The invention discloses a high-performance PVC plastic pipe and a preparation method thereof. The PVC plastic pipe material includes the following raw materials by weight: 100 parts of PVC resin, 10-20 parts of chlorinated polyethylene, 1-3 parts of PA-20 processing aid, and 10-3 parts of MMA/S-nano montmorillonite composite material. 20 parts, stabilizer 3-5 parts, lubricant 1-2 parts, antioxidant 0.5-2 parts, filler 1-3 parts. The PVC plastic pipe of the invention has the advantages of better impact resistance, heat resistance, pressure resistance, good thermal stability and tensile strength, good plasticizing performance, easy processing and the like, and effectively solves the problem of existing PVC pipes. Rigid but not tough, poor impact resistance and crack resistance, and poor processing plasticity, etc., have broad application prospects. |
