▎ 摘　　要

NOVELTY - Preparing graphene/white carbon black hybrid filler comprises (i) adding silane coupling agent single-end silicon hydrogen into the graphene slurry for reaction, preparing the modified graphene slurry, and drying to obtain the modified graphene, (ii) taking silane coupling agent the white carbon black, and drying to obtain modified white carbon black, (iii) mixing the modified graphene with the organic solvent to obtain modified graphene slurry, mixing the modified white carbon black with the organic solvent, and preparing the modified white carbon black slurry, and (iv) reacting the modified graphene slurry and modified white carbon black slurry under the action of the catalyst B to obtain graphene/white carbon black mixed slurry, and drying. USE - The method is useful for preparing graphene/white carbon black hybrid filler. ADVANTAGE - The filler has high tensile strength and heat conductivity coefficient, low rolling resistance, compressing raw heat and abrasion volume. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Graphene/white carbon black hybrid filler prepared according to above mentioned method. Vulcanized rubber, comprising the graphene/white carbon black hybridized filler.
