▎ 摘  要

NOVELTY - Conductive coating comprises 100 pts. wt. epoxy resin, 20-100 pts. wt. polyamide curing agent, 100-300 pts. wt. solvent, 80-165 pts. wt. zinc powder, 2.5-5 pts. wt. graphene, 30-60 pts. wt. tin powder (low melting point tin-based alloy powder), 8-16 pts. wt. mica powder, 1-2 pts. wt. talc powder, 6-13 pts. wt. toughening agent, 1-2 pts. wt. gas phase silica, 2-4 pts. wt. organic bentonite, 6-13 pts. wt. dispersant and 1-2 pts. wt. leveling agent. USE - The conductive coating is useful for high current lightning strikes, and in ground net protection and anti-corrosion in buried section of lightning conductor. ADVANTAGE - The conductive coating has excellent adhesion, flexibility and conductivity, where the coating does not fall off after experiencing a high current lightning strike, and maintains excellent corrosion resistance and electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the conductive coating, involving (i) dissolving epoxy resin in solvent, adding gas phase silica, organic bentonite and toughening agent, stirring at 3000 rpm for 10 minutes, adding zinc powder, graphene, tin powder, mica powder, talc powder, dispersant and leveling agent, and ball milling in a ball mill for 1-3 hours to obtain component (A), (ii) mixing polyamide curing agent with solvent, and uniformly stirring to obtain component (B), and (iii) uniformly mixing components (A) and (B) and coating.
