Abstract
The invention discloses a weeding suspending agent which is characterized by comprising 350-650g/L of diflufenican as the active ingredient of an effective body, 25-35g/L of cosolvent, 10-50g/L of wetting agent, 20-60g/L of dispersing agent, 1-5g/L of defoaming agent, 2-5g/L of thickening agent, 1-5g/L of preservative and the balance of water, wherein the total volume of all the components is up to 1000L, and the wetting agent is one or several from methyl phenol formaldehyde resin, polyoxyethylene ether and polyether modified organo-siloxane. The weeding suspending agent has the advantages that no organic solvent is used in the suspending agent, the water is used as the solvent, and therefore, no dust shifting phenomenon is caused in application; the grinding particle size is small, and therefore, the weeding suspending agent is conveniently absorbed by plants, environment pollution is reduced, and the requirement for green agricultural production is met; and the product has the advantages of good stability, capability of antifreezing and preventing corrosion, good weeding effect and the like.
Description
Technical field
The present invention relates to a kind of weeding suspending agent, belong to pesticide production technology field.
The invention still further relates to a kind of preparation method of weeding suspending agent.
Background technology
Diflufenican is weed killer herbicide efficient, low toxicity, is mainly used in the weeding of Wheat and barley field.This product has and suppresses carotenoid, biosynthesis effect, after the medication in the plant carotenoid content descend, cause the weeds Destruction of Chlorophyll, membranolysis and death can be prevented and kill off grass family and broad leaved weed.
At present, the formulation of domestic diflufenican mainly is wetting powder, because wetting powder dust drift in producing and using, has caused environmental pollution and to the infringement of human body, is one of China and even whole world restriction formulation that will not develop.The particle diameter of wetting powder is large in addition, and most medicament can not be absorbed by weeds in spraying process, and is scattering in the farmland, has increased the pollution to environment, does not reach again the herbicidal effect of expection.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.

Cosolvent 25～35g/L; Thickener 2～5g/L;
Wetting agent 10～50g/L; Preservative 1～5g/L;
Dispersant 20～60g/L; Water complements to 1000L.
This weeding suspending agent also comprises antifreeze, and described antifreeze is one or more in ethylene glycol, propane diols, the glycerine.
Described cosolvent is selected from one or more in ethylene glycol, propane diols, the glycerine.
Described defoamer is selected from one or more in organosilicon, dimethyl silicone polymer, the isooctanol.
Described thickener is selected from one or more in urea, magnesium silicate lead, xanthans, the sodium alginate.
Described preservative is selected from one or more in Sodium Benzoate, the Kathon CG.
Described dispersant is one or more in calcium lignosulfonate, alkyl phenolic group polyoxy phosphate, the sodium methylene bis-naphthalene sulfonate.
A kind of preparation method of weeding suspending agent may further comprise the steps:
A, component diflufenican, water, the cosolvent of weeding suspending agent in the claim 1 be added to stir pulping in the batching kettle, slurry is delivered to rubber mill roughly grinds;
B, will roughly grind liquid and enter and carry out fine grinding in the sand mill, and be milled to average grain diameter and after 3 microns, deliver to compounding kettle, and add defoamer, thickener, wetting agent, preservative, dispersant in the ratio of claim 1 and fully stir;
C, sample analysis detect qualified product and are delivered to finished product storage tank, packed products.
Beneficial effect of the present invention: this suspending agent is not with an organic solvent, make solvent with water, in application without the dust drift, the grinding particle diameter is little, be convenient to plant absorbing, reduced the pollution to environment, meet the requirement that green agriculture is produced, and product has good stability, antifreeze anticorrosion, the advantage such as herbicidal effect is good.
