▎ 摘　　要

NOVELTY - Tubular product comprises a pipe main body and a functional layer covered on the surface of the pipe main body, where functional layer adopts functional composite material, and the functional composite material comprises 100 pts. wt. matrix resin, 1-20 pts. wt. functional masterbatch and 1-5 pts. wt. compatibilizer; the matrix resin is PE-RT and/or PB; the functional masterbatch is modified graphene and nano titanium dioxide in a mass ratio of 1-7:100; the modified graphene is obtained by grafting and modifying graphene oxide; the graphene oxide is a single layer with carboxy and hydroxy groups on the surface. USE - The tubular product is useful for garden flower planting and heating. ADVANTAGE - The tubular product solves the problem that algae are easy to grow on the inner and outer walls. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing tubular product for garden flower planting and heating, comprising uniformly mixing matrix resin, modified graphene /nano titanium dioxide functional masterbatch and compatibilizer, and melting to obtain a molten functional composite material, extruding the molten functional composite material and the pipe main body on the same extruder, where the extruded functional composite material is covered on the outer part of the pipe main body to form a functional layer of the pipe, the pipe is processed 500-1500 GHz microwave treatment.
