Abstract

The invention discloses a preparation method of a magnesium base graphene composite material, and belongs to the technical field of magnesium base composite materials. Firstly, graphene powder is dissolved in a proper amount of anhydrous ethanol solution to prepare graphene ultrasonic dispersion liquid; metal magnesium powder is dissolved in anhydrous ethanol for ultrasonic treatment and mechanical mixing to obtain graphene/magnesium powder mixed liquid; magnesium base graphene composite powder is prepared through vacuum drying after filtration; the composite powder is coated and thermally extruded to prepare a magnesium base graphene consolidation prefabricated blank; and the consolidation prefabricated blank is added in molten metal liquid after the coat is removed, and is stirred through a spiral magnetic field for casting solidification to finally prepare the magnesium base graphene composite material. The preparation method adopts a simple preparation process liable to realize, is low in production cost, wide in material preparation range, safe and environment-friendly, is wide in application and popularization prospect, and is suitable for preparing novel high-performance magnesium base graphene composite material.

Description
