7. A method for preparing the anti-fatigue damping vulcanized rubber as set forth in claim 1, comprising the steps of:
Placing 60-100 parts of chlorinated butyl rubber and 10-50 parts of trans-1, 4-polyisoprene rubber into a kneader for stirring, then sequentially adding 1-4 parts of zinc oxide, 1-3 parts of stearic acid, 0.5-2 parts of accelerator, 2-5 parts of plasticizer, 20-50 parts of white carbon black and 0.5-2 parts of sulfur component, mixing, and discharging to obtain a damping filler master batch mixture; cooling the damping filler master batch mixture to room temperature, and standing to obtain damping filler master batch;
according to parts by weight, placing 80-100 parts of phenyl silicone rubber into a kneader for stirring, adding 10-40 parts of white carbon black for mixing, adding 15-25 parts of damping filler masterbatch and 1-4 parts of plasticizer after mixing, and discharging after continuing mixing to obtain a mixed rubber;
And cooling the rubber compound to room temperature, adding 1-2 parts of vulcanizing agent, standing the thin through piece on an open mill, and vulcanizing to obtain the anti-fatigue damping vulcanized rubber.
8. The method of claim 7, wherein the vulcanization comprises the following specific operations: the rubber compound is placed on a flat vulcanizing machine, vulcanized for 8-15 minutes at 160-180 ℃, and then placed in a blast oven for vulcanization for 1.5-2.5 hours at 190-210 ℃ to obtain the anti-fatigue damping vulcanized rubber.
