Abstract
The invention relates to a pyribenzoxim oil suspending agent and a preparation method thereof. The pyribenzoxim oil suspending agent comprises the following components in percentage by weight: 1-30% of pyribenzoxim, 5-15% of penetrant, 5-20% of wetting dispersant, 1-5% of thickener and the balance of dispersion medium. The preparation method comprises the following steps of: preparing the raw materials according to the weight percentage; adding the raw materials into a blending kettle and stirring until the materials are sufficiently and uniformly mixed; adding the mixture into a rapid-flow type mixer, and performing shear dispersion until solid particles are invisible; transferring the material into a sand mill, and performing three-level sanding until the average particle size of the material is 2-3 microns; and transferring the material into a high-shear mixing kettle, adding the penetrant, and performing shear mixing for 30-40 minutes to obtain the pyribenzoxim oil suspending agent. Compared with the missible oil, the aromatic hydrocarbon solvent is replaced by vegetable oil or methyl-esterified vegetable oil, thus little environmental pollution is caused; and moreover, a perfect synergistic effect is realized, the weed prevention effect can be greatly improved, and the dosage and prevention cost are reduced.
Description
Technical field
The invention belongs to the agricultural herbicide technical field, particularly a kind of pyribenzoxim oil-suspending agent and preparation method thereof.

Said thickener is selected from the mixture of one or both compositions in organobentonite or the fume colloidal silica.
Said dispersion medium is selected from the mixture of one or more compositions in soybean oil, corn oil, rapeseed oil, cottonseed oil, palm oil, esterification soybean oil, esterification corn oil, esterification rapeseed oil, esterification cottonseed oil or the esterification palm oil.
Above-mentioned said material all can be buied through the commercial channel.
The preparation method of pyribenzoxim oil-suspending agent may further comprise the steps:
1, prepare raw material:
The following percentage by weight that accounts for total raw material weight by each raw material is prepared raw material: pyribenzoxim, 1%～30%; Bleeding agent, 5%～15%; Wetting dispersing agent, 5%～20%; Thickener, 1%～5%; Dispersion medium, surplus.
2, in the still that is mixed, add the raw material of getting ready in the step 1, be stirred to material and fully mix.
3, the mixture with gained in the step 2 adds in the prompt streaming mixer, shears to be dispersed to and does not have visible solid particle.
4, will be transferred in the sand mill through the material after step 3 is handled, through three grades of sand millings, to the average grain diameter of material at 2～3 microns.
5, the material with step 4 gained is transferred in the high shear mixing still, adds bleeding agent, shears and makes the pyribenzoxim oil-suspending agent after 30～40 minutes.
With indexs such as the above-mentioned pyribenzoxim oil-suspending agent check emulsifying dispersivity that makes, dilution stability, qualified back packing.
Beneficial effect of the present invention is:
1, compare with missible oil, oil-suspending agent uses vegetable oil or methylated vegetable oil to substitute aromatic hydrocarbon solvents such as benzene, toluene and xylol, and environmental pollution is little;
2, have fabulous synergistic effect, can promote the control of weeds effect greatly, reduce dosage and control cost.
