摘　　要：以悬浮率(≥90%)、筛析、分散性、热贮[(54±2)℃,14 d]稳定性为标准,通过对不同润湿分散剂、增稠剂的配方筛选,得到48%甲羧水悬剂。最佳配方为:甲羧原药48%,分散剂木钠3.5%,分散剂NNO 2.0%,润湿剂EFW 2.0%,乳化剂500#2.0%,增稠剂黄原酸胶0.1%,防冻剂乙二醇5.0%,水补足至100%。产品悬浮率≥90%,分散性良好,热贮稳定性合格。The consisting and preparation method of SC for 48% bifenox was introduced. According to the suspension rate（ ≥ 90% ）, screen analysis, dispersity, heat storage stability [ （ 54 ± 2） ℃, 14 d], the screening test recipes of 48 % bifenox were carried out using different wetting dispersants and thickening agents. The optimum composition of bifenox（48% ） was as follows： dispersing agent（5.5% ）, wetting agent （ 2.0% ）, emulsifier （ 2.0% ）, thickening agent （ 0. 1% ）, deicing agent （ 5.0% ） and fill water to 100% were determined, the experimental results of the products showed that suspension rate was over 90%, dispersity was good and heat storge stability was eligible.
