文章介绍了26%毒死蜱.功夫水乳剂的制备。以起始外观、冷藏[(0±2)℃,7 d]外观、热贮[(54±2)℃,14 d]外观合格和流动性好,有效成分分解率为标准,通过对不同溶助剂、表面活性剂等的配方筛选,得到26%毒死蜱.功夫水乳剂的最佳制剂配方为:毒死蜱24%,功夫2%,高级醇3%,二甲苯11%~12%,乳化剂(农乳602#+605#)7%~8%,水补余。该水乳剂经(54±2)℃贮存14 d,两有效成分的平均分解率均低于4.0%;0~5℃贮存18个月,经时稳定性合格。
The article describes the preparation of 26% chlorpyrifos Kung fu water emulsion. (0 ± 2) ℃, 7 d] appearance, heat storage [(54 ± 2) ℃, 14 d] appearance and fluidity, the decomposition rate of active ingredients as the standard, Additives, surfactants, etc., to get 26% chlorpyrifos.Kuofu water emulsion best preparation formula: chlorpyrifos 24%, Kung Fu 2%, 3% higher alcohol, xylene 11% ~ 12%, emulsifier Agricultural milk 602 # +605 #) 7% ~ 8%, water surplus. The water emulsion was stored at (54 ± 2) ℃ for 14 days. The average decomposition rates of the two active ingredients were all less than 4.0%. The samples were stored for 18 months at 0 ~ 5 ℃, and were stable in time.
