摘　　要：通过水溶液聚合法,以过硫酸盐为引发剂,N,N 亚甲基以丙酰胺为交联剂,添加不同含量的硅藻土,合成高吸水性树脂.并讨论了交联剂、引发剂、硅藻土等聚合条件对复合材料吸水性能的影响,制备出的材料具有较高的吸水性能和保水性,在降低产品生产成本以及提高材料综合性能方面具有使用价值.With potassium sulfate as initiator, N,N-methylenebisacrylamide as cross-linking agent, and adding diatomite of different contents, the high water-absorbent resin of cross-linked polyacrylamide was synthesized by solution polymerization. The influences of polymerization conditions such as the amount of cross-linking agent, initiator and diatomite on the water absorbency had been studied. It is significant for reducing the productive cost and improving the comprehensive property of the super-absorbent composite.
