Description

A kind of halosulfuronmethyl dispersibles oil-suspending agent and preparation method thereof
Technical field
The invention belongs to pesticide field, be specifically related to a kind of halosulfuronmethyl and dispersible oil-suspending agent And preparation method thereof.
Background technology
Halosulfuronmethyl is the inhibitor of acetolactate synthestase, is absorbed by weeds root and leaf, Conducting in plant, weeds i.e. stop growing, rear withered.Because of its rapid metabolization in crop For harmless object, therefore to crop safety.Former medicine is fine powder, and moiety aggregation becomes fritter；Density 1.5 grams every cubic centimetre (20 DEG C)；Fusing point 158-163 DEG C；Dissolubility: water 9mg/L, Normal hexane 0.001g/L, acetone 8.1g/L, toluene 0.256g/L, dichloromethane 6.9g/L.
Dispersible the formulations of pesticide that oil-suspending agent is a kind of great development prospect, stable performance, glue The property is good, notable to target potentiation, decreases dosage and environmental pollution, and chlorine pyrrole is phonetic The grand oil-suspending agent that dispersibles of sulphur is than aqueous suspension agent stable performance, and one-pack type places base for a long time This does not decomposes, and can use with other mixture of herbicides, solve and obtain with other mixture of herbicides The problem that the complex preparation resolution ratio that arrives is high, and without powder during producing and using, to people not Easily cause injury, more more environmentally-friendly than powder.
Summary of the invention
It is an object of the invention to provide a kind of halosulfuronmethyl and dispersible oil-suspending agent and preparation Method, solves the pollution of dust during halosulfuronmethyl uses and has ensured user Healthy, and stable performance, improve drug effect.
Technical scheme: a kind of halosulfuronmethyl dispersibles oil-suspending agent, by following percentage by weight Component composition: halosulfuronmethyl 5%-20%, emulsifying agent 10%-20%, dispersant 1%-3%, Thickening agent 1%-3%, white carbon 1%-3%, surplus is oil solvent.
Described emulsifying agent is selected from NPE, castor oil polyoxyethylene ether, polynary Alcohol fatty acid ester, styryl phenol polyethenoxy ether, fatty polyoxyethylene esters, alkaryl phenol are poly- Two or more mixing in oxygen vinyl Ether phosphate ester.
Emulsifying agent is oleophylic and the compounding composition of hydrophilic emulsifying agent.
Described dispersant is selected from alkylphenol polyoxyethylene formaldehyde condensation products, lignin sulfonic acid Salt, polycarboxylate, naphthalenesulfonate formaldehyde condensation compound, in methoxyl group fatty acyl anilinesulfonic acid The mixing of one or more.
One or both the mixing in organobentonite and xanthan gum of the described thickening agent.
The fineness of described white carbon is crossed 325 mesh standard sieve percent of pass and is more than 98%, and oil suction is more than Equal to 3mL/g.
Described oil solvent selected from turpentine-based vegetable oil, methyl oleate, soybean oil, Oleum Arachidis hypogaeae semen, One or several compositions in mineral oil, solvent naphtha, formicester Petiolus Trachycarpi oil.
A kind of halosulfuronmethyl of the present invention dispersibles the preparation method of oil-suspending agent: at oil solvent Middle addition 5%-20% halosulfuronmethyl, 10%-20% emulsifying agent, 1%-3% dispersant, 1%-3% are white White carbon black, mixing, stirring, stir under high-speed shearing machine 1000-2000 turns the rotating speed of every point and cut Cut, shear 20-30 minute, be ground to D95 less than till 8 microns through sand mill, so The rotating speed that rear addition thickening agent turns every point at cutter 1000-2000 stirs 30-40 minute, surveys D95 less than 8 microns, i.e. prepare that chlorine pyrrole is phonetic dispersibles oil-suspending agent.
Halosulfuronmethyl is used environment-friendly type to help as active component, auxiliary material additive by the present invention Agent (dispersant, emulsifying agent, wetting agent), is made into the stable oil-suspending agent that dispersibles, preparation Reliable and stable, production method is simple；And the oil base flash-point that uses is high, it is ensured that produce, transport Safety, product cost is high, is a kind of broad spectrum type herbicide, instant effect.The present invention solves Halosulfuronmethyl compounds and dispersibles the problem that oil-suspending agent resolution ratio is high, decreases the pollution of environment And the actual bodily harm of user, improve drug effect.
