摘　　要：以酸处理有机蒙脱土为改性剂,采用水溶液聚合法制备蒙脱土改性丙烯酸基三元共聚高吸水性树脂。在丙烯酸∶丙烯酰胺∶烯丙基磺酸钠单体质量配比为8∶4∶0.5,中和度70%,反应温度75℃,交联剂用量为单体的0.1%,引发剂用量为单体的0.18%和有机蒙脱土用量为单体的4%条件下,所制得树脂的吸水倍率、吸生理盐水倍率和吸人工尿液倍率分别为735.6,58.5,46.6 g/g。The organic montmorillonite was treated with acid as the modifier,and montmorillonite(MMT)modified acrylic-based terpolymerization superabsorbent resin was prepared by aqueous solution polymerization.Under the conditions of acrylic acid(AA)∶acrylamide(AM)∶sodium allyl sulfonate(SAS)monomer mass ratio of 8∶4∶0.5,neutralization degree 70%,reaction temperature 75℃,crosslinker dosage of 0.1%of monomer,initiator dosage of 0.18%of monomer and organic montmorillonite dosage of 4%,the water absorption rate,normal saline absorption rate and artificial urine absorption rate of the prepared resin were 735.6,58.5,46.6 g/g。
