以马铃薯淀粉和丙烯酸为原料、过硫酸钾为引发剂和N,N'-亚甲基双丙烯酰胺为交联剂,部分交联(预交联)后,通过微波辐射完成交联、发泡和干燥,制备泡沫状高吸水树脂,并考察工艺条件对泡沫树脂性能的影响.结果表明:糊化时淀粉与水的质量比1∶10,预交联15 min,微波辐照能量7.5 kJ/g的条件下,得到的泡沫状高吸水树脂吸收化工消防废水的最高吸水倍率可达155.7 g/g,前2min内吸水倍率可达101.6 g/g,与未发泡树脂相比,吸水速率提高了80％,可实现事故现场的化工消防废水快速固定化.%A foam-like super absorbent polymer was prepared through microwave by using potato starch and acrylic acid as material, potassium persulfate as initiator, and N, ./V'-methylene bisacrylamide as crosslinking agent. The steps were pre-crosslinked, cross-linked, foamed, and dried by microwave. The effect of the technological conditions on the foamed resin properties were investigated. Results indicated that, when the mass ratio of starch and water was 1:10,the time of pre-crosslinking was 15 min, and microwave power was 7.5 Kj/g, the maximum amount of absorption of the resin was 155.7 g/g, and 101. 6 g/g in the previous 2 min for chemical industry fire fight wastewater. The wastewater absorption rate increased by 80% compared with the non-foamed resin. Thus,it could be used to achieve high-speed solidification of fire fight wastewater in accident scene.
