Problems solved by technology

At present, the research on natural antifouling agents is still in the basic theoretical stage, and there is still a considerable distance from practical application.
The artificially synthesized non-toxic antifouling agents need to be used in conjunction with a large amount of cuprous oxide to have a better comprehensive effect; however, the extensive use of cuprous oxide antifouling agents has caused a large amount of deposition of copper compounds in harbors. It has had a serious impact on the water quality of the harbor and the marine biological environment

Abstract

The invention provides a marine antifouling coating. The coating comprises a film forming substance, an antifouling agent and a dilute serving as raw material components, wherein the film forming substance is organic silicon modified acrylic resin; and the antifouling agent comprises nano silver, zinc oxide and a pyrithione coordination compound. An environmentally-friendly marine antifouling coating is prepared by taking the organic silicon modified acrylic resin as the film forming substance, a silane coupling agent and polyamide as curing agents and the nano silver, the zinc oxide and the pyrithione coordination compound as composite disinfection anti-alga agents. The organic silicon modified acrylic resin has low surface energy, so that ordinary microorganisms are difficult to be attached to the surface of the resin; simultaneously, the nano silver and the pyrithione coordination compound have good disinfection and bacteriostasis effects and can effectively prevent the adhesion of marine microorganisms. Moreover, the coating provided by the invention does not contain the conventional cuprous oxide and organic tin antifouling agent, so that the environment is protected well.

Description

technical field [0001] The invention relates to a marine antifouling paint and a preparation method thereof. Background technique [0002] Marine fouling organisms, also known as marine fouling organisms, are a general term for organisms that grow on the bottom of ships and on the surface of all facilities in the sea. There are more than 2,000 known fouling organisms, including animals, plants and microorganisms. There are more than 600 kinds of fouling organisms along the coast of my country, among which the main fouling organisms are barnacles, bryozoans, polyps, mollusks, ship borers, and seaweeds. Due to the different global marine environmental conditions, marine biofouling reflects the characteristics of different types and attachments of fouling organisms due to different regions and seasons. Because of the diversity and complexity of marine fouling organisms, the prevention and control of marine fouling has become a worldwide problem and a research hotspot. [000...
