【摘要】：對油菜秸稈粉替代木粉與聚氯乙烯復合制備木塑復合材料進行了研究,在單因素試驗基礎上通過正交試驗初步得到油菜秸稈粉與聚氯乙烯置備木塑復合材料的最佳條件。試驗結果表明:經過堿處理的秸稈粉可以增強片材的彎曲強度,但是堿濃度過高反而會降低片材的彎曲強度;當PVC份數(shù)為240份、DOP含量為30%、稻殼填料配比3:2和加工溫度170℃時,所制得的復合材料性能最佳;經鈦酸酯偶聯(lián)劑處理的改性秸稈粉能增強PVC板材的彎曲強度。
[Abstract]:The preparation of wood-plastic composites by replacing wood flour with polyvinyl chloride (PVC) with rape straw powder was studied. On the basis of single factor experiment, the optimum conditions for preparing wood-plastic composites with rape straw powder and PVC were obtained by orthogonal experiment. The results showed that the alkali-treated straw powder could enhance the bending strength of the sheet, but too high alkali concentration would decrease the bending strength of the sheet. When the content of PVC is 240 phr, the content of DOP is 30%, the ratio of rice husk filler is 3:2 and the processing temperature is 170 鈩，
