▎ 摘　　要

NOVELTY - A graphene heavy-duty anti-corrosion coating is prepared by mixing the component (A) and the component (B) with a mass ratio of 100: (30-35). The component (A) is phenolic aldehyde modified epoxy resin liquid. The component (B) is an organic amine curing agent. The component (A) comprises 20-50 pts. wt. phenolic modified epoxy resin, 10-25 pts. wt. quartz sand, 10-25 pts. wt. epoxy active diluent, 0.5-2 pts. wt. high amine-based density modified graphene, 1-1.5 pts. wt. leveling agent or anti-shrinkage agent, 0.5-2 pts. wt. anti-settling agent or thixotropic agent and 1-3 pts. wt. defoaming agent. The component (B) comprises 25-50 pts. wt. organic amine, 20-50 pts. wt. quartz sand and 1-2 pts. wt. anti-settling agent. USE - Graphene heavy-duty anti-corrosion coating for outer wall of soil-covered storage tank for storing of crude oil. ADVANTAGE - The method uses high amine-based density modified graphene with low conductivity, excellent compatibility, dispersibility, improves the performance of a coating film, and avoids the risk of corrosion acceleration. The coating film has excellent barrier property, mechanical property, adhesive force, wear resistance, water resistance and chemical resistance, excellent matching property with ensured cathode protection, and the corrosion prevention period can reach more than 20 years in a soil environment.
