▎ 摘  要

NOVELTY - Graphene-reinforced ethylene propylene diene monomer rubber comprises 30-50 pts. wt. ethylene, 20-40 pts. wt. propylene, 45-55 pts. wt. third monomer, 0.6-1.4 pts. wt. catalyst, 900-1200 pts. wt. organic solvent, 0.02-0.05 pts. wt. terminating agent, 0.005-0.03 pts. wt. stabilizer, 15-30 pts. wt. graphene oxide and 10-15 pts. wt. reducing agent. USE - Used as graphene-reinforced ethylene propylene diene monomer rubber. ADVANTAGE - The graphene-reinforced ethylene propylene diene monomer rubber: has improved tensile strength and improved overall strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene-reinforced ethylene propylene diene monomer rubber, comprising (i) replacing air in a reaction kettle sufficiently with an inert gas, adding third monomer, graphene oxide, catalyst and organic solvent, introducing mixed gas of ethylene and propylene, then pressurizing to 0.5-1.8 MPa, and reacting at 40-60 degrees C for 40-50 minutes in hydrogen gas flow atmosphere to obtain a first colloidal solution, (ii) adding stabilizer into the first colloidal solution, reacting at normal temperature for 50-60 minutes under normal pressure condition to obtain a second colloidal solution, (iii) adding reducing agent into the second colloidal solution, and reacting at 40-80 degrees C for 4-6 hours to obtain third colloidal solution, (iv) transferring the third colloidal solution into a flocculation tank, carrying out flocculation at 80-95 degrees C under a pressure of 0.35-0.45 MPa, then removing the solvent to obtain a colloid gel, and (v) dehydrating the colloid gel by a dehydrator, and drying by a dryer to obtain final product.
