NOVELTY - Graphene stripping agent, prepared by a chemical reaction between a first substance and a second substance, and the first substance is an organic substance having 3-10 aromatic rings and 3-10 carboxylic acid groups and the second substance is long-chain alkylamines or long-chain alkyl alcohols with C16-C18 carbon chain length. USE - The graphene stripping agent is useful for preparing graphene modified rubber (claimed). ADVANTAGE - The graphene stripping agent prepares graphene with high yield, few defects and regular structure by combining with the rubber and improving the interface bonding effect of the rubber macromolecule long chain structure. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing graphene, comprising mixing the graphite powder fully with a stripping agent and a solvent and mechanically stripping to obtain a graphene slurry with a solid content of 1-5%, where the stripping agent adopts the graphene stripping agent; Graphene modified rubber comprises 100 pts. wt. rubber, 5-15 pts. wt. graphene, 15-35 pts. wt. carbon black, 5-8 pts. wt. active agent, 2-5 pts. wt. anti-aging agent, 1-3 pts. wt. sulfur powder and 1-2 pts. wt. accelerator, where the graphene is prepared as mentioned above; and Preparing graphene modified rubber, comprising adding the rubber latex particles into the polar organic solvent, stirring mechanically, mixing evenly, adding the graphene slurry, stirring mechanically for 2-5 hours to obtain a uniform mixed solution, casting and drying the mixed solution to obtain a rubber masterbatch, mixing the rubber masterbatch with rubber latex, carbon black, active agent, anti-aging agent, sulfur powder, accelerator, kneading and mixing uniformly, and vulcanizing to obtain graphene modified rubber, preferably the polar organic solvent comprises at least one tetrahydrofuran, N-dimethylformamide, methyl ethyl ketone, methyl isobutyl ketone, chloroform and/or ethyl acetate.
