对润湿分散剂、增稠剂、防冻剂等进行筛选,得到30%氟啶脲·溴虫腈悬浮剂的最佳制剂配方为:氟啶脲26%,溴虫腈4%,分散剂33SC 3.0%,分散剂NP-10 1.0%,农乳602#1.0%,硅酸镁铝1.5%,黄原胶0.2%,乙二醇4.0%,正辛醇0.2%,SAG-630 0.2%,用水补足至100%.通过湿式超微粉碎法加工工艺制成悬浮剂,制剂分散性良好,悬浮率≥90%,热贮和冷贮稳定性合格.
The formulation of 30% Chlorfluazuron-Chlorfenapyr SC was optimized with main adjuvants like wetting- dispersing agent, thicking agent, anti-freeze agent etc, the optimum composition consisted of Chlorfiuazuron 26%, chlorfenapyr 4%, dispersing agent 4.0%, emulsifier 1.0%, thicking agent 1.7%, anti-freeze agent 4.0%, defoamer 0.4%, up to 100% by water. The formulation was developed with the method of wet grinding. The results showed that the formulation had good dispersion property in water, the suspension rate exceeded 90%, and its physical and chemical properties were not changed significantly when it was stored under cold and heating conditions respectively.
