Problems solved by technology

Since Seanine 911 is added to the coating with small molecules, according to Fick’s diffusion law, the antifouling agent in the coating is released too quickly at the initial stage of coating, and the antifouling effect of the coating will decrease after the ship sails for a period of time. It is difficult for antifouling coatings to achieve uniform and controlled release of antifouling agents like tin-containing self-polishing antifouling coatings, resulting in a relatively short antifouling period

Embodiment 1

[0008] In a 500ml four-necked flask equipped with a reflux condenser and a thermometer, add 150gN, N-dimethylformamide, add 100g epoxy resin E-51, 15g N-acryloyloxymethyl benzisothiazolinone, 65g of methyl methacrylate, 20g of butyl acrylate, and 2g of azobisisobutyronitrile were heated up to 90°C while stirring with nitrogen gas, kept at 92±2°C for 5 hours, and cooled to obtain light yellow, clear and transparent Acrylate grafted epoxy resin with benzisothiazolinone structure1.

Embodiment 2

[0010] In a 500ml four-necked flask equipped with a reflux condenser and a thermometer, add 150g N, N-dimethylformamide, add 100g epoxy resin E-44, 15g N-methacryloxymethylbenzisothiazoline Ketone, 61g of methyl methacrylate, 24g of butyl acrylate, 2g of azobisisobutyronitrile, stirring and raising the temperature to 90°C while blowing nitrogen gas, keeping the reaction at 92±2°C for 5 hours, cooling down to obtain light yellow and clear Transparent acrylate-grafted epoxy resin containing benzisothiazolinone structure2.

Embodiment 3

[0012] In a 500ml four-neck flask equipped with a reflux condenser and a thermometer, add 150g N,N-dimethylformamide, add 100g epoxy resin E-51, 15g N-methacryloxymethylbenzisothiazole Linone, 55g methyl methacrylate, 20g butyl acrylate, 10g vinyl acetate, 1.5g azobisisobutyronitrile, stirring while nitrogen gas is heated up to 80°C, and the temperature is kept at 82±2°C for 5 hours, and the temperature is lowered. The light yellow, clear and transparent acrylate-grafted epoxy resin 3 containing benzisothiazolinone structure was obtained.

Abstract

The invention relates to an acrylic ester grafted epoxy resin containing a benzisothiazolinone structure and a preparation method thereof. In an organic solvent, a mixed monomer composed of N-substituted acryloxymethyl benzisothiazolinone functional monomer and other one or two or three alkenyl-containing monomers is applied to graft copolymerization reaction of the epoxy resin to obtain the clear and transparent acrylic ester grafted epoxy resin containing the benzisothiazolinone structure. The anti-fouling resin serves as the film-forming agent of the anti-fouling coating, and has excellent anti-fouling performance and self-polishing performance; and the resin preparation process is simple and feasible.

Description

technical field [0001] The invention relates to an acrylate grafted epoxy resin, in particular to an acrylate grafted epoxy resin containing a benzisothiazolinone structure and a preparation method thereof. Background technique [0002] The attachment of marine fouling organisms has caused serious harm to ships and marine facilities, and brought huge economic losses to human beings. The most direct way to solve this problem is to apply antifouling paint. Isothiazolinone fungicides have strong bactericidal activity, can widely inhibit the growth of various microorganisms at a concentration of about 0.5-1ppm, and can quickly biodegrade and are environmentally safe, so they are widely used in industrial circulating cooling water, Textile, paint, agriculture, forestry and environmental protection and other fields. In the 1990s, Rohrnhaas Company of the United States successfully developed 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (Seanine 911), and used it as an efficient ant...
