| 摘 要： | 以过硫酸铵为引发剂,采用自由基聚合法,使淀粉与丙烯酸钠和丙烯酸钾进行接枝共聚,制备了一类富钾型淀粉接枝丙烯酸盐缓释肥包膜材料及包膜缓释肥。在氢氧化钾与丙烯酸摩尔比大于3∶20,淀粉与丙烯酸的质量比在1∶6～1∶5时,均可满足缓释肥的释放要求,且包膜材料最大吸水倍率可达408 g/g。

| Abstract: | A series of slow release fertilizers contained potassium were prepared from amylum,acrylic acid,and potassium hydroxide by the method of copolymerization.The optimal molar ratio of potassium hydroxide to acrylic acid was more than 3∶20,while the optimal mass ratio of amylum to acrylic acid was 1∶6~1∶5.The max water absorption amount was 408 g/g. |
