The invention discloses a high-performance synthetic rubber product to overcome the problems of complex preparation processes, low strength, poor toughness and high cost of synthetic rubber products in the prior art. A preparation method for the high-performance synthetic rubber product comprises the following steps: step 1, mixing, by weight, 100 parts of raw rubber, 6 to 14 parts of isoprene, 4 to 8 parts of styrene, 8 parts of butadiene, 1.5 parts of a promoter, 0.5 part of a modifier, 4 parts of stearic acid, 3 parts of zinc oxide, 70 parts of carbon black, 6 to 10 parts of modified polyester fiber, 0.5 part of an antioxidant and 2 to 4 parts of silicon dioxide rigid particles; step 2, putting a mixed material obtained in the previous step into an emulsion for polymerization; step 3, adding a suspending agent to allow the mixed material to realize monodisperse suspension polymerization; step 4, soaking a mixed sample obtained in the previous step in a soaking solution and carrying out filtering so as to obtain a semi-finished product; and step 5, subjecting the semi-finished product to vulcanization and molding. The preparation method is low in cost, simple in process and capable of improving the performance of the synthetic rubber product.
