Abstract

The invention discloses static anti-fouling self-layering organosilicon coating and a preparation method and application thereof. The coating includes an A component and a B component, wherein the A component includes 50-90 parts of silanol-terminated polydimethylsiloxane, 1-40 parts of a fluorocarbon ester-anti-fouling monomer telomer, 0.1-10 parts of a catalyst, and 0-30 parts of a solvent; theB component is 5-20 parts of silicate ester; the fluorocarbon ester-anti-fouling monomer telomer is prepared from (meth)acrylate fluorocarbon ester, a (meth)acrylate anti-fouling monomer, a mercapto silane coupling agent, an initiator and a solvent. The coating can form self-layering coatings with anti-fouling functional groups being enriched on surfaces of the coatings, thus endowing a material with excellent fouling resistance. Through the organosilicon, the coating has good decontamination ability. The self-layering material can meet anti-fouling requirements of ships with low speeds, offshore oil platforms and other facilities, and has excellent drag reduction performance.

Description

technical field

[0001] The invention belongs to the technical field of marine antifouling materials, and in particular relates to a static antifouling self-layering organic silicon coating and a preparation method and application thereof. Background technique

[0002] In recent years, developing marine resources and developing marine economy has become an important strategy of many countries. However, the problem of marine biofouling has brought serious problems to the marine industry and maritime activities. It refers to the biofouling formed by marine animals, plants and microorganisms attached to the surface submerged in seawater, which will increase the resistance of ships and increase fuel consumption. , accelerated metal corrosion and other consequences. At present, the application of self-polishing marine antifouling coatings is the most commercial antifouling method, but such coatings release a large amount of metal antifouling agents, which have an impact on marine...
