▎ 摘　　要

NOVELTY - Composite material prepared by (a) pre-treating the nano-nickel chromite particles, modifying the graphene oxide and treated nano-nickel chromite particles with silane coupling agent by sol-gel method, then drying, and grinding to obtain nano-nickel chromite/graphene oxide powder, and (b) mixing polyethylene and dispersant uniformly, then adding nano-nickel chromite/graphene oxide powder, stirring, dispersing, vacuum drying, then antifoaming, and placing in a mold for adding and vulcanizing to obtain nano-nickel chromite/graphene oxide/polyethylene composite material, is claimed. USE - The material is useful for aluminum-plastic composite pipe. ADVANTAGE - The material: has excellent corrosion resistance, wear resistance, oxidation resistance and high strength. DETAILED DESCRIPTION - INDEPENDENT CLIAMS are also included for: (1) composite material for aluminum-plastic composite pipes prepared by the above method; (2) corrosion-resistant aluminum-plastic composite pipe comprising inner layer (1), inner hot melt layer (2), middle layer (3), outer hot melt layer (4) and outer layer (5) connected to each other. The inner layer is nano-nickel chromite/graphene oxide/polyethylene composite pipe made of composite material. The inner layer hot melt is polyamide or polyester amide. The middle layer is an aluminum tube. The outer layer hot melt is polyamide or polyester amide. The outer layer is nano-nickel chromite/graphene oxide/polyethylene composite pipe made of composite material; and (3) corrosion-resistant aluminum-plastic composite pipe made prepared by the above method. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the corrosion-resistant aluminum-plastic composite pipe. Inner layer (1) Inner hot melt layer (2) Middle layer (3) Outer hot melt layer (4) Outer layer (5)
