摘　　要：目的研究木粉含量以及界面相容剂对木粉/PE-HD复合材料力学性能、界面相容性的影响。方法以木粉为填料,与高密度聚乙烯(PE-HD)在双螺杆挤出机上挤出制备复合材料,并测其性能。结果随着木粉添加量的增加,复合材料的力学性能呈现下降趋势;而加相容剂马来酸酐接枝聚乙烯(MAPE)的复合体系,力学性能有了明显改善,并且拉伸强度和弯曲强度随木粉添加量的增加而增加,冲击强度则随之下降。结论MAPE提高了木粉在PE-HD基体中的分散性以及木粉与PE-HD的界面粘结性。Objective： To study effects of woodflour content and compatibilizers on mechanical properties and interfacial compatibility of woodtlour/PE - HD composites. Methods： The composites were extruded in twin - screw extruder with woodflour and PE - HD and all samples＇ mechanical properties was tested. Results： The mechanical properties of compos- ites without compatibilizers decreased with increasing woodflour content. However, this was not consistent with the compos- ites containing maleated polyethylene （ MAPE）, because tensile and flexural strength increased, and impact strength decreased. Conclusion： MAPE can effectively improve the dispersion and interfacial adhesion between woodflour and PE - HD matrix.
