Deep sea anticorrosive coating and preparation method thereof

The invention belongs to the technical field of coatings, and particularly relates to a deep sea anticorrosive coating and a preparation method thereof. The deep sea anticorrosive coating comprises a main agent and a curing agent in a mass ratio of (3-6): 1, wherein the main agent comprises the following raw material components in parts by weight: 30-50 parts of epoxy resin, 0.2-1 part of carbon nanotubes, 5-10 parts of a first reactive diluent, 0.2-3 parts of a first auxiliary agent, 5-10 parts of a first organic solvent, 2-20 parts of toner, 20-55 parts of composite filler and 0.5-2 parts of a thixotropic agent; and the curing agent comprises the following raw material components in parts by weight: 50-85 parts of amine resin, 10-20 parts of a second reactive diluent, 2-6 parts of a second auxiliary agent and 2-25 parts of a second organic solvent. The deep sea anticorrosive coating has the advantages of high solid content, low VOC content, good adhesive force, excellent recoatability, no influence on the a
