摘　　要：以粉煤灰、丙烯酸、丙烯酰胺为原料,采用超声辅助水溶液聚合法制备保水材料.用SEM对其进行结构表征,考察制备条件对保水材料吸水性能的影响.结果表明:粉煤灰与有机相聚合良好,且在聚合物中有效分散.当粉煤灰添加量为丙烯酸单体质量的20%,引发剂用量为0.01%,交联剂用量为0.03%,丙烯酰胺用量为20%,中和度为0.7时,复合材料吸水率达203 g/g.Water-retaining materials were prepared from fly ash,acrylic acid and acrylamide by ultrasound-assisted aqueous solution polymerization.Structure of the materials was characterized by SEM,and the influence of the preparation conditions on the water absorption was studied.The results show that fly ash is well polymerized with the organic phase and effectively dispersed in the polymer.When the fly ash is 20%of the monomer mass of the acrylic acid,the inducer is 0.01%,the crosslinker is 0.03%,the acrylic amine is 20%and the neutralization degree is 0.7,the composite material has a water absorption rate of 203 g/g.
