[目的]研制40%福美双.萎锈灵种子处理悬浮剂。[方法]按拟定配方制备种子处理悬浮剂,对影响其质量的分散剂、成膜剂、防冻剂、增稠剂、消泡剂和染色剂进行筛选。在该基础上得到了最佳配方,并对按最佳配方制备的样品进行了质量测定。[结果]经初步筛选,分别添加2%MorwetIP与3%Morwet D-425、10%成膜剂B、5%乙二醇、0.2%黄原胶和0.3%硅酸铝镁、0.1%SAG-630、0.4%玫瑰精时,制备的样品效果较好。确定的最佳配方为20%福美双、20%萎锈灵、2%MorwetIP、3%Morwet D-425、0.2%黄原胶和0.3%硅酸铝镁、5%乙二醇、10%成膜B、0.4%玫瑰精、水补足100%,研磨时间为2.5 h。该条件下制成的产品各指标均合格。[结论]确定了40%福美双.萎锈灵种子处理悬浮剂的最佳配方。
[Objective] The research aimed to develop 40% thiram-borne seed treatment suspending agent. [Method] The suspending agent was prepared according to the formula of formulation, and the dispersant, film forming agent, antifreeze, thickener, defoaming agent and dyeing agent which affected its quality were screened. On this basis, the best formula was obtained, and the quality of the sample prepared according to the best formula was determined. [Result] After 2% MorwetIP and 3% Morwet D-425, 10% film former B, 5% ethylene glycol, 0.2% xanthan gum and 0.3% magnesium aluminum silicate and 0.1% SAG- 630,0.4% rose essence, the preparation of the sample better. The best formulations determined were 20% thiram, 20% carbendazim, 2% Morwet IP, 3% Morwet D-425, 0.2% xanthan gum and 0.3% magnesium aluminum silicate, 5% ethylene glycol, 10% Film B, 0.4% rose essence, water make up 100%, grinding time is 2.5 h. Under the conditions made of the product indicators are qualified. [Conclusion] The optimal formula of 40% thiram-borneol seed treatment suspending agent was determined.
