The invention discloses an anticorrosive tough coating material for an outdoor communication tower, and a preparation method thereof, wherein the anticorrosive tough coating material is prepared fromthe following raw materials by weight: 12-18 parts of a polytrifluorochloroethylene resin, 35-45 parts of a bisphenol A type epoxy resin, 8-12 parts of polyphenylmethylsiloxane, 2-6 parts of alpha,omega-dihydroxy polydimethylsiloxane, 2-6 parts of amino-modified polysiloxane, 2-6 parts of hexamethyldisilazane, 2-6 parts of gas-phase nanometer silicon dioxide, 7-11 parts of silicon carbide short fibers, 12-16 parts of mica iron oxide powder, 2-8 parts of xylene, 10-20 parts of an acetone aqueous solution and 1-3 parts of a polyamine mixed curing agent. According to the invention, the prepared anticorrosive tough coating material has excellent anticorrosive performance, weather resistance and good elasticity; and by coating the communication tower with the anticorrosive tough coating material, the coating is compact, has excellent anticorrosive, anti-aging, hydrophobic, stain-resistant and impact-resistant effects, can well adapt to severe environments, and effectively prolongs the service life of the communication tower.
