Problems solved by technology

This type of compound has a certain inhibitory effect on the attachment of marine fouling organisms, but the effect is not yet comparable to that of organotin compounds. At the same time, the artificially synthesized compounds have complex structures and low yields, and further research and development of highly efficient and low-toxic compounds is still needed. marine antifouling agent

Embodiment 3

[0034]Example 3 After 3 days of treatment, the blue mytilus was transferred to fresh seawater, and the seawater was replaced every day, the number of silks was counted, and the silk attachment rate was observed. The results showed that after 3 days, when the halogenated indole concentration was less than 10mg / L, the silk of blue mussels could return to the control level, such as figure 1 shown.

[0035] The preparation of embodiment 5 halogenated indole antifouling coatings

[0036] The antifouling paint can be mixed according to the prior art records, and then the antifouling paint obtained by adding the corresponding halogenated indole and its derivatives. The specific composition can be calculated in parts by weight: 25 parts of chlorinated rubber, 10 parts of chlorinated paraffin 6 parts of rosin, 20 parts of xylene, 1 part of additives (dispersant, defoamer, leveling agent, defoamer, anti-settling agent, thickener), 5 parts of talcum powder, 10 parts of red iron oxide ,...

Abstract

The invention specifically relates to application of a halogenated indole and derivatives thereof as a marine antifouling agent, belonging to the technical field of marine antifouling paints. The invention provides application of one or more selected from the group consisting of halogenated indole and derivatives thereof as the marine antifouling agent. According to the invention, the halogenated indole compounds can inhibit attachment of marine stained microbes, marine algae and large-scale marine stained animals and presents high-efficiency and wide-spectrum antifouling activity. The halogenated indole compounds extensively exist in marine organisms, are easy to biodegrade and have low toxicity and no pollution; a marine antifouling agent prepared from the halogenated indole compounds does not contain heavy metals and causes no harm to the environment. Moreover, an artificial synthetic method for the halogenated indole compounds is simple, which facilitates application of the halogenated indole compounds in marine antifouling paints.

Description

technical field [0001] The invention belongs to the technical field of marine antifouling coatings, in particular to the application of a halogenated indole and its derivatives as marine antifouling agents. Background technique [0002] Marine fouling organisms attach to the surface of ships, wharves, and marine cages, causing huge economic losses to marine military, marine transportation, and aquaculture. According to incomplete statistics, the losses caused by biofouling worldwide are about several tens of billions of dollars. [0003] Antifouling coatings are the most effective and economical way to solve biofouling. Traditional antifouling coatings mainly achieve antifouling effects by slowly releasing heavy metals such as copper, tin, mercury, and lead. However, this type of antifouling agent seriously pollutes the coast and has certain safety for marine ecology and human food and health. Hidden danger. In particular, organotin compounds are highly toxic and difficul...
