5．7％氟胺氰菊酯水乳剂的研制

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。

Preparation of tau-fluvalinate 5.7%EW

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 tau-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 antifree...
