GRAPHENE-REINFORCED MAGNESIUM-BASED COMPOSITE MATERIAL, PREPARATION METHOD FOR SAME, AND APPLICATIONS THEREOF

WIPO Patent Application WO/2022/057232

A1

The present invention relates to a graphene-reinforced magnesium-based composite material, a preparation method for same, and applications thereof. A reinforcer, a magnesium substrate, and a liquid-phase solvent are mixed to produce a suspension; the suspension produced is spray dried to produce a dry powder; the dry powder produced undergoes a molding treatment to produce a block blank; the block blank and a magnesium alloy blank are melted, mixed, and casted to produce the graphene-reinforced magnesium-based composite material. An inexpensive process is employed to prepare the graphene nanoparticle-reinforced magnesium-based composite material, the dispersion and spreading of an agglomerated and pleated industrial-grade graphene material can be implemented by means of one-step mechanical stirring, no mechanical damage is incurred on the graphene material, at the same time, the preparation of the composite material has low requirements on equipment, processing is inexpensive, the production efficiency is high, an interface structure is controllable, and excellent industrial application prospects are provided.
