摘要

用过硫酸盐-铈盐-亚硫酸氢钠（KPSCANNaHSO3）复合引发体系诱发碱处理稻草与丙烯酸接枝共聚，研究了稻草与丙烯酸接枝共聚合成吸水材料的特性，分析了接枝过程的工艺特点。结果表明，碱处理稻草粉可有效降解秸秆中的木质素和半纤维素，提高了纤维素相对含量，改性纤维组织结构，提高接枝反应性能，碱处理后所得的稻草纤维灰分质量分数仅为1.8%；当KPS、CAN、NaHSO3质量比为15∶3∶5时，该复合引发体系协同性较佳；在m（丙烯酸）∶m（稻草）=8∶1、单体中和度70%、交联剂用量为单体质量的1%、反应温度60 ℃、反应时间3 h条件下，合成吸水材料的接枝率可达493%、吸水倍率达350 g/g。

Abstract

Synthesis and characterization of superabsorbent material was studied by grafting copolymerization of rice straw with acrylic acid. The rice straw was first pretreated with alkali, and then grafted with acrylic acid in the presence of complex initiator consisted of persulfate cerium saltNaHSO3. The results showed that lignin and hemicellulose of rice straw was efficiently removed by alkali treatment, and the ash of rice straw was reduced to 1.8%. Meanwhile, the increased relative amount of cellulose and modified fiber tissue structure were found to be benefit for the subsequent graft reactivity. The synergistic effects of the complex initiation system were intensified when the mass ratio of persulfate/cerium salt/NaHSO3 was 15∶3∶5. The grafting ratio and water absorbency of product was 493% and 350 g/g respectively under the conditions of m(acrylic acid)∶m(rice straw)=8∶1, 70% neutralization degree, 1% crosslinking agent dosage and 60℃ for 3 h.
