[0034] Example 1
[0035] A rubber adhesive, in terms of weight percentage, the rubber adhesive consists of the following components:
[0036]
[0037] The preparation method of the above rubber adhesive includes the following steps:
[0038] (1) Put liquid rubber into the reaction kettle first, and the liquid rubber is obtained by mixing liquid polybutadiene and hydroxyl-terminated liquid polybutadiene uniformly;
[0039] (2) Add sulfur, accelerator ZBEC, antioxidant, dehumidifier, carbon black and zinc oxide to the liquid rubber obtained in step (1) in sequence, and stir for 10 minutes under vacuum;
[0040] (3) Open the reactor, add heavy calcium carbonate to the mixture obtained in step (2) above, stir for 10 minutes in vacuum, then open the reactor, add the coated calcium carbonate and talc to the reactor, and stir for 10 minutes in vacuum;
[0041] (4) Open the reactor, scrape off the mixture obtained in the above step (3) attached to the wall of the reactor, and stir under vacuum ...
