Using maleic anhydride grafted polyolefin elastomer (POE-g-MAH) and ethylene propylene diene monomer (EPDM) as toughening agents, recycled PP/glass fiber/POE-g-MAH and recycled PP/glass fiber/EPDM composites were prepared by open mixing method. The effect of POE-g-MAH and EPDM content on the mechanical properties, melting and crystallization behavior, rheological properties and structure of the composites were studied. The results show that when the content of POE-g-MAH and EPDM is 30%, the impact strength of composites are increased by 290% and 433%, respectively. POE-g-MAH has a certain degree of hindrance to the crystallization of recycled PP and reduces the crystallization ability of recycled PP. EPDM has little effect on the crystallization process of recycled PP. POE-g-MAH forms a good interfacial interaction with matrix and glass fiber, improving the toughness of composite. EPDM improves the impact toughness of composite by force deformation, while maintaining good tensile strength and tensile modulus. [ABSTRACT FROM AUTHOR] |
