The invention discloses antifouling modified asphalt paint. The paint is characterized by being prepared from the following raw materials in parts by weight: 13-16 parts of E-12 epoxy resin, 4-6 parts of benzidine, 1-2 parts of melamine, 2-3 parts of borax, 0.4-0.8 part of zinc pyrithione, 0.3-0.6 part of sodium dichloroisocyanurate, 0.5-1.0 part of 1,3-dibromo-5,5-dimethylhydantoin, 2-4 parts of bois de rose oil, 2-3 parts of nano fluorocarbon, 1-3 parts of methylenedithiocyanate, 1-3 parts of 2-mercaptopyridine zinc oxide, 1-3 parts of bamboo fiber, 2-3 parts of dimethicone, 2-3 parts of versatate-acrylate emulsion, 2-3 parts of white carbon black, 1-2 parts of vermiculite powder, 0.5-1.0 part of octadecanol polyoxyethylene ether, 32-38 parts of modified asphalt, 6-9 parts of modified waste resin sand, 11-13 parts of xylene, 8-11 parts of diphenyl ether and 3-5 parts of tannin. The paint adopts mutually synergetic effect of non-toxic aqueous biocide zinc pyrithione, sodium dichloroisocyanurate and 1,3-dibromo-5,5-dimethylhydantoin, is capable of effectively preventing attachment of marine organisms from polluting a water body, has weather resistance, heat resistance, low-temperature resistance and chemical drug resistance by adding nano fluorocarbon, has unique non-adhesive property and low friction, and has the effects of reducing environment pollution, improving antifouling property and anti-aging property of a paint film by adding the modified waste resin sand.
