▎ 摘　　要

NOVELTY - Graphene-based multi-component epoxy anti-corrosion paint comprises component A, component B and component C in a weight ratio of 2-5:1:0-0.2, where component A includes 100 pts. wt. epoxy resin, 10-30 pts. wt. toughening agent, 0.1-3 pts. wt. graphene sheets less than 1 micron, 20-50 pts. wt. active diluent, 0.1-3 pts. wt. silane coupling agent, 0.1-2 pts. wt. dispersant and 0-2 pts. wt. pigment; component B includes 10-20 pts. wt. polyamide, 5-20 pts. wt. polyetheramine and 5-12 pts. wt. modified fatty amine; and component C includes fast curing agent and ethanol. USE - The paint is useful for pipelines (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing graphene-based multi-component epoxy anti-corrosion paint comprising (i) mixing epoxy resin, toughening agent and 1/2 mass of active diluent, adding pre-mixed graphene sheets less than 1 micron, 1/2 quality active diluent, silane coupling agent, dispersant, pigment and stirring to obtain component A, (ii) mixing polyamide, polyether amine and modified fatty amine to obtain component B, and (iii) dispersing curing agent and ethanol to obtain component C; and (2) use method comprising mixing component A and component B, coating on the surface of the pipe until there is no rogue, spraying component C on the coating and then evaporating ethanol.
