Embodiment 1

[0026] (1) Under a nitrogen atmosphere, add 0.21g of RAFT reagent, 7.5g of polyethylene glycol methyl ether acrylate, 0.5g of methyl acrylate, 0.04g of AIBN, and 12g of anisole into a 100ml three-necked flask. At a temperature of 60° C., react for 5 hours, and precipitate to obtain a macromolecular chain transfer agent.

[0027] (2) Then take 0.8g of macromolecular chain transfer agent, add 0.92g of perfluorosulfonamidoethyl acrylate, 0.006g of AIBN, and 5.17g of butyl acetate, and react at a temperature of 70°C for 10 hours to obtain amphiphilic fluorine-containing Block copolymer resins.

Embodiment 2

[0029] (1) Under a nitrogen atmosphere, add 0.80g of RAFT reagent, 5g of polyethylene glycol methyl ether methacrylate, 15g of methyl acrylate, 0.10g of AIBN, and 55g of phenylene ether into a 100ml three-necked flask. At a temperature of 70° C., react for 4 hours, and precipitate to obtain a macromolecular chain transfer agent.

[0030] (2) Then take 1.6g of macromolecular chain transfer agent, add 2.0g of perfluorosulfonamidoethyl methacrylate, 0.01g of AIBN, and 10.2g of butyl acetate, and react at a temperature of 80°C for 10 hours to obtain amphiphilic Fluorinated block copolymer resin.

Embodiment 3

[0032] (1) Under a nitrogen atmosphere, add 0.63g of RAFT reagent, 3.82g of polyethylene glycol methyl ether methacrylate, 10.8g of methyl acrylate, 0.09g of AIBN, and 43.5g of anisole into a 100ml three-necked flask. At a temperature of 80° C., react for 4 hours, and precipitate to obtain a macromolecular chain transfer agent.

[0033] (2) Then take 1.2g of macromolecular chain transfer agent, add 1.8g of perfluorosulfonamidoethyl methacrylate, 0.009g of AIBN, and 9.5g of butyl acetate, and react at a temperature of 90°C for 8 hours to obtain amphiphilic Fluorinated block copolymer resin.

Abstract

The invention relates to an amphiphilic fluorine-containing block copolymer resin, and a preparation method and application thereof. The structural general formula of the amphiphilic fluorine-containing block copolymer resin is as shown in formula (1). In the formula, R=CH3 or H; x=15.0-50.0, y=3.0-20.0, z=3.0-10.0, p=1 or 4, m=3.0-25.0, and n=3 or 5; and X is -(CH2)k- or -(CH2)k-N(ChH2h+1)-SO2-. The amphiphilic fluorine-containing block copolymer resin is prepared through a two-step reversible addition-fragmentation chain transfer-free radical polymerization (RAFT) method. The method comprises the following steps: preparing a random copolymer from a hydrophilic monomer and a hydrophobic monomer, and adding fluorine-containing components into the random copolymer serving as a macromolecular chain transfer agent to generate the amphiphilic fluorine-containing block copolymer. The amphiphilic fluorine-containing block copolymer resin is simple in preparation process, non-toxic, harmless and favorable in anti-fouling effect, and can be used for preparation of base materials of marine anti-fouling paint. Formula (1) is shown in the specification.

Description

technical field [0001] The invention relates to an amphiphilic fluorine-containing block copolymer resin applicable to marine antifouling and a preparation method thereof. Background technique [0002] As a special functional protective coating, marine antifouling coatings are used to coat the bottom of ships, marine structures, offshore oil platforms, submarine oil pipelines, etc., to prevent marine organisms from attaching and fouling, and reduce the pollution caused by biofouling. huge economic loss and environmental damage. [0003] The development of marine antifouling coatings has experienced the development process from traditional antifouling coatings to environmentally friendly antifouling coatings. The antifouling agents used in traditional antifouling coatings are toxic and have caused great harm to the environment and ecosystems. Countries around the world have banned them one after another. Now the development trend of marine antifouling coatings is non-toxic a...
