Problems solved by technology

Since the ship is immersed in seawater all the year round, it is severely corroded by seawater. In addition, the steel structure of the ship will burst and peel off due to thermal expansion and contraction. Therefore, we urgently need a maintenance coating for ships to solve this problem.

Abstract

The invention discloses a ship maintenance paint. Each portion of the ship maintenance paint is composed of, by mass, 25 to 35 parts of butyl acrylate, 20 to 30 parts of epoxy resin, 15 to 25 parts ofpolyacrylic acid vinyl ester emulsion, 10 to 20 parts of mica powder, 10 to 20 parts of an anti-rust paint, 20 to 25 parts of an anti-corrosive filling material, 20 to 30 parts of deionized water, and 10 to 20 parts of an auxiliary agent. The ship maintenance paint possesses excellent anti-corrosive effect, and obvious anti-shedding effect, is excellent in comprehensive performance, is capable ofprolonging ship service life; the preparation conditions are mild; the preparation method is simple; operation is easy; and certain popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a maintenance coating for ships. Background technique [0002] Marine coatings are a general term for coatings used in various parts of ships and marine engineering structures to meet the special requirements of preventing seawater, marine atmospheric corrosion, marine organisms, and other special requirements. Marine maintenance coatings need to have good adhesion, good water resistance, chemical resistance and abrasion resistance, and excellent performance. Ship anti-corrosion paint can be used under harsh conditions and has a long-term anti-corrosion life. Fuxi anti-corrosion paint can generally be used for 10 or 15 years in chemical atmospheres and marine environments, even in acid, alkali, salt and solvent media , and under certain temperature conditions, it can also be used for more than 5 years. Since the ship is immersed in seawater all the year round, it is severely c...
