The invention discloses high-temperature-resistant strong-resilience high-safety mixed rubber, and is characterized in that the mixed rubber comprises the following components by the weight percentage: 10-30% of natural rubber, 5-10% of chloroprene rubber, 5-10% of polyisoprene, 4-6% of polybutadiene, 5-15% of white carbon black, 8-12% of a silicon alkyl coupling agent, 10-20% of methyl vinyl silicone rubber, 3-4% of tetravinyltetramethylcyclotetrasiloxane, 1-2% of a catalyst, 1-3% of dimethyl hydroxyl silicone oil, 8-10% of dihydroxydiphenylsilane, 2-3% of a heat stabilizer, 2-3% of a surface modification agent, 5-8% of zinc oxide, 1-2% of stearic acid, 2-6% of sulfur, 1-2% of an accelerator, and 1-3% of other auxiliary agents. The wear resistance is improved, the life problem is overcome, introduction of butyl rubber is known to be capable of improving a wet-skid resistance ability of the mixed rubber, and the obtained mixed rubber has excellent mechanical properties, resilience and high-temperature resistance; and through innovating a rubber mixing technology and changing a feeding sequence, a portion of parts of the sulfur is put in masterbatch rubber to prolong the rubber scorching time, and the rubber processing safety performance is ensured.
