The invention discloses a plastic pipeline, which includes the following raw materials: HDPE high density polyethylene, LLDPE linear low density polyethylene, nano zirconium dioxide, nano silicon carbide, nano calcium carbonate, nano bamboo charcoal powder, a silane coupling agent, an anti-aging agent, a defoaming agent, an antistatic agent, an antibacterial agent and titanium dioxide loaded withthe antibacterial agent. Nano zirconium dioxide, nano silicon carbide, nano calcium carbonate and nano bamboo charcoal powder are used as mixed auxiliary materials for preparing the pipeline; the nanoparticles have a large specific surface area, and have a good cross-linking effect with HDPE and LLDPE, the strength of the polymer material can be improved, the thermal stability, wear resistance andcorrosion resistance of the material can be enhanced, a significant acceleration effect is achieved on the plastic pipeline, and the tensile strength of the plastic pipeline can be effectively improved.
