NOVELTY - Fluorine rubber/graphene composite masterbatch comprises 0.1-10 pts. wt. graphite oxide, 5-300 pts. wt. fluorine rubber latex, 0.1-100 pts. wt. reducing agent and 0.1-30 pts. wt. demulsifier. USE - Used as fluorine rubber/graphene composite masterbatch. ADVANTAGE - The method is simple, suitable for industrial production and has low energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the fluorine rubber/graphene composite masterbatch comprising (i) dispersing the graphite oxide in a solvent to obtain an oxidized graphite solution; (ii) adding fluorine rubber latex to graphite oxide solution, dispersing and adding reducing agent and dispersing to obtain the fluorine rubber/graphene composite emulsion; and (iii) adding demulsifier to fluorine rubber/graphene composite emulsion, demulsifying and drying.
