摘　　要：以香蕉茎纤维和丙烯酰胺为原料,过硫酸钾和亚硫酸钠为引发剂,制备了香蕉茎纤维-丙烯酰胺高吸水树脂。研究了酰纤比、反应温度、引发剂用量和交联剂用量对树脂吸水率的影响。香蕉茎纤维-丙烯酰胺高吸水树脂的最佳制备工艺条件为:酰纤比10 g/g、反应温度50℃、引发剂用量1.8%和交联剂用量0.2%。在此条件下,测得所制备的吸水树脂吸水率为458.62 g/g。该研究为香蕉茎的资源化利用提供参考。The preparation process of banana stems fiber-acrylamide superabsorbent was prepared using banana stems fiber and acrylamide as raw materials,potassium persulfate and sodium sulfite as initiators.The effects of the ratio of acrylamide to fiber,reaction temperature,initiator dosage and crosslinker agent dosage on water absorption of resin were studied.The optimal preparation conditions of banana stem fiber-acrylamide superabsorbent were:the ratio of acrylamide to fiber 10 g/g,reaction temperature 50℃,initiator dosage 1.8%and crosslinking agent dosage 0.2%.Under these conditions,the water absorption of the prepared resin was 458.62 g/g.This study provided a reference for the resource utilization of banana stem.
