The invention discloses a graphene/carbon nano tube hybridized filler network enhanced rubber material and a preparation method thereof. According to the rubber material, graphene and carbon nano tubes are taken as filler, a hybridized filler network is formed in a rubber material matrix, wherein 100 parts by mass of the rubber material matrix are adopted, and 0.1-20 parts by mass of graphene and the carbon nano tubes are adopted. The rubber material is prepared according to steps as follows: oxidized graphene and the carbon nano tubes are added to water, and a hybridized suspension liquid is prepared; the prepared hybridized suspension liquid is added to an emulsion of the rubber material matrix and mixed, a demulsifier is added for demulsification, an oxidized graphene/carbon nano tube/rubber particle suspension liquid is prepared, then, a reducing agent is added for a reduction reaction, solid-liquid separation is performed after sufficient reaction, an obtained solid phase is washed and dried, and the rubber material is prepared. The graphene and the carbon nano tubes form the hybridized filler network in the rubber material and have an energy dissipation function, so that the rubber material has excellent mechanical property, fatigue resistance, crack growth resistance and conductive property.
