The invention discloses a low temperature impact resistant modified polyvinyl chloride cable material. The cable material is prepared from the following raw materials in parts by weight: 20 to 40 parts of polyvinyl chloride resin, 10 to 15 parts of PET resin, 5 to 9 parts of modified carbon fiber, 2 to 4 parts of nano silicon dioxide, 2 to 4 parts of zinc oxide, 6 to 8 parts of montmorillonite powder, 12 to 14 parts of sepiolite powder, 4 to 6 parts of kieselguhr, 3 to 5 parts of butadiene acrylonitrile rubber powder, 2 to 4 parts of ACR, 1 to 3 parts of TPEE, 4 to 6 parts of DEHP, 0.5 to 1.5 parts of calcium-zinc stabilizer, 1 to 2 parts of calcium stearate, 0.5 to 1.5 parts of ageing resistant agent, 0.3 to 0.5 part of antioxidant, 22 to 24 parts of carbon black, 6 to 8 parts of cyanuric acid tripolycyanamide and 12 to 16 parts of auxiliary agent. The cable material processed and formed by the invention has good low temperature resistance, impact resistance, flame retardance and mechanical property, an application range of the cable material is improved, ingredients and a preparation technology of the cable material are simple, saving cost and reducing labor intensity are achieved, and the cable material can meet an actual use requirement.
