The invention discloses an ultra-wear-resistant and high-strength conveyor belt comprising cover rubber. The cover rubber is composed of butadiene rubber and natural rubber in a weight ratio of (60‑90):(30‑50). A sulfur vulcanization system is adopted, with accelerator NS, accelerator DM, accelerator D, sulfur and carbon black N220 or N234 in a weight ratio of (0.5‑2):(0.1‑0.3):(0.1‑0.3):(1‑3):(40‑60). The product is manufactured by one-step forming using a twin-screw extruder and a calender. The finished conveyor belt has ultra-high tensile strength and abrasion resistance. Third-party laboratory tests show that its wear resistance service life is 5 to 6 times that of conventional Class D wear-resistant formulas, and its overall service life is doubled or longer.
