40%乙草胺·扑草净悬乳剂的配方研制

The Formula Development of 40% Acetochlor-prometryn Suspoemulsion

介绍了一种环保型40%乙草胺·扑草净悬乳剂,通过对分散剂、润湿剂、乳化剂、抗冻剂、增稠剂等的筛选,考察了配制的悬乳剂各种控制项目指标,并确定了最佳配方为:乙草胺25%,扑草净15%,MK-63 1.5%,MK-3013 1.5%,MK-203 2%,乙二醇4%,硅酸镁铝1%,黄原胶0.15%,苯甲酸钠0.15%,水余量。结果表明,该悬乳剂配方质量稳定、分解率低,有良好的开发应用前景。

This article introduced an environmental formulation 40% acetecldor - prometryn SE . By the selection of dispersing agent, wetting agent, emulgator, antifreeze agent and thickening agent , and the evaluation of SE, the optimized formulation was comfired.. The best formulation is acetochlor 25% ,prometryn 15%, MK -63 1.5% ,MK -3013 1.5%, MK -203 2%, ethylene glycol 4%, aluminium -magnesium silicate 1%, xanthangum,0.15% ,sodium benzoate 0. 15%, water up to 100%. The result showed that the formulation is good stable, low - decomposed. It has good potential applications.
