Problems solved by technology

Marine biofouling will increase the navigation resistance of ships, lead to accelerated metal corrosion, block seawater pipelines, reduce the service life of marine equipment, and affect the aquaculture industry, etc.
So far, coating antifouling coatings is still the most economical and effective measure to prevent marine organisms from adhering. Antifouling coatings can keep the immersed parts smooth and free of dirt. At present, they are mainly used in ships and marine structures in seawater and freshwater. However, the current antifouling coatings are not good in antifouling, strength, durability and environmental protection. In the process of use, they are easy to lose their performance, which limits their application.

Abstract

The invention discloses a marine low-surface-energy anti-fouling coating. Raw materials of the coating comprise modified silicone-acrylate resin, chlorosulfonated polyethylene, teflon, a vinylidene fluoride-hexafluoropropene copolymer, epoxy resin, waterborne polyamide, zinc phosphate, carbon nanotube, silicon nitride, nano-sized iron oxide, nano-zinc oxide, mica powder, cerium stearate, fiber fluff, paprika, ground pepper, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, PTPB, 4,5-dichloro-2-n-octyl-3-isothiazolinone, xylene, ethyl acetate, acetone, ethylene glycol monobutyl ether, cyclohexanone and an auxiliary agent. The marine low-surface-energy anti-fouling coating brought forward in the invention has high strength and a good antifouling effect, is resistant to seawater corrosion when in use and is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special low surface energy antifouling coating for ships. Background technique [0002] There are a large number of microorganisms, marine plants and marine animals in the ocean, which will adsorb on the metal surface and grow and reproduce on the metal surface. Since human beings engaged in marine activities, the problem of marine biofouling has been a major problem that has restricted the development and utilization of marine resources. Marine biofouling will increase the resistance of ships, lead to accelerated metal corrosion, block seawater pipelines, reduce the service life of marine equipment, and affect the aquaculture industry. So far, coating antifouling coatings is still the most economical and effective measure to prevent marine organisms from adhering. Antifouling coatings can keep the immersed parts smooth and free of dirt. At present, they are mainly used in sh...
