This invention discloses a method for improving the toughness of waste plastics, falling within the field of waste plastic recycling technology. It comprises the following steps: Step 1: Weigh raw materials; Step 2: Prepare modifier A; Step 3: Prepare modifier B; Step 4: Prepare toughening filler; Step 5: Add modifier B to the molten PET plastic aggregate, followed by the toughening filler. After complete addition, cool and maintain temperature; Step 6: Add modifier A to the molten ABS plastic aggregate. After complete addition, heat and maintain temperature; Step 7: Add the product from Step 6 to the product from Step 5 and mix thoroughly; Step 8: Extrude the mixture from Step 7 through a twin-screw extruder, followed by cooling, pelletizing, and drying. Through this method, the plastic produced by the present invention achieves a tensile strength of 48.3 MPa and an elongation at break of 691%, demonstrating excellent toughness properties. This enhances the application scope of recycled plastics while reducing environmental pollution and resource waste.
