5.7%氟胺氰菊酯水乳剂的研制

Preparation of tau-fluvalinate 5.7%EW

[目的]确定5.7%氟胺氰菊酯水乳剂的最佳配比。[方法]以溶剂、乳化剂、抗冻剂和增稠剂为影响因子,筛选5.7%氟胺氰菊酯水乳剂的最佳配方,并对其各项性能进行测定。[结果]5.7%氟胺氰菊酯水乳剂最优配方为:以甲苯为溶剂,其占总含量的18%,农乳2201为乳化剂,占总含量的5%;甘油为抗冻剂,占总含量的3%;聚乙二醇400为增稠剂,占总含量的1%。该水乳剂流动性好、不结块、分解率和析水率低,在不同水质中分散性好,符合水乳剂生产的要求。它加工工艺简单,成本低廉,质量可靠,具有良好的开发利用前景。[结论]该研究为5.7%氟胺氰菊酯水乳剂的开发应用奠定了基础。

[ Objective ] The aim was to determine the optimum proportion of tau-fluvalinate 5.7% EW. [ Method ] With solvent, emulsifier, cryoprotectant, thickener as influencing factors, the optimum formula of tau-fluvalinate 5.7% EW was screened and each performance was determined. [ Result] The optimum formula of tan-fluvalinate 5.7% EW was as follows： toluene was taken as cryoprotectant, which accounted for 18% of total content ; Nongru 2201 was taken as emulsifier, which accounted for 5% of total content ; glycerin was taken as antifreeze, which accounted for 3% of total content; polyethylene glycol 400 was taken as thickener, which accounted for 1% of total content. The emulsion in wate had some advantages such as good fluidity, no caking, low decomposition rate, low syneresis rate and good dispersion in different water, which met the demand of emulsion in wate production. The emulsion in wate had simple processing, low price, reliable quality and better development and utilization prospect. [ Conclusion] The research laid the foundation for development and application of tau-fluvalinate 5.7% EW.
