[目的]探讨制备30%乙氧氟草醚·乙草胺水乳剂产品的方法.[方法]以乙氧氟草醚、乙草胺、乳化剂、溶剂、抗冻剂、消泡剂等为主要原料,对30%乙氧氟草醚·乙草胺水乳剂的制备方法及配方中各组分的最佳含量进行了研究,并对该水乳剂各项性能指标进行了测试评价.[结果]30％乙氧氟草醚·乙草胺水乳剂各组分的最佳配比为:5.0％乙氧氟草醚,25.0％乙草胺.15.0％200#溶剂油,5.2％ S-80乳化剂,2.8％ 602# 乳化剂,4.0％乙二醇,0.3％消泡剂,自来水补足100％.经测试,所得制剂外观、分散性、乳液稳定性、热储析水率及分解率等均符合水乳剂标准.[结论]30％乙氧氟草醚·乙草胺水乳剂加工工艺较简单,性能稳定,质量可靠,且毒性低,贮运及使用安全,与环境相容性好,成本较低,具有较强的市场竞争力.%[ Objective] The technique of the preparation of 30％ oxyfluoffen and acetochlor emulsion in water was researched. [ Method] The method of 30％ oxyfluorfen and acetochlor emulsion, in which the oxyfluoffen, acetochlor, emulsifier, solvent oil, antifreeze and antifoaming agent was used as main raw material, and its formulation was optimized. And the parameter of the formulation was evaluated. [ Results ] The best formulation consisted of 5.0％ oxyfiuorfen, 25.0％ acetochlor, 15.0％ solvent oil 200#, S-80 emulsifier 5.2％, 602# emulsifier 2.8％, ethylene glycol 4.0％, antifoaming agents 0.3％ and water. And the testing result of the formulation indicated the appearance,dispersion, emulsion stability, heat storage rate and decomposition rate of water met the specification required. [ Conclusion] The technique of 30％ oxyfluorfen acetochlor EW was relatively simple, with stable performance, reliable quality, low content of toxicity, easy storage and safety utilization and also with good environmental compatibility, low cost and strong market competitiveness.
