NOVELTY - Wear and cold resistant elastic wrapping roller material comprises 100 pts. wt. natural rubber, 3-9 pts. wt. sulfur, 2-4 pts. wt. promoter M, 1-3 pts. wt. stearic acid, 1-5 pts. wt. zinc oxide, 10-20 pts. wt. carbon black, 10-20 pts. wt. ultrafine calcium carbonate, 1-2 pts. wt. motor oil, 0.1-0.3 pts. wt. graphene, 1-5 pts. wt. carboxymethyl cellulose, 5-15 pts. wt. quartz sand and 0.5-1.5 pts. wt. molybdenum disulfide. USE - The wear and cold resistant elastic wrapping roller material is useful for belt conveyor roller (claimed). ADVANTAGE - The roller material: has high mechanization degree in production process, excellent elasticity; requires less labor, and low production cost; can buffer the fluctuation of the steel roller body which may cause the conveyor belt to ensure the material transportation is more stable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing wear and cold resistant elastic wrapping roller material, comprising (1) providing each raw material, (2) starting the double roller rubber mixing machine, adjusting the front roller temperature to 54-60 degrees C and back roller temperature to 50-58 degrees C, (3) placing the natural rubber between the two rollers, carrying out mastication operation for 4-6 minutes, makes that uniformly covered on the front roller, removing the glue layer, adjusting the roller distance to 1-2 mm, and continuing mastication for 4-6 minutes, (4) adding promoter M, stearic acid, zinc oxide, carbon black, ultrafine calcium carbonate, machine oil to the rubber in the step (3), adjusting roller distance to 3-4 mm, roller temperature to 40-48 degrees C, and mixing for 6-8 minutes, (5) adding sulfur, carboxymethyl cellulose, quartz sand into the mixed rubber obtained in the step (4), adjusting roller distance to 3-4 mm, and roller temperature to 52-60 degrees C, and mixing for 10-20 minutes, (6) adding graphene, and molybdenum disulfide into the mixed rubber obtained in the step (5), adjusting roller distance to 1-3 mm, and roller temperature to 56-66 degrees C, mixing for 5-15 minutes, and ramming for 2-4 times, (7) adjusting the roller distance to 3-4 mm, the lower piece, and (8) vulcanizing the rubber of the lower piece, where vulcanization temperature is 150-160 degrees C, and vulcanization time is 20-30 minutes.
