Farm chemical microemulsifying assistant composition

Abstract

The present invention relates to efficient general farm chemical microemulsifying assistant composition, which has non-ionic surfactant, anionic surfactant, co-surfactant and proper amount of organic solvent as main components, is prepared through mixing and is used for most of pyrethroid pesticide and microlide pesticide. The pyrethroid pesticide or microlide pesticide may be mixed with the farm chemical microemulsifying assistant composition to form new stable microemulsified pesticide preparation with raised environment compatibility.

Description

technical field [0001] The present invention relates to a non-ionic surfactant, anionic surfactant, co-surfactant and an appropriate amount of organic solvent as the main components, which are used for most pyrethroid pesticides and macrolide pesticides through mixing and processing A high-efficiency general-purpose pesticide microemulsion auxiliary composition for preparation microemulsion. In more detail, pyrethroid pesticides, macrolide pesticide compounds and the pesticide microemulsion additive composition are mixed in a certain proportion, which can spontaneously form a stable and environmentally compatible product that meets the technical requirements of relevant Chinese standards. A new formulation of pesticide microemulsion pesticide. Background technique [0002] Pesticide dosage form is an important means to realize the effective dose delivery of pesticide active ingredients and improve the safety of pesticides. It largely determines the biological activity of pe...

Problems solved by technology

[0003] However, since pesticide microemulsion belongs to a relatively new research field, it began in the 1970s in foreign countries and in the 1990s in my country. Its formation and stability mainly involve the basic theory and experimental technology of colloid and interface chemistry. Pesticide enterprise formulation researchers do not have enough understanding and mastery of basic theories such as the formation of pesticide microemulsions, phase diagram drawing, and stability properties, and cannot effectively characterize the performance of pesticide microemulsions and use them to guide the development of high-efficiency special surfactants, but mainly rely on experience In addition, the types of agricultural surfactants in my country are mainly prepared for traditional preparations such as emulsifiable concentrates. Each manufacturer uses different production formulas, and there are large differences in product performance. In the processing of traditional preparations such as emulsifiable concentrates, there will not be significant differences in quality. But for the microemulsion with very strict formula, its influence is very obvious

As a result, most products currently have problems such as large amount of surfactant, low effective content of preparations, poor product quality, short shelf life, phase inversion, layering, and decomposition of active ingredients of pesticides during storage and transportation, which are the key problems faced by the microemulsion of pesticide preparations. technology

[0004] At present, there is no report at home and abroad for the invention patent of high-efficiency and general-purpose pesticide microemulsion auxiliary composition for multiple pesticide varieties
