Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof, high-adhesion and corrosion-resistant coating for ships. Background technique [0002] Ships are exposed to high-salinity marine environment for a long time, and corrosion is extremely serious. Corrosion can not only reduce the strength of the ship’s steel structure, shorten the life of the ship, but also increase the navigation resistance, reduce the speed, and affect the performance and safety of the ship. Corrosion is one of the biggest factors affecting its life. Corrosion damage or fracture not only causes the leakage of harmful substances, pollutes the environment, but sometimes also causes sudden catastrophic accidents, endangering human safety. For ships, anti-corrosion and anti-rust is always a global problem that plagues people. The current marine paint coating film is not dense enough, waterproof and anti-permeability, anti-corrosion performance is not good...
