| 摘 要： | 采用蒸汽爆破对含水率分别为30 %、40 %、50 %的棉秆皮进行预处理，并与高密度聚乙烯（PE-HD）复合制备PE-HD/棉秆皮复合材料，研究了蒸汽爆破、棉秆皮含量、棉秆皮含水率对PE-HD/棉秆皮复合材料力学性能和密度的影响。结果表明，与未经蒸汽爆破处理的PE-HD/棉秆皮复合材料相比，蒸汽爆破预处理后制备的PE-HD/棉秆皮复合材料的力学性能更好；当棉秆皮含量为30 %时，复合材料的综合力学性能最佳；复合材料的拉伸强度随棉秆皮含水率的增加而提高；复合材料的弯曲强度在棉秆皮含水率为40 %时达到最大值。

| Abstract: | Composites were prepared by blending high density polyethylene(PE-HD) with steam-explosion treated cotton bast.The effects of steam-explosion,cotton bast content,and moisture content on the mechanical properties and density of the composites were studied.It showed that steam-explosion improved the mechanical properties of the composites.The mechanical properties of the composites were the best when the content of cotton bast was 30 %.The tensile strength of the composites increased with increasing moisture ... |
