Abstract
The invention belongs to the technical field of pesticide preparation and particularly relates to a weeding pesticide preparation using ionic liquid as cosolvent and a preparation method of the weeding pesticide preparation. The weeding pesticide preparation consists of herbicide, the ionic liquid which is used as herbicide cosolvent, water, booster solvent and emulsifying agent. The weeding pesticide preparation is prepared by adopting the method which comprises the steps of respectively weighing a certain quantity of ionic liquid, water and booster solvent according proportions, mixing the ionic liquid, the water and the booster solvent in a container, ultrasonically oscillating mixed solution till the mixed solution is in an uniform and transparent state, adding a certain quantity of herbicide, then ultrasonically oscillating the mixed solution till the mixed solution is in an even emulsion state, adding the emulsifying agent and finally ultrasonically oscillating the mixed solution till the mixed solution is in an uniform and transparent state. The ionic liquid used by the invention has the characteristics of both liquid and solid, is nonflammable and non-explosive, can replace low-flash-point high-toxicity harmful solvent in pesticide emulsion oil, is safe to transport and is low-toxicity.
Description
Technical field
The invention belongs to technical field of pesticide preparations, particularly a kind of is the weeding pesticidal preparations and preparation method thereof of cosolvent with the ionic liquid.
Background technology
Because China's pesticide original medicine and preparation variety are fewer, the leeway of selecting during use is few, is difficult to bring into play high-drug-effect.China formulations of pesticide constitute unreasonable, and novel form is few and yield poorly, and the processing technology aggregate level is also relatively backward, and old formulation such as missible oil is still occupied an leading position.Need during farm chemical emulsion preparation is produced to use a large amount of organic solvents, its kind mainly contains benzene,toluene,xylene, methyl alcohol, dimethyl formamide etc.The annual consumption of domestic " triphen " up to 200,000 tons ~ 300,000 tons, these solvents have shortcomings such as flash-point is low and inflammable and explosive.These solvents all get into environment in the agricultural chemicals use, not only can cause serious environmental to pollute, and the infringement health, cause biological chronic poisoning, and its problem has caused the extensive concern in the whole world.
The friendly pesticidal preparations of development environment is people's dreams for a long time always.In recent years, the ionic liquid at room temperature of being made up of organic cation and inorganic anion is acknowledged as eco-friendly solvent.It has liquid and solid property concurrently; Nonflammable explosive; Heat endurance is high; Can regulate it to inorganic matter and organic matter solvability through changing anion, cation and side chain, ionic liquid has and premium properties such as is prone to separate with product, be prone to reclaim, can recycle repeatedly, serious environmental, health and the security problems that can avoid the use of conventional organic solvents effectively and caused.
Summary of the invention
Not enough to prior art, the invention provides a kind of is the weeding pesticidal preparations and preparation method thereof of cosolvent with the ionic liquid.
A kind of is that the weeding pesticidal preparations of cosolvent is by weed killer herbicide, constitutes as ionic liquid, water, the cosolvent and the emulsifier of weed killer herbicide cosolvent with the ionic liquid; Wherein the mass fraction of weed killer herbicide, ionic liquid, cosolvent and emulsifier is respectively 1% ~ 13%, 10% ~ 20%, 10% ~ 20% and 5% ~ 7%, and all the other components are water.
Weed killer herbicide is a kind of in Acetochlor, Pendimethalin, chlorfenapyr and the bromacil.
