摘　　要：对油菜秸秆粉替代木粉与聚氯乙烯复合制备木塑复合材料进行了研究,在单因素试验基础上通过正交试验初步得到油菜秸秆粉与聚氯乙烯置备木塑复合材料的最佳条件。试验结果表明:经过碱处理的秸秆粉可以增强片材的弯曲强度,但是碱浓度过高反而会降低片材的弯曲强度;当PVC份数为240份、DOP含量为30%、稻壳填料配比3:2和加工温度170℃时,所制得的复合材料性能最佳;经钛酸酯偶联剂处理的改性秸秆粉能增强PVC板材的弯曲强度。By the orthogonal experiment this paper studed the compound method of hot plastic using rape straw powder and PVC. The result showed that straw powder treated with alkali could increase plastic sheet＇s flexural strength, but if alkali concentration was too high ,plastic sheet＇s flexural strength was decreased. The compound material with the best performance could be produced with 67.5% PVC, 30% DOP,3：2 rice hush and staff rate and at 17℃ temperature.The modified straw powder treated with Titanate coupling agent could increase the flexurat strength of PVC sheet.
