Marine coating capable of effectively preventing marine organism adhesion and preparation method thereof

Abstract

The invention provides a marine coating capable of effectively preventing marine organism adhesion and a preparation method thereof, and relates to the field of marine coatings. The coating comprisesa component A and a component B. The component A comprises the following components in parts by weight: 30-50 parts of dimer acid modified epoxy resin, 10-20 parts of fluorosilicone resin, 5-12 partsof hydroxyl carbon nano tubes, 4-8 parts of polydimethylsiloxane, 15-20 parts of tourmaline, 5-10 parts of functionalized graphene, 2-5 parts of bentonite, 1-2 parts of tributyl phosphate, 1-1.5 partsof capsaicin, 0.5-3 parts of a composite bactericidal component, 3-7 parts of liquid polysulfide rubber, 5-10 parts of hyperbranched polyether, 0.1-0.5 parts of methyldiethanolamine, 0.1-0.5 parts ofdioctyl phthalate, 1-3 parts of hydrogen-terminated silicone oil, 5-10 parts of butyl acetate and 20-40 parts of xylene. The component B is a polyamide curing agent. The marine coating has excellentproperties and high mechanical strength and can effectively protect a ship body from seawater corrosion, and seawater hanging plate experimental verification shows that the coating can effectively prevent marine organism adhesion.

Description

technical field [0001] The invention relates to the field of marine coatings, in particular to a marine coating that can effectively prevent marine organisms from adhering and a preparation method thereof. Background technique [0002] Marine coatings are a general term for coatings used in various parts of ships and marine engineering structures to meet the special requirements of preventing seawater, marine atmospheric corrosion, marine organisms, and other special requirements. There are more than 8,000 kinds of plants and 59,000 kinds of marine animals in the seas of the world, among which there are more than 600 kinds of attached plants and more than 18,000 kinds of attached animals. The larvae or robes of these periphytons can float or swim, and after a certain stage of development, they attach, settle and further reproduce on the bottom of ships, underwater structures or rocks on the shore. When a large number of these marine organisms attach to the bottom of the shi...

AI Technical Summary

Problems solved by technology

When a large number of these marine organisms attach to the bottom of the ship, it will cause great harm to the ship. They will not only increase the weight of the ship and reduce the load of the ship, but will also greatly increase the resistance of the ship's hull, resulting in a reduction in the speed of the ship and fuel consumption. increase
