以丙烯酸(AA)、丙烯酰胺(AM)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)为原料,通过反相悬浮法制得具有阳离子、阴离子、非离子单体和高岭土复合的耐盐型高吸水树脂。选用环己烷作为油相,过硫酸钾为引发剂,N,N-亚甲基双丙烯酰胺为交联剂,Span 60为悬浮剂,研究了丙烯酸中和度、高岭土用量、DMC用量、引发剂用量、交联剂用量、反应温度对树脂吸液性能的影响。并用红外光谱和扫描电镜对其结构进行了表征。在最佳工艺条件下,耐盐型吸水树脂对蒸馏水和生理盐水的吸液率分别为1 827 g/g和146 g/g。
Using acrylic acid (AA), acrylamide (AM) and methacryloyloxyethyltrimethylammonium chloride (DMC) as raw materials, the compound with cationic, anionic, nonionic monomer and kaolin Salt-tolerant superabsorbent. Cyclohexane as oil phase, potassium persulfate as initiator, N, N-methylenebisacrylamide as crosslinking agent, Span 60 as suspending agent, the degree of neutralization of acrylic acid, the amount of kaolin, the amount of DMC, The effects of dosage, crosslinking agent dosage and reaction temperature on the liquid absorption capacity of resin. Its structure was characterized by infrared spectroscopy and scanning electron microscopy. Under optimum conditions, the water absorption rate of salt-tolerant water-absorbing resin to distilled water and physiological saline were 1 827 g / g and 146 g / g, respectively.
