▎ 摘  要

NOVELTY - Graphene complex damping rubber material comprises 100 pts. wt. rubber, 40-60 pts. wt. reinforcing filling agent, 3-4 pts. wt. anti-aging agent, 5-8 pts. wt. nano zinc oxide, 1-1.5 pts. wt. stearic acid, 0.8-1.5 pts. wt. vulcanizing agent, 2-3.5 pts. wt. vulcanization aid, 0.4-0.75 pts. wt. graphene, 2-3 pts. wt. coupling agent, and 3-5 pts. wt. anti-ozone agent. USE - Used as graphene complex damping rubber material. ADVANTAGE - The material: has excellent processing and bonding performance with metal piece, spinnability, low heat generation, small creep, fatigue and cold resistance, great economic value and wide application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene complex damping rubber material comprising (i) treating nano-zinc oxide and graphene are with a coupling agent, adding neoprene on the open mill, keeping the roller distance to 0.1mm, the roller temperature is lower than 40 degrees C, and thin passing for 6-8 times before use, (ii) blending natural rubber and high-vinyl polybutadiene are in an internal mixer in accordance with the specific ratio, mixing temperature is controlled at 110-120 degrees C, for 5-6 minutes, thin passing for 4 times on the open mill, and rolling down for 12 hours, placing compound rubber, antioxidant, stearic acid and anti-ozonant into the mixer and mixing for 120 seconds, adding the reinforcing agent and plasticizer in turn, mixing for 180 seconds, the mixer temperature at 130-135 degrees C, and discharging the tablets, and allowing to stand the compounded rubber for 24 hours, (iii) placing resultant into the internal mixer for hot smelting at 120 degrees C, placing the vulcanizing agent and accelerator, discharging the rubber after 20 seconds on the open mill, keeping the roll distance of 0.1mm, thin passing for 3 times, and hit three triangle bags, turning left and right for 6 times, and leaving the next piece for 8 hours, and (iv) adding graphene premix and blending with rubber cool roller on the open mill, maintaining the graphene premix refined in step (i) and the compound rubber refined in step (iii) at a roll distance of 0.1 mm, where the roller temperature is lower than 40oC, thin pass for 4-6 times, passing left and right for 4-6 times.
