摘要
采用预乳化-乳液聚合法制备了3种农药微胶囊制剂:20%(质量分数)毒死蜱微胶囊、2.5%(质量分数)氯氟氰菊酯微胶囊和1.8%(质量分数)阿维菌素微胶囊;采用激光粒度仪分析了3种微胶囊的粒径均小于1.2μm,且分散均匀;3种制剂的热贮、冷贮稳定性符合农药行业要求;制剂中不含苯及其衍生物助剂,无刺激性气味,可降低对人、畜的接触毒性,是一种环境友好型的农药新剂型。
Three pesticide microcapsule formulations of 20% chlorpyrifos microcapsule,2.5% micro-cyhalothrin and 1.8% abamectin microcapsule were prepared by method of preemulsification-emulsion polymerization in this paper.Particle sizing analysis denoted that they were uniformly dispersed and the droplet size of each kind of microcapsule was less than 1.2 μm.The stability of three microcapsules accorded with requirements of pesticide industry whatever storing conditions.The formulations were free of benzene and aromatic derivative additives,free of irritating odor and low intoxicity to human and animal.The microcapsule suspentions are novel environmentally friendly pesticide formulations.
