Abstract

The invention relates to a corrosion-resistant coating material for navigation marks and a preparation method of the material. The raw materials of the coating material comprise the following components in parts by weight: 24-32 parts of epoxy resin, 14-22 parts of polyester, 1-3 parts of titanate coupling agents, 6-15 parts of graphene, 10-20 parts of zinc powder, 35-45 parts of siloxane oligomers and 4-12 parts of antimicrobial agents. The preparation method is simple to operate, and graphene and zinc powder are evenly dispersed in a mixture; the coating material solves the problems that a coating film of the coating material for the navigation marks is not dense enough, the waterproof and permeability resistance is poor, the anticorrosion performance is poor, and the adhesion force is poor in the prior art; and through the synergistic effect of all components, the corrosion resistance, the friction resistance, the water resistance, the weather resistance and the impact resistance ofthe coating are improved in the seawater environment , and meanwhile, the service life of the navigation marks is prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a corrosion-resistant coating used for navigation aids and a preparation method thereof. Background technique [0002] The marine environment is a complex corrosive environment. In this environment, seawater itself is a strong corrosive medium. At the same time, waves, waves, tides, and currents produce low-frequency reciprocating stress and impact on the navigation mark. Corrosion is extremely serious in the high-temperature marine environment. Corrosion not only reduces the structural strength of the buoy, shortens the service life, but also attaches marine organisms to its surface. Marine microorganisms, attached organisms and their metabolites all have a direct impact on the corrosion process. or indirect acceleration. [0003] Existing coatings are still difficult to deal with the problems of seawater corrosion, sudden changes in marine climate, and marine organisms. At pr...
