The invention discloses an antibacterial and toughened polyethylene plastic pipe and a preparation method thereof. The pipe comprises the following raw materials in parts by weight: 100–150 parts of high-density polyethylene, 10–20 parts of modified polystyrene, 10–20 parts of ketone/silanized polyimide blend, 5–10 parts of HFR‑3000, 5–10 parts of basic magnesium sulfate whisker, 1–4 parts of nano zinc oxide, 1–3 parts of flame retardant, 1–5 parts of lubricant and 1–5 parts of antioxidant. The polyethylene plastic pipe provided by the invention has excellent rigidity, toughness and flexibility, greatly enhanced durability and practicality, outstanding impact resistance and favorable antibacterial performance. It solves the technical defects of easy cracking, poor impact resistance and low toughness of conventional high-density polyethylene pipes, and meets the domestic production requirements for antibacterial plastic pipes.
