摘　　要：麦草原料经碱液喷淋处理后,采用双螺杆挤出机对其进行纤维疏解。以疏解后麦草为原料,利用其溶出木素,并辅以天然淀粉来制备复合材料。研究NaOH用量及淀粉添加量、添加方式对材料力学性能的影响。After the alkaline spray treatment, wheat straw was defibrillated by twin-screw extruder and some lignin was leached out. The bio-composites was prepared by the entire constituents with the lignin, which was supplemented by natural starch. The effect of NaOH concentration, starch addition and adding mode on mechanical properties of bio-composites were studied.
