NOVELTY - A coating comprises primer comprising 30-35 pts. wt. epoxy resin, 12-15 pts. wt. n-butyl titanate, 8-10 pts. wt. acetylacetone chromium, 8-10 pts. wt. polyvinyl formal and 90-100 pts. wt. zinc powder, and topcoat comprising 65-70 pts. wt. tetrafluoroethylene, 20-25 pts. wt. graphene oxide, 12-15 pts. wt. styrene, 3-5 pts. wt. acrylic acid, 12-15 pts. wt. methyl isobutyl ketone, 0.8-1.0 pts. wt. azobisisobutyronitrile and 0.5-0.6 pts. wt. dibutyltin dilaurate. USE - Coating used for steel structures. ADVANTAGE - The coating comprises primer having excellent adhesive property to the steel components of the transmission tower, excellent electrochemical or chemical corrosion resistance, durability, improved weather resistance and corrosion resistance of the coating, short curing time, and is resistant to damage by UV rays and excellent adaptability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of coating, which involves preparing primer by (a) adding n-butanol to chromium acetylacetonate, dripping n-butyl titanate under stirring, adding mercaptopropyltriethoxysilane, stirring uniformly, adding to the reaction kettle, reacting to obtain mixed solution, (b) heating the epoxy resin to 100-120 degrees C, slowly adding the mixed solution, stirring for 1-2 hours to obtain the modified epoxy resin, (c) mixing the modified epoxy resin, polybutene formal, zinc powder and the mixed liquid uniformly, preparing topcoat by (d) evacuating the polymerization reactor with nitrogen, mixing styrene and acrylic acid, adding azobisisobutyronitrile and dibutyltin dilaurate under stirring conditions, stirring to uniformly mix the solution, (e) sucking the methyl isobutyl ketone into the reaction kettle under vacuum, raising the temperature to 70 degrees C, adding the mixed solution to the reaction kettle, stirring, adding tetrafluoroethylene monomer into the reaction kettle, reacting, cooling to room temperature, adding graphene oxide and stirring uniformly.
