采用不同的方法对木粉进行抽提处理,研究木粉抽提物对高密度聚乙烯(PE-HD)/木粉复合材料力学性能的影响,结果表明:木粉抽提物的移出,使木粉颗粒变得较疏松和有孔隙存在,增强了木粉在PE-HD间的分散性,从而提高复合材料的力学性能。其中热水抽提的木粉对复合材料的力学性能提高最显著。 Different methods were used to extract wood flour to study the effect of wood flour extract on the mechanical properties of high density polyethylene (PE-HD) / wood flour composites. The results showed that the removal of wood flour extract Wood flour particles become more loose and porous existence, enhance the dispersibility of wood flour in the PE-HD, thereby enhancing the mechanical properties of composites. Among them, the mechanical properties of the composite extracted by hot water extracted wood flour are the most significant.
