Embodiment Construction

[0010] 1. Preparation of 1-acryloyl indole monomer

[0011] Put 50mL of freshly steamed tetrahydrofuran, 3.5g of 1-hydroindole, and 3.9g of sodium cyanide into a three-neck flask successively, and react at room temperature for 30 minutes to obtain indole sodium salt. Dissolve 3.3 g of acryloyl chloride in 10 mL of tetrahydrofuran, drop it into the indole sodium salt prepared above, control the reaction temperature at 0° C., and react for 2.5 hours to obtain 1-acryloyl indole monomer.

[0012] Replace the above-mentioned 1-hydroindole with haloindole, 1-hydrohydrophylline or halocarpine, and follow the above-mentioned preparation method to obtain 1-acryloyl haloindole, 1-acryloyl Alkaline or 1-acryloylhalocarpine monomer.

[0013] 2. Preparation of acrylic resin containing indole functional groups and carboxyl groups

[0014] Add toluene and n-butanol in a three-necked flask equipped with a stirring device, a condenser, and a thermometer. Their weight ratio is 262g of a mixed...

Abstract

This is a kind of acrylic zinc or cuprum resin containing indole functional group and its preparation method. Its characteristics are: firstly prepare monomer containing indole functional group, then synthesize acrylic resin containing functional group and carboxyl, finally make the acrylic resin and zinc hydroxide or cuprum hydroxide react to obtain acrylic zinc or cuprum resin containing indole functional group; the reaction temperature of the said synthesizing monomer containing indole functional group is -10 - 10 Deg. C, the reaction time is 1.5 - 5 hours. The resin of the invention can be used for preparing sea antifouling dope. In the seawater, the organic zinc or cuprum acrylic ester on the polymer linear main chain of the coat surface hydrolyzes, and send out organic zinc or cuprum; the hydrolyzed polymer main chain contains indole functional group with highly efficient antifouling activeness, which makes the hydrolyzed polymer main chain still has sterilization activeness. So the dope can effectively prevent halobios from clinging on the surface of fishing tools, ships and seacoast establishments, and has good antifouling performance.

Description

technical field [0001] The invention relates to a zinc or copper acrylate resin, in particular to a zinc or copper acrylate resin containing an indole functional group, a preparation method thereof and an application in preparation of marine antifouling paint. technical background: [0002] There are thousands of fouling organisms in the ocean, and more than half of these fouling organisms float on the coast and harbors. They attach and grow on the bottom of ships, buoys, water pipelines, cooling pipelines, rafts and nets. The attachment of these fouling organisms will cause the surface fouling of these facilities, increase the surface friction resistance, and also accelerate the corrosion rate. The most common solution to marine biofouling is to apply paints containing antifouling agents. At present, a large number of antifouling coatings used at home and abroad contain organotin and cuprous oxide, such as the copolymer of tributyltin methacrylate and methyl methacrylate a...
