The reagents and other instruments used are not indicated by manufacturers, and are all conventional reagent products which can be obtained commercially.
In order to solve the problems of poor stability and poor universality existing in the existing pesticide, the technical concept provided by the inventor of the invention is as follows: at C16~22Fatty acid amide propyl dimethylamine and C6~10Fatty alcohol-polyoxyethylene ether and polystyrylphenol polyoxyethylene ether with high dispersibility and emulsibility are compounded on the basis of the fatty acid amide propyl dimethylamine to improve the salt resistance, the emulsification effect and the universality of the microemulsion auxiliary agent, so that the stability of the system can be improved when the high-electrolyte pesticide is prepared, and the preparation method is also suitable for preparation of various microemulsion systems. Based on the technical conception, the specific implementation contents of the invention are as follows:
in a first aspect, the embodiments of the present invention provide a microemulsion adjuvant for a high electrolyte pesticide. The microemulsion auxiliary agent consists of C16~22Fatty acid amide propyl dimethylamine, C6~10Fatty acid amide propyl dimethylamine, fatty alcohol polyoxyethylene ether, polystyrylphenol polyoxyethylene ether and a pH regulator.
Wherein, C16~22Fatty acid amide propyl dimethylamine 30-60 wt%, C6~10The weight percentage of the fatty acid amide propyl dimethylamine is 5 percent to 15 percent, and the weight percentage of the fatty alcohol-polyoxyethylene ether is 1 percent to 15 percentThe weight percentage of the polystyrylphenol polyoxyethylene ether is 1-15%. The usage amount of the pH regulator in the specific implementation is determined by the pH value of the microemulsion auxiliary agent, and specifically comprises the following steps: and adjusting the pH value of the microemulsion auxiliary agent to 5-8, wherein the required dosage is the dosage of the pH regulator in the microemulsion auxiliary agent. In practical application, the usage amount of the acetic acid is about 15% -25%.
In the microemulsion auxiliary provided in the embodiment of the application, one is C16~22The fatty acid amide propyl dimethylamine has extremely high salt resistance after being neutralized by a pH regulator, and has good emulsibility in a high electrolyte solution; secondly, due to C6~10The acid amide propyl dimethylamine has shorter carbon chain, has very good salt tolerance after being neutralized by the pH regulator, can increase the mutual solubility of the surfactant which is not high-salt tolerant and other components, has lower interfacial tension, and can be used as cosurfactant. Therefore, the microemulsion auxiliary agent provided by the embodiment of the application can be used for microemulsion preparations compounded by glyphosate, glufosinate and the like and oil-soluble pesticides so as to improve the stability of high-electrolyte pesticides.
In particular, C is preferred16~22The fatty acid amide propyl dimethylamine is cocamidopropyl dimethylamine. Cocamidopropyl dimethylamine: after neutralization with acid, the salt tolerance is very good, and the emulsifying property is good in high electrolyte solution.
In particular, C is preferred6~10The fatty acid amide propyl dimethylamine is caprylic acid amide propyl dimethylamine. Caprylic acid amidopropyl dimethylamine: because of the short carbon chain, the salt tolerance is very good after acid neutralization, the surfactant which is not high-salt tolerant can be solubilized, and the interfacial tension is low, so that the surfactant can be used as a cosurfactant.
The fatty alcohol-polyoxyethylene ether is used as a dispersing agent and a wetting agent, can ensure that the liquid medicine is automatically dispersed when diluted, and can wet a target when the liquid medicine is applied. The polystyrylphenol polyoxyethylene ether is used as a very excellent emulsifier, and hydrophobic groups of the polystyrylphenol polyoxyethylene ether firmly adsorb an oil phase, so that a stable emulsion is easily formed.
In the embodiment, the fatty alcohol-polyoxyethylene ether and the polystyrylphenol polyoxyethylene ether are selected as the nonionic surfactant, and based on the dispersibility and wettability of the fatty alcohol-polyoxyethylene ether, the liquid medicine can be automatically dispersed when diluted, and the liquid medicine can wet a target when applied; the hydrophobic group based on polystyrylphenol polyoxyethylene ether can firmly adsorb an oil phase, and is favorable for forming stable emulsion. Therefore, the microemulsion auxiliary agent provided by the application can be used for ensuring the stability of a pesticide microemulsion system and accelerating the rapid formation of the pesticide microemulsion system during pesticide preparation.
In addition, because fatty alcohol-polyoxyethylene ether and polystyrylphenol polyoxyethylene ether are not resistant to high salt per se, the application is similar to the method for preparing the fatty alcohol-polyoxyethylene ether16~22Fatty acid amide propyl dimethylamine and C6~10After the fatty acid amide propyl dimethylamine is compounded, under the neutralization action of a pH regulator, the fatty acid amide propyl dimethylamine not only has high-salt resistance, but also shows excellent emulsibility in an electrolyte solution, and is easy to form stable microemulsion.
In particular embodiments, the preferred pH adjusting agent is an organic acid, such as acetic acid.
In the embodiment, organic acid is utilized for neutralization, the obtained microemulsion auxiliary agent is an organic phase, the microemulsion auxiliary agent serving as one phase has high stability, and the components do not react after the organic acid is neutralized, so that the microemulsion auxiliary agent provided by the embodiment has high stability and can be stored for a long time.
The microemulsion auxiliary agent provided by the embodiment can be used for microemulsion preparations compounded by glyphosate, glufosinate and the like and oil-soluble pesticides, the problems of unstable storage and reduced efficacy of the pesticides for a long time are solved, and the utilization rate of the pesticides is improved. In addition, the microemulsion auxiliary agent provided by the embodiment can be used for developing high electrolyte pesticides, has high universality, and solves the problem of poor universality of the microemulsion auxiliary agent.
