▎ 摘  要

NOVELTY - Graphene and carbon nanotube cold-coated zinc anticorrosive coating comprises 70-85 pts. wt. zinc powder, 3-8 pts. wt. acrylic resin, 0.1-2 pts. wt. modified graphene, 0.2-3 pts. wt. modified hydroxylated carbon nanotubes, 0.1-1 pts. wt. dispersant, 0.1-1 pts. wt. anti-settling agent, 0.1-1 pts. wt. corrosion inhibitor, and 15-25 pts. wt. solvent. USE - Used as graphene and carbon nanotube cold-coated zinc anticorrosive coating. ADVANTAGE - The anticorrosive coating: has excellent impact resistance and good flexibility; has a barrier effect on water, oxygen and chlorine, which can extend the anti-corrosion life of the coating, and can reach salt spray resistance of 3600 h without rusting. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene and carbon nanotube cold-coated zinc anticorrosive coating comprising dispersing the modified graphene and modified hydroxylated carbon nanotubes in 10 pts. wt. toluene solution, ultrasonically shaking for 1-2 hours, placing the mixture in a vacuum drying oven, and vacuumizing for 1-3 hours to remove the toluene to obtain a mixture, mixing the mixture, dispersant and half of the solvent, ultrasonically dispersing uniformly, mixing the acrylic resin with the remaining solvent to dissolve, adding the dispersed modified graphene and modified hydroxylated carbon nanotubes to the dissolved acrylic resin to be evenly dispersed, adding zinc powder, anti-settling agent, and corrosion inhibitor to disperse uniformly again to obtain graphene and carbon nanotube cold-coated zinc anticorrosive coating.
