摘要

摘要: 采用不同的方法及改性剂处理秸秆纤维, 并对聚丁二酸丁二醇酯(PBS)进行共混改性, 利用热压工艺得到了秸秆纤维/PBS复合材料。研究了水煮和微波处理工艺对秸秆纤维提取量的影响; 研究了苯甲酸等改性剂的种类、添加量对秸秆纤维及秸秆纤维/PBS复合材料性能的影响。采用扫描电子显微镜观察了秸秆纤维处理前后的表面形貌。研究结果表明: 水煮工艺为煮沸30min 2次, 微波处理工艺为微波连续处理15min时为最佳工艺; 对比2种工艺, 微波连续处理15min得到的秸秆纤维比水煮处理后的更为疏松, 比表面积更大, 同时得到的秸秆纤维/PBS复合材料综合性能良好, 并且在硬脂酸质量分数约为3.5%时复合材料的力学性能最优。

Abstract: The straw fibers were treated with different methods and modifiers, and blended with poly(butylene succinate)(PBS) to modify PBS. The straw fiber/PBS composites were prepared by hot-pressing. The effects of boiling processes and microwave treatment on the extraction of the straw fibers, as well as impacts of the type of modifiers and its addition on the straw fiber and properties of the straw fiber/PBS composites were studied. SEM was used to observe the surface morphology of the straw fibers before and after the treatment. The results show that straw fibers boiled for 30min twice, processed continuously by microwave for 15min, respectively get the best specimen. The straw fibers treated in the latter way have a looser property but larger specific surface than that processed the former, and the straw fiber/PBS composites have a better combination property and the best mechanical property under stearic acid condition of about 3.5%.
