秸秆萃取物的去除增加了秸秆与高密度聚乙烯（HDPE）基体间相的粘附力，同时消除了秸秆/HDPE复合材料的内部缺陷。研究了去除稻草浸出物对稻草/HDPE复合材料的尺寸稳定性（吸水率和热膨胀率）、动态力学性能、蠕变和应力松弛的影响。采用冷水（CW）、热水（HW）和1%碱性溶液（AL）三种方法对稻秆浸出物进行提取。将提取的稻秆和未提取的稻秆与HDPE、马来化聚乙烯（MAPE）和聚乙烯蜡混合，通过挤压法制备复合材料。除AL/HDPE的厚度膨胀和HDPE的热膨胀外，秸秆萃取物的去除显著改善了稻草/HDPE复合材料的尺寸稳定性、动态力学性能以及蠕变和应力松弛。HW/HDPE的综合性能最好。
The removal of rice straw extractives increases the interphase adhesion between rice straw and the high-density polyethylene (HDPE) matrix, while eradicating the inner defects of rice straw/HDPE composites. This study investigated the effect of rice straw extractives removal on the dimensional stability (water uptake and thermal expansion), dynamic mechanical properties, creep, and stress relaxation of rice straw/HDPE composites. Cold water (CW), hot water (HW), and 1% alkaline solution (AL) extraction methods were utilized to remove rice straw extractives. Extracted and unextracted rice straws were mixed with HDPE, maleated polyethylene (MAPE), and Polyethylene wax to prepare composites via extrusion. Removal of rice straw extractives significantly improved the dimensional stability, dynamic mechanical properties, and creep and stress relaxation of rice straw/HDPE composites, with the exception of the thickness swelling of the AL/HDPE and the thermal expansion of the rice straw/HDPE composites. HW/HDPE exhibited the best comprehensive performance.
