摘　　要：在引发剂(APS)和交联剂(MBA)的作用下,以丙烯酸、腐植酸(HA)和斜发沸石粉作为合成原料以水溶液聚合法制备了一种新型高吸水聚合物。并采用傅里叶红外光谱(FTIR)、热重分析(TGA)和扫描电镜(SEM)对高吸水性聚合物进行了表征。在最佳合成条件下,测定了该聚合物重复使用性能和在盐溶液中的溶胀能力。结果表明,最佳工艺条件下合成的高吸水性聚合物在蒸馏水中吸水倍率为2076.58 g/g,在0.9%(质量分数)NaCl溶液中吸水倍率为132.43 g/g。在循环使用10次后,聚合物仍保持1007 g/g的吸水倍率。此外,还对高吸水聚合物的合成机理进行了分析。Under the action of initiator(APS)and crosslinking agent(MBA),a new type of superabsorbent polymer was successfully prepared by polymerization of acrylic acid,humic acid(HA)and clinoptilolite powder in aqueous solution.The superabsorbent polymer was characterized by Fourier transform infrared spectroscopy(FTIR),thermogravimetric analysis(TGA),and scanning electron microscopy(SEM).Reusability of the polymer and swelling capacity in salt solution was determined for the polymer synthesized under the optimal synthesis conditions.The results show the water absorption of the optimally synthesized superabsorbent polymer is 2076.58 g/g in distilled water and 132.43 g/g in 0.9%sodium chloride solution.After being recycled ten times,the polymer still retains 1007 g/g of water absorption.In addition,the synthesis mechanism of the superabsorbent polymer was also analyzed.
