Abstract

The invention discloses anticorrosive paint for ship surface which is prepared from the following raw materials in parts by weight: 25-38 parts of film-forming substance, 20-30 parts of polyaniline modified mica iron oxide, 2-9 parts of polyethylene glycol, 9-15 parts of antirust emulsion, 4-10 parts of dispersing agent, 6-11 parts of cellulose, 1-3 parts of diluent, 6-11 parts of ground limestone and 3-8 parts of epoxy acrylate. The anticorrosive paint for ship surface has the beneficial effects that the paint is good in anticorrosive property, can be used in an acid and alkali resistant environment and has a good effect of protecting the ship surface.

Description

technical field [0001] The invention relates to an anti-corrosion coating for the surface of a ship hull. Background technique [0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. Now due to the development of the ocean-going industry, the shipbuilding industry is also developing rapidly, and there are more and more large ships. Due to the high corrosiveness of seawater, it will corrode the hull and reduce the service life, so a kind of anti-corrosion coating for ships is needed. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical...
