摘要 [目的]研制出各项性能指标合格的50%醚菌酯水分散粒剂。[方法]以制剂悬浮率和崩解性为考察指标,对分散剂、润湿剂、崩解剂及填料进行筛选。[结果]50%醚菌酯水分散粒剂最佳配方(以质量分数计):有效成分质量分数为96%的醚菌酯52%,分散剂GY-D800 6%、助分散剂GY-SN02 10%、润湿剂GY-WS01 3%、崩解剂氯化钠10%、填料为高岭土18%、黏结剂为水。[结论]对制剂性能指标检测,结果表明该产品的崩解分散性好,热贮前悬浮率为91.0%,6次崩解,持久泡沫量为0,热贮(54±2)℃,14 d后悬浮率为83.3%,5次崩解,持久起泡性量为0,有效成分热贮分解率3.2%,各项指标均符合国标要求。 Kresoxim-methyl 50% water dispersible granules was prepared, and the performance index of the formulation was qualified. [Methods] The dispersing agent, wetting agent, disintegrating agent and packing were selected in the method of testing the suspension rate and disintegrative. [Results] Kresoxim-methyl(96% purity) 52%, GY- D800 6% as dispersing agent, GY-SN02 10% as assistant dispering agent, GY-WS01 3% as wetting agent, NaC1 10% as disintegrating agent, kaolin 18% as packing, water as binder were formulated into an optimum formulation ofkresoxim- methyl 50% water dispersible granules. [Conclusions] The result of formulation test showed that the granules had good disintegration and dispersibility. Suspension rate was 91.0%, disintegration was 6 times, lasting foaming amount was 0. After thermal storage at (54±2)℃ for 14 d, the suspension rate was 83.3%, disintegration was 5 times, lasting foaming amount was 0, effective components decomposition rate was 3.2%, all specifications were fit for the requirement of GB.
