The present invention relates to the field of polymer processing technology, specifically to a preparation method and application of environmentally modified styrene TPE particles. The preparation method for environmentally friendly modified styrene TPE pellets comprises the following steps: S1: Mix styrene TPE and filler oil to obtain mixture A; S2: Add thermoplastic elastomer, filler, and interfacial compatibilizer to mixture A, then uniformly blend in a high-speed mixer to obtain mixture B; S3. Adding additives to mixture B and uniformly mixing in a high-speed mixer to obtain mixture C; S4. Extruding mixture C through a twin-screw extruder to form environmentally friendly modified styrene TPE pellets. This invention eliminates the need for vulcanization processes in traditional running tracks. By employing a specific blend extrusion process and controlling specific process conditions, it produces odorless products with undetectable harmful substances, far exceeding current new track standards while maintaining excellent mechanical properties.
