摘　　要：通过对润湿分散剂、增稠剂和密度调节剂等助剂的筛选,最终确定了200 g/L噻虫胺悬浮剂的最佳配方:噻虫胺原药17.8%、SD-816为4.0%、SD-206为2.0%、乙二醇4.0%、硅酸镁铝1.0%、黄原胶8.0%、尿素3.0%、AFE-31680.2%、去离子水补足。试验结果表明:按该配方制备的悬浮剂平均粒径<4μm,悬浮率95%以上,其他各项指标均达到悬浮剂的要求。In this paper, the clothianidin 200 g/L suspension concentrate was prepared by screening the main adjuvants such as wetting-dispersing agents, thickening agents as well as density regulator. The optimum formula was determined as follows： clothianidin17.8%, SD-8164.0%,SD-2062.0%, ethylene glycol 4.0%, magnesium aluminum silicate 1.0%, xanthan gum 8.0%, carbamide 3.0%, AFE-3168 0.2% and water added to 100%. The results show that the average particle diameter of clothianidin 200 g/L suspension concentrate was less than 4 μm, the suspension rate was over 95%. All the other parameters complied with the requirements for suspension concentrate.
