主　　题：Wood-plastic composites Polypropylene Reprocessing Antioxidant 

摘      要：This study assessed the life cycle of biocomposites with antioxidants by repeated *** effects of antioxidants on the life cycle of wood flour/polypropylene(PP)composites were determined by analyzing their mechanical and thermal *** composites were repeatedly processed for seven times with pelletizing and *** antioxidant,pentaerythritoltetrakys 3-(3,5-ditert-butyl-4-hydroxyphenyl)propionate,was *** mechanical strength of the biocomposites decreased after *** transformed infrared analysis showed that thermo-oxidative aging occurred during *** thermal performance of the resulting composites decreased because of *** flour/PP has a long lifetime and antioxidants can slow the thermo-oxidative and mechanical degradation during reprocessing.
