Abstract

The invention provides a technology capable of preventing marine organisms from adhering on seagoing vessels, undersea structures, fishing devices and the like for a long time, and in particular relates to an environment-safe anti-fouling paint capable of preventing large-sized marine organisms from adhering. The anti-fouling paint is coated on the seagoing vessels, the undersea structures, the fishing device and the like, and comprises the components in percentage by weight: 1-50% of antimicrobial composition, 0.1-50% of copper and or inorganic copper compound, 10-85% of siloxane-acrylic resin (the content of siloxane is 3-15wt%) and 1-70% of rosin metal salt and / or rosin derivative metal salt, wherein the antimicrobial composition contains a nitrile antimicrobial agent, a pyridyl antimicrobial agent, a haloalkylthio antimicrobial agent, an organic iodo antimicrobial agent, a thiazyl antimicrobial agent and a benzimidazolyl antimicrobial agent.

Description

technical field [0001] The present invention relates to antifouling coatings for preventing the attachment of marine organisms such as shellfish and seaweed to articles that are used for long periods under the sea surface such as seagoing vessels, subsurface structures and fishing gear. Background technique [0002] Because sea vessels, subsurface structures, fishing gear, etc. are used under the sea surface for a long time, they will attach marine organisms, such as seaweeds, barnacles, snails, bryozoans, and molluscs. Therefore, their maintenance requires a lot of manpower and high costs. [0003] To prevent corrosion of underwater structures and reduction in speed of seagoing vessels caused by these marine organisms, and to prevent the death of aquatic products due to the attachment of marine organisms to fishing gear such as fishing nets and wire mesh for fish farming , usually using antifouling paints containing organotin compounds. [0004] However, organotin compoun...
