The invention discloses a cable material for new energy vehicles, and belongs to the technical field of cable material preparation. The cable material is prepared from polyvinyl chloride resin, SEBS rubber resin, styrene-butadiene rubber, PVC resin, ammonium polyphosphate, aluminum hydroxide, magnesium hydroxide, a silicon-containing hydrogen base, cellulose ether, carbon black N330, glass fiber,sodium silicate, chlorinated paraffin, dimethyl silicone oil, expanded vermiculite, a modified heat-resistant agent, vinyl triethoxysilane, an accelerant TMDT, zinc oxide, stearic acid, an antiager RD, a silane coupling agent A187 and tetrabromobisphenol A; the cable material for the new energy vehicles is obtained by preparing the base materials, preparing the modified materials and then mixing the main materials and the modified materials. The prepared cable material has the excellent heat resistance.
