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 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. Applications of halogenated indoles and their derivatives as marine antifouling agents. One or more of the halogenated indole and halogenated indole derivatives are used as marine antifouling agents. The halogenated indole compounds of the invention can inhibit the attachment of marine fouling microorganisms, marine algae and large marine fouling animals, and exhibit high-efficiency and broad-spectrum antifouling activity. Halogenated indole compounds widely exist in marine organisms, are easy to be biodegraded, have low toxicity and no pollution, and marine antifouling agents prepared from them do not contain heavy metals and will not cause harm to the environment. At the same time, the artificial synthesis method of halogenated indole compounds is simple, which is conducive to their application in marine antifouling coatings.

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...
