摘要： 采用熔融共混法制备了二次纤维/废渣粒子混杂增强废地膜复合材料，考察了增容处理和微波辐照对混杂增强废地膜复合材料力学性能和结晶性能的影响。结果表明，经增容处理和微波辐照后，复合体系的力学性能均有较大幅度地提高。结晶性能研究结果表明，增容处理和微波辐照处理对废地膜混杂复合材料的结晶峰温度和结晶度影响一致，结晶峰温度分别比纯混杂复合材料低1.3 ℃和0.8 ℃；结晶度分别比纯混杂复合材料高0.3 ％和2.49 ％；然而，两种处理方式对废地膜复合材料的结晶速率影响不同，前者使结晶速率减慢，后者使结晶速率略有提高。

Abstract: The composite of second-handed-fiber and waste particle reinforced post-consumer mulch films was prepared via melt mixing. A compatibilizer (PE-g-MA) and microwave irradiation were employed to improve the mechanical performance and crystallization behavior of the composite. The compatibilizer and microwave irradiation caused the crystallization peak temperature of the composite reduced by 1.3 ℃ and 0.8 ℃ , and the crystallinity increased by 0.3 % and 2.49 %, respectively, compared with neat composite. The compatibilizer made the crystallization rate reduce, and microwave irradiation made the crystallization rate enhanced.

Key words: hybrid composite, waste mulch film, compatibilizer, microwave irradiation, crystallization behavior, mechanical property
