24%嘧肟·氰氟草可分散油悬浮剂的配方研制

Preparation of Pyribenzoxim+Cyhalofop-butyl 24% OD

采用湿法砂磨工艺对24%嘧肟·氰氟草可分散油悬浮剂中的油相载体、乳化剂和结构稳定剂进行了筛选。确定其优化配方为:嘧啶肟草醚4%、氰氟草酯20%、500#2.1%、602 6.3%、OP-106.3%、乳化剂B 6.3%、无水快T 4%、有机膨润土3%、结构稳定剂C 3%、油相载体A 20%,油酸甲酯补足至100%。所制产品悬浮率高,稳定性良好,热贮和低温稳定性合格,且对水稻田稗草、千金子、鸭舌草防除效果良好。

Pyribenzoxim ＋ cyhalofop-butyl 24% OD was prepared by wet grinding technology, and some main adjuvants of the formula such as carrier, emulsifier and structure stabilizer were screened. The optimum formula of pyribenzoxim ＋ cyhalofop-butyl 24% OD was determined as follows： pyribenzoxim 4%, cyhalofop-butyl 20%, 500# 2.1%, 602 6.3%, OP-10 6.3%, emulsifier B 6.3%, sodium diethylhexyl sulfosuccinate 4%, organic bentonite 3%, structure stabilizer C 3%, oil carrier A 20%, methyl oleate adding to 100%. The OD had high suspension rate, good fluidity and stability, and the thermal storage and cold storage stabilities were qualified. It had good control effect on weeds in rice field.
