▎ 摘　　要

NOVELTY - Preparing graphene/carbon nanotubes coordinated modified polyvinyl chloride composition, comprises taking graphene carbon nanotube composition material, polyvinyl chloride resin, organic tin, chlorinated polyethylene, stearic acid, white oil, titanium dioxide and calcium powder, placing into the first solvent, mixing uniformly, forming a graphene/carbon nanotube/polyvinyl chloride blend material, after drying, to obtain non-solvent-based graphene/carbon nanotubes in synergistically modified polyvinyl chloride composition. USE - The graphene/carbon nanotube co-modified polyvinyl chloride composition material is useful in the preparation of a feed water pipe (claimed). ADVANTAGE - The composition material has cold brittle at low temperature; and improves weathering and anti-aging performance.
