Problems solved by technology

However, organotin coatings have good antifouling effects, but also have adverse effects on non-target organisms in the marine environment, endangering the marine environment, and affecting human health through the enrichment process of the food chain
In 2001, the International Maritime Organization (IMO) passed a resolution requiring that starting from January 1, 2008, paints containing organic tin compounds such as TBT should be banned on a global scale; while other products that replace TBT such as copper base paint and It also shows some limitations in practical application, and has toxic effects on oysters, algae and various aquatic organisms
However, in practical applications, diketopiperazine compounds such as cyclic (proline-alanine) need to be used in combination with coating base materials, otherwise they will be lost with seawater and cannot function
But, existing paint base material raw material is numerous, and base material type, proportioning, effective dosage etc. all can exert influence on the performance of control effect, therefore, it is necessary to seek a kind of suitable coating system, to play ring (proline) Acid-alanine) and other diketopiperazine compounds to achieve efficient, broad-spectrum, environmentally friendly, non-toxic prevention and control of marine organisms for marine artificial facilities such as ships

Abstract

The invention belongs to the technical field of coatings, and particularly discloses a marine biocontrol coating and a preparation method thereof. The coating is prepared from, by weight, 70-80 parts of chlorinated rubber, 45-60 parts of rosin, 100-120 parts of diketopiperazine compounds, 50-70 parts of zineb, 160-180 parts of iron oxide red, 280-320 parts of zinc oxide, 1-10 parts of barium carbonate, 1-5 parts of magnesium oxide, 50-60 parts of tricresyl phosphate, 5-15 parts of organic bentonite and 140-160 parts of solvent. The coating has high adhesion and is excellent in antifouling property, long in antifouling period, capable of effectively preventing and killing off marine fouling organisms such as barnacles, mussels and algae, efficient, poisonless and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a marine biological control coating and a preparation method thereof. Background technique [0002] Marine fouling organisms refer to the general term for animals, plants and microorganisms that adhere to or inhabit the surface of ships and various underwater objects in the marine environment and have adverse effects on human activities. They are one of the important factors affecting the safety and service life of marine facilities. First, it is also a difficult problem encountered by human beings when they started to engage in maritime activities, and its occurrence process is completely a natural phenomenon. [0003] my country has a long coastline, and the ocean environment is complex from south to north. A large number of ships sail in the harsh ocean environment. The bottom part of the ship has been soaked in seawater for a long time, and it is seriously fouled...
