The invention belongs to the field of injection molding materials, and specifically relates to a packaging injection molding composite material capable of adsorbing magnets and a preparation method thereof. The packaging injection molding composite material capable of adsorbing magnets comprises the following raw materials: ABS rubber powder, iron powder, a lubricant and a coupling agent. The preparation method comprises the following steps: mixing ABS rubber powder, iron powder, a lubricant and a coupling agent, and extruding in a twin-screw extruder to obtain a premix; introducing the premix into a single-screw extruder connected in series with the twin-screw extruder, and performing extrusion, cooling, strand drawing and granulation to obtain the packaging injection molding composite material capable of adsorbing magnets. The packaging injection molding composite material capable of adsorbing magnets of the invention can be directly adsorbed with magnets, solving the problem of mutual adsorption between magnets during transportation; in addition, the magnets are adsorbed on the packaging injection molding composite material, which can also avoid damage caused by shaking and collision during transportation.
