Embodiment 1

[0027] An antifouling coating is prepared from the following raw materials in parts by weight: 20 parts of modified acrylic resin, 1 part of capsaicin derivative, 3 parts of copper ion slow-release agent, 5 parts of rosin, 15 parts of filler, 0.5 parts of antioxidant 100 parts and solvent;

[0028] The copper ion sustained-release agent is prepared by the following method: 1mmol of CuSO 4 ·5H 2 O and 8 mmol of dimethylaminoethyl methacrylate were dissolved in 200ml of methanol, and after stirring at room temperature for 12 h, the solvent methanol was removed, and the remaining solid was washed with acetone for 3 times to remove excess dimethylaminoethyl methacrylate, and depressurized at room temperature Dry for 12h to obtain copper ion sustained-release agent;

[0029] 1 mmol CuSO 4 • 5H 2 O and 8mmol of dimethylaminoethyl methacrylate were dissolved in 200ml of methanol and reacted after mixing. The color of the solution changed from light blue to dark green rapidly, and...

Abstract

The invention discloses antifouling paint which is prepared from the following raw materials: modified acrylic resin, a capsaicin derivative, a copper ion slow release agent, rosin, a filler, an antioxidant and a solvent. The capsaicin derivative can repel and kill microorganisms, so that the microorganisms are difficult to get close, and microbial pollution is reduced; a copper ion complex in thepaint serves as a second defensive line, copper ions can be continuously and uniformly released, the retention time of the copper ions on the surface is prolonged, and the durability of the antifouling and antibacterial properties of the paint is enhanced; and finally the modified acrylic resin is low in surface energy so as to enable the killed microorganisms and other pollutants to be difficultto attach, and the surface of an object is kept smooth and pollution-free. The three components of the capsaicin derivative, the copper ion slow release agent and the modified acrylic resin cooperatewith each other to play a role to achieve efficient and anti-fouling effects of the paint. The paint disclosed by the invention is remarkable in antifouling effect and low in addition amount of anti-fouling effective components, and is environment-friendly antifouling paint.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antifouling coating and a preparation method thereof. Background technique [0002] Marine biofouling refers to the damage to objects caused by marine organisms attached to the surface of objects such as hulls, buoys, and fish cages. Biofouling attached to the surface of the hull will increase the roughness of the hull surface, resulting in increased fuel consumption and increased voyage costs. Among many methods of preventing and controlling marine biofouling, antifouling coating is the most economical and effective method. [0003] According to the type of resin, antifouling paint can be divided into stripping antifouling paint, self-polishing antifouling paint and low surface energy antifouling paint. Non-toxic low surface energy antifouling paint is the development direction of a new generation of antifouling paint, but its application is limited due to its high cost, p...
