Marine anti-fouling coating

Abstract

The invention discloses a marine anti-fouling coating. Raw materials of the coating comprise, by weight, 20-35 parts of a polydimethylsiloxane elastomer, 40-60 parts of zinc acrylate resin, 10-25 parts of teflon, 3-10 parts of a vinylidene difluoride-hexafluoropropylene copolymer, 1-5 parts of nanometer acicular structured manganese vanadate, 10-25 parts of carbon nanotube, 5-10 parts of silicon nitride, 1-5 parts of nano-silica, 3-10 parts of nano-zinc oxide, 2-8 parts of montmorillonite, 3-10 parts of fiber fluff, 2-10 parts of paprika, 1-5 parts of ground pepper, 0.5-2 parts of PTPB, 0.2-1.5 parts of 4,5-dichloro-2-n-octyl-3-isothiazolinone, 10-30 parts of ethanol, 2-10 parts of butyl cellosolve, 5-10 parts of water, 1-3 parts of a silane coupling agent and 2-5 parts of an auxiliary agent. The marine anti-fouling coating provided by the invention has high strength, good antifouling effect and excellent durability.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special 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 ships and marine stru...

AI Technical Summary

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 have poor antifouling properties, strength and durability, and tend to lose their performance during use, which limits their application.
