The invention discloses a high-temperature-resistant hydrogenated nitrile base rubber compound and a preparation method thereof. The compound is composed of, by weight, 60-100 parts of hydrogenated nitrile, 10-40 parts of composite masterbatch, 0.5-2 parts of stearic acid, 1-3 parts of antiager MB, 0.5-3 parts of antiager 445, 30-110 parts of carbon black N774, 5-30 parts of plasticizer RS107, 1-8 parts of vulcanizer and 1-3 parts of vulcanizing auxiliary. The preparation method includes mixing and vulcanizing the raw materials to obtain the composite. The preparation method is simple, effective, easy in obtaining and low in cost, a technological bottleneck in the aspect of high temperature resistance of hydrogenated nitrile is broken through, and application range of hydrogenated nitrile rubber is expanded.
