农药微乳体系的研究进展

Current Development of Pesticide Microemulsion System

随着人类环境保护意识和自身保护意识的加强,世界农药剂型正朝着水性化、颗粒化、缓释、多功能、省力化和精细化方向发展。农药微乳剂因其良好的环境相容性而受到人们的高度关注。笔者评述了农药微乳剂的制备原理及其微乳体系的流变性质,总结分析了聚合物、表面活性剂、盐以及温度对于农药微乳体系相行为和稳定性的影响,探讨了农药微乳剂的新检测方法,提出了今后需进一步深入研究的问题。

With the ever increasing concerns in environmental protection and human-protection, development of pesticide formulations has been in the direction of water-based, granulized, controlled-release, multi-functional, labor-saving and precisely-application. Great attentions have been paid to the pesticide microemulsion formulation due to its environmental compatibility. The principles of preparing pesticide microemulsion and rheological properties of microemulsion system were reviewed in the paper. Effects of the polymers, surfactants, salts and temperature on phase behavior and stability of pesticide microemulsion system were reviewed. New detection methods of microemulsion were discussed as well. Some remaining problems and issues were put forward to be further studied in the future.
