Capsaicin antifouling paint

Abstract

Capsaicine antifouling paint is characterized by comprising the following components in parts by mass: 16-31 parts of a binder, 4-8 parts of a plasticizer, 23-42 parts of pigment and filler, 1-10 parts of capsaicine, 2-4 parts of an anti-settling agent and 11-20 parts of a solvent. Compared with the prior art, capsaicine is extracted from natural capsicum annuum as an antifouling agent, so that the capsaicine antifouling coating is not influenced by temperature, and has good functions of resisting bacteria and expelling marine attached organisms. Compared with other chemical coating additives,the capsaicine antifouling coating does not poison attached organisms to cause biological variation, and does not destroy a marine food chain or cause seawater body pollution. In addition, the capsaicine antifouling paint is good in storage stability and has good matching performance with other antirust paints and the like.

Description

technical field [0001] The invention belongs to the technical field of biological prevention and control of marine fouling, and in particular relates to a capsaicin antifouling paint. Background technique [0002] There are as many as 4,500 species of marine organisms in the ocean. Among them, marine fouling organisms, also known as marine epiphytes, are the general term for animals, plants and microorganisms that grow on the bottom of ships and on the surface of other facilities in the sea. There are many kinds of marine attached organisms, among which the more harmful and common ones are barnacles, oysters, sea squirts, seaweeds, etc. They can attach to solid surfaces in seawater for growth and reproduction, especially in the oxygen and sunny surface seawater interval. Since the bottom part of the ship has been soaked in seawater for a long time, it is seriously fouled by marine organisms. These organisms will increase the weight and navigation resistance of the ship, and ...

AI Technical Summary

Problems solved by technology

Traditional antifouling coatings generally use organic toxic materials such as organic tributyltin (TBT) and dichlorodiphenyltrichloroethane (DDT). Among them, coatings containing organic tin antifouling agents are the most effective and widely used, but research It was found that organic tin antifouling agents have a certain solubility in the sea, which will cause damage to marine materials and the marine environment, and seriously threaten the survival of other marine organisms. Therefore, in 2008, the International Maritime Convention Organization (IMO) proposed to stop the use of organic tin (TBT) antifouling agents globally. ) antifouling coatings; DDT has efficient insecticidal function, and was widely used in my country in the 1960s and 1980s. However, due to its neurotoxicity and liver toxicity, it is extremely harmful to humans and the environment. In 1983, my country began to restrict the use of DDT production and use
