摘 要: 通过不同溶剂、乳化剂、防冻剂的配方筛选试验,得到优化配方为高效氯氟氰菊酯原药2.6%、溶剂7%、乳化剂14%、防冻剂5%、余量为水的2.5%高效氯氟氰菊酯微乳剂.经热贮稳定性、冷贮稳定性、经时稳定性等测定,所配制的2.5%高效氯氟氰菊酯微乳剂的pH值、自发分散性、稀释稳定性、浊点等各项质量指标合格. The composition and preparation of 2.5% lambda-cyhalothrin microemulsion were introduced.After a serious of selection experiments of different solvents,emulsifiers,antifreeze and water,the results showed that the optimum formulation are as follows lambda-cyhalothrin 2.6%,solvent 7%,emulsifier 14%,antifreeze 5% water.The physico-chemical property was detected after high and low temperature storage.The results showed that all physico-chemical properties of lambda-cyhalothrin microemulsion were well tally with the national standards.
