The invention discloses a wear-resistant PVC knife-scratch fabric and a preparation method thereof, belonging to the technical field of polymer materials. Weighing 100 parts of PVC resin, 30‑40 parts of plasticizer, 20‑30 parts of wear-resistant filler, 8‑15 parts of flame retardant, 2‑3 parts of heat stabilizer, 0.8‑1.5 parts of antioxidant, 0.8‑1.5 parts of ultraviolet absorber and 0.1‑0.2 parts of crosslinking agent, mixing, melt-extruding in a twin-screw extruder, knife-coating on both surfaces of a base fabric layer, water-cooling, solidifying, edge-cutting and winding to obtain a PVC knife-scratch fabric. There is a chemical interaction between the wear-resistant filler treated by a modified coupling agent and the flame retardant. Therefore, the wear-resistant filler and the flame retardant can be highly dispersed and stably present in the surface layer of the PVC knife-scratch fabric, exerting a synergistic effect, endowing the PVC knife-scratch fabric with excellent wear resistance and efficient and safe flame retardant effect. In addition, with the joint action of other raw materials and other parts, the PVC knife-scratch fabric of the invention has excellent comprehensive performance.
