摘要:
以丙烯酸和丙烯酰胺为单体,采用新型水溶液聚合法,制备海藻酸钠改性的膨润土/聚(丙烯酸钠-丙烯酰胺)高吸水性复合材料.采用正交实验,考察交联剂、引发剂、中和度、海藻酸钠、膨润土及单体质量比等因素对吸水倍率的影响.结果表明,当膨润土质量分数为30%时,该高吸水性复合材料仍可吸收自身重量1 200多倍的蒸馏水.傅里叶变换红外光谱(FTIR)与扫描电子显微镜(SEM)分析表明,单体与矿物结合良好.
Abstract:
A superabsorbent composite is synthesized by polymerization and cross linking reaction,with acrylic acid and acrylamide as monomers,with N,N-methylene-bis-acrylamide as cross-linking agent and potassium persulfate as an initiator.Bentonite and sodium alginate were added in reaction solution and reacted with monomer.Regarding water absorption of this material,a study is made on such influencing factors as amount of initiator and cross-linking agent,amount of bentonite and sodium alginate,and neutralization degree,and the mass ratio of acrylic acid to acrylamide.When the amount of bentonite is 30%,the water absorption of this material will surpass 1 200 g·g-1.
