摘要: 采用微波辐射引发合成了聚丙烯酸钾(PAA-K)/平菇菌糠新型高吸水树脂,研究了平菇菌糠、引发剂和交联剂相对丙烯酸(AA)的比率以及丙烯酸中和度、微波辐射功率等对高吸水树脂吸水性能的影响,同时采用傅里叶红外光谱仪、元素分析仪、热重分析仪、扫描电子显微镜等仪器分析手段对复合高吸水树脂的分子结构、热稳定性、表面形态及元素分布进行表征。结果表明,在最佳合成条件下,复合高吸水树脂的最大吸液倍率在蒸馏水中为827 g/g,在浓度0.9 %的NaCl溶液(生理盐水)中为87 g/g;在高速离心机转速为6000 r/min下,50 min复合高水树脂的失水率仅为5.2 %。

Abstract: A superabsorbent copolymer of potassium polyacrylate/cultured pleurotus ostreatus was synthesized with microwave radiation heating. The influence of initiator, crosslinker,neutralization degree of AA, and the microwave power on the performance of superabsorbent resin was investigated. The maximum water absorbency of the superabsorbent resin reached 827 g/g in distilled water and 87 g/g in 0.9 % NaCl solutionThe structure, thermal stability, morphology, and element distribution of the superabsorbent composites were analyzed by Fourier transform infrared spectroscopy, elemental analysis,thermogravimetric analysis, scanning electron microscopy,and energy spectrum analysis. In addition,the water-loss rate was only 5.2 % by centrifugation at a rotatation speed of 6000 r/min in 50 min.
