▎ 摘　　要

NOVELTY - Composite plastic pipe comprises main body where main body consists of reinforcing composite layer, and the reinforced composite layer is formed by adding graphene modified plastic to the periphery of polyvinyl chloride layer. The polyvinyl chloride layer is a tubular substrate made of polyvinyl chloride. The graphene modified plastic is made of 40-60 pts. wt. polymide 12, 30-50 pts. wt. glass fiber, 0.8-3 pts. wt. graphene, 0.5-1.5 pts. wt. nano-zinc oxide, 0.3-2 pts. wt. surfactant, 0.1-2 pts. wt. dispersant, 0.5-2.5 pts. wt. coupling agent and 0.1-0.6 pt. wt. antioxidants. USE - Composite plastic pipe. ADVANTAGE - The product has special comprehensive mechanical performance and safety performance, better anti-puncture effect, has dual protection and corrosion resistance and good high temperature resistance property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite plastic pipe comprising taking composite plastic pipe mold used for preparing composite plastic pipe materials, placing molten polyvinyl chloride raw material in the inner mold, uniting the outer mold and the inner mold, pouring molten graphene modified plastic into the composite plastic pipe mold, using self-adhesion of graphene modified plastic, filling the graphene modified plastic into the outer mold, bonding with the polyvinyl chloride layer, depressurizing and standing at room temperature for 3-5 days.
