摘　　要：保水剂又称高吸水树脂,拥有吸水缓释和肥料控释的能力,对植物的生长有促进作用。保水剂可以由合成聚合物、天然聚合物以及有机和无机物组合合成。保水剂的合成包括物理、化学和杂化键合,主要通过本体聚合法、溶液聚合法、反相悬浮聚合法和辐射聚合法等方法实现。基于此,综述了保水剂的基本概念、性质、作用机理、合成方法及分类,并对其存在的一些问题进行了讨论,指出今后重点是对耐盐性高、可重复利用并能够大量生产的保水剂的研究。Water-retaining agent,also known as superabsorbent polymer,has the ability of absorbing water and controlling the release of fertilizer,and can promote the growth of plants.Water-retaining agents can be synthesized from synthetic polymers,natural polymers,and combinations of organic and inorganic materials.The synthesis of water-retaining agent includes physical,chemical and hybrid bonding,which is mainly realized by bulk polymerization,solution polymerization,inverse suspension polymerization,radiation polymerization and other methods.Based on this,the basic concept,properties,mechanism of action,synthesis methods and classification of water-retaining agents are reviewed,and some existing problems are also discussed in this paper.It is pointed out that the future research focus of water-retaining agent should be on high salt resistance,reusable property and mass production potential.
