid mixture (v / v, 3:7) for 12 hours, rinsed with water and ethanol three times in sequence, and dried and activated at 100°C for 3 hours.

[0030] Immerse the activated glass piece in the polymer solution for 2 hours, take it out and let it dry naturally, that is to say, a polymer coating with antifouling and antibacterial properties is prepared.

Embodiment 3

[0032] 1) Take 0.8 g of methoxypolyethylene glycol-b-polyethyl methacrylate dimethylsulfopropyl betaine-b-polydimethylaminoethyl methacrylate and 0.5 ml of 3-chloropropyl tris Ethoxysilane, dissolved in 15mL of methanol, heated to reflux at 60°C for 36h under the protection of nitrogen, the obtained polymer solution is the antifouling and antibacterial coating.

[0033] 2) Application

[0034] Mix 30wt% hydrogen peroxide and 98wt% sulfuric acid in a volume ratio of 3:7 to prepare a mixed treatment solution;

[0035] Clean the surface with a mixed treatment solution according to the area to be coated; then rinse with water and ethanol for 3 times;

[0036] Dry and activate the washed glass sheet to be coated for 3 hours at a temperature of 80°C;

[0037] Brush the surface of the activated glass sheet and let it dry naturally to prepare a polymer coating with antifouling and antibacterial properties.

Abstract

The invention discloses an antifouling and antibacterial coating paint, which is prepared by taking methanol as a solvent through carrying out quaterisation reaction on copolymers methoxy polyethylene glycol-b-poly(ethyl methacrylate) dimethyl sulfo-propane betaine-b-poly dimethylaminoethyl methacrylate and 3-triethoxysilane. The invention also discloses applications of the paint in preparing coatings on the surfaces of ships, marine engineering machineries and sewage treatment equipment so as to implement antifouling and antibacterial treatment. Experiments show that a polymer coating prepared by using the paint disclosed by the invention has excellent protein adsorption and microbial contamination resistance, and has lasting antifouling and antibacterial abilities, and therefore, the paint has a board market prospect, and has significant social and economic values.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials, and relates to an antifouling and antibacterial coating and its application. Background technique [0002] Polymers have good film-forming properties, mechanical strength, chemical and thermal stability, and corrosion and oxidation resistance. They are one of the most commonly used coating materials. However, in the fields of marine, biochemical, food and water treatment, polymer coatings Issues such as pollutant damage and bacterial erosion on the surface need to be solved urgently. Taking the polymer materials used in marine engineering as an example, various marine microorganisms are very easy to adhere to the polymer surface, grow, reproduce, secrete proteins and polysaccharides, and form stubborn biofilms on the surface, affecting their performance and accelerating its destruction. Although taking pretreatment measures can alleviate the problem, it is difficult to solv...
