Plastic-wood composite materials were prepared from wood flour, PP, HDPE and LDPE and their mechanical properties were compared.
采用木粉分别与聚丙烯（PP）、HDPE、低密度聚乙烯（LDPE）制备了塑木复合材料，并对其性能进行比较。
The results showed that PP/LDPE has high-ratio of foaming , the surface of foamed sheet was smooth and has good overall properties.
结果表明：PP／LDPE共混体系的发泡倍率较高，发泡片材表面光滑，气孔细密，具有较好的综合性能。
