摘　　要：制备了聚烯烃/木粉微孔复合材料,研究了基体树脂种类、木粉用量、发泡母粒用量等因素对复合材料密度、孔隙率、力学性能和微观结构的影响。结果表明:基体树脂性能对木塑微孔复合材料的拉伸强度影响较大;增加木粉用量,复合材料力学性能下降,密度上升;增加发泡母粒用量,复合材料的孔隙率增大,密度下降,力学性能先升后降;试验范围内,发泡母粒最佳用量约为1%。Polyolefin/wood flour microcellular composite was prepared.The effects of matrix resins,content of wood flour and foaming master batch on density,porosity,mechanical property and microstructure of the composite were studied.The results show that：the property of the composite depends on the property of matrix resin;with the increase of wood flour content,the mechanical property of the composite decreases,the density increases;with the increase of foaming master batch content,the porosity of the composite increases,the density decreases,the mechanical property increases at first and then decreases;the optimum content of foaming master batch is 1% within the experimental range.
