Anti-corrosion and anti-fouling coating material as well as preparation method and application thereof

The invention relates to the field of marine anti-corrosion and anti-fouling coating materials, and discloses an anti-corrosion and anti-fouling coating material as well as a preparation method and application thereof. The coating comprises the following raw materials in parts by mass: 3-4 parts of nano silicon dioxide, 20-30 parts of epoxy resin, 20-30 parts of a curing agent, 10-25 parts of organic silicon resin, 4-6 parts of cerium salt, 12-14 parts of seaweed gel, 6-12 parts of phosphate, 1-3 parts of a dispersant, 1-3 parts of a stabilizer, 5-10 parts of a bactericide, 1-3 parts of an auxiliary agent and 60-100 parts of a solvent. The epoxy resin is bisphenol A epoxy resin; the curing agent is an amino silane curing agent. According to the anti-corrosion and anti-fouling coating material provided by the invention, the compatibility among the raw materials is good. Through the synergistic effect of various raw materials, the adhesion of the coating on a base material and excellent corrosion resistance and
