NOVELTY - Modified ethylene propylene diene rubber comprises 100 pts. wt. ethylene propylene diene monomer raw rubber, 5-10 pts. wt. accelerator, 40-80 pts. wt. reinforcing agent, 1-5 pts. wt. anti-aging agent, 10-30 pts. wt. softening agent, 3-10 pts. wt. hyper-branched phosphorus amide modified graphene oxide, and 1-3 pts. wt. vulcanizing agent. USE - Used as modified ethylene propylene diene rubber. ADVANTAGE - The rubber has high mechanical property, flame retardant property and heat conductivity, limiting oxygen index can reach 25%. The method is simple and easy to realize, and capable of large batch production, and good for industrial popularizing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified ethylene propylene diene rubber comprising using the ultra-branched phosphorus amide-modified graphene oxide and softening, dispersing ultrasonic under the condition of 30-80 degrees C, obtaining mixture, adding the mixture with ethylene propylene diene monomer raw rubber, accelerating agent, reinforcing agent and anti-aging agent, to obtain the modified ethylene propylene diene monomer parent gel, mixing 30-60 degrees C, mixing the modified ethylene propylene diene monomer parent glue with curing agent at 30-60 degrees C for 8-24 hours, to obtain the modified diene rubber, vulcanizing the modified diene rubber, and gross rubber for 8-24 hours, obtaining modified ethylene propylene diene rubber. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the preparing modified ethylene propylene diene rubber (Drawing includes non-English language text).
