▎ 摘  要

NOVELTY - Graphene modified anti-corrosion coating comprises a first component and a second component whose mass ratio is 1:0.1-0.2, where the first component includes 100 pts. wt. epoxy resin, 2-4 pts. wt. reduced graphene oxide modified by silane coupling agent, 4-5 pts. wt. nano-ceramic powder, 0.1-0.5 pts. wt. defoamer and 0.5-1 pts. wt. leveling agent. The second component includes 100-150 pts. wt. amine curing agent, 1-5 pts. wt. defoamer and 5-10 pts. wt. leveling agent. USE - Graphene modified anti-corrosion coating used in the field of metal anticorrosion (claimed) and to bridge, ship, work field device and industrial mass production. ADVANTAGE - The graphene modified anti-corrosion coating reduces agglomeration phenomenon in the film-forming carrier, promotes the uniform distribution, prolongs the water and oxygen molecule corrosion factor and the protected base body of the contact path, and improves the corrosion resistance of the coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a graphene modified anticorrosion coating, which involves: a. dispersing the graphene oxide slurry into the silane coupling agent, adding DCC and ultrasonically disperse for 20-40 minutes, then placing in a water bath at 55-65℃ and stirring for 5-7 hours to obtain silane coupling agent modified graphene oxide; b. adding the silane coupling agent-modified graphene oxide to the dimethyl formamide solvent under ultrasonic conditions, adding ammonia water to disperse evenly, adding vitamin C to adjust the pH to 6-7, heating at 75-95℃, carrying out reduction reaction for 4-6 hours under low temperature, washing with pure water and drying under vacuum to obtain a reduced graphene oxide modified by the silane coupling agent; c. uniformly mixing the reduced graphene oxide modified by the above-mentioned silane coupling agent, epoxy resin, nano-ceramic powder, defoamer and leveling agent to obtain first component; and d. mixing the amine curing agent, defoamer and leveling agent to obtain a product.
