Weather-proof flame-retardant PVC cable material for charging pile

Belonging to the technical field of cables, the invention discloses a weather-resistant flame retardant PVC cable material for charging piles, which is prepared from the following raw materials by weight: 100 parts of PVC resin, 45-55 parts of a plasticizer, 8-12 parts of a flame retardant, 4-6 parts of a calcium/zinc composite stabilizer, 30-40 parts of calcined clay, and 1-1.2 parts of a lubricant. A compound of DOTP and DOP is taken as a main plasticizer, so that a good toughening effect can be achieved, and the weather resistance of the PVC cable material can be improved; the novel flame retardant is synthesized through a chemical means and is applied to the PVC cable material, so that the flame retardance of the cable material can be remarkably improved, the ageing resistance of the PVC cable material can be improved, and the weather resistance of the PVC cable material is further improved; the main plasticizer and the main plasticizer have a synergistic effect, so that the PVC cable material has good to
