摘　　要：通过模压成型方法对聚氯乙烯/稻壳粉木塑发泡制品进行了研究,分析了稻壳粉的不同填充量、不同处理方法、不同增塑剂用量以及工艺条件对复合材料性能的影响。由研究结果可知:稻壳粉含量为40份时,制品的综合性能较好;稻壳粉以硅烷偶联剂处理效果较好;随DOP的用量加大,制品的拉伸强度降低,冲击性能和发泡性能提高;实验中,工艺条件的控制是一个极为重要的因素,它直接影响制品的性能。PVC/rice husk powder wood-polymer composite （WPC） foam was studied through press molding. The effects of rice husk powder contents, powder treatment, DOP contents and press molding conditions on the properties of composite material were analyzed. The results showed that when the amount of powder reached 40 phr, the product got good combined properties. Among the various powder treatment methods, silane coupling agent was the best. With the increasing of DOP contents,the tensile strength declined, but the impact strength as well as foaming ability were improved. One of the most important factors in the experiment is molding condition, which influences the properties of the product directly.
