Abstract

The invention belongs to a single-component primer-topcoat ship corrosion and pollution prevention coating which is prepared from, by weight, 50-60 parts of modified epoxy resin, 20-25 parts of silicon resin, 15-20 parts of polyester resin, 16-20 parts of phenolic curing agents, 10-15 parts of polyacrylate leveling agents, 3-5 parts of wetting agents, 10-15 parts of titanium dioxide, 0.5-1.5 partsof 2-methylimidazole, 0.5-1.5 parts of benzoin, 3-5 parts of graphene, 4-8 parts of isothiazolinone, 20-25 parts of cuprous oxide, 4-8 parts of sterilizing agents, 2-4 parts of n-zinc oxide, 20-25 parts of n-ferrite and 15-20 parts of wollastonite powder. The coating has high adhesive force and high salt water and salt fog corrosion resistance and is good in weather resistance and high and low temperature resistance, and the coating serves as a corrosion and pollution prevention coating of a ship armor.

Description

technical field [0001] The invention belongs to the technical field of coatings for ships, and in particular relates to a single-component, bottom-surface-integrated anti-corrosion and anti-fouling coating for ships. Background technique [0002] With the rapid development of our country's strength, the continuous realization of the dream of a strong country, the establishment of a powerful navy and ocean freight fleet and the continuous development of marine projects, the requirements for anti-corrosion and anti-fouling will become higher and higher, and the development of high-performance and high-quality marine It is imminent to apply anti-corrosion and anti-fouling materials. Ships sail at sea for a long time, and a large amount of algae and harmful substances attach and grow, which directly affects the speed of the ship and corrodes the surface of the ship, seriously affecting the use effect. Contents of the invention [0003] In order to solve the technical problems...
