Technical field
The invention belongs to technical field of pesticide, particularly a kind of farm chemicals diluent and preparation method thereof application.
Background technology
Along with Agricultural Transformation upgrading, agriculture production technology is updated, and new agricultural planting pattern has appearred in the circulation of rural holding.New period agricultural workforce cost constantly increases, and forces widely using of high effect plant protection technology.Along with the raising of people's safety and environmental protection consciousness, for the use cost that ensures food safety, reduces, reduce environmental pollution, need the atomization quality improving agricultural chemicals further, improve effect, reduce the usage amount of medicament, for reaching this object, the modern spray technique such as low capacity, ultra low volume is greatly developed, and particularly low latitude miniature self-service drives an airplane (abbreviation unmanned plane) application at agricultural plant protection technical elements, increases every year with the promotion rate of more than 1,000 ten thousand mu.
But modern low capacity, ultra low volume technology need specific plant equipment and special Pesticide use formulation.Be applicable to the unmanned plane low capacity of high efficiency at present, the agricultural chemicals of ultra low volume, foliage fertilizer product are few, registration is exclusively used in low capacity, the product of ultra low volume spraying does not catch up with development speed far away.In existing commercially available agricultural chemicals, foliage fertilizer product, 99% all uses for routine spraying, is directly used in ultra low volume spraying and there are problems:
As large in crossed highly diluted difficulty due to working concentration, the problem such as crystallization, precipitation easily occur, solvent is volatile, droplet is uneven.The content of the commercially available most medicament design of registration is all very high, and need to carry out dilution and use, conventional dilution multiple designs mostly more than 1000 times, and is dilute with water.And low capacity, ultra low volume spraying mu amount of liquid medicine are 500g or less, only need diluting several times to tens times, concentration dilute with water high be like this easy to occur that precipitation, flocculation, crystallization, breakdown of emulsion, viscosity are excessive, the foam too much not easily phenomenon such as froth breaking.And the generation of these phenomenons, easily there is layering, cause control efficiency poor, easily cause blocking sprayer in dilution poor stability when making operation, the accidents such as poisoning occur.
For another example the solvent aromatic hydrocarbon solvent used when conventional products is produced and vegetable oil solvent, and these solvents are easy to volatilization, and droplet is diminished, sedimentation is slow, easily drifts about.Wherein, the low capacity such as biodiesel solvent oil, heavy aromatics, two wires oil, third fractional oil conventional at present, ultra low volume spraying retarder thinner complicated component, impurity are many, containing benezene toxic solvent, very easily contaminated environment, not environmentally.
Just in existing agricultural chemicals dilution and thinner there is above-mentioned easy generations and block shower nozzle, drift, easily produce the problems such as poisoning, control efficiency are poor, contaminated environment, be therefore necessary to research and develop a kind of environmental protection, thinner that compatibility is good, stable, efficient, general.
Summary of the invention
The object of the invention is to the above-mentioned deficiency overcoming prior art, a kind of farm chemicals diluent and preparation method thereof is provided, existingly adopt that dilute with water easily causes agricultural chemicals to precipitate, flocculates to overcome, crystallization, volatile, drift dilution poor stability when making operation, easy generation layering, cause blocking sprayer, poisoning occurs, and use the deficiencies such as traditional low capacity, ultra low volume thinner toxicity are large, smell large, easy damaged crop, contaminated environment.
In the application providing farm chemicals diluent of the present invention, the large contaminated environment of toxicity is there is and easily makes by technical problems such as the pesticide solution system after diluting are unstable in another object of the present invention to solve existing farm chemicals diluent.
In order to realize foregoing invention object, technical scheme of the present invention is as follows:
A kind of farm chemicals diluent, described farm chemicals diluent is made up of the component of following mass percent: hydrophilic solvent 40% ~ 90%, surfactant 1% ~ 10%, humectant 1% ~ 10% and water 0 ~ 50%.
And a kind of preparation method of farm chemicals diluent, comprises the steps:
Each component is taken respectively: hydrophilic solvent 40% ~ 90%, surfactant 1% ~ 10%, humectant 1% ~ 10% and water 0 ~ 50% according to the component ratio of following mass percent;
The each component taken is carried out mixing treatment.
And, farm chemicals diluent of the present invention for diluting agricultural chemicals and/or foliage fertilizer.
Compared with prior art, the beneficial effect that the present invention produces is:
Above-mentioned farm chemicals diluent adopts hydrophilic solvent to be base solvent, such that farm chemicals diluent of the present invention not only dissolves each other completely with water, proportion is greater than 1, and has higher solubility to most of agricultural chemicals and foliage fertilizer, and boiling point is high, safety.On this basis, make, by the agricultural chemicals that dilutes or foliage fertilizer solution, be there is high stability by the synergistic effect of surfactant and humectant, can not precipitate more than 1 hour, crystallization, flocculation, the phenomenon such as blocking sprayer.In addition, farm chemicals diluent of the present invention by the acting in conjunction of contained component, it is had advantages such as moisturizing, anti-volatilization, anti-drift, droplet sedimentation are fast, epigranular, good stability.Meanwhile, farm chemicals diluent aromatic-free solvent of the present invention, environmental protection low to person poultry toxicity, flash-point are high, use safety.
