Belonging to the field of environmental-friendly materials, the invention relates to a method for preparing novel automobile bumper materials from waste polyolefin plastics. The steps are as follows: S1, collecting waste polyolefin plastic particles; S2, cleaning, drying and crushing into fine granules; S3, blending waste polyolefin particles with modified additives in a fixed proportion; S4, melt blending in a twin-screw extruder; S5, injection molding and cooling shaping to produce bumper materials. Functional groups of modified additives produce synergistic effects to enhance interfacial bonding, flexibility and structural stability, thereby improving the comprehensive performance of recycled polyolefin materials.
