DETAILED DESCRIPTION - An Independent claim is included for preparing high sealing resilience ethylene propylene diene rubber, which involves preparing amphiphilic cellulose nanocrystal/graphene mixed water dispersion, where cellulose nanocrystals are extracted from cotton, wood, bamboo, sisal and other plants and sea squirt animals by sulfuric acid hydrolysis, 2-15 pts. wt. cellulose nanocrystals is dispersed in 200-400 pts. wt. deionized water, 2-15 pts. wt. graphene oxide is added and stirred at 60degreesC, dispersed by ultrasonic for 30-150 min, temperature is kept constant at 60degreesC, then mixed dispersion is put in a microwave oven, temperature of the microwave oven is controlled at 120degreesC, the reaction time is 20-90 s, and the graphene oxide is thermally reduced by microwave radiation and cellulose nanocrystal/graphene water dispersion with amphiphilicity is obtained, constructing cellulose nanocrystal/graphene oriented layered hybrid network by dissolving 100 pts. wt. ethylene propylene diene monomer completely in 300-1000 pts. wt. cyclohexane, adding amphiphilic cellulose nanocrystal/graphene aqueous dispersion to the ethylene propylene diene monomer solution, performing strong magnetic stirring for 30-60 minutes, distributing cellulose nanocrystals/graphene stably at the water-cyclohexane interface to form a stable water-in-oil emulsion system, removing aqueous and cyclohexane phases by freeze-drying, obtaining ethylene propylene diene rubber-coated cellulose nanocrystals/graphene three-dimensional hollow spherical shells, using pressure of 3-6 Mega Pascal at room temperature for 2 min, adjusting cellulose nanocrystal/graphene hybrid network to be oriented and arranging in layers in the ethylene propylene diene monomer matrix to obtain an unvulcanized ethylene propylene diene monomer /cellulose nanocrystal/graphene composite adhesive, adding 0.5-5 pts. wt. zinc oxide, 0.2-4 pts. wt. stearic acid, 0.4-3 pts. wt. anti-aging agent successively and mixing, then adding 0.3-4 pts. wt. vulcanization accelerator, 0.5-6 pts. wt. vulcanizing agent, obtaining ethylene propylene diene monomer /cellulose nanocrystal/graphene mixed rubber, parking for 24 hours, performing hot-press vulcanization at 150-180degreesC and 10-20 MPa for 3-18 min and obtaining ethylene propylene diene monomer/cellulose nanocrystal/graphene nanocomposite rubber.
