【Task】 An anti-vibration rubber material having improved anti-vibration characteristics at low temperatures while maintaining heat resistance, and an automobile engine mount using the same. [Solution] An anti-vibration rubber material mainly composed of a copolymer of 2-chloro-1,3-butadiene and 2-methyl-1,3-butadiene. The copolymerization amount of 2-methyl-1,3-butadiene contained in the copolymer is preferably 1 to 46 mol%, and the range of 2,3-dichloro-1,3-butadiene is 15 mol% or less. It is preferable that it is copolymerized with. By using a thiourea vulcanization accelerator and an imidazole compound as a compounding agent, a more suitable vibration-proof rubber material is provided. The anti-vibration rubber material can be vulcanized by vulcanization, and the vulcanized rubber can be used as an anti-vibration rubber material, particularly an automobile engine mount.
