摘　　要：以甘肃会宁地区凹凸棒石黏土(凹土)与丙烯酸(钾)为主要原料,采用溶液聚合法制备凹土/聚丙烯酸(钾)吸水性复合材料,探讨了凹土、交联剂以及引发剂用量对吸水倍率的影响。结果表明,凹土用量为15%～20%、交联剂用量为0.1%、引发剂用量为1.5%～2.0%时,该材料吸蒸馏水和雨水的倍率可达到556.2(g/g)和550.10(g/g)。The superabsorbent composites of attapulgite clay / potassium p olyacrylate have been successfully synthesized by water-solution copolymerization with attapulgite and potassium polyacrylate as principal raw materials. Then the influences of the attapulgite powder, cross-linker and initiator on water absorbency of the composites were discussed.The experiment indicated that, under the conditions： attapulgite clay 15%-20%, cross linker 0.1%, attractant 1.5%- 2.0%, the composite can absorb distilled water and rain water 556.2（g/g）and 550.10（g/g） respectively.
