摘要:
[目的]本文旨在探讨9种植物秸秆(花生、油菜、芦苇、大豆、红薯、芝麻、棉花、小麦、水稻秸秆)纤维理化特性的差异,以及其替代天然植物纤维增强木塑复合材料的可行性。[方法]对9种秸秆纤维进行红外光谱(FTIR)和X射线(XRD)分析,并用激光共聚焦显微镜观察其表面微观结构。[结果]9种秸秆纤维红外光谱曲线基本相似;芦苇、油菜和棉花秸秆峰值较高,结晶度较高;芝麻和油菜秸秆抗吸湿性能高于其他7种植物秸秆材料,而小麦和水稻秸秆抗湿性差;9种秸秆纤维微观结构差异较大,芦苇、水稻和小麦秸秆长径比较大。[结论]在9种秸秆纤维中,芦苇和油菜秸秆具有较高的结晶度,小麦、水稻和芦苇秸秆具有较高的长径比以及较低的阻湿性,这些优异的理化特性都为秸秆纤维增强制备木塑复合材料提供了基础。
Abstract:
[Objectives]The paper aimed to explore the differences in physical and chemical properties of nine straw fibers(peanut,rape,reed,soybean,sweet potato,sesame,cotton,wheat,rice straw)and the feasibility of replacing natural plant fiber reinforced wood-plastic composites.[Methods]The infrared spectroscopy(FTIR)and X-ray(XRD)analysis of nine straw fibers were carried out,and the surface microstructure was observed by laser microscope.[Results]The results showed that the infrared spectrum curves of nine straw fibers were basically similar;the peaks of reed straw,rape straw and cotton straw were higher,and the crystallinity was higher;the moisture absorption resistance of sesame straw and rape straw was higher than that of other 7 plant straw materials. Wheat straw and rice straw had poor moisture resistance;the microstructure of nine straw fibers was quite different,and the aspect ratio of reed straw,rice straw and wheat straw was larger.[Conclusions]Among the nine straw fibers,reed and rape straw have higher crystallinity,and wheat,rice and reed straw have higher aspect ratio and lower moisture resistance. These excellent physical and chemical properties provide the basis for the preparation of wood-plastic composites.
