The invention relates to a high-wear-resistance low-heat-generation synthetic natural rubber composite material as well as a preparation method and application thereof, which belong to the technical field of synthetic natural rubber. The technical problem of poor processability of synthetic natural rubber in the prior art is solved, and the tensile strength, elongation at break, wear resistance, high temperature resistance and compression heat generation performance of the synthetic natural rubber are further improved. The synthetic natural rubber composite material is prepared from the following components in parts by weight: 100 parts of polyisoprene rubber, 55-65 parts of reinforcing filler, 1-2 parts of stearic acid, 4-5 parts of zinc oxide, 1-2 parts of an anti-aging agent, 1-2 partsof a flow aid, 5-8 parts of aromatic hydrocarbon oil, 3-5 parts of a rubber modifier, 1.5-2 parts of a vulcanizing agent and 0.5-2 part of an accelerant. The synthetic natural rubber composite material has good processability and comprehensive performance, and is suitable for being used on treads of automobile tires and high-wear-resistance parts of other special tires.
