NOVELTY - Preparation of titania/graphene-modified butyronitrile composite rubber, involves adding hydrochloric acid aqueous solution to a mixed solution of ethanol and benzyl alcohol, and stirring to obtain solution (A), adding titanium tetrachloride to a mixed solution of ethanol and benzyl alcohol, and stirring to obtain solution (B), simultaneously dripping solution (B) and graphene oxide solution in solution (A), stirring at high speed to obtain a titania/graphene oxide composite sol, adding the sol to a supercritical fluid device, extracting under the action of supercritical carbon dioxide fluid, drying to obtain a titania/graphene oxide composite nanopowder, vacuum heating and reducing the nanopowder to obtain a titania/graphene composite nanopowder, adding the nanopowder to a butyronitrile emulsion, stirring, adding a precipitator, shearing, washing, and drying. USE - Preparation of titania/graphene-modified butyronitrile composite rubber (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the titania/graphene modified butyronitrile composite rubber comprising titania/graphene composite nanopowder and butyronitrile emulsion in a mass ratio of 1:80-100.
