高分子乳化剂在毒死蜱水乳剂中的应用

Application of polymer emulsifier in chlorpyrifos EW

选用高分子乳化剂,采用反相法制备环境友好型新型毒死蜱水乳剂,并检测其理化性能指标。40%毒死蜱水乳剂的优选配方为:15%S-100#,5%丙三醇,6%高分子乳化剂N-300,3%OP-10,自来水补足。其优选配方在室温、冷贮、热贮下稳定,各项技术指标均符合水乳剂的质量技术指标要求。

An environmental friendly novel formulation of lambda-cyhalothrin EW was prepared by the phase transfer method using polymer emulsifier and evaluated through its physical and chemical perform- ance. The optimum formulation of lambda-cyhalothrin EW consisted of 40% （W/W） chlorpyrifos, 15% S-100#, 5% glycerol,6% polymer emulsifier N-300,3% OP-10,and tap water supply. The results indi- cated that the formulation was stable in room temperature, low temperature and thermal storage, and that the physical and chemical performances met the technical standard of oil-in-water emulsion.
