Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a marine anticorrosion coating. Background technique [0002] Marine anti-corrosion is one of the key technologies in marine engineering. Stress corrosion cracking, hydrogen embrittlement, corrosion fatigue, and intergranular corrosion caused by metal corrosion in the ocean will cause sudden fracture of marine engineering steel structures, leading to ecological disasters in the marine environment and causing huge loss. In recent years, more and more attention has been paid to marine corrosion and protection at home and abroad. Various seawater corrosion-resistant materials have been introduced continuously, and various anti-corrosion construction technologies have also made great progress, but they are still far from meeting actual needs. [0003] Marine anti-corrosion coatings refer to anti-corrosion coatings used in marine environments, which generally require the following p...
