The invention discloses a special anticorrosive paint for an electric iron tower and a preparation method of the special anticorrosive paint and belongs to the technical field of electric power anticorrosive materials. The paint is prepared from components in parts by weight as follows: 30-44 parts of epoxy resin, 2-5 parts of polymethyl acrylate, 5-10 parts of chloroform, 3.8-5.5 parts of a coupling agent, 12-17 parts of nano-oxide, 4.5-5.6 parts of polydiallyl dimethyl ammonium chloride, 2.8-3.3 parts of tributyl phosphate, 6.7-7.2 parts of a water repellent, 5.8-6.3 parts of a heat resistant agent, 8.9-9.6 parts of an anti-corrosive reagent, 7.3-8.8 parts of a corrosion inhibitor, 20-26 parts of acetone and 46-55 parts of water. The anticorrosive paint prepared with the method has the advantages of being excellent in mechanical performance and insulating performance, resistant to water, high and low temperature and chemical corrosion, high in adhesive force, capable of maintaining stability in acid-base environments and excellent in comprehensive performance. The coating can form a layer of compact protective film on the surface of the iron tower and achieve an anti-rust effectwhile preventing corrosion, and the service life of the electric iron tower is prolonged.
