以马铃薯渣为原料、水作溶剂制备了羧甲基马铃薯渣,以N,N′-亚甲基双丙烯酰胺为交联剂,以过硫酸钾和亚硫酸氢钠氧化还原体系作为引发剂,与丙烯酸(盐)在较低温下接枝聚合应合成了高吸水树脂。探究了单体用量、丙烯酸中和度、交联剂用量、氧化还原引发剂用量、总水量对高吸水树脂吸水量的影响;本文还对树脂的吸液能力进行了测定。
Using potato residue as raw material and water as solvent, carboxymethyl potato pomace was prepared. Using N, N’-methylenebisacrylamide as crosslinking agent and potassium persulfate and sodium bisulfite redox system as initiator, With acrylic acid (salt) at a lower temperature graft polymerization should be synthesized superabsorbent. The effects of monomer amount, degree of neutralization of acrylic acid, the amount of cross-linking agent, the amount of redox initiator and the total amount of water on the water absorption capacity of superabsorbent resin were also investigated. The absorbent capacity of resin was also measured.
