摘要

以丙烯酸(AA)和羧甲基纤维素(CMC)为原料,采用紫外光引发聚合方法制备了CMC-g-PAA吸水树脂。用红外光谱和扫描电镜对产物进行了表征。研究了AA浓度和CMC含量、反应时间和光引发剂的添加量等因素对该树脂溶胀性能的影响。在优化条件下,所得树脂在蒸馏水和0.9%盐水溶液中的吸液率分别为1720g/g和145g/g。测定了该树脂的吸水速率和土壤中的保水率、研究了盐溶液浓度对树脂吸水率的影响。结果表明,该树脂具有良好吸水保水性能和耐盐性。因此,无论从高效利用天然再生资源,还是从提高水的利用效率角度考虑,研发环境友好的纤维素基保水树脂对农业生产具有重要而现实的意义。
A novel superabsorbent resin was prepared with acrylic acid(AA) and carboxymethyl cellulose(CMC) by ultraviolet(UV) photopolymerization. The samples were further characterized by means of FTIR and SEM. The effects of preparation conditions such as monomer concentration, amount of CMC, exposed time and photoinitiator amount on the absorbency were evaluated. Under the optimum condition, absorbency of the obtained resin 1720g/g in distilled water and 145 g/g in 0.9% Na Cl solution, respectively. The swelling kinetics, salt-resistance, water retention capacity of the CMC-g-PAA superabsorbent were investigated. Results show that the resin has good water absorption, water retention capacity and salt tolerance. Therefore, the development of environmental friendly cellulose-based water-retention resin has important practical significance for agricultural production in consideration of the efficient use of renewable resources and also improve the use efficiency of water.
