摘  要：
复合高吸水树脂是一种带有亲水基团的高分子聚合物,是近年来广泛研究的新型功能材料。为提高树脂的吸水倍率、吸水后的凝胶强度以及降低生产成本,采用水溶液聚合法,以N,N-亚甲基双丙烯酰胺(NMBA)为交联剂,过硫酸钾(KPS)为引发剂,在丙烯酸(AA)和丙烯酰胺(AM)为单体共聚交联反应的基础上,添加一定比例的葡萄糖和膨润土,制备葡萄糖/膨润土复合高吸水树脂,考察葡萄糖和膨润土的质量比、单体丙烯酸和丙烯酰胺的质量比、交联剂N,N-亚甲基双丙烯酰胺的用量、引发剂过硫酸钾的用量、聚合反应温度及丙烯酸的中和度对复合树脂吸水率的影响。结果表明:当m(葡萄糖):m(膨润土)=1:3、m(AA):m(AM)=3:1、w(引发剂)=0.4%、w(交联剂)=0.08%、AA中和度为65%、反应温度T=75℃时,复合高吸水树脂最大吸水率为985 g/g,最大吸盐水率为114 g/g。

摘  要：
Complex superabsorbent resin was a high molecule polymer with hydrophilic groups. It was widely studied resent years. To increase the absorption rate of water, gel intensity after water absorbing and decrease the manufacturing costs, a superabsorbent resin was synthesized by aqueous solution polymerization with acrylic acid(AA), acrylamide(AM), glucose and bentonite as substrates, N,N-methylene bisacrylamide(NMBA)as crosslinker, and potassium persulfate(KPS)as initiator. The influences of mass ratio of glucose and bentonite, the monomer ratio, the content of crosslinking agent, the amount of initiator, neutralization degree of acrylic acid and reaction temperature were studied.The results showed that the optimal reaction conditions are as follows: the mass ratio of glucose and bentonite 1:3, the mass ratio of acrylic acid to acrylamide 3:1, the amount of initiating agent 0.4%, the amount of crosslinker 0.08%, the neutralization degree of acrylic acid 65%, reaction temperature 75 ℃. Under such conditions, absorbency of the resin in distilled water and Na C1 solution were 985 g/g and 114 g/g, respectively.
