[0055] In order to specifically illustrate the method for preparing vulcanized rubber of the present invention, a preferred embodiment is provided below for illustration:
[0056] (1) Put the rubber matrix in the internal mixer, the speed is 50-120rpm, the initial mixing temperature is 70-90°C, and the raw rubber mastication time is 0.1-1min; then the mixture containing the initiator and Component A of the rubber modifier is introduced into the above-mentioned internal mixer for the first mixing to obtain a section of masterbatch;
[0057] (2) Add the one-stage masterbatch and component B containing white carbon black, activator, anti-aging agent, carbonate and softener into the internal mixer for the second mixing, discharge and park for 3-5 hours , to obtain the second-stage masterbatch;
[0058] (3) Set the speed of the internal mixer to 50-100rpm, and the initial mixing temperature to 25-50°C. After masticating the second-stage masterbatch for 0.5-1.5 minutes, add compone...
