摘要
采用丙烯酸(AA)、丙烯酰胺(AM)、丙烯酸甲酯(MA)为单体与有机膨润土复合,通过水溶液共聚法制备复合高吸水性树脂。考察丙烯酸中和度、单体配比、引发剂用量、交联剂用量、有机膨润土用量、反应温度对产品吸水倍率的影响。得到了最佳聚合反应条件:丙烯酸中和度75%,单体n(NaAA)∶n(AM)∶n(MA)=8∶2∶1,引发剂用量0.25%,交联剂用量0.03%,反应温度75℃。此条件下制备的高吸水性树脂对蒸馏水和0.9%盐水的吸收倍率分别为850和120 g/g。
The acrylic acid（AA）,acrylamide（AM） and methyl acrylate（MA） were used as monomers to compound with organic bentonite and then the compound high-hydrophilia resin was prepared by water solution copolymerization.The influences of neutralization degree of AA,monomer match,dosages of primer,cross-linking agent and organic bentonite,and reaction temperature on the multiplying factor of the product were investigated.The optimum polymerization condition was obtained as follows： the neutralization degree of AA was 75%,the ratio of monomers n（NaAA）,n（AM） and n（MA） was 8∶2∶1,the primer dosage was 0.25%,the dosage of cross-linking agent was 0.03% and the reaction temperature was 75 ℃.The multiplying factors of high-hydrophilia resin which was prepared under this condition on distilled water and 0.9% salt water were 850 and 120 g/g resp..
