| 摘 要： | 以(NH4)2S2O8为引发剂,采用玉米淀粉、丙烯酸、丙烯酰胺多元共聚,合成了耐电解质高吸水性树脂。最佳工艺条件为:引发剂用量(质量百分数)为0.6,单体与淀粉质量比为6∶1,丙烯酰胺与丙烯酸质量比为1∶2.5～1∶3.0,聚合温度50～55℃,反应时间为3h。分析了各种微肥如ZnSO4·7H2O、CuSO4·5H2O、MnSO4·H2O、FeSO4·7H2O、Na2B4O7·10H2O等对高吸水性树脂吸水率的影响,结果表明,多元共聚物提高了产品在实际使用环境中的耐电解质性。

Study on synthesis of anti-electrolytic super absorbent resin and its water absorptivity in solution |
| |
| Abstract: | Anti electrolytic super absorbent resin has been synthesized by the multi graft copolymerization of corn starch to acrylic acid and acrylamide using ammonium persulfate as an initiator. The optimum reaction conditions are as follows:mass ratio of initiator to starch 0.6%, mass ratio of monomer to starch 6∶1, mass ratio of acrylic acid to acrylamide 3.0∶1, temperature 50～55 ℃, reaction time 3 h. The effects of microelement fertilizer such as ZnSO4·7H2O,CuSO4·5H2O,MnSO4·H2O,FeSO4·7H2O, and Na2B4O7·10H2O on water absorptivity of super absorbent resin are analysized. The results showed that the multi graft copolymer is improving anti electrolyte in use. |
