介绍了农药悬乳剂加工及实验理论依据,对25%丙环唑·多菌灵悬乳剂的配方进行了研究,简述了该剂型的特点、配方选择和贮存稳定性,确定了较佳配方组成:丙环唑11%,多菌灵14%,亚甲基双萘磺酸盐1.5%,苯乙烯苯酚甲醛树脂聚氧乙烯醚磷酸酯盐2.5%,二甲苯5%,十二烷基苯磺酸钙2.5%,苯乙烯基苯酚甲醛树脂聚氧乙烯聚氧丙烯嵌段型聚醚1.5%,壬基酚聚氧乙烯醚改性磷酸酯1.5%,苯乙烯基苯酚聚氧乙烯醚0.5%,硅酸镁铝2%,黄原胶0.5%,乙二醇4%,正辛醇0.5%,水53%,并提出了配制方法及其质量控制指标。实验结果表明,该配方产品悬浮率90%以上,热贮(54℃±2℃,14d)分解率小于5%,产品各项指标符合悬乳剂的要求。
This paper introduced the processing and experimental theoretical basis of pesticide suspoemulsion and studied the formulation of 25% propiconazole and carbendazim suspension emulsions. The characteristics, formula selection and storage stability of the formulation were described briefly. : Propiconazole 11%, Carbendazim 14%, Methylenebisnaphthalene sulfonate 1.5%, Styrene-phenol formaldehyde resin polyoxyethylene ether phosphate 2.5%, Xylene 5%, dodecylbenzenesulfonamide 2.5% of calcium acetate, 1.5% of polyoxyethylene polyoxypropylene block polyether of styryl phenol formaldehyde resin, 1.5% of nonylphenol polyoxyethylene ether phosphate, 0.5% of styrylphenol polyoxyethylene ether, 2% magnesium aluminum silicate, 0.5% xanthan gum, 4% ethylene glycol, 0.5% n-octanol and 53% water, and the preparation methods and quality control indexes are put forward. The experimental results show that the product suspension rate of 90%, heat storage (54 ℃ ± 2 ℃, 14d) decomposition rate of less than 5%, the product of the indicators in line with the requirements of suspoemulsion.
