Abstract
The present invention relates to a kind of environment-protection pesticide solvents comprising the component of following parts by weight：5 ~ 10 parts of vegetable oil, 2 ~ 3 parts of antioxidant, 1 ~ 2 part of chiral pyrrolidine -2,5- diketone, 1 ~ 3 part of surfactant.The invention further relates to the methods for preparing above-mentioned environment-protection pesticide solvent.The environmentally friendly solvent of the present invention is safe to use, environmentally friendly, can also improve the drug effect of pesticide.
Description
Technical field
The present invention relates to pesticide solvent technical fields, and in particular to a kind of environment-protection pesticide solvent.
Background technology
Usually, the formulations of pesticide include mainly missible oil, aqueous emulsion, microemulsion and soluble liquid, in production process
A large amount of such as toluene, dimethylbenzene organic solvent will be used.In recent years, and butanol, octanol, isoamyl alcohol isopolarity occur organic
Solvent.These solvents are increasingly prominent to the accumulation harm caused by environment, ecology and food security in emulsifiable concentrates for agricultural chemicals, simultaneously
Also to the keeping of the production of pesticide, packaging, storage, transport and peasant, using adding many insecurity.
Invention content
The object of the present invention is to provide a kind of environmental-friendly, safe to use environment-protection pesticide solvents.
The present invention adopts the following technical scheme that：
A kind of environment-protection pesticide solvent comprising the component of following parts by weight：5 ~ 10 parts of vegetable oil, 2 ~ 3 parts of antioxidant, chirality
1 ~ 2 part of pyrrolidine-2,5-dione, 1 ~ 3 part of surfactant.
Further, the vegetable oil is corn oil and/or soybean oil.
Further, the mass ratio of the corn oil and soybean oil is 4: 1.
Further, the antioxidant is tocopherol or tea polyphenols.
Further, the surfactant is Tween-80.
Further, chiral pyrrolidine -2,5- diketone is maleimide and/or tartrimide.
Preferably, chiral pyrrolidine -2,5- diketone is maleimide and tartrimide, mass ratio 2: 3.
As most preferably, a kind of environment-protection pesticide solvent comprising 8 parts by weight of corn oil, 2 parts by weight of tea polyphenols, apple acyl
0.4 parts by weight of imines, 0.6 parts by weight of tartrimide, Tween-80 are 2 parts by weight.
A method of above-mentioned environment-protection pesticide solvent being prepared, step includes：The each component for weighing the parts by weight, in 35 ~
Stirring is to be sufficiently mixed at 50 DEG C, after natural cooling to obtain the final product.
In preparation method, preferably 40 DEG C of mixing temperature.
The beneficial effects of the present invention are：
（1）Using pure natural plant oil component, it is not only advantageous to dissolving pesticide, is also prevented from the organic solvents pair such as benzene
The injury of environment and operator.
（2）Antioxidant is conducive to prevent the oxidation of natural plants oil component, prevents crude vegetal from changing with air oxidation
Become its solubility property, extends the term of validity of pesticide.
（3）Surfactant selects nonionic surfactant Tween 80, reduces the surface of natural plants oil solvent
Power increases emulsifying effectiveness, solubilization is played to pesticide.
（4）Chiral pyrrolidine -2,5- diketone and natural plants oil component and surfactant are synergistic, are more advantageous to agriculture
The dispersion effect of medicine in a solvent improves pesticide efficacy.
（5）Each component is stirred mixing under thermal condition, is not only able to improve effect of dissolving each other, also advantageously improves table
The emulsifying effectiveness of face activating agent.
Specific implementation mode
The following describes the present invention in detail with reference to examples.The scope of the present invention is not limited to embodiment, this field
Technical staff makes any change in the range of claim limits and also belongs to the scope of protection of the invention.
Embodiment 1
Weigh soybean oil 5kg, 3 kg of tocopherol, 2 kg of maleimide, Tween-80 be 1 kg, by above-mentioned each component in
Stirring is to be sufficiently mixed at 35 DEG C, after natural cooling to obtain the final product.
Embodiment 2
It is 3 kg to weigh corn oil 10kg, 2.5 kg of tea polyphenols, tartrimide 1.5kg, Tween-80, by above-mentioned each group
Divide and stirred to be sufficiently mixed, after natural cooling at 50 DEG C to obtain the final product.
Embodiment 3
Weigh corn oil 8kg, 2 kg of tea polyphenols, maleimide 0.4kg, tartrimide 0.6kg, Tween-80 2
Kg stirs above-mentioned each component to be sufficiently mixed, after natural cooling at 40 DEG C to obtain the final product.
Embodiment 4
It weighs soybean oil 3kg, corn oil 4kg, 2 kg of tea polyphenols, maleimide 0.4kg, tartrimide 0.6kg, spit

Comparative example 1
It is 2 kg to weigh soybean oil 8kg, maleimide 0.4kg, tartrimide 0.6kg, Tween-80, will be above-mentioned each
Component is stirred to be sufficiently mixed, after natural cooling at 40 DEG C to obtain the final product.
Comparative example 2
It is 2 kg to weigh corn oil 8kg, 2 kg of tea polyphenols, Tween-80, and above-mentioned each component is stirred at 40 DEG C with abundant
It mixes, after natural cooling to obtain the final product.
Comparative example 3
It weighs soybean oil 3kg, corn oil 4kg, 2 kg of tea polyphenols, maleimide 0.4kg, tartrimide 0.6kg, spit
Temperature -80 is 2 kg, by above-mentioned each component in room temperature（20℃）Under be stirred to get.
1 product physical and chemical index of effect example（Table 1）
Table 1
As shown in table 1, each physical and chemical index of 1 ~ 4 products obtained therefrom of embodiment is superior to standard value, especially in the control of acid value
In system, even it is measured again after 6 months, the acid value value of embodiment 1 ~ 4 remains unchanged no more than 4 and color is again smaller than 7,
