摘　　要：采用二辊开炼和压制成型的方法,以马来酸酐接枝聚乙烯(MAPE)、马来酸酐(MAH)和(或)过氧化二异丙苯(DCP)处理木粉制备高密度聚乙烯(HDPE)基木塑复合材料(WPC),考察了几种方法对复合材料力学性能、动态热机械性能及加工性能的影响,并借助扫描电子显微镜(SEM)对复合材料界面进行了形貌分析。结果表明:MAH和DCP共同改性HDPE基WPC,在改善复合材料界面相容性的同时也提高了基体强度,材料综合性能最佳。Wood/HDPE composite was prepared through open-mill milling and press forming, and in the processing,which were modified respectively by maleic anhydride （MAH） grafted PE （MAPE） , MAH, MAH accompany with dicumyl peroxide （DCP） and DCP alone. The mechanical properties,dynamic thermo-mechanical properties and processing characteristic of the composite were investigated,and the interface of the composite was analysed by scanning electronic microscope （ SEM ）. The result showed that MAH add DCP could improve the interracial compatibility and the strength of resin matrix in the same time, the properties of the composite was increased most obviously.
