摘　　要：主要研究了木粉表面甲基化改性和增容剂马来酸酐接枝聚乙烯(PE-g-MAH)对木粉/高密度聚乙烯(HDPE)复合材料力学性能的协同作用。木粉经表面甲基化处理后,与10%PE-g-MAH协同使用,甲基化木粉/PE-g-MAH/HDPE复合材料的拉伸强度、弯曲强度和冲击强度均明显高于未改性木粉/PE-g-MAH/HDPE复合材料,其原因在于在PE-g-MAH的作用下,甲基化木粉在聚合物基体中分布更加均匀,两者的界面作用力更高,即甲基化木粉和PE-g-MAH对提升木粉/HDPE复合材料的力学性能具有良好的协同作用。The synergistic effect of surface methylation modification of wood flour and compatibilizer maleic anhydride grafted polyethylene(PE-g-MAH)on the mechanical properties of wood flour/high-density polyethylene(HDPE)composites was studied.After the wood flour were methylated,the tensile strength,flexural strength and impact strength of methylated wood powder(MWF)/PE-g-MAH/HDPE composites were significantly higher than the unmodified wood flour/PE-g-MAH/HDPE composites after adding 10%PE-g-MAH compatibilizer.The reason was that under the action of PE-g-MAH,the distribution of methylated wood flour in polymer matrix was more uniform,and the interfacial force between them was higher.The methylated wood flour and PE-g-MAH had a good synergistic effect on improving the mechanical properties of wood flour/HDPE composites.
