Preparation method of magnesium-based composite material for thixotropic injection molding and prepared magnesium-based composite material

The invention discloses a preparation method of a magnesium-based composite material for thixotropic injection molding and the prepared magnesium-based composite material, and belongs to the field of preparation of high-performance metal materials. The preparation method comprises the following steps: 1, preparing slurry: adding the reinforcer, the modifier and the adhesive into the solvent, and stirring and dispersing; and 2, coating the magnesium particles: coating the prepared slurry on the surfaces of the magnesium alloy particles, and simultaneously drying at high temperature. The preparation method of the magnesium-based composite material has the advantages of multiple types of reinforcements capable of being added and high content, rapid coating can be achieved, the coating layer in the prepared magnesium-based composite material is uniform in distribution and firm in film forming, can be effectively bonded and bound together with magnesium alloy particles, and is suitable for being used as a supply r
