| 中文摘要: |
| 以植物源脂肪酸甲酯为溶剂，以绿色表面活性剂为乳化剂制备环保型高效氯氰菊酯水乳剂，
通过溶剂和表面活性剂的筛选确定了5% 高效氯氰菊酯水乳剂的最优配方：高效氯氰菊酯5%，月桂酸甲酯
14.5%，表面活性剂APG 和AEO3 复配（质量比6：4）总用量为5%，去离子水补足100%。在此基础上，以常
规及市售5% 高效氯氰菊酯水乳剂为对照，通过动态表面张力和动态接触角研究该配方水乳剂的润湿铺展性
能。结果表明，优化的环保型水乳剂500 倍稀释液的动态表面张力和在石蜡膜上的动态接触角随时间下降快，
表现出良好的润湿和铺展性能，有利于农药液滴在植物叶片上的黏着和吸附，从而提高药效。 |
| 英文摘要: |
| Using plant source of fatty acid methyl esters as solvent，green surfactants as emulsifier，
environment-friendly β-Cypermethrin EW was prepared. Optimal formualtion was obtained by screening of the
solvent and surfactant：β-Cypermethrin 5%，laurate methyl 14.5%，APG-AEO3（6∶4 by mass）5%，deionized
water was added to 100%. On this base，the wetting ability of the optimized EW was studied through dynamic surface
tension and dynamic contact angle measurements using ordinary and commercial β-Cypermethrin EWs as comparison
samples. The results showed that the surface tension and the contact angle of the 500-fold dilured sample of the
optimized EW decayed more quickly with time increasing campared with ordinary and commercial β-Cypermethrin
EWs. The excellent wetting and spreading properties made the EW easily adhered and spreaded on the leaf surface to
maximize biological activity. |
