Abstract
The invention relates to an environment-friendly pesticide solvent. The environment-friendly pesticide solvent is prepared from, by weight, 5-10 parts of plant oil, 2-3 parts of antioxidant, 1-2 parts of chiral pyrrolidine-2,5-diketone and 1-3 parts of a surface active agent. The invention further relates to a preparation method of the environment-friendly pesticide solvent. The environment-friendly pesticide solvent is safe to use, environmentally friendly and capable of improving the effect of the pesticide.
Description
Technical field
The present invention relates to pesticide solvent technical field, be specifically related to a kind of environment-protection pesticide solvent.
Background technology
As a rule, the formulations of pesticide mainly comprise missible oil, aqueous emulsion, microemulsion and soluble liquid, all can use a large amount of as the organic solvent such as toluene, dimethylbenzene in its production process.In recent years, butanols, octanol, isoamyl alcohol polar organic solvent have been there is again.The accumulation harm that these solvents cause environment, ecology and food security at emulsifiable concentrates for agricultural chemicals highlights day by day, also give simultaneously the production of agricultural chemicals, packaging, storage, transport and peasant keeping, use and add many unsafe factors.
Summary of the invention
The object of this invention is to provide a kind of environmental friendliness, the environment-protection pesticide solvent of use safety.
The present invention adopts following technical scheme:
A kind of environment-protection pesticide solvent, it comprises the component of following weight portion: vegetable oil 5 ~ 10 parts, 2 ~ 3 parts, antioxidant, chiral pyrrolidine-2,5-diketone 1 ~ 2 part, 1 ~ 3 part, surfactant.
Further, described vegetable oil is corn oil and/or soybean oil.
Further, the mass ratio of described corn oil and soybean oil is 4: 1.
Further, described antioxidant is vitamin e or Tea Polyphenols.
Further, described surfactant is Tween-80.
Further, described chiral pyrrolidine-2,5-diketone is maleimide and/or tartrimide.
Preferably, described chiral pyrrolidine-2,5-diketone is maleimide and tartrimide, and its mass ratio is 2: 3.
As most preferably, a kind of environment-protection pesticide solvent, it comprises corn oil 8 weight portion, Tea Polyphenols 2 weight portion, maleimide 0.4 weight portion, tartrimide 0.6 weight portion, Tween-80 are 2 weight portions.
Prepare a method for above-mentioned environment-protection pesticide solvent, step comprises: each component taking described weight portion, stirs fully to mix at 35 ~ 50 DEG C, naturally cooling after and get final product.
In preparation method, mixing temperature preferably 40 DEG C.
Beneficial effect of the present invention is:
(1) adopt the vegetable oil composition of pure natural, be not only conducive to dissolving agricultural chemicals, the organic solvents such as benzene can also be prevented the injury of environment and operator.
(2) antioxidant is conducive to the oxidation preventing natural plants oil component, prevents crude vegetal and air oxidation and changes its solubility property, extends the term of validity of agricultural chemicals.
(3) nonionic surfactant Tween 80 selected by surfactant, reduces the surface tension of natural plants oil solvent, increases emulsifying effectiveness, plays solubilization to agricultural chemicals.
(4) chiral pyrrolidine-2,5-diketone and natural plants oil component and surfactant Synergistic, be more conducive to agricultural chemicals dispersion effect in a solvent, improves pesticide efficacy.
(5) under thermal condition, each component is uniformly mixed, not only can improves effect of dissolving each other, also help the emulsifying effectiveness improving surfactant.
