Agent, 0%~30% solvent, 30%~98.8% vegetable oil add the above components into mixed kettle, stir evenly, cut with height
It cuts machine to shear 30 minutes to 60 minutes, then material is ground by sand mill, until material particular diameter D50Less than 2 microns to get to can
To be suitble to the pesticide used that oil-suspending agent can be dispersed.
Above-mentioned dispersible oily suspension aids, the tackifier can be white carbon black, bentonite, the one kind or several such as polyvinyl alcohol
Kind.
Above-mentioned dispersible oily suspension aids, it is molten that the solvent can be the aromatic hydrocarbons such as dimethylbenzene, S-150 aromatic solvent naphtha
Or mixtures thereof alcohols such as agent or methanol, ethyl alcohol.
Above-mentioned dispersible oily suspension aids, the vegetable oil can be soybean oil, corn oil, rapeseed oil, esterification soybean
One or more of oil, esterification palm oil, esterification rapeseed oil, Rice oil.
Specific embodiment
For the application method of verifying dispersible oily suspension aids of the invention, applicant is by specific example to further detailed
Describe the bright present invention in detail, but the present invention is by no means limited to the following examples.Percentage is weight percentage in formula, tool
Body embodiment is as follows:
Formula one:
It is calculated in mass percent, under 30 DEG C of magnetic agitations, calcium dodecyl benzene sulfonate 5%, castor oil polyoxy second is added
Alkene ether 15%, polyisobutylene succinic acid sorbitol ester 30%, S-150 aromatic solvent naphtha 50% are mixed evenly to yellowish
Color homogeneous liquid.
Formula two:
