以丙烯酰胺(AM)为单体,N,N-亚甲基双丙烯酰胺(MBA)为交联剂,2-丙烯酰胺基-2甲基丙烷磺酸钠(AMPS-Na)、3-烯丙氧基-2-羟基-1-丙烷磺酸钠盐(HAPS)两种可聚合表面活性剂作为改性剂,与丙烯酰胺共聚,合成了两种改性聚丙烯酰胺吸水性树脂.研究了不同掺量交联剂与改性剂对聚丙烯酰胺吸水性树脂的吸水性能及抗碎化性能的影响.结果表明:提高交联密度可降低聚丙烯酰胺吸水性树脂的吸水倍率,但对其抗碎化能力无改善效果;AMPS改性后的聚丙烯酰胺吸水倍率增大,但其脆性增加,抗碎化能力变差;HAPS改性后的聚丙烯酰胺吸水性能降低不显著,而且韧性和抗碎化能力大大改善.
With AM as raw materials,MBA as crosslinking agent,polymerizable surfactant AMPS-Na and HAPS as a modifier,two kinds of modified acrylamide absorbent resin were synthesized.The effect of different crosslinking agent and modifier on water absorption and fragmentation resistance of polyacrylamide absorbent resin was studied.The results show that increasing the crosslink density can reduce the absorbency,but it does not improve the fragmentation resistance;when polyacrylamide modified by AMPS,its absorbency and fragility increased,but the fragmentation resistance deteriorated;when polyacrylamide modified by HAPS,its absorbency was not significantly reduced,and the toughness and fragmentation resistance greatly improved.
