摘要:
针对反相悬浮聚合制备高吸水树脂存在重复性差,吸水倍率低等问题,以环己烷为连续相,山梨糖醇酐油酸酯为悬浮稳定剂,N,N丙烯酰胺为交联剂,过硫酸盐为引发剂,采用反向悬浮乳液聚合法合成聚丙烯酸-丙烯酰胺共聚高吸水树脂.探讨了交联剂浓度、分散剂质量分数、搅拌速度和反应温度等因素对树脂吸液率和粒径的影响,结果表明:当交联剂质量为单体质量的0.105%,分散剂质量为单体质量的6%,单体中和度为70%,油水比为2.0∶1,反应温度为70~74 ℃时,所合成的高吸水树脂粒径为0.1 mm, 最大吸水倍率为584 g/g, 最大吸盐水(质量分数为0.9%的NaCl水溶液)倍率为148 g/g.
Abstract:
To solve the problem of low repeatability and absorbing rate in the inverse suspension polymerization, the poly(acrylic acidacrylamide)superabsorbent copolymer was synthesized through inverse suspension polymerization, using cyclohexane as the continuous phase, span80 as the suspension stabilizer, N,Nmethylene bisacrylamide and persulfate as the corsslinking agent and the initiator, respectively. The effects of crosslinking agent, dispersing agent, the agitation speed and reaction temperature on the water absorbency and particle size of super absorbent resin were studied. The results show that the maximum absorbency of sodium acrylateacrylamide copolymer reaches 584 g/g and 148 g/g in distilled water and in NaCl (0.9%) aqueous solution respectively when the concentrations of crosslinker is 0.105% of the monomer’s, the concentrations of dispersant is 6 % of the monomer’s, the neutralization degree is 70%, the ratio of oil and water is 2.0∶1, the reaction temperature is 70-74 ℃, and the particle size of the resin is 0.1 mm.
