example 1
[0028] Take 80g of nitrile rubber, 3g of zinc oxide, 1g of stearic acid, and 1g of anti-aging agent H, and add them into the torque rheometer for mixing for 8 minutes. The temperature is controlled at 120°C and the speed is 80r / min. Dioctyl phthalate, 1g sublimed sulfur, continue to mix for 8min, cool to room temperature to get the mixed rubber, place the mixed rubber on a flat vulcanizer, preheat at 120°C for 15min, then heat at 160°C, 8MPa Molded and vulcanized for 10 minutes, taken out and made into a sheet with a thickness of 3 mm, and cooled to room temperature to obtain a damping rubber. Take 20 g of titanate coupling agent and 50 g of silane coupling agent and add it to 1.0 L of deionized water. Stir at 300r / min for 3 hours, add 500g of acetone after cooling to room temperature, and put it into a centrifuge for centrifugation, take the upper layer solution to distill under reduced pressure to remove acetone, and obtain a macromolecular coupling agent, take 50g of macromo...
