Embodiment Construction

[0010] 1. Preparation of N-(4-hydroxy-3-methoxy-benzyl)-acrylamide (HMBA) monomer

[0011] Accurately measure 100ml of absolute ethanol in a 250ml single-necked flask, slowly pour 10ml of concentrated sulfuric acid into it, then weigh 40g of N-methylolacrylamide and 50g of guaiacol respectively and add them to the above flask, shake well, and React at 35°C for 7 days. It was shaken vigorously every 5 hours during the reaction. After the reaction, a large amount of white solids were precipitated in the system. The solid therein was filtered off and washed with water until the pH value of the filtrate was neutral. Recrystallized from ethanol to obtain colorless needle-like crystals. The dry weight of the obtained solid N-(4-hydroxyl-3-methoxy-benzyl)-acrylamide was 33.9g, the yield was 26.6%, and the melting point was 146-147°C. 1 H-NMR and infrared spectroscopy confirmed that the product was HMBA.

[0012] Replace the above-mentioned guaiacol with o-chlorophenol, o-bromoph...

Abstract

This is a kind of acrylic zinc or cuprum resin containing capsaicin functional group and its preparation method. Its characteristics are: firstly synthesize monomer containing capsaicin 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 capsaicin functional group. 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 capsaicin 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 capsaicin functional groups, a preparation method thereof and an application in preparation of marine antifouling paints. Background technique [0002] Various marine organisms are often attached to the surface of nets, hulls, and underwater facilities soaked in seawater for a long time, which will cause surface fouling, increase surface friction resistance, and accelerate corrosion. The most common solution to marine biofouling is the application of paints containing antifouling agents. At present, the antifouling agents widely used at home and abroad contain organotin and cuprous oxide. The copolymer of tributyltin methacrylate and methyl methacrylate and cuprous oxide (Cu 2 O) the composition is used as a kind of antifouling paint, is coated on surfaces such as the bottom of a ship, and can effectively prevent the harm of marine fou...
