NOVELTY - Graphene oxide and rubber masterbatch are mixed in an internal mixer for 1-5 minutes. White carbon black and coupling agent, or white carbon black surface-modified with coupling agent are added and mixed for 1-20 minutes to obtain a graphene oxide/white carbon black/rubber nanocomposite. Or, white carbon black and rubber masterbatch are mixed, and then graphene oxide and interface agent are added and mixed. Or, all the components are co-mixed for 1-20 minutes. USE - Mechanical-blending of graphene oxide/white carbon black/rubber nanocomposite (claimed). ADVANTAGE - The method provides graphene oxide/white carbon black/rubber nanocomposite in which graphene and white carbon black are inserted with each other. Hence, self-aggregation of the two fillers is effectively suppressed and composite having excellent dispersibility is obtained. The composite has high modulus, low rolling resistance, and excellent wear resistance and tear resistance. Because of the lamellar structure and good self-recovery capability of graphene oxide, the rubber material has excellent gas-barrier property and self-healing property. The method is simple, easy and economical. DETAILED DESCRIPTION - Graphene oxide and rubber masterbatch are mixed in an internal mixer for 1-5 minutes.
