Embodiment 1

[0015] Add 0.05 moles of triadimenol, 0.075 moles of triethylamine and 100ml of chloroform into the Erlenmeyer flask, place them on a magnetic stirrer and stir to dissolve, cool to 0~5°C, slowly add dropwise a chloroform solution containing 0.06 moles of acryloyl chloride 50ml, after the dropwise addition is completed within 60 minutes, naturally warm to room temperature, and continue to stir and react for 24 hours, filter, collect the filtrate, and concentrate the filtrate by distillation to obtain a brown-red viscous liquid. Add 30ml of methanol to the viscous liquid to make it uniformly dissolved. Then it was added to 200ml deionized water while stirring to precipitate a white solid, filtered, the filter cake was dissolved in 50ml methanol, and then added to 200ml deionized water while stirring, a white solid precipitated, filtered, and the filter cake was vacuum dried to a constant temperature. After heavy, crushed, elemental analysis and infrared spectroscopy analysis, the ...

Embodiment 2

[0018] The preparation method of tebuconazole acrylate monomer is the same as in Example 1, except that the triadimenol is replaced with tebuconazole, and the product yield is 86.6%. In a 500ml four-necked flask equipped with a reflux condenser and a thermometer, 150ml of N,N-dimethylformamide was added, 20g of tebuconazole acrylate monomer, 69g of methyl methacrylate, 21g of butyl acrylate and 1g were added Azobisisobutyronitrile, stir and heat up to 80℃ while blowing nitrogen gas, keep the temperature at 82±2℃ for 5 hours, and cool down to obtain a light yellow, clear and transparent side chain polyacrylate bactericidal copolymer resin containing triazole bactericide structure 2.

Embodiment 3

[0020] The preparation method of triadimenol acrylate monomer is the same as that in Example 1, except that triadimenol is replaced with triadimenol, and the product yield is 91.4%. Into a 500ml four-necked flask equipped with a reflux condenser and a thermometer, add 150ml of N,N-dimethylformamide, add 21g of flutriazole acrylate monomer, add 69g of methyl methacrylate, 20g of butyl acrylate and 1g Azobisisobutyronitrile, stir and heat up to 80℃ while blowing nitrogen gas, keep the temperature at 82±2℃ for 5 hours, and cool down to obtain a light yellow, clear and transparent side chain polyacrylate bactericidal copolymer resin containing triazole bactericide structure 3.

Abstract

The invention relates to a polyacrylate sterilization copolymer resin with a triazole structure on a side chain and a preparation method thereof. The preparation method comprises the following steps of firstly, synthesizing an acrylate functional monomer with the triazole structure; and secondly, performing a solution copolymerization reaction on the functional monomer and other one or two or three alkenyl monomers, and thus obtaining the light yellow, clear and colorless polyacrylate sterilization copolymer resin with the triazole structure on the side chain. The sterilization copolymer resin has good antifouling performance and self-polishing performance when used as a film-forming agent for antifouling paint, and a resin preparation process is simple and practical.

Description

Technical field [0001] The invention relates to a polyacrylate bactericidal copolymer resin, in particular to a polyacrylate bactericidal copolymer resin with a triazole structure in its side chain and a preparation method thereof. Background technique [0002] Triazole compounds are a class of heterocyclic compounds with a wide range of biological activities. They have good control effects on common fungal diseases and become the fastest-growing class of fungicides. In recent decades, triazole fungicides, such as triadimenol, tebuconazole, hexaconazole, fluconazole, ciproconazole, diniconazole and bifonconazole, are highly effective, low-toxic, systemic and The advantages of broad-spectrum sterilization have attracted the attention of researchers, and it has become an important type of fungicide widely used. The bactericidal properties of triazole compounds come from the triazole ring, which is easy to accept protons and complex metal ions. When the triazole bactericide enters ...
