摘　　要：以玉米淀粉、黄原胶、海藻酸钠、丙烯酸等化合物为主要原料,采用水溶液聚合法合成了一种可降解、吸水抗盐性能优良的绿色环保型农用保水剂,有望解决现有化学保水剂存在的吸盐水率低、降解性能差、环境污染严重等问题。该保水剂在土壤中用量为2%时,对去离子水的吸水性可达875 g,对自来水吸水可达686 g,吸盐水可达205 g,其吸水效果较好;并采用傅立叶变换红外光谱仪、扫描电子显微镜、X射线衍射仪对产物保水剂进行了表征,同时对其分子结构、产物形貌进行了分析探索。The cornstarch,xanthan gum,sodium alginate,acrylic acid and other compounds are used as the main raw materials to synthesize a degradable,green and environment-friendly agricultural water-retaining agent with good water absorption and salt resistance by aqueous solution polymerization.It is expected to solve the problems of low salt absorption,poor degradability and serious environmental pollution of the existing chemical water-retaining agents.When the dosage of this agricultural water-retaining agent in soil is 2%,its deionized water absorption can reach 875 g,tap water absorption can reach 686 g,and salt water absorption can reach 205 g,showing a good water absorption effect;The product is characterized and analyzed by FTIR spectroscopy,scanning electron microscopy and X-ray diffractometer.And the molecular structure and the morphology of product are also studied.
