Abstract
The invention relates to a suspending agent aid suitable for pesticide with a high concentration of electrolyte. The aid is mainly composed of the following components in percentage by weight: 10 to 35% of alkyl glucoside, 5 to 10% of sodium dodecyl sulfate, 5 to 20% of disodium ether sulfosuccinate, 5 to 20% of polyoxyethylene ether sulfate, and 15 to 75% of water. The aid has an excellent thickening effect on electrolyte water solutions with different concentrations, can be applied to a compounded pesticide composed of a herbicide (A) and a herbicide (B); wherein the herbicide (A) is one of glyphosate and paraquat dichloride, and the herbicide (B) is one or two of atrazine, diuron, mesotrione, topramezone, penoxsulam, pyraflufen-ethyl, bispyribac-sodium, diflufenzopyr, diflufenican, quinclorac, and oxadiazon; and can guarantee the stability and high suspension rate of a preparation without addition of a thickening agent and a suspending aid.
Description
One, technical field
This patent belongs to agricultural surfactant field, particularly relates to one and is applicable to high concentration electrolyte pesticide herbicide suspending agent auxiliary agent
Two, technical background
Agricultural chemicals suspension agent refers to the preparation be scattered in the particulate homogenous of less than 4 microns by former for solid pesticide medicine in water, is pesticide original medicine and carrier and dispersant, utilizes wet method to carry out the flowable suspended substance of thickness of ultramicro grinding.Be by the former medicine of solid that is insoluble or that be slightly soluble in water by some auxiliary agent, be scattered in more equably in water by ultramicro grinding, the stable liquid-solid state system that form the tiny higher suspension of a kind of particle, can flow.Suspending agent is normally made up of effective ingredient, dispersant, thickener, antiprecipitant, defoamer, antifreezing agent and water etc.The content of effective ingredient is generally 5% ~ 50%.Average grain diameter is generally 3 microns.It is a kind of novel form of pesticide processing.
Suspending agent has following advantage: 1. without dust harzard, to operator and Environmental security; 2. be dispersion medium with water, the inflammable and drug injury problem do not produced by organic solvent; 3. compared with wetting powder, the former medicine selecting different-grain diameter is allowed, to make the biological effect of preparation and physical stability reach best; 4. liquid suspension spreads well in water, directly can make spray liquid and use; 5. than great, packaging volume is little.6. the dispersiveness of suspending agent and plate-out ability all relatively good, suspensibility is high, and the ability sticking to plant corpus surface is stronger, resistance of rainwater washing against, and thus comparatively wetting powder is significantly and also more lasting for drug effect.7. have that particle is little, active surface is large, penetration is strong, drug effect high low without dust, cost when making up a prescription.And have the advantage of wetting powder and missible oil concurrently, can be readily wetted by water, after thin up, suspension is good.
Along with the development of suspending agent, compound suspending agent starts to rise, and the water soluble pesticide composition such as glyphosate salt and paraquat two villaumite is also progressively processed into suspending agent with other mixture of herbicides, to improve the herbicidal effect of weed killer herbicide, but due to glyphosate salt and paraquat two villaumite, solvability is very high in aqueous, and become strong electrolyte state, unexpectedly do not destroy the effect of suspending agent and thickener, and the performance of dispersant can be had a strong impact on, force suspending agent to divide water, solia particle to tie coagulation to form sediment, have a strong impact on stability and the result of use of suspending agent.At present, the Compositional type suspending agent containing glyphosate or paraquat two villaumite circulated on the market, the special thickener of many employings and suspending agent, and the resistance to dipersant of a large amount of use is to improve the stability of preparation, not only cost intensive but also complex manufacturing, be unfavorable for large-scale industrial production.In addition, be limited to electrolyte concentration, the suspending agent of some high-loads still cannot realize suitability for industrialized production.
The present invention is directed to the characteristic of the strong electrolyte pesticide active ingredient such as glyphosate salt, paraquat two villaumite, preferred salt resistant character is good, and combination is optimized to the surfactant that electrolyte solution has a thickening power, make the suspending agent auxiliary agent with multi-efficiencies such as dispersion, wetting, thickening and suspendings, and then achieve the convenience and the operability that utilize the weed killer herbicide such as glyphosate salt or paraquat two villaumite to process the agricultural chemicals suspension agent of different size.
