摘要:
以麦饭石(MDS)、丙烯酸(AA)、2-丙烯酰胺-2-甲基丙磺酸(AMPS) 和羧甲基纤维素(CMC)为原料,采用微波辐射法制备(AA-AMPS-CMC)/MDS高吸水树脂。通过X射线衍射、傅里叶红外光谱、扫描电子显微镜等方法对树脂的结构和形貌进行了表征,并探讨了麦饭石、引发剂、交联剂的质量分数、单体配比、中和度、微波功率对吸水倍率的影响。结果表明:麦饭石和有机单体之间发生了插层复合反应形成高吸水树脂;在最佳合成条件下,树脂在去离子水和生理盐水中的吸水倍率分别为1 169 g/g和 80 g/g,与未加入MDS的树脂相比,吸水倍率分别提高了73%和46%,这表明在体系中适量引入MDS显著提高了树脂的吸水性能;另外在较高温度下,树脂也显示出了良好的保水性能。
Abstract:
Superabsorbent resins were prepared under microwave irradiation with aqueous mixtures of medicinal stone(MDS), acroleic acid, 2-acrylamido-2-methylpropanesulfo-nic acid, and carboxymethyl cellulose. The structure and morphology of the resin were characterized by X-ray diffraction, Fourier infrared spectroscopy and scanning electron microscopy. The effects of the mass fraction of medicinal stone, initiator and crosslinking agent, monomer ratio, neutralization degree and microwave power on water absorption were also investigated. The results show that the superabsorbent resin is prepared via intercalation reaction of medicinal stone with organic monomers. Under the optimized conditions, the water absorption capacity of superabsorbent resin is 1 169 g/g in the deionized water and 80 g/g in normal saline. Compared with the resin without MDS, the water absorption increases by 73% and 46%, respectively, indicating that the appropriate amount of MDS could significantly improve the water absorption of the resin. In addition, the resin also shows good water retention performance at higher temperatures.
