NOVELTY - Preparing rubber soles involves adding 45-55 pts. wt. butadiene rubber, 20-25 pts. wt. EPDM rubber, 6-12 pts. wt. nitrile rubber, 5-10 pts. wt. methyl methacrylate, 3-4 pts. wt. zinc oxide, 3-6 pts. wt. stearic acid, 3-6 pts. wt. graphene, 1.2-1.4 pts. wt. accelerator, 40-50 pts. wt. white carbon black, 10-20 pts. wt. paraffin oil, and 1-3 pts. wt. sulfur, putting the butadiene rubber, EPDM rubber and nitrile rubber into the kneader to make the kneader to ensure that the roller distance of the kneader is below 1mm, plasticize for 3-5 minutes. The plasticized material is placed in the opener again for plasticizing, ensuring that the roller distance of the opener is below 1mm, plasticized for 8-10 minutes to obtain semi-finished mixed rubber. USE - Method for preparing rubber soles. ADVANTAGE - The method enables to prepare rubber soles that effectively improves the plasticity of the rubber compound by repeatedly thinning the rubber-making raw materials, the resilience of the rubber compound, flexibility of the finished product, and the comfort level. DETAILED DESCRIPTION - Preparing rubber soles invcolve adding 45-55 pts. wt. butadiene rubber, 20-25 pts. wt. EPDM rubber, 6-12 pts. wt. nitrile rubber, 5-10 pts. wt. methyl methacrylate, 3-4 pts. wt. zinc oxide, 3-6 pts. wt. stearic acid, 3-6 pts. wt. graphene, 1.2-1.4 pts. wt. accelerator, 40-50 pts. wt. white carbon black, 10-20 pts. wt. paraffin oil, and 1-3 pts. wt. sulfur, putting the butadiene rubber, EPDM rubber and nitrile rubber into the kneader to make the kneader to ensure that the roller distance of the kneader is below 1mm, plasticize for 3-5 minutes. The plasticized material is placed in the opener again for plasticizing, ensuring that the roller distance of the opener is below 1mm, plasticized for 8-10 minutes to obtain semi-finished mixed rubber. The mixed rubber compound is added with methyl methacrylate, zinc oxide, stearic acid, graphene, accelerator, white carbon black, paraffin oil and sulfur to the mixer so as to obtain finished mixed rubber. The prepared compound is filled into a syringe, then injected the compound into the lower mold through the syringe, and closed the mold. The mold is put into the pressure table for 4-6 minutes, and the curing temperature is 140-155 degrees C. The mold is taken out, then opened the mold, and removed the finished shoe sole. An INDEPENDENT CLAIM is included for a ejection device for a rubber sole mold, which comprises an upper mold, where lower mold is provided on a lower surface of the upper mold.
