中文摘要：
对钠基蒙脱土进行有机化改性处理,并把改性后的蒙脱土分散于丙烯酸钠水相中,用反相悬浮聚合法合成出蒙脱土插层聚丙烯酸钠高吸水性树脂.用IR、XRD等进行结构分析、表征,结果表明：合成树脂的网络内含有蒙脱土,且充分撑开,纳米量级均匀分散在聚合物基体中;加入10%改性蒙脱土,能显著提高树脂的凝胶强度、保水能力和吸水速度等性能.
英文摘要：
Using montmorillonite modified organically as host and acrylic acid as guest, the super absorbent polymers of PAA / MMT are prepared by inverse suspension polymerization and compared with pure PAA samples. XRD and IR studies show that the interlayer distance of the MMT fully dispersed in polymer is over 4.66 nm and the PAA / MMT SAP are nanocomposites. For PAA / MMT SAP with 10% clay, the gel strength is 3.6 times as high as that of the pure PAA samples. The important properties of the absorption speed and the retention capacity are also largely improved.
