The invention discloses an ocean heavy anti-
corrosion epoxy aluminum-rich nano-
coating, which is composed of components A and B with a
mass ratio of 18:1 and comprises the following components in parts by
mass: 14-18 parts of
epoxy resin, 3-6 parts of hydroxyl
acrylic resin, 125-145 parts of nano-aluminum
powder, 3-6 parts of talcum
powder, 2-4 parts of
barium sulfate, 3-5 parts of an anti-
settling auxiliary agent, 1-2 parts of a dispersing auxiliary agent, and 10-13 parts of a
solvent, wherein the component B comprises the following components with contents in parts by
mass: 50-60 parts of a curing agent and 40-50 parts of a
solvent. The invention also discloses a preparation method of the
coating. By adopting the scheme of the invention, the nano-aluminum
powder content in a
lacquer film is high, the cost is low, the process is simple, and no special equipment is needed. According to the invention, the prepared
coating has
strong binding force with a matrix, also has relatively good
binding force with various other additional coatings, is excellent in
corrosion-resistant performance in an ocean atmospheric environment, and long in service life, and is a heavy anti-
corrosion coating applicable to iron and steel constructions such as a drilling platform and a bridge in an ocean atmospheric environment.
