摘　　要：通过对润湿分散剂、增稠剂和防腐剂等助剂的筛选,最终确定了500 g/L扑草净悬浮剂的最佳配方:扑草净原药47.5%、分散剂SD-811 3.0%、润湿剂SD-206 1.0%、乙二醇4.0%、黄原胶6.0%、硅酸镁铝1.0%、苯甲酸钠0.2%、有机硅消泡剂AFE-3168 0.2%、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 prometryn 500 g/L suspension concentrate was prepared by screening the main adjuvants such as wetting-dispersing agents, thickening agents as well as preservatives. The optimum formula was determined as follows： prometryn 47.5%, dispersant SD-811 3.0%,wetting agent SD-206 1.0%, ethylene glycol 4.0%, xanthan gum 6.0%, magnesium aluminum silicate 1.0%, sodium benzoate 0.2%, organic silicon defoamer AFE-3168 0.2% and water added to 100%. Experimental results showed the average particle diameter of the prometryn 500 g/L suspension concentrate was less than 4μm, the suspension rote was over 95%. All the other pararneters complied with the requirements for suspension concentrate formulation.
