摘要： 以丙烯酸（AA）、丙烯酰胺（AM）和腐殖酸钠（SH）为原料，采用水溶液聚合法合成了聚（丙烯酸—丙烯酰胺）/腐殖酸复合保水剂（PAA-AM/SH），在对各种吸水保水性能测试的基础上，进行了复合保水剂腐殖酸缓释效果的评价。结果表明，PAA-AM/SH复合保水剂不仅具有良好的吸水保水性能，而且具有缓释腐殖酸的功能。

Abstract: In this paper, poly(acylic-acylamide)/sodium humic acid(PAA-AM/SH) superabsorbent composite were synthesized by aqueous solution polymerization based on acrylic acid(AA),acylamide(AM) and sodium humic acid(SH).Water absorbency in aqueous solutions, water retention capability and release property of humic acid of PAA-AM/SH superabsorbent composite were investigated. The results showed that PAA-AM/SH superabsorbent not only have well absorbency and water retention capability, but also have slow release capability of humic acid.
