Embodiment 1

[0024] Example 1 : 24% tebufenozide anti-spray drift suspension.

[0025] First, 60% of methylated soybean oil, 30% of polyvinyl acetate milk, 5% of urea-formaldehyde resin, 5% of 500# emulsifier, and 5% of 602 emulsifier are mixed and stirred evenly to make a composite anti-spray and drift agent, and then according to the quality Percent tebufenozide 24%, dispersant alkyl polyoxyethylene ether sulfonate 5%, wetting agent nonylphenol polyoxyethylene ether 1%, aluminum magnesium silicate 1.5%, xanthan gum 0.15%, antifreeze Ethylene glycol 5%, defoamer organic silicone 0.4%, water added to 100%. After mixing evenly, sand mill to the qualified particle size. Finally, add the mixed compound anti-spray and drift agent into the sanded tebufenozide suspending agent in an amount of 20%. Finally, it will be homogeneously sheared at a high speed with a thickener, etc. Serve.

[0026] The spraying performance test of the final suspending agent is carried out. The nozzle is used to spr...

Embodiment 2

[0030] Example 2 : 30% quinclorac sustained-release suspension concentrate.

[0031] First, mix and stir 80% of methyl ester tea seed oil, 10% of polyacrylamide, 3% of urea-formaldehyde resin, 6% of 1601# emulsifier, and 4% of 33# emulsifier to make a composite anti-spray drift agent, and then press the quality Percentage 30% quinclorac, quinclorac 30%, dispersant polycarboxylate 4.5%, wetting agent wetting penetrant T 1%, aluminum magnesium silicate 1%, xanthan gum 0.2%, antifreeze Ethylene glycol 5%, defoamer organic silicone 0.4%, water added to 100%. After mixing evenly, sand mill to the qualified particle size, and finally add the mixed compound anti-spray and drift agent in an amount of 20% to the sand-milled quinclorac suspension, and finally, together with the thickener, etc., high-speed homogeneous shear Serve evenly. Carry out spraying performance test according to the method in example 1, control agent is the 30% quinclorac suspension concentrate that does not a...

Embodiment 3

[0034] Example 3 : 15% mesotrione suspension concentrate.

[0035] First, 70% of methyl esterified peanut oil, 20% of epoxy resin modified styrene-acrylic emulsion, 5% of urea-formaldehyde resin 700# emulsifier, and 5% of 1601 emulsifier were mixed and stirred evenly to make a composite anti-spray drift agent, and then Mesotrione 15% by mass, dispersant alkylnaphthalene formaldehyde condensate sulfonate 3.5%, fatty alcohol polyoxyethylene ether 1%, aluminum magnesium silicate 1.7%, xanthan gum 0.1%, antifreeze agent ethylene glycol Alcohol 5%, defoamer organic silicone 0.4%, water added to 100%. After mixing evenly, sand mill to the qualified particle size, and finally add the mixed compound anti-spray and drift agent into the sanded mesotrione suspending agent in an amount of 20%, and finally, together with the thickener, etc., shear at high speed and homogeneously Serve evenly. Spray performance test was carried out according to the method in Example 1, and the control a...

Abstract

The invention relates to a manufacturing technology of a suspending agent with a strong spray-drift prevention function. The suspending agent is prepared from the following components by weight percentage: 1-50% of pesticide active ingredient, 1-60% of a composite anti-drift agent, 1-10% of a dispersing agent, 1-10% of an emulsifying agent, 1-10% of a wetting agent, 0.1-2% of a thickening stabilizer,1-10% of an anti-freezing agent, 0.1-1% of a defoaming agent and the balance being water. The manufacturing technology comprises the following steps of weighing the pesticide active ingredient, the dispersing agent, the wetting agent, the thickening stabilizer,the defoaming agent, the anti-freezing agent and water according to the proportions, feeding the components into an agitated vessel, carrying out shear mixing uniformly, then introducing the mixture into a sand mill to carry out sanding, and then adding the thickening stabilizer and the composite anti-drift agent after qualified grain size is obtained by sanding, and shearing again to form a product. According to the manufacturing technology, the feeding operation is convenient, the process is simple, and safe and environment-friendly effects are achieved.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a technical method for manufacturing a suspending agent with strong resistance to spray drift. Background technique [0002] After spraying pesticides on adjacent fields and drifting (especially some high-efficiency herbicide pesticides), reports of damage to crops have occurred from time to time, which shows that the scourge of pesticide drifting cannot be underestimated. It has been found that the size of the spray droplets directly affects the degree of drift, and the smaller the droplets are, the more likely the off-target movement will occur. Through a large number of field experiments, wind tunnel experiments and predictive mathematical models, the relationship between the size of the surface spray droplets and the off-target drift There was a positive correlation between the possibilities, although the stability of the atmospheric boundary layer, the structure of ...
