▎ 摘　　要

NOVELTY - Anticorrosive coating for a concrete substrate, comprises 0.1-0.5 pts. wt. modified graphene fine powder, 36-54 pts. wt. fluorocarbon resin, 4-6 pts. wt. silicone resin, 1-2 pts. wt. drier, 1-3 pts. wt. anti-mold and algae agent, and 1-3 pts. wt. leveling agent, wetting and 1-3 pts. wt. dispersing agents, coloring agents, 1.5-3 pts. wt. and 1-3 pts. wt. defoaming agents. The component B comprises 40-60 pts. wt. a polyisocyanate prepolymer; The mass ratio of the component A and the component B is 1:2-4, the modified graphene fine powder is obtained by modifying the graphene fine powder with a silane coupling agent. USE - Anticorrosive coating for a concrete substrate. ADVANTAGE - The anticorrosive coating effectively improves the anticorrosive performance of the coating by modifying the graphene fine powder, the fluorocarbon resin, the silicone resin and the polyisocyanate prepolymer according to a certain proportion, and the comprehensive performance of the anticorrosive coating is excellent, also provides a method for applying the anticorrosive coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for applying an anticorrosive coating for a concrete substrate involves weighing each component according to the composition of component A and component B, after cleaning the surface of the substrate, and mixing component A and component B separately, and then mixing component A and component B according to the mass ratio. It is mixed at a ratio of 1:2-4 to obtain an anticorrosive coating, and the anticorrosive coating is coated on the substrate until it is dried and solidified. The dry film thickness of the anticorrosive coating is 60-80 mu m.
