摘　　要：以废弃的滑子菇菌糠(WMCPN)和丙烯酸(AA)为原料,在微波辐射下合成了复合高吸水性树脂,系统地研究了AA中和度,WMCPN、引发剂过硫酸钾(KPS)和交联剂N,N′-亚甲基双丙烯酰胺(MBA)相对AA的比率以及微波辐射功率(W)对复合树脂材料吸水性能的影响。在最优条件下合成的复合高吸水树脂的吸蒸馏水倍率为1030g/g,吸生理盐水倍率是77g/g。同时,采用扫描电子显微镜(SEM)、红外光谱(FTIR)、热重(TG)对产物结构及表面形貌进行表征,分析表明,复合高吸水树脂是多孔结构且具有良好的热稳定性能。The waste material cultured pholiotanameko(WMCPN)/acrylic acid(AA)composite superabsorbent was prepared via microwave irradiation.The influence of the optimal preparation conditions,such as the weight ratio of WMCPN,initiator,cross-linker to AA,neutralization degree of AA and the microwave power,on the performance of superabsorbent resin were systematacially investigated.The maximum water absorbency of the synthesized superabsorbent resin under the optimal conditions of synthesis was 1030g/g in distilled water and 77g/g in 0.9%NaCl solution,respectively.The structure and morphology were analyzed by SEM,FTIR and TG.The results showed that the products had a porous surface and excellent thermal stability.
