▎ 摘　　要

NOVELTY - Auxiliary agent comprises 1-10 pts. wt. graphene, 20-99 pts. wt. solvent, 0.5-5 pts. wt. dispersant, 1-10 pts. wt. silane coupling agent and 0.1-1 pts. wt. anti-settling agent. USE - The auxiliary agent is useful for epoxy zinc-rich primer (claimed). ADVANTAGE - The auxiliary agent: has simple preparation method, good controllability and easy industrial production; can enhance the adhesive force, flexibility, and impact resistance of the coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the auxiliary agent, comprising (i) mixing the graphene, silane coupling agent and 75-90% solvent, ultrasonic dispersing for 1-3 hours to obtain mixed solution 1, (ii) adding dispersant, anti-settling agent and the remaining solvent into the mixed solution 1, ultrasonically dispersing for 1-3 hours to obtain the graphene containing coating agent.
