| 摘 要： | 以膨润土和丙烯酸为原料,采用溶液聚合法合成膨润土/聚丙烯酸钠高保水复合材料的生产工艺,通过单因素试验和正交试验,确定及优化了该保水复合材料吸水性能的配方,即当膨润土添加量为15 g时,引发剂用量0.9 g、交联剂用量0.03 g、中和度70%、单体用量50 mL(加50 mL蒸馏水稀释)、丙烯酰胺用量15 g。在此配方下制取的复合材料吸水率为164.5,吸盐水率为40.5。该设计生产的复合材料与传统高分子吸水树脂相比,具有聚合反应较易控制、抗盐性好、凝胶强度高等优点,可广泛应用于农林园艺、生态环境治理等领域作保水剂。

| Abstract: | Bentonite/polyacrylic acid sodium superabsorbent composite was produced by solution polymerization process using bentonite and propenoic acid.The formula of superabsorbent composite＇s water absorption was determined and optimize by single-factor experiment and orthogonal experiment.That was 15 g bentonite,0.9 g initiator,0.03 g cross linking agent,70% neutralization degree,50 mL monomer dosage（dilute by adding 50 mL distilled water）,15 g acrylamide.Thus,the water absorption rate was 164.5 and salt-water absorbency rate was 40.5.Compared with the traditional polymer injectivity resin,the superabsorbent composite had some advantages,such as easily control polymerization reaction,salt resistance,high gel strength,and so on.The product could be widely used as water-retaining agent in forestry gardening,ecological environment,etc. |
