摘要
本研究通过对润湿分散剂、增稠剂和防冻剂等助剂的筛选,最终确定了40%丁香·戊哇醇悬浮剂的最佳配方:丁香菌酯原药10.4%、戊唑醇原药31%、SD-208为6%、乙二醇4%、黄原胶7%、有机硅消泡剂1%、去离子水补足。结果表明:该配方制备的悬浮剂平均粒径<3μm,悬浮率95%以上,其它各性能指标也均达到悬浮剂的要求。并通过悬浮剂的Zeta电位值说明了体系具有优良的稳定性。
In this paper, The formula of coumoxystrobin 4-tebuconazole 40% suspension concentrate was optimized by screening up the major formulants including wetting and dispersing agents, thickening agents as well as antifreeze agents. The optimum formula was determined as coumoxystrobin 10. 4%, tebuconazole 31%, SD-208 6%, ethylene glycol 4%, xanthan gum7%, silicone defoamer 1 % and water added to 100%. The results showed that the average particle size of the SC product with the optimum formula was less than 3μm and the suspension rate was over 95%. All the other parameters complied with the requirements for suspension concentrate formulation. And the zeta potential value of the suspension agent indicated excellent stability of the system.
