摘要： 以木粉和废旧聚烯烃塑料为原材料制备了废旧聚烯烃/木粉复合材料，讨论了不同助剂对复合材料加工性能的影响，并进一步探讨了马来酸酐接枝聚丙烯（PP-g-MAH）用量对复合材料的加工性能、力学性能以及微观结构的影响。结果表明，在复合材料中同时添加PP-g-MAH和乙烯-醋酸乙烯脂（EVA），其加工性能明显优于只添加EVA的复合材料；EVA用量为2 %时，PP-g-MAH用量高于9 %时，复合材料具有较低的剪切扭矩和熔融能耗；PP-g-MAH用量低于12 %时，复合材料的综合力学性能较好；而PP-g-MAH用量为9%~12%时，废旧聚烯烃形成了较为完善的连续相结构，此时复合材料的加工性能和力学性能均较好。

Abstract: Waste polyolefin / wood flour composites were prepared, and the influence of PP-g-MAH and other additives on the mechanical properties and microstructure of the composites was studied. The processing property of the composites containing both PP-g-MAH and EVA was significantly better than that containing EVA alone. When the EVA content was 2% and the PP-g-MAH content was higher than 9%, the composite material had a lower shear torque. When the PP-g-MAH was 9~12%, the recycled polyolefin formed a continuous phase structure, the processing and mechanical properties of the composites were excellent.
