As the price of raw materials for tires increases, the production cost of bias tires increases. In order to reduce production costs, increase the utilization rate of rubber products for bias tire production and reduce the consumption of auxiliary materials, it is a work that formulators need to improve. The rubber products used for the production of bias tires mainly relate to rubber mold pads, vulcanized water tire mouth mats and the like. Since the rubber mold pad and the vulcanized water tire mouth pad are used under long-term high temperature and high pressure conditions, the rubber compound used is required to have good heat-resistant oxygen aging property and compression set resistance. At present, the basic raw material for rubber products for the production of bias tires is mainly natural rubber (NR). Because of its high unsaturated rubber, it has poor heat resistance, ozone resistance and weather resistance, which seriously affects the service life of rubber Umi mba’e ojejapóva..
