▎ 摘  要

NOVELTY - Graphene anticorrosive primer comprises main agent A and auxiliary agent B in the mass ratio of 3:1-6:1, where the main agent A comprises 20-40 pts. wt. polymer resin, 5-15 pts. wt. diluent, 1-5 pts. wt. graphite alkene blocking agent, 8-20 pts. wt. inorganic filler, 6-15 pts. wt. film forming agent and 3-6 pts. wt. defoamer, and the auxiliary agent B comprises 1-3 pts. wt. initiator, 10-15 pts. wt. curing agent and 5-15 pts. wt. active diluting agent. USE - The graphene anticorrosive primer is useful for heat exchangers in a marine environment in the anticorrosion of the surface of the metal blades. ADVANTAGE - The graphene anticorrosive primer: has good heat dissipation and anticorrosive performance; improves the adhesion, weather resistance and abrasion resistance of the coating; and makes the coating more lightweight. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM are also included for preparing graphene anticorrosive primer comprising (1) mixing the components of the main agent A uniformly, (2) mixing the components of auxiliary B uniformly and (3) adding the auxiliary agent B to the main agent A before use, mixing and curing for 30-120 minutes.
