The invention discloses a wear-resistant and oil-proof PVC elevator cable material. The wear-resistant and oil-proof PVC elevator cable material consists of the following raw materials in parts by weight: polyvinyl chloride resin 100 parts, a rubber and plastic component 10-40 parts, a plasticizer 40-60 parts, epoxy soybean oil 3-5 parts, a filler 10-50 parts, wear-resistant powder 2-10 parts, a thermal stabilizer 2-5 parts, an oxidation inhibitor 0.25-1.5 parts, a lubricant 0.1-1 part, and a modifier 0.5-2.5 parts. The invention further discloses a preparation method of the wear-resistant and oil-proof PVC elevator cable material. The preparation method comprises the following steps: first step, preparing raw materials, and accurately weighing various materials proportionally; second step, mixing the materials uniformly and carrying out preplasticizing; third step, extruding, mixing and pelleting by a double-stage double-screw extruder, wherein the temperature range of the extruder is 140-175 DEG C; fourth s
