▎ 摘  要

NOVELTY - Method for preparing fluorinated nitrile rubber involves (i) adding 100 parts mass fluorinated graphene to 600-1000 parts mass ethanol, ultrasonically treating in ice water mixture for 8-12 hours, fully dispersing the fluorinated graphene, dripping 1200-1500 parts mass ionic liquid to the fluorinated graphene dispersion, stirring in ice water mixture to obtain ionic liquid modified fluorinated graphene emulsion, and (ii) adding 5-20 parts mass ionic liquid and 100 parts mass nitrile latex to fluorinated graphene emulsion, ultrasonically dispersing for 30 minutes to 1 hour, adding the mixed solution of nitrile latex and ionic liquid modified fluorinated graphene to the agglomeration kettle, stirring the mixture for 30 minutes, adding 3-15 parts mass coagulant and 20-100 mass parts soft water, stirring for 2-5 hours at 50-70 degrees C curing, washing, dehydration and drying to obtain the product.
