The invention discloses an antislip impact-resistant prefabricated surface material for PVC (polyvinyl chloride) plastic tracks and a preparation method thereof. The antislip impact-resistant prefabricated surface material for PVC plastic tracks is made from 10-30 parts of a modified paper-plastic compound, 100 parts of PVC resin, 2.5-5 parts of a stabilizer, 65-90 parts of plasticizer DOTP, 5-10parts of plasticizer DOA, 7-15 parts of an anti-impact modifier, 0.3-3.5 parts of an antioxidant, 0.5-1.5 parts of an ultraviolet absorbent, 2-9 parts of an ionomer forming agent, 7-15 parts of a wear-resistant nonslip agent, 2-7 parts of an expander, 5-12 parts of nano zinc oxide, 0.3-3 parts of silicone powder, 40-90 parts of a filling material, and 0.5-3.5 parts of a pigment. The antislip impact-resistant prefabricated surface material for PVC plastic tracks, prepared herein, is green, provides good comfort and safety, and shows good slip resistance, impact resistance, tensile strength andelongation at break.
