The invention relates to the technical field of silicone rubbers, and concretely relates to an antistatic silicone rubber for electric wires, and a preparation method thereof. The antistatic siliconerubber comprises, by weight, 90-110 parts of composite silicone rubber, 45-55 parts of a reinforcing agent, 2.5-3.5 parts of hydroxy-terminated polydimethylsiloxane, 1.5-2.5 parts of dimethicone, 35-45 parts of an antistatic component, 0.3-0.7 part of a titanate coupling agent, 0.15-0.25 part of a mold lubricant and 5.5-6.5 parts of a vulcanizing agent. The antistatic agent is used to reduce the volume resistivity of the material in order to make the silicone rubber have a good electromagnetic shielding effect and a good electrical conduction property, so electrostatic charges in the electricwires are transmitted outwards to achieve the antistatic effect; and the reinforcing agent, hydroxy-terminated polydimethylsiloxane, dimethicone and other materials are adopted, so the obtained silicone rubber has the advantag
