▎ 摘　　要

NOVELTY - Coating comprises a base paint comprising 8-12 pts. wt. epoxy resin, 1-3 pts. wt. modified graphene powder, 0.1-0.3 pts. wt. anti-settling agent, 7-35 pts. wt. xylene, 3-15 pts. wt. n-butanol, 0.01-0.03 pts. wt. antifoaming agent, and 0.03-0.05 pts. wt. flatting agent, where the modified graphene powder is graphene oxide grafted with silver powder on the surface. USE - Coating. ADVANTAGE - The coating has high conductivity and low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included fo a method for preparing a coating, which involves: (A) mixing 1-3 pts. wt. graphene oxide and 100-300 pts. wt. xylene, carrying out ultrasonic vibration for 0.5-1 hours; (B) adding 0.1-0.3 pts. wt. coupling agent, reacting at 50-70 degrees C for 6-10 hours, and performing suction filtration and washing; (C) adding 100-300 pts. wt. xylene and 2-3 pts. wt. nano-silver powder, reacting at 60-80 degrees C for 6-10 hours, and subjecting to suction filtration and washing; (D) adding 1000-3000 pts. wt. water and 1.5-3 pts. wt. hydrazine hydrate, reacting in a water bath at 90-95 degrees C for 1-1.5 hours, performing filtration, washing, and vacuum drying to obtain modified graphene powder; and (E) mixing 1-3 pts. wt. modified graphene powder with 8-12 pts. wt. epoxy resin, 0.1-0.3 pts. wt. anti-settling agent, 7-35 pts. wt. xylene, 3-15 pts. wt. n-butanol, 0.01-0.03 pts. wt. antifoaming agent and 0.03-0.05 pts. wt. flatting agent to obtain a coating containing graphene.
