NOVELTY - Anticorrosive coating comprises silane modified epoxy resin pre-polymer mixture, curing agent, anti-corrosion filler, photo-thermal filler and organic solvent according to the mass ratio of 100:(5-20):(1-40):(1-40):(20-120). USE - The coating is useful in the inner wall of pipeline (claimed). ADVANTAGE - The coating: utilizes the built-in optical fiber technology, when the coating on the inner wall of the pipeline is damaged; and achieves the rapid maintenance of the coating through the photothermal effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the anticorrosive coating, comprising (i) successively uniformly dispersing the anticorrosive filler and the photo-thermal filler in the organic solvent, adding to the silane-modified epoxy resin prepolymer mixture and uniformly dispersing, and (ii) adding the curing agent to the mixed solution obtained in the step (i), adding organic solvent to help it completely dissolve, and quickly maintaining; and (2) use of the anticorrosive coating in the inner wall of pipeline, comprising using spraying device to evenly spray the anti-corrosion coating to the inner wall of the pipeline, curing, and preparing fast-maintaining anti-corrosion coating on the inner wall of the pipeline.
