NOVELTY - Graphene composite rubber material comprises 100-120 pts. wt. nitrile rubber, 25-35 pts. wt. organosilicone resin, 20-30 pts. wt. acrylic resin, 10-15 pts. wt. sepiolite powder, 8-12 pts. wt. dicumyl peroxide, 7-10 pts. wt. gelatin, 5-8 pts. wt. barium stearate, 5-8 pts. wt. diisononyl phthalate, 4-6 pts. wt. oleyl alcohol polyoxyethylene ether phosphate, 3-5 pts. wt. graphene, 2-5 pts. wt. conductive carbon black, 1-3 pts. wt. silane coupling agent, 3-5 pts. wt. dispersant and 3-5 pts. wt. anti-aging agent. USE - Used as graphene composite rubber material. ADVANTAGE - The graphene composite rubber material is heat-conducting and electricity-conducting (claimed), and has excellent mechanical strength, and low production cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene composite rubber material comprising (i) taking raw material, (ii) taking graphene, sepiolite powder, conductive carbon black, and adding water, grinding for 3-5 hours to obtain 450-550 meshes slurry, and spray drying to obtain powder, where spray dryer inlet temperature is 250 degrees C, and outlet air temperature is 180 degrees C, (iii) adding nitric acid to powdery material, reacting for 5-15 minutes, drying, adding into mixer, then adding orderly nitrile rubber, organosilicone resin, acrylic resin, dicumyl peroxide and gelatin, mixing at 95-100 degrees C for 25-30 minute, then adding barium stearate, diisononyl phthalate, oleyl alcohol polyoxyethylene ether phosphate and silane coupling agent, and mixing for 5-10 minute, (iv) adding dispersing agent, anti-aging agent and 20 pts. wt. de-ionized water to step (iii) obtained product, and performing ultrasonic treatment for 2.5-3 hours to obtain raw material suspensions, where frequency of ultrasonic treatment is 25-30 KHz, and power of the ultrasonic treatment is 1200-1300 W, (v) drying step (iv) obtained product, then adding into twin-screw extruder, melting at 370-390 degrees C, filtering, extruding at rotating speed of 180-200 revolutions per minute under pressure of 15-18 KPa, and (vi) cooling, stretching at a stretching ratio of 3.2-3.5 times, and then hot molding at 280 degrees C to obtain final product.
