以杀虫单和甲氰菊酯为有效成分,以起始外观、冷藏外观、热贮外观、稀释稳定性和流动性为标准,通过对不同表面活性剂、助剂、助溶剂、水的配方筛选实验,得到16%杀虫单-甲氰菊酯微乳剂的最佳制剂配方。优化配方为:杀虫单15%,甲氰菊酯1%,助溶剂15%,乳化剂4%～5%。试验结果表明,该复配微乳剂具有贮藏稳定性好、高效安全等特点。
Insecticidal single and fenpropathrin as active ingredients, with the appearance of the beginning, cold appearance, thermal storage appearance, dilution stability and liquidity as the standard, through the different surfactants, additives, cosolvents, water formulations Screening experiments to obtain the best preparation formulation of 16% insecticidal mono-fenpropathrin microemulsion. The optimized formula is: 15% of pest control, 1% of fenpropathrin, 15% of cosolvent and 4% ~ 5% of emulsifier. The test results show that the compound microemulsion has the characteristics of good storage stability, high efficiency and safety.
