NOVELTY - Amino-terminated polyether modified graphene oxide aqueous-based high corrosion resistance coating comprises 60-80 pts. wt. aqueous resin, 1-20 pts. wt. silicon dioxide doped graphene oxide modified liquid, 0.1-1 pts. wt. anti-settling agent, 0.05-1 pts. wt. antifoaming agent, 0.05-1 pts. wt. wetting agent, 2-8 pts. wt. aqueous cross-linking agent, 0.1-0.5 pts. wt. catalyst, 4-10 pts. wt. cosolvent, 0.1-1 pts. wt. flatting agent, 0.5-3 pts. wt. thickening agent and 1-10 pts. wt. de-ionized water. USE - Used as amino-terminated polyether modified graphene oxide aqueous-based high corrosion resistance coating. ADVANTAGE - The coating reduces the hydrophilicity of its surface and increases its dispersibility and mixing into the coating can increase the corrosion resistance and weather resistance of the coating. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the coating, comprising (i) adding 0.1-20% graphene oxide solution into an amino-terminated polyethylene glycol with a degree of polymerization of 10-100, where the mass ratio of the amino-terminated polyethylene glycol and the graphene oxide solution is 0.005-1, and stirring at 75 degrees C for 1-24 hours to obtain a graphene oxide modified solution, (ii) adding gas phase silicon dioxide into 95 wt.% ethanol, adding 3-aminopropyltriethoxysilane, where the mass ratio of 3-aminopropyltriethoxysilane and the gas phase silicon dioxide is 0.1-1.5, ultrasonically reacting at 80 degrees C for 0.5-5 hours, filtering with suction, and air-drying at 80 degrees C for 0.5-1 hour to obtain modified silicon dioxide, (iii) adding the modified silicon dioxide into the graphene oxide modification solution, where the mass ratio of the modified silicon dioxide and the graphene oxide modification solution is 0.02-0.5 to obtain silicon dioxide doped graphene oxide modified liquid, and (iv) combining aqueous-based resin, silicon dioxide doped graphene oxide modified liquid, anti-settling agent, antifoaming agent, wetting agent, aqueous-based crosslinking agent, catalyst, co-solvent, leveling agent, thickening agent and deionized water, mixing, stirring at 100-1000 revolutions/minute for 3 hours; and (2) use of high corrosion resistance coating on the surface of the metal to be treated.
