Abstract

The invention provides a water-based anti-corrosion coating for metal substrates and an application thereof, belonging to the technical field of coatings. The components include the following parts by weight: 10-69 parts of water-based epoxy resin, 5-69 parts of fluorosilicone emulsion, 3-20 parts of solid filler, 5-44 parts of diluent, 2-20 parts of curing agent, film-forming assistant 1 to 7 doses. After the water-based anti-corrosion coating of the present invention is formed into a film, due to the existence of the fluorosilicon emulsion, the coating film can efficiently triboelectrically generate electricity in the presence of waves, and the generated charges are loaded on the surface of the coating film and sensed on the metal substrate. To prevent the metal matrix from being corroded due to electron loss; at the same time, the use of solid fillers and water-based epoxy resin also makes the coating film have a certain anti-corrosion performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based anti-corrosion coating for metal substrates and its application. Background technique [0002] Metal anti-corrosion protection is one of the important protection contents of equipment used in water environment, and it is of great significance to the long-term stable operation of equipment in water. Anti-corrosion coatings are one of the most commonly used methods of corrosion protection. With the increasingly higher requirements for environmental protection, water-based anti-corrosion coatings have become the development trend of anti-corrosion protection. [0003] With the development of economy, China is facing more and more energy pressure. Research on the effective use of various renewable and clean energy sources to achieve sustainable energy development is of great significance to my country's economic development, social stability, and even national defens...
