description The invention provides a high-impact and high-tensile PVC (polyvinyl chloride) material and a preparation method thereof. The high-impact and high-tensile PVC material comprises the following components in parts by mass: 50-70 parts of PVC resin and 15-25 parts of a toughening agent, wherein the toughening agent is composed of ABS high rubber powder and CPE, and the mass ratio of the ABS high rubber powder to the CPE is 8: 2-6: 4. The composition further comprises 0.5-2.0 parts of a lubricant, 1.5-3 parts of a stabilizer, 0.5-2 parts of a processing aid and 5-20 parts of a filler. The preparation method comprises the following steps: weighing the raw materials, uniformly mixing to obtain a mixture, adding the mixture into a conical twin-screw extruder, melting, extruding, granulating and cooling to obtain a target product. The high-impact and high-tensile PVC material has outstanding mechanical properties such as excellent impact strength, tensile strength, tensile elongation at break and the like, also has c
