NOVELTY - Preparing graphene/rubber composite material involves preparing a graphene suspension and a rubber solution. The rubber solution is sprayed into the graphene suspension by jetting to obtain a graphene/rubber mixture. The graphene / rubber mixture is dried to obtain a graphene/rubber material. USE - Method for preparing graphene/rubber composite material (claimed). ADVANTAGE - The method enables to prepare graphene/rubber composite material, which has excellent surface state. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a apparatus for preparing graphene/rubber composite material, which comprises shell, where inner cavity of the shell is a mixing chamber, and is provided with graphene suspension inlet, a first nozzle and a second nozzle, respectively, which are in communication with the mixing chamber, where one end of the first nozzle located in the shell is a first nozzle outlet, other end is the first nozzle inlet, diameter of the first nozzle outlet is smaller than the diameter of the first nozzle inlet, one end of the second nozzle located in the shell is a second nozzle inlet, the other end is the second nozzle outlet and diameter of the second nozzle outlet is smaller than the diameter of the second nozzle inlet; (2) a method for using apparatus for producing a graphene / rubber composite material, which involves flattening shell and causing graphene suspension inlet facing upward; (3) injecting the prepared graphene suspension from the graphene suspension inlet into the mixing chamber of the shell; (4) injecting the prepared rubber solution into the mixing chamber from the first nozzle in a jetted manner and mixing with the graphene suspension in the mixing chamber; and (5) collecting graphene / rubber mixed liquid formed by mixing the graphene suspension with the rubber solution at the outlet of the second nozzle.
