采用转相法制备30%氟铃脲·三唑磷微乳剂,简述了其制备理论和制备方法,对配方组分进行了筛选和优化实验,确定了最佳配方组成:氟铃脲2%,三唑磷28%,二甲基甲酰胺+N-甲基吡咯烷酮15%～20%,LQ-500+PA201+PA20220%～30%,水余量。所得制剂在54℃下热贮14d分解率小于5%,透明温度范围为-5～60℃,稀释稳定性及低温稳定性均合格。 The preparation method and preparation method of 30% hexaflumuron triazophos microemulsion were prepared by the method of phase inversion. The components of the formulation were screened and optimized. The optimum formulation was determined as follows: hexaflumuron 2% , Triazophos 28%, dimethylformamide + N-methyl pyrrolidone 15% ~ 20%, LQ-500 + PA201 + PA20220% ~ 30%, water balance. The resulting preparation has a decomposition rate of less than 5% when stored at 54 ° C. for 14 days, and a transparent temperature range of -5 to 60 ° C., both of which are qualified for dilution stability and low-temperature stability.
