Problems solved by technology

[0003] However, the current microemulsion products often have problems such as stratification, crystallization, turbidity, and flocs in the market, especially in the north of -20 ° C, such as Heilongjiang, Inner Mongolia and other regions, there will also be freezing phenomena, which greatly affects Influenced the development of this dosage form in the field of pesticide technology
In addition, the organic solvents added in the microemulsion--stupid solvents such as toluene, xylene and benzene, etc., have serious environmental pollution.
At the same time, in the field of insecticides in microemulsions, such as organophosphorus pesticides, pyrethroid pesticides, carbamate pesticides, etc., there will also be a prominent problem of high decomposition rate

Abstract

The invention discloses a microemulsion insecticide which comprises 2.5-40% of crude insecticide, 5-40% of methanol, 5-10% of dimethylformamide, 1% of tri-butyl-phosphate, 4-6% of tristyrylphenol polyoxyethylene polyoxypropylene ether, 4-6% of phenethyl isopropylphenol polyoxyethylene ether, 4-6% of nonylphenol polyoxyethylene ether, 10% of white sugar and the balance of water. The microemulsion insecticide has the advantages of wide scope of application, stable dosage form, less than 1% of decomposition rate, stability higher than missible oil, obvious synergism, insecticidal effect increased by 30%, simple formulation and convenience for production.

Description

technical field [0001] The invention relates to an insecticide, in particular to a microemulsion insecticide and a production process thereof, belonging to the field of microemulsion insecticides. Background technique [0002] Microemulsion is composed of liquid pesticides, surfactants, water, stabilizers, etc. It is a thermodynamically stable dispersion system over time. It mainly uses water as the medium and contains no or little organic solvents. Therefore, it is non-flammable and non-explosive. Safe, less environmental pollution, saving a lot of organic solvents; the dispersion of pesticides is extremely high, reaching the degree of miniaturization, the pesticide particles are generally 0.1-0.01 microns, and the appearance is similar to transparent or slightly transparent liquid; good dispersion in water, penetration into the target body Strong, good adhesion. [0003] However, the current microemulsion products in the market often have problems such as stratification, ...
