▎ 摘　　要

NOVELTY - Graphene-corrosion material composition comprises 12-20 pts. wt. graphene powder, 60-80 pts. wt. graphene powder, 4-6 pts. wt. epoxy resin, 6-8 pts. wt. coupling agent, 8-12 pts. wt. dispersant, 2-4 pts. wt. defoaming agent, 20-25 pts. wt. additive and 25-35 pts. wt. solvent. USE - The composite graphene-corrosion material is useful for forming a shielding layer on a steel structure surface, where the steel structure is used in the industry. ADVANTAGE - The composite graphene anti-corrosion material has excellent corrosion resistance, and is prepared in a simple and cost effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of graphene-corrosion material composition comprising: (S1) obtaining each raw material according to the ratio; (S2) adding the epoxy resin, dispersing agent, anti-settling agent, defoaming agent into the solvent, and fully and uniformly mixing to obtain the mixed solution; (S3) adding graphene powder, and coupling agent in the dispersion, and fully stirring and mixing to obtain the mixed slurry; and (S4) adding the additive into the mixed slurry obtained in step (S3), and fully stirring to obtain the finished product.
