firstly, plasticated natural rubber, styrene butadiene rubber and butadiene rubber are put into an internal mixer for mixing for 40-50 seconds, 50% of carbon black, CMoSSI wear-resistant agent and aromatic oil are put into the internal mixer, mixing is continued for 180 seconds after 150-fold addition of materials, then zinc oxide, stearic acid, anti-aging agent, protective wax, 50% of carbon black and coumarone resin are put into the internal mixer for 180 seconds after 150-fold addition of materials, the rubber discharge temperature is 140-fold addition of materials at 150 ℃, sheets are taken out and cooled, a section of mixed rubber is prepared, and the mixed rubber is used after being placed for 8 hours;
4) and (3) second-stage mixing:
the two-stage mixing uses an internal mixer, and the rotor speed of the internal mixer is 20 r/min;
the first-stage rubber compound, sulfur, an accelerant and an anti-scorching agent are put into an internal mixer for mixing for 100-120 seconds, the rubber discharge temperature is 90-100 ℃, and the mixture is taken out and cooled to prepare a second-stage rubber compound;
(2) preparing an intermediate layer rubber material;
(3) rolling out the sheet;
(4) cold press molding;
(5) and (4) vulcanizing the flat plate.
