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。
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 content of cotton bast; however the flexure strength was the best when moisture content was 40%.
