USE - The method is useful in preparing graphene thermally conductive anticorrosion integrated aqueous coating. ADVANTAGE - The aqueous coating has excellent thermal conductivity in both horizontal and vertical directions, and excellent anti-corrosion performance at the same time. DETAILED DESCRIPTION - Preparing graphene thermally conductive anticorrosion integrated aqueous coating comprises (i) adding 1-5 pts. wt. polyhydroxy-containing surface treatment agent into a mixed solution of 95 pts. wt. ethanol and water, stirring at a speed of 100-1000 revolutions per minute for 5-10 minutes, then adding 10-1000 pts. wt. thermally conductive filler, and continue stirring for 10-60 minutes to obtain thermally conductive filler with polyhydroxy groups on surface, (ii) adding 1-5 pts. wt. worm-like graphene into 100 pts. wt. absolute ethanol, then adding 100-1000 pts. wt. the thermally conductive filler prepared in step (i), finally adding 1-5 pts. wt. diisocyanate and mixing at a high speed of 800-2000 revolutions per minute for 10-60 minutes, filtering and drying to obtain composite material of worm-like graphene/thermally conductive filler, (iii) adding 1-5 pts. wt. polyamino-containing surface treatment agent into the mixed solution of 95 pts. wt. ethanol and water, and then adding 10-1000 pts. wt. composite material prepared in step (ii), continue stirring at a speed of 100-1000 revolutions per minute for 5-10 minutes to obtain thermally conductive filler with polyamino groups on the surface, and (iv) mixing 1-80 pts. wt. thermally conductive filler prepared in step (iii), 1-99 pts. wt. aqueous resin, 0-50 pts. wt. deionized water, 0.1-1 pt. wt. anti-settling agent, 0.1-1 pt. wt. substrate wetting agent, 0.1-1 pt. wt. defoamer, and 0.1-1 pt. wt. leveling agent, stirring at a speed of 100-3000 revolutions per minute for 10-200 minutes, then sand grinding until the coating fineness is less than 40 μm, and then adding 1-10 pts. wt. crosslinking agent to obtain final product.
