NOVELTY - Method for preparing emulsion polymerized styrene-butadiene rubber from modified graphene, involves (a) adding 600-1000 parts mass ethanol to beaker, adding 100 parts mass graphene, ultrasonically reacting in an ice water mixture for 8-12 hours, fully dispersing graphene, dripping 1000-1500 parts mass ionic liquid in the graphene dispersion and stirring for 6-10 hours in an ice water mixture to obtain the ionic liquid modified graphene emulsion and (b) adding 20-100 parts mass soft water and 100 parts mass styrene-butadiene latex to a coagulation kettle, stirring and mixing, adding 5-20 parts mass ionic liquid modified graphene emulsion and 0.3-1 part mass methyl cellulose, stirring and mixing for 30 minutes, adding 3-15 parts mass demulsifier, stirring and mixing for 30 minutes, adding 5-15 parts mass coagulant, stirring for 2-5 hours at 80-100 degrees C, curing, washing, dehydrating and drying. USE - The method is used for preparing emulsion polymerized styrene-butadiene rubber from modified graphene.
