Abstract
An aquatic emulsion of bifenthrin used as a broad-spectrum insecticide without environmental pollution is prepared from bifenthrin, emulsifier EW7504, organic solvent, antifreezing stabilizer and water proportionally.
Description
Technical field
What the present invention relates to is a kind of broad spectrum pesticide, chemical name is: 3-(2-chloro-3,3,3-trifluoro propene-L-yl)-2,2, dimethyl cyclopropane carboxylic acid-2-methyl-3 methyl-3-phenylbenzyl ester also claims the aqueous emulsion and the preparation technology thereof of Biphenthrin (bifenthrin).
Background technology
Biphenthrin is a kind of widely used pyrethroid insecticides, Biphenthrin product tool is tagged and stomach poison function, knockdown effect is fast, nerve center by the paralysis insect kills off the insect pests, Biphenthrin is difficult for by plant absorbing, is mainly used in the insect of control cotton, vegetables, fruit tree, tea tree etc.Lasting period also long (the control mite class term of validity can for 28 days)
The former medicine of state-owned a few manufacturer production at present, its product is a cream preparation.Cream preparation all mainly adopts aromatic organic solvent to prepare as carrier.Because aromatic organic solvent such as dimethylbenzene, toluene, solvent wet goods are to the pollution problem of environment, relevant environmental protection organization controls the use of this kind solvent, uses no or little the direction that aromatic organic solvent has become trituration.This profit dispersion of aqueous emulsion begins research in the pesticidal preparations exploitation as far back as existing people of initial stage in 19th century, but aqueous emulsion belongs to Unstable Systems, because of its stability is not fine, phenomenons such as layering easily take place, so far in the conventional pesticide preparation variety aqueous emulsion to occupy share minimum.
Summary of the invention
The objective of the invention is in order not use or reduce the usage amount of aromatics organic solvent as far as possible; reduce the organic solvent environmental pollution; protection production, user and other beneficial organisms; a kind of aqueous emulsion of stable Biphenthrin is provided because with water to replace organic solvent, improve produce, transportation, the safety of storing.
Another object of the present invention provides the preparation method of Biphenthrin emulsion in water.
A kind of Biphenthrin emulsion in water, it with the Biphenthrin is effective ingredient, and is formulated by following component in percentage by weight:
Biphenthrin 1～40%
Hydrophilic lipophilic balance HLB is 5～18 emulsifier 1～35%
Organic solvent 1～20%
Stablize antifreezing agent 1～20%
Water surplus.
The preferred weight percent of each composition of Biphenthrin emulsion in water of the present invention:
Biphenthrin 3～30%
Hydrophilic lipophilic balance HLB is 5～18 emulsifier 3～15%
Organic solvent 5～15%
Stablize antifreezing agent 3～10%
Water surplus.
The emulsifier that the present invention adopts is Sulfonates, phosphoric acid ester or polyethers or their any composite emulsifier.
Wherein, described Sulfonates emulsifier is alkyl benzene calcium sulfonate (as newborn No. 500 of farming) or sodium alkyl benzene sulfonate; Described phosphoric acid esters wedding agents is alkylphenol polyoxyethylene phosphate (as OP-10 phosphate, OP-15 phosphate) or aliphatic alcohol polyoxyvinethene phosphate (as MAP); Described polyethers emulsifier is alkylphenol polyoxyethylene (as farming breast No. 100, OP-10), phenethyl phenol polyethenoxy ether (as agricultural emulsifier NO), poloxalkol (as No. 33, farming breast, No. 34, farming breast), castor oil polyoxyethylene ether (as By125, By140), aliphatic acid polyethenoxy ether (as AO-10), fatty alcohol-polyoxyethylene ether (as No. 200, farming breast, peregal, OS-15) or sorbitan monooleate APEO (as Tween-80, Tween-65).Above-described various hydrophilic lipophilic balance HLB is that 5～18 emulsifier abbreviates the EW7502 emulsifier as.
Composition of the present invention comprises that also percentage by weight is 0～2% thickener, and thickener can adopt one or more any combination in polyacrylate, Magnesiumaluminumsilicate, carboxymethyl cellulose, xanthans or the Sodium Polyacrylate.
Organic solvent is one or more any combination in dimethylbenzene, toluene, ethanol, cyclohexanone or the solvent naphtha; Described stable antifreezing agent is one or more any combination in ethylene glycol, propane diols, urea, glycerine or the isopropyl alcohol.
Water of the present invention can be running water or deionized water.
The preparation technology of Biphenthrin emulsion in water of the present invention, its preparation process is as follows:
Get above-mentioned raw materials by weight percent, at first Biphenthrin and organic solvent are mixed under mechanical agitation, form oil phase; Water and stable antifreezing agent, emulsifier are dropped in the emulsification Scattered Kettle, and begin to stir under 200～15000 rev/mins rotating speed, its optimum speed is 1000～8000 rev/mins; Then oil phase is dropped in the emulsification Scattered Kettle, stirred 20～100 minutes, the best stirring 30～60 minutes makes it to become even emulsion.
The preparation technology of Biphenthrin emulsion in water of the present invention, its preparation process can also be as follows:
Get above-mentioned raw materials by weight percent, at first Biphenthrin and organic solvent, emulsifier EW7502 are dropped in the emulsification Scattered Kettle and mix, begin to stir under 200～12000 rev/mins rotating speed, its optimum speed is 1000～8000 rev/mins, forms oil phase; With putting at a slow speed in the emulsification Scattered Kettle after water and the mixing of stable antifreezing agent, to stir 10～100 minutes, the best stirring 20～60 minutes makes it to become even emulsion.
Advantage of the present invention and good effect are:
What 1, pesticide emulsion in water was with practical value is oil-in-water type, and promptly oil is disperse phase, and water is continuous phase, and pesticide active ingredient is at oil phase.Aqueous emulsion is compared with missible oil, advantage is not contain or only contain a small amount of poisonous inflammable aromatic hydrocarbon solvent, thereby can avoid producing with transporting procedures in burning and blast, there is not unpleasant poisonous smell, little to eye irritation, reduced pollution, improved safety greatly production, storing and user to environment; Water with cheapness is matrix, and emulsifier consumption and missible oil are approximate, though increased auxiliary agents such as some co-emulsifiers, antifreeze, because skyrocketing of petroleum product price still can be competed with same concentrations missible oil in business accounting.Aqueous emulsion in use drifts about and alleviates, and does not have wetting powder to spray back vestiges and missible oil to make phenomenons such as the fruit powder comes off, and its drug effect is with suitable with the corresponding missible oil of dosage.
2, use water to replace organic solvent in the aqueous emulsion, the toxicity of warm blooded animal is reduced greatly, than missible oil safety, its active matter content modification scope is big to the toxicity of plant.Aqueous emulsion is compared with microemulsion, because the amount of auxiliary that it consumed is less, so production cost is well below microemulsion.From can preparing the pesticide concentration scope, but the aqueous emulsion compound concentration up to more than 60%, and microemulsion can only be below 20%; And aqueous emulsion under certain condition can be mixed mutually with other medicament such as suspending agent or liquid fertilizer, as can be compound with aqueous suspension (SC), makes suspending agent (SE).
