Abstract
The invention discloses hexaconazole aqueous emulsion agent, which belongs to the disinfectant technology in the crop protection field. The composition of the invention comprises the contents that: hexaconazole occupies 8 to 80 percent, emulsifying agent occupies 2 to 40 percent, stabilizing agent occupies 2 to 10 percent, anti-freezing agent occupies 5 to 8 percent, antifoaming agent occupies 10 to 20 percent, dissolving agent occupies 10 to 20 percent, hydrotropy agent occupies 10 to 20 percent, and the residual is water. The preparation method is realized by that the preparation of the aqueous emulsion agent is performed in an emulsion pot, and the processing procedure is realized that the original medicine is mixed with the dissolving agent and the hydrotropy agent through the mechanical mixing, then the emulsifying agent and the stabilizing agent are added and evenly mixed, finally water is added, and the mixture is mixed for 10 to 30 minutes under the rotation speed of 100 to 12000 circles per minute, to ensure that the mixture forms the even lacteous product. The invention is a new dose type of hexaconazole-aqueous emulsion agent, and overcomes the disadvantages of emulsifiable oil, wettable powder, and suspending agent, the aqueous emulsion agent can reduce the use-cost of farmers and the pollution to the environment, and the invention reduces the environmental pollution, the toxicity of agricultural chemicals, and the product cost, as well as enhances the security and the medicine effect.
Description
Technical field
What the present invention relates to is a kind of agricultural broad-spectrum germicide hexaconazole aqueous emulsion and preparation method thereof. particularly a kind of having prevention and treating hexaconazole aqueous emulsion of double action and preparation method thereof at apple, grape powdery mildew, rice sheath blight disease, false smut, pear scab or the like development.
Background technology
Own azoles alcohol is a kind of wider bactericide, and main feature is: 1, wide spectrum.All effective to multiple diseases.2, efficient.In current hypotoxicity bactericide own azoles alcohol be drug effect than higher, in state-owned several families manufacturer production, its product is formulations such as microemulsion, missible oil, suspending agent, these several formulations are little to the harm of environment, but transportation is inconvenient, stores shortcomings such as inconvenience.This profit dispersiveness of aqueous emulsion as far back as 19th century in early days just the someone begin one's study, but aqueous emulsion because of its stability you be fine, also layering, factors such as the large usage quantity of surfactant, this novel form of also little aqueous emulsion in the conventional pesticide kind so far.The objective of the invention is in order not use or reduce the usage amount of aromatic organic solvent as far as possible; reduce emulsion pollution to environment when using; health with protection environment and user; in addition; owing to replace a large amount of organic solvents with water, improved the safety in production, transportation and the storage process.The present invention proposes aqueous emulsion that uses own azoles alcohol and preparation method thereof for this reason.
Summary of the invention
The invention provides a kind of hexaconazole aqueous emulsion and preparation method thereof.
A kind of aqueous emulsion, own azoles alcohol be as active component, contains that emulsifier 2～40%, stabilizing agent 2～10%, antifreeze 5 parts～8%, defoamer account for 1～5%, solvent 10～20%, cosolvent 10～20% and excess water, more than all be weight percentage.
Emulsifier is one or more in aliphatic alcohol polyoxyvinethene phosphate, alkylphenol polyoxyethylene formaldehyde condensation products, alkylphenol polyoxyethylene, alkyl benzene calcium sulfonate, alkylphenol polyoxyethylene phosphate, the fatty alcohol-polyoxyethylene ether.
Stabilizing agent newspaper is drawn together a kind of in sodium hydrogen phosphate, succinic acid, adipic acid, oxalic acid, the borax
Antifreeze is one or more compositions of ethylene glycol, propane diols, glycerine, urea, ammonium sulfate etc.
Defoamer generally is meant organosilicon.
Solvent is meant that toluene, dimethylbenzene, ethanol, methyl alcohol, propyl alcohol, dimethyl formamide, n-butanol, cyclohexane, isopropyl alcohol, cyclohexanone prop up one or more that the slave does.
Cosolvent is one or more compositions in n-octyl alcohol, n-butanol, ethylene glycol, glycerine, polyethylene glycol, the methyl-sulfoxide.
The preparation method that a kind of own azoles alcohol is aqueous emulsion is
1, composition of raw materials: own azoles alcohol azoles 8～80%, emulsifier 2～40%, stabilizing agent 2～10%, antifreeze 5 parts～8%, defoamer account for 1～5%, solvent 10～20%, cosolvent 10～20% and excess water;
2, preparation method: preparation should be carried out in the emulsification axe, its procedure is: at first former medicine and solvent and cosolvent are mixed under mechanical agitation, drop into emulsifier then and stabilizing agent stirs, add entry at last, under 100～12000 rev/mins rotating speed, stirred 10～30 minutes, and made it to become the product of even emulsus
Advantage of the present invention and good effect are:
1, reduced environmental pollution: aromatic organic solvent content and only contains 5-30% up to 45-60% in the conventional cream preparation in the aqueous emulsion, has reduced the aromatic organic solvent usage amount, thereby has reduced environmental pollution.
2, reduced the toxicity of agricultural chemicals.
3, improved safety:, improved the safety in production/storage and the transportation because water has replaced most of organic solvent.
4, improved drug effect.
