Abstract
The invention discloses a flonicamid water emulsion and a method for preparing the flonicamid water emulsion. The flonicamid water emulsion comprises the following components in percent by weight: 1-15% of flonicamid, 3-25% of solvent, 4-15% of emulsifying agent, 0.5-2% of dispersing agent, 1-5% of stabilizing agent, 1-5% of anti-freezing agent and the balance of deionized water. The method for preparing the flonicamid water emulsion comprises the following steps: dissolving the flonicamid into the solvent, adding the emulsifying agent, the stabilizing agent and the dispersing agent to prepare an oil phase, mixing the anti-freezing agent with the deionized water to prepare a water phase, and adding the oil phase into the water phase or the water phase into the oil phase slowly under the high shearing condition to prepare the flonicamid water emulsion. The flonicamid water emulsion is a safe and environmentally friendly agricultural pesticide with a good effect.
Description
Technical field
The present invention relates to a kind of pesticidal preparations and preparation method thereof, a kind of specifically flonicamid aqueous emulsion and preparation method thereof.
Background technology
Flonicamid is effective to various suckings pest, and has the good penetration effect.It can be from root to the infiltration of stem, leaf portion, but by leaf portion to stem, root osmosis relatively a little less than.This medicament causes effect through hindering the insect act of sucking, and insect stops to suck after taking in medicament very soon, and is last hungry and dead.Because the mechanism of action that flonicamid is unique and high biologically active, with and to people, animal, the high safety of environment, effective to the insect of other insecticide tool resistances simultaneously, therefore have very big development space.
The modern formulations of pesticide are towards water baseization, ultramicronising, no efflorescence and the development of sustained release aspect; Promptly be the formulations of pesticide of matrix with water; Wherein aqueous emulsion be a kind of organic solvent can be less with in addition the novel pesticide formulation of no, good drug efficacy, environmentally-friendly water-basedization, also be a kind of good liquid dosage form that replaces emulsifiable concentrates for agricultural chemicals.Flonicamid aqueous emulsion of the present invention has efficiently, low toxicity, environmentally friendly, person poultry safety, is prone to the characteristics of degraded.Compare with traditional missible oil; Reduce production costs greatly, save a large amount of petrochemical industry resources, and the present invention adopts the solvent of low toxicity; Significantly reduce organic solvent to the pollution of human body and environment and residual; Produce pollution, explosive and poisoning problem in avoiding producing, pesticide processing is hanged down poison, ensure human and mammiferous safety and health.The environmental pollution that the traditional missible oil phase formulations of pesticide exist, harm is healthy and shortcomings such as manufacturing cost height.
Summary of the invention
The present invention is directed to the prior art deficiency, a kind of efficient, low toxicity, environmentally friendly, person poultry safety are provided and are prone to the flonicamid aqueous emulsion its preparation method producing and use.
Technical scheme of the present invention: for realizing above-mentioned purpose, the present invention provides a kind of flonicamid aqueous emulsion, and each component is following by weight percentage: flonicamid: 1～15%; Solvent: 3～25%; Emulsifier: 4～15%; Dispersant: 0.5～2%; Stabilizing agent: 1～5%; Antifreezing agent: 1～5%; Surplus is a deionized water.
Wherein: described solvent is one or more the mixing among xylol, methyl alcohol, ethanol, n-butanol, ethyl acetate, N-octylpyrrolidone, repefral, diethyl phthalate, dibutyl phthalate, Solvesso100, Solvesso150, the Solvesso200.
Described emulsifier is an APES; The styryl phenol polyethenoxy ether; Alkylaryl polyoxyethylene polyoxypropylene ether; Alkaryl phenol polyethenoxy ether phosphate; Castor oil polyoxyethylene ether; Alkylbenzenesulfonate; Alkylphenol-polyethenoxy phosphate; Polyoxyethylene sorbitan fatty acid ketone; Sorbitan ester; AEO; Maleic acid di-sec-octyl sodium sulfonate; Polyol fatty acid ester and ethylene oxide adduct thereof; Castor oil; The mixing of one or more in the lauryl sodium sulfate.
Described dispersant is one or both the mixing in polycarboxylic acid salt, the alkyl phenol formaldehyde resin polyoxyethylene ether sulphate.
Described stabilizing agent is one or more the mixing in peanut oil, antioxidant 264, epoxidized soybean oil, epoxy linseed oil, epoxy fat, pentaerythrite, xylitol, the pyrogallic acid.
Described antifreezing agent is one or more the mixing in ethylene glycol, propane diols, glycerine, the diethylene glycol.
Flonicamid method for producing aqueous emulsion provided by the invention is: flonicamid is dissolved in the solvent, adds emulsifier, stabilizing agent and dispersant again, make oil phase; Antifreezing agent mixed obtaining water with deionized water, under shear conditions, oil phase is slowly joined aqueous phase or water is slowly joined in the oil phase, make the flonicamid aqueous emulsion.
Flonicamid aqueous emulsion of the present invention is as a kind of water base chemical preparation, and compared with prior art, its preparation form is efficient, low toxicity, environmentally friendly, person poultry safety, is difficult for developing immunity to drugs, and is highly suitable for the various suckings pest of control control.In addition, the stable performance of a kind of flonicamid aqueous emulsion preparation is prone to degraded, and the technological process of production is simple, and investment and cost of equipment are low.
