However, the ensuing problem is that the hulls of these large and small ships are all coated with anti-corrosion coatings and anti-fouling coatings that contain harmful substances such as various poisons and heavy metal compounds.
Coatings will release organic solvents during construction, use and curing, which pose a serious threat to the environment and human health

Abstract
The invention discloses a high-efficiency ocean anticorrosive paint, which comprises the following active ingredients in parts by weight: 25-40 parts of fluorinated acrylate, 18-33 parts of silicone rubber, 3-10 parts of antirust pigment, 10-25 parts of filler, 0.1-1 part of chelating agent, 0.1-1 part of dispersing agent, and 0.1-1 part of wetting agent. According to the high-efficiency ocean anticorrosive paint, the silicone rubber and fluorinated acrylate materials have extremely low surface free energy, low friction coefficient, high hydrophobicity and high contamination releasing characteristic, so that the pollution and corrosion coefficients of steel can be lowered; the antirust pigment and filler are nanoscale particles, the nanoparticles and coatings form stronger hydrogen bonding, the compactness and ion permeability resistance of the coatings can be enhanced; through the nanoparticles, the rheological property of the paint can also be improved, and the adhesion force, hardness, finish degree and anti-aging properties of the coatings can be improved.
Description
technical field [0001] The invention relates to an anti-corrosion coating, in particular to a high-efficiency marine anti-corrosion coating, which belongs to the technical field of coatings. Background technique [0002] Seawater is the largest and highly corrosive natural electrolyte in nature. Seawater contains almost all chemical elements on the earth, and its composition is very complex. In addition, seawater also contains dissolved oxygen, marine life and decaying organic matter. These substances have caused great harm to metal components such as various marine transportation tools, oil production platforms, and marine equipment. With the development of coastal transportation, industrial production, and national defense construction in various countries, the threat of seawater and marine atmospheric corrosion has also become more and more serious. The more prominent, the more applicable and economical marine engineering protection method is to apply marine coatings tha...
