The invention discloses a silicone rubber alcoholysis product as well as a preparation method and application thereof, and belongs to the technical field of polymer engineering plastics. The alcoholysis method of the silicone rubber comprises the following steps: mixing the silicone rubber with an alcoholysis agent, and carrying out alcoholysis reaction at 200-250 DEG C for 12-48 hours to obtain a silicone rubber alcoholysis product; the alcoholysis agent is unsaturated fatty alcohol with the carbon chain length of 3-10. According to the modified nitrile rubber provided by the invention, the silicone rubber alcoholysis product prepared by a specific alcoholysis method is introduced as a modifier, so that the obtained modified nitrile rubber has excellent processability, tensile strength and cold resistance; the silicone rubber alcoholysis product provided by the invention can solve the problem that the existing waste silicone rubber is difficult to recycle and treat, and achieves the effects of efficiently ut
