3-5 parts of an anti-aging agent;
and 1-3 parts of a promoter.
4. The rubber steel composite liner of claim 3, wherein the carbon black comprises N330 carbon black, the graphite comprises graphite SG6 and/or graphite SG3, the vulcanizing agent comprises stearic acid, the plasticizer comprises coumarone, the anti-aging agent comprises at least one of anti-aging agent 4010Na, anti-aging agent BLE-W, and anti-aging agent RD, and the accelerator comprises at least one of accelerator CBS, accelerator DM, and accelerator TMTD.
5. A process for manufacturing a rubber steel composite lining board according to any one of claims 1 to 4, comprising the steps of:
(1) Heating the high-manganese wear-resistant steel plate to 180-220 ℃ and preserving heat for 20-40min;
(2) Cold-pressing the high-manganese wear-resistant steel plate and the rubber layer by adopting a die for one-step molding to obtain a wavy high-manganese wear-resistant steel plate;
(3) Cutting screw holes on the wavy high-manganese wear-resistant steel plate, and welding a supporting frame and a lining plate;
(4) And vulcanizing the screw holes, compounding the rubber layer again, polishing and rust removing to obtain the rubber steel compound lining plate.
6. The process for manufacturing a rubber steel composite lining plate according to claim 5, wherein in the step (2), the die is made of a composite material, the die comprises a shell and an inner coating, the shell is made of at least one of carbon die steel, alloy die steel and high-speed steel, and the inner coating comprises at least one of natural graphite, clay, silicon carbide, alumina and silicon carbide.
7. The process for manufacturing the rubber steel composite lining plate according to claim 6, wherein in the step (2), the R value of a fillet of the die is the same as the thickness of the high-manganese wear-resistant steel plate, and lubricating oil is smeared at the pressed fillet of the die when the high-manganese wear-resistant steel plate is cold-pressed once by the die.
8. The process for manufacturing a rubber-steel composite lining plate according to claim 6, wherein in the step (1), the screw holes are vulcanized, the rubber layer is compounded again at the screw holes, and the shape of the rubber layer corresponds to that of a fastening nut matched with the screw holes.
