摘　　要：利用三种环境矿物材料(杭锦土,膨润土,硅藻土)合成了吸水树脂,测定了各类吸水树脂的凝胶强度、老化率、吸水倍数和失水速率等性能,并通过矿物粒径分析和三种树脂SEM分析得出:与未添加矿物的树脂相比,三种分别添加了10%的膨润土、杭锦土和硅藻土的吸水树脂具有较高的吸水倍数和较低的失水速率,且与膨润土和硅藻土相比杭锦土合成的吸水树脂具有更大的凝胶强度、更低的老化率、更高的吸水倍数。Water absorbent resins were synthesized by three environmental mineral materials （Hangjin clay, bentonite, diatomite）. Gel strength, aging rate, water absorption and water loss rate of water absorbent resins were determined. In addition, diameters of three mineral materials and SEM of three resins were analyzed. The result indicated that three water absorbent resins containing 10% bentonite, Hangjin clay and diatomite had higher water absorption and lower water loss rate compared with water absorbent resin synthesized without mineral. The water absorbent resin synthesized with Hangjin clay had more gel strength, less aging rate and higher water absorption compared with water absorbent resins synthesized by bentonite and diatomite.
