Example Embodiment
[0015] Example 1: The structure of the conveyor belt of the present invention is as figure 2 As shown, it is composed of upper cover rubber 1, buffer rubber 2, belt core 3, lower cover rubber 4 and edge rubber 5. To achieve the dual effects of impact resistance and high wear resistance, the production of covering rubber is the key. The covering rubber preparation material of this embodiment includes the following components and weight content: 70 parts of natural rubber, 30 parts of synthetic rubber, 1.8 parts of sulfur, 5 parts of zinc oxide, 2.5 parts of stearic acid, 1.8 parts of accelerator, and 55 parts of reinforcing agent. Parts, 11.5 parts of softener and 3 parts of antioxidant, totaling 180.6 parts.
[0016] In terms of rubber materials, natural rubber has good elasticity, strength, adhesion, and process performance, but its abrasion performance is slightly worse, and its impact elasticity is not as good as that of butadiene rubber. Butadiene rubber has good abrasion resi...
Example Embodiment
[0037] Example 2: The production process is basically the same as that of Example 1. The material components of the cover rubber are adjusted appropriately, and the following formula is adopted: 75 parts of natural rubber, 35 parts of synthetic rubber, 2 parts of sulfur, 5 parts of zinc oxide, and hard fat 3 parts of acid, 2 parts of accelerator, 60 parts of reinforcing agent, 13 parts of softening agent, 4 parts of anti-aging agent, totaling 199 parts.
