Wood-plastic Composites Prepared by Waste Polypropylene and Toughening

摘要

The feasibility of wood-plastic composite (WPC) and efficiency of impact strength improvement by toughening agents were discussed using waste polypropylene (PP) from e-wastes as experimental materials. The researching results indicated that it could be used in manufacturing wood-plastic composite while the impact strength of waste PP decreased by 47.3% comparing with new PP. Adding polyethylene octene elastomer (POE) and styrene-butadiene-styrene (SBS) could effectively enhance the impact strength of WPC. When adding 15% of POE and SBS individually, the impact strength increased by 113.2% and 43.4%. The modulus of rupture (MOR) and modulus of elasticity (MOE) lowered when toughening agents were added, which should be made into consideration in practical application according to the property of materials comprehensively.
