▎ 摘　　要

NOVELTY - Preparing degradable zinc-based composite material with high strength and antibacterial properties, comprises (a) performing hydrothermal reduction to graphene oxide and copper acetate as raw material, and ascorbic acid as reducing agent to obtain cuprous oxide modified graphene powder; (b) ball-milling and alloying pure zinc powder and alloy element powder by using planetary ball mill to obtain zinc alloy powder; (c) uniformly dispersing cuprous oxide modified graphene powder in zinc alloy powder using planetary ball mill to obtain mixed powder of cuprous oxide modified graphene and zinc alloy; (d) sintering mixed powder of cuprous oxide modified graphene and zinc alloy to obtain sintered cuprous oxide modified graphene reinforced zinc alloy matrix composite material; and (e) hot-extruding the sintered cuprous oxide-modified graphene-reinforced zinc-silver alloy-based composite material to further improve its mechanical properties, and finally obtaining final product. USE - The method is useful for preparing degradable zinc-based composite material with high strength and antibacterial properties. ADVANTAGE - The method solves the problem of poor mechanical property caused by bad interface bonding performance between the graphene base composite material in the zinc base composite material, improves the interface performance between the reinforcing body and zinc base body through in-situ reaction between the cuprous oxide and zinc base body, and obtains zinc-based composite material with high strength and antibacterial.
