The invention discloses ethylene propylene diene monomer rubber capable of alleviating colour fusion and a preparation method of the ethylene propylene diene monomer. The ethylene propylene diene monomer capable of alleviating the colour fusion comprises the following components in parts by mass: 140 parts of ethylene propylene diene monomer rubber, 100-120 parts of low-medium reinforcement carbon black, 50-70 parts of inert filler, 60-100 parts of oil, 0.8-1.5 parts of sulphur, 1-1.5 parts of accelerant and 1-3 parts of stearic acid. The inert filler is added in the raw materials, functional groups on the surface of carbon black can be effectively absorbed, the low-medium reinforcement carbon black and oil are added in steps, a slipping phenomenon in a mixing process can be avoided, and the rubber can be heated normally; impurities are filtered before mixed materials are extruded, so that colour fusion of the rubber can not be caused by the impurities.
