| 摘 要： | 通过木质素磺酸盐与丙烯酰胺及部分中和的丙烯酸接枝共聚,将木质素磺酸盐引入至高吸水性树脂中,制备了木质素基高吸水性树脂LS-g-P(AA-co-AM),研究了其吸水保水性能.结果表明:被吸收液pH值对LS-g-P(AA-co-AM)树脂吸水性能有很大影响,当被吸收液的pH值在6～7时,树脂的吸水能力最强.树脂具有较好的重...

| Abstract: | Lignin-based superabsorbent resin LS-g-P(AA-co-AM) was prepared through graft copoly-merization of lignosulfonate with acrylamide and partially-neutralized acrylic acid.Water absorbency and water retention of LS-g-P(AA-co-AM) resin were investigated.Experimental results showed that the pH of the absorbed solution has significant influence on the resin's water absorption capacity.The highest water absorption capacity was achieved when the pH was 6-7.LS-g-P(AA-co-AM) resin featured good repeated water absorpt... |
