The invention discloses a tear-resistant and anti-cutting new energy automobile wire harness rubber sheath and a preparation method thereof, and the sheath material comprises the following components in parts by mass: 175 parts of ethylene propylene diene monomer, 0.2-1.0 part of a vulcanizing agent, 4-8 parts of a vulcanization accelerator, 0.2-1.0 part of a vulcanization control agent, 100-150 parts of a filler, 30-50 parts of a softening agent, and 0.4-1.0 part of a scorch retarder. Wherein the vulcanization control agent is a multi-element hindered phenol compound. The rubber compound is prepared through the step-by-step open mixing technology that the ethylene propylene diene monomer, the scorch retarder and the vulcanization accelerator are subjected to melt blending, then the filling agent, the softening agent, the vulcanizing agent and the vulcanization control agent are added, then the rubber compound is subjected to vulcanization forming through an injection molding machine, and the wire harness rubber sheath is obtained and has the effects of tear resistance, cutting resistance and aging resistance.
