The invention provides rubber for an underground carry-scraper tire, a preparation method of the rubber and the underground carry-scraper tire. The preparation method of the rubber for the underground carry-scraper tire comprises the following steps: S1, mixing a vulcanizing aid, a filler, rubber and a first solvent to obtain a pre-mixture, and continuously introducing the pre-mixture into a reactor for solvent separation to obtain a rubber master batch; s2, after the master batch is internally mixed, protective wax and tear-resistant resin are added for mixing, and first-section master batch is obtained; s3, mixing the primary masterbatch with a first accelerant and a first vulcanizing agent, and performing final mixing to obtain final mixed rubber; and S4, performing vulcanization treatment on the final mixed rubber to obtain vulcanized rubber. The rubber material prepared by the method for continuously preparing the master batch has excellent processability and mechanical property, and the prepared vulcanized rubber has excellent tensile property, tearing property and the like, can adapt to harsh working environments, and is particularly suitable for preparing underground carry-scraper tires.
本发明提供了一种井下铲运机轮胎用橡胶和其制备方法、井下铲运机轮胎。该井下铲运机轮胎用橡胶的制备方法包括:步骤S1,将硫化助剂、填料、橡胶和第一溶剂混合,得到预混合物,将预混合物连续通入反应器内进行溶剂分离,得到母胶;步骤S2,将母胶经密炼后,加入防护蜡、抗撕裂树脂进行混炼,得到一段母炼胶;步骤S3,将一段母炼胶与第一促进剂、第一硫化剂进行混合,进行终炼,得到终炼胶;步骤S4,将终炼胶进行硫化处理,得到硫化橡胶。本申请通过上述连续式的制备母炼胶的方法制备的胶料在加工性能和机械性能上表现优越,制得的硫化橡胶具有优异的拉伸、撕裂等性能,能够适应苛刻的工作环境,特别适合用于井下铲运机轮胎的制备。
