摘　　要：炼油催化剂厂在生产过程中每年要排除大量的滤渣,对滤渣成分进行了分析,其中SiO2含量为60%左右,Al2O3含量为10%左右,重金属含量不超过土壤环境质量标准值(GB15618-95)。以丙烯酸(AA)、丙烯酰胺(AM)和催化剂厂滤渣等为主要原料,采用水溶液聚合法制备出了滤渣/P(AA-AM)高吸水复合材料,考察了引发剂用量、交联剂用量、单体中和度及滤渣用量对复合材料吸液倍率的影响。结果表明,当中和度为80%,滤渣、引发剂和交联剂用量分别为丙烯酸单体质量的25%、1.0%和0.04%时所制得复合材料吸蒸馏水、自来水和0.9%NaCl达到了1093.2g/g、323.4g/g和74.39g/g。复合材料在25℃下干燥10d,还保持50%的吸水量,在70℃下干燥10h吸水凝胶还可以保持40%的吸水量,表明复合材料具有良好的保水性能。Catalyst factory affiliated to an oil refinery generates tens and thousands tons of waste filter residue each year,causing the environmental problem that are difficult to handle. This paper seeks for recovery of the residue by a new synthesis process which involves water solution polymerization with acrylic acid,acrylamide and the residue itself,making super-absorbent composite,a new material. Thus an experimental study was conducted investigating factors that affect water absorbency of the material,resulti...
