摘要
采用N,N-亚甲基双丙烯酰胺为交联剂,以过硫酸钾为引发剂,利用水溶液聚合法制备了淀粉接枝丙烯酰胺/沸石高吸水性复合材料,研究了淀粉与单体的配比、沸石添加量、交联剂用量、引发剂用量及中和度对吸水倍率的影响,探讨了复合材料的保水性,用红外光谱表征复合材料的结构。结果表明:沸石在聚合物中能较好分散,复合材料吸自来水倍率达365g/g,对生理盐水溶液的吸水倍率达67g/g,其保水性能良好。
Using N,N-methylene-bis-acrylamide as a crosslinker and potassium sulfate as an initiator,a super-absorbent composite of starch graft acrylamide/zeolite is prepared by polymerization and crosslinking reactions.Several major factors influencing these reactions,such as the ratio of amylum to monomer,the dosage of the initiatorand crosslinker,the amount of added zeolite and the neutralization degree were also researched.The water retention property of the composite material was explored.The structure of the composite material has been characterized by IR（Infrared Spectra）.The results showed that zeolite is well dispersed in the composit material.The resin can absorb 365g/g pure water and 67g/g physiological solution（ω（NaCl）≈0.9%）.
