▎ 摘　　要

NOVELTY - Coating mixture comprises 30-40 pts. wt. epoxy resin emulsion, 5-8 pts. wt. graphene powder, 40-50 pts. wt. zinc powder, 20-30 pts. wt. composite powder, 5-10 pts. wt. aluminum, 2-3 pts. wt. dispersant, 7-10 pts. wt. polyamide, 3-5 pts. wt. ethylene glycol ether, 0.2-0.5 pts. wt. polydimethylsiloxane, and 20-25 pts. wt. deionized water. USE - The mixture is useful for substrate immersed in seawater. ADVANTAGE - The mixture has good corrosion protection effect; and maintains good electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the mixture, comprising (i) introducing epoxy resin emulsion, graphene powder, zinc powder, composite powder, aluminum tripolyphosphate, nd dispersant into 50 wt.% deionized water into a stirrer and stirring at 2000-2800 revolutions/minute for 30-40 minutes to obtain mixed material A; (ii) introducing polyamide, ethylene glycol ethyl ether and deionized water (remaining amount) into the stirrer and stirring at 1200-1500 revolutions/minute for 20-30 minutes to obtain mixed material B; and (iii) mixing mixed material A and mixed material B in the stirrer, slowly adding polydimethylsiloxane, and stirring uniformly to obtain target product.
