NOVELTY - Preparation of a rice hulling rubber roller, involves (b) coating silicone rubber slurry to the surface of the polished metal roller core, and drying it, (c) mixing nitrile rubber, neoprene, graphene, stearic acid, wear-resistant materials, rubber accelerators, sulfur, zinc oxide and diethylene glycol, and filtering to obtain the inner layer of rubber, (d) pressing the inner layer of rubber material into a film and coating it on the metal roller core coated with silicone rubber slurry, (e) plasticizing nitrile rubber and white carbon black, and mixing the plasticized rubber and wear-resistant materials, accelerators, stearic acid, diethylene glycol, and calcium powder to obtain an outer layer of rubber, (f) pressing the outer rubber material into a film and covering it on the outside of the inner layer of rubber material to form an inner and outer rubber layer on the metal roller core, and (g) vulcanizing the roller core, and polishing the outer surface for cleaning and packaging. USE - Preparation method of a high wear-resistant rice hulling rubber roller. ADVANTAGE - The hulling rubber roller prepared by the method has the advantages of high breaking strength, strong elasticity, excellent anti-aging performance, and excellent balance. The method prolongs service life of the hulling rubber roller and improves the quality of rice. The method produces high wear-resistant rice hulling rubber roller. DETAILED DESCRIPTION - Preparation method of a high wear-resistant rice hulling rubber roller, involves (a) weighing 200 parts mass nitrile rubber, 100 parts mass neoprene, 150 parts mass white carbon black, 9-12 parts mass wear-resistant materials, 1-4 parts mass rubber accelerator, 12-14 parts mass sulfur, 9-12 parts mass zinc oxide, 5-8 parts mass stearic acid, 1-2 parts mass diethylene glycol, 9-11 parts mass calcium powder, 26-35 parts mass graphene, and appropriate amount of silicone rubber slurry, (b) coating silicone rubber slurry to the surface of the polished metal roller core, and drying it, (c) taking 50 parts mass nitrile rubber, 100 parts mass neoprene, graphene, stearic acid, wear-resistant materials, rubber accelerators, sulfur, zinc oxide and diethylene glycol into the internal mixer for mixing, and filtering the rubber through the rubber filter to obtain the inner layer of rubber, (d) pressing the inner layer of rubber material in step (c) into a film with a calender and coating it on the metal roller core coated with silicone rubber slurry, (e) taking 150 parts mass nitrile rubber and 150 parts mass white carbon black into the internal mixer for plasticizing, putting the plasticized rubber and wear-resistant materials, rubber accelerators, sulfur, zinc oxide, stearic acid, diethylene glycol, and calcium powder into an open mill for mixing to obtain an outer layer of rubber, (f) using a calender to press the outer rubber material into a film and covering it on the outside of the inner layer of rubber material in step (d) to form an inner and outer rubber layer on the metal roller core, and (g) putting the metal roller core containing the inner and outer rubber layer into a vulcanizing tank for vulcanization treatment to obtain a high wear-resistant rice hulling rubber roller, and polishing the outer surface for cleaning and packaging.
