Abstract

The invention discloses an emulsion in water containing lufenuron and a preparation method thereof; compared with the traditional emulsion in water, the emulsion in water is different in that the emulsion in water adopts more environmentally friendly solvent in stead of traditional toluene and xylene and adds proper emulsifier, UV-protectant, thickener, antifreeze, antifungal agent, defoamer and other additives and the balance water to prepare the stable emulsion in water by certain processing methods. Compared with the traditional emulsifiable solution, the emulsion in water reduces the dosage of organic solvent which is harmful to the environment, avoids the effects of the preparation to the environment and the health of users and corresponds to the current green agricultural development direction.

Description

A kind of aqueous emulsion that contains lufenuron and preparation method thereof
Technical field
The present invention relates to a kind of pesticidal preparations and preparation method thereof, especially a kind of aqueous emulsion that contains lufenuron and preparation method thereof.
Background technology
Aqueous emulsion is an important directions of present formulations of pesticide development, is that water-fast original liquid body or former medicine are dissolved in a kind of formulations of pesticide of water-fast organic solvent gained Solution Dispersion in water.Compare with other formulation, the advantage of aqueous emulsion is low toxicity, environmental protection, without catching fire danger, storage and convenient transportation, and can mix with arbitrary proportion with water, shortcoming is relatively difficulty of research and development, and at present suitable auxiliary agent and solvent phase are fewer to selecting.Prepare suitable aqueous emulsion, pesticide original medicine must possess several conditions, and at first the solvability in the water should be relatively low, and General Requirements is lower than 200mg/L, and secondly chemical stability will be got well, and is difficult for having the generation of decomposing phenomenon in water.The main points of aqueous emulsion exploitation are by the means of high shear the oil droplet of aqueous phase to be broken into micron-sized dispersity, by the adding of auxiliary agent it are carried out the chemistry parcel, reduces surface energy or utilize the repulsive interaction of surface electrical layer so that whole aqueous emulsion stable system simultaneously.The aqueous emulsion that meets at present cold (heat) storage stability, dilution stability, pourability, viscosity and pH value index is also fewer, and the report of being correlated with both at home and abroad is also few, therefore also has sizable research and development potentiality in this direction.In today that the conventional dosage forms such as missible oil are paid attention to for people day by day for the harm of human and livestock health and living environment, the application potential of aqueous emulsion has been pointed out the road of a light undoubtedly.
Lufenuron (Lufenuron) is a kind of novel benzoyl area kind insecticidal/acaricidal agent by the exploitation of Switzerland Syngenta Co.,Ltd; its chemistry RS by name)-and 1-[2,5-two chloro-4-(1,1; 2; 3,3,3-hexafluoro propoxyl group) phenyl]-3-(2; the 6-difluoro benzoyl) urea; this is a kind of inhibiting insect growth regulator, IGR of chitin synthesis that has, and has unique insecticidal mechanism, by acting on insect larvae, stoping the decortication process to kill off the insect pests.Lufenuron is mainly used in preventing and treating the insects such as diamond-back moth, lima bean pod borer, thrips, the blue or green worm of swallow, cotton bollworm, to crop safety, corn, vegetables, oranges and tangerines, cotton, potato, grape, Soybean and Other Crops all can be used, it is advantageous that the insect that can prevent and treat pyrethroid and organophosphorous pesticide generation resistance, be suitable for Integrated pest and administer.
The long-term use of single medicament often causes the raising of pest resistance to insecticide, increases the difficulty of control, affects the output of crop.Therefore, by using Recompounded pesticide to increase drug effect, reduce cost, enlarge insecticidal spectrum, increasing economic efficiency, become most countries and regional agriculturist's selection.
A kind of pesticide original medicine is made aqueous emulsion, but its particle diameter can be less than the particle diameter of traditional wet-milling (WP), suspending agent (SC), and drug effect is better, but and compare with wet-milling, aqueous emulsion without dust, endangers little to producer, user in making, using.But the aqueous emulsion solvent for use has certain restriction, and lufenuron etc. then are difficult to be dissolved in the general organic solvent, therefore, makes aqueous emulsion and has certain difficulty.Mostly aqueous emulsion in the past is the volatile poisonous organic solvents such as toluene, dimethylbenzene if adopting, larger for environment and people and animals' harm, and for as Avermectin, first to tie up the former medicine solvability such as salt not high, hindered the application of aqueous emulsion in these fields.
In view of this, be necessary to provide a kind of utilize the higher solvent of relative environmental protection and solvability contain lufenuron aqueous emulsion and preparation method thereof.
Summary of the invention
The object of the invention is to: a kind of high stability aqueous emulsion that contains lufenuron and preparation method thereof is provided.
Research and develop a kind of stable water emulsion formula, its key problem is the selection of solvent, the inventor is on the basis of in the past researching and developing experience, through large quantity research and experiment sieving, find the part water-immiscible solvent, wherein a kind of or its combination as in reformed arene class, alkyl phthalate class, alkylene carbonate class, ionic liquid class, the N-alkyl pyrrolidine ketone is suitable as solvent and is used for the aqueous emulsion that preparation contains lufenuron.
Accordingly, determine the prescription following (mass percent) of lufenuron aqueous emulsion: active components A: 1%-50%; Active component B:0-50%; Solvent 5%-50%; Emulsifier 1%-20%; UV-protectant 0%-3%; Antifreezing agent 0%-8%; Thickener 0%-5%; Mould inhibitor 0%-5%; Defoamer 0%-0.5%; Water: surplus; Above-mentioned active components A is lufenuron, and active component B is Avermectin, or first dimension salt, or capillary, or pleocidin.
Described solvent is wherein a kind of or its combination in reformation aromatic hydrocarbons, alkyl phthalate class, alkylene carbonate class, ionic liquid class, the N-alkyl pyrrolidine ketone.
Described emulsifier is phosphoric acid ester anion surfactant and Pluronic PE 6800, polystyrene-based phenol polyethenoxy base ethers, castor oil polyoxyethylene ether class, polyoxyethylene nonylphenol ether class, fatty alcohol polyethenoxy ether class nonionic surface active agent, can select one of them or its combination.
Because Avermectin and first dimension salt can decompose under illumination condition; so in the preparation that contains these two kinds of active components, must add the UV-protectant; protectant commonly used has butylhydroxy anisole (BHA) or 2,6-Butylated Hydroxytoluene (BHT).
Described antifreezing agent is a kind of or its combination in ethylene glycol, propane diols, glycerine, the urea.
Described thickener is a kind of or its combination in xanthans, hydroxy alkyl cellulose class, polyvinylpyrrolidone, the polyvinyl alcohol.
Described mould inhibitor is a kind of or its combination in Sodium Benzoate, formaldehyde, the sorbic acid.
Described defoamer is a kind of or its combination in silicone based, the alcohols.
The above-mentioned preparation method who contains the aqueous emulsion of lufenuron may further comprise the steps: 1) former medicine A or former medicine A and former medicine B are dissolved in the solvent, optionally add the emulsifier of low HLB (5-7) or do not add and obtain oil phase; 2) emulsifier, UV-protectant, antifreezing agent, defoamer, thickener, mould inhibitor and the water with high HLB (＞10) is mixed to get water; 3) under high shear, oil phase is joined aqueous phase or water is joined in the oil phase, make the aqueous emulsion of high stability; Wherein, the 1st) step and the 2nd) order in step in no particular order.
Compared with prior art, the aqueous emulsion that contains lufenuron of the present invention is selected the solvent of relative environmental protection, and under the cooperation of corresponding emulsifier and other auxiliary agent, has reached certain stability.
