Abstract

The invention provides water-based anticorrosive paint for a metal matrix and the application of the water-based anticorrosive paint, and belongs to the technical field of paint. The coating comprisesthe following components in parts by weight: 10-69 parts of waterborne epoxy resin, 5-69 parts of a fluorosilicone emulsion, 3-20 parts of a solid filler, 5-44 parts of a diluent, 2-20 parts of a curing agent and 1-7 parts of a coalescing agent. After the water-based anticorrosive paint forms a film, due to the existence of the fluorine-silicon emulsion, the film can efficiently generate electricity through friction in the presence of waves, generated charges are loaded on the surface of the film and induct a metal matrix, and the situation that the metal matrix loses electrons and is corroded is prevented; meanwhile, the solid filler and the water-borne epoxy resin are used, so that the coating film has certain corrosion resistance.

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...
