The invention discloses a process for preparing a plastic pipe, comprising the following steps: S1. Preparing raw materials: selecting according to the following parts by weight: 40-70 parts of polypropylene resin, 50-70 parts of polyvinyl chloride resin, and 30 parts of nano-level antibacterial masterbatch -60 parts, 1-4 parts of polytetrafluoroethylene resin, 1-2 parts of triphenyl phosphite, 2.5-3.5 parts of triethyl citrate, 1-5 parts of calcium carbonate, 1-5 parts of silicon powder, stearin 2.2-2.8 parts of butyl acid, 2-8 parts of bentonite, 1-3 parts of epoxidized soybean oil, and 1.2-1.6 parts of antioxidant synergist; S2. Prepare the first mixture; S3. Prepare the second mixture; S4. Extrude out of shape. By adding nano-level antibacterial masterbatch, the invention makes the plastic pipe have antibacterial properties, has a killing effect on bacteria in water and can inhibit the growth of bacteria, and keeps the water quality clean and hygienic at the same time. , Polytetrafluoroethylene resin, the plastic pipe has excellent mechanical properties, flame retardancy and antibacterial properties, in addition, the plastic pipe has stable anti-aging, high temperature resistance and corrosion resistance. |
