Description
Technical field:
The present invention relates to a kind of agricultural chemicals, be specifically related to a kind of rotenone micro-emulsion.
Background technology:
Rotenone is the efficient insecticide active substance of generally acknowledging in the world, and it is to environment, people and animals, pest natural enemy and other beneficial organism safety, and insect is not easy to develop immunity to drugs, and therefore belongs to environment amenable insecticide active substance.Development along with agricultural science, especially country strengthened the attention to agricultural development in nearly 2 years, make that its importance at control agricultural disease, worm, grass is particularly outstanding, develop multiple rotenone insecticide variety in succession, but formulation mostly is cream preparation, and the use of this cream preparation agricultural chemicals has also brought negative effect to environment, the aromatic hydrocarbons organic solvent that missible oil consumption is a large amount of when improving crop yield, these toxic solvents cause environmental pollution, are detrimental to health.
The modern formulations of pesticide promptly are the formulations of pesticide of matrix with water, promptly with big old formulations of missible oil of water baseization pesticidal preparations replace organic solvent consumption such as suspending agent, microemulsion, aqueous emulsions towards water baseization, ultramicronising, no efflorescence and the development of sustained release aspect.Wherein microemulsion 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.Publication number is that CN101379996 discloses a kind of rotenone micro-emulsion, and this microemulsion comprises that rotenone 1.5-2.5%, solvent 6-17%, emulsifier 9-18%, stable transparent agent 0.01-0.3%, antifreezing agent 0.1-0.6%, surplus are water.But in the above-mentioned rotenone micro-emulsion, rotenone content is low, poor stability and control efficiency are relatively poor.
Summary of the invention:
A kind of rotenone content height, good stability, rotenone micro-emulsion that control efficiency is good have been the purpose of this invention is to provide.
The present invention utilizes the mixing theory of modules and micelle increase-volume theory to be the basis, and the HLB value method and the micellar theory of reference surface activating agent are selected, with environmental friendliness insecticide active substance rotenone and composite blended emulsifier, thereby the microemulsion that is mixed with water baseization has been realized purpose of the present invention.
The present invention is achieved by the following technical programs:
Rotenone micro-emulsion of the present invention comprises by mass fraction:
Rotenone 3～6%

All the other waters complement to 100%.
Described composite anion-nonionic emulsifier is by mass fraction, and tween is 40-80%, and anion surfactant is 1-10%, and surplus is the hydrophily polar solvent.
Described tween is made up of two or more non-ionic surface active agents, and by mass percentage, wherein the content of any one non-ionic surface active agent is not higher than 80%.
Described composite anion-nonionic emulsifier is nonionic and anion surfactant and hydrophilic polar solvent composite obtaining under stirring fast, and this emulsifier has good emulsifying effectiveness.Described tween is the two or more combinations in benzylphenol APEO, alkaryl phenol polyethenoxy ether phosphate, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, castor oil polyoxyethylene ether, styryl phenyl APEO, the polyol fatty acid ester, and wherein the content of any one non-ionic surface active agent is not higher than 80% in tween.Described anion surfactant is one or more the combination in alkylbenzenesulfonate, ether alcohol sulfate, triphen ethyl-phenol polyoxyethylene phosphate and the sulphate.Described polar solvent is one or more the combination in methyl alcohol, ethanol, n-butanol, the ethyl acetate.
Described solvent is one or more the combination in ether, acetone, cyclohexanone, ethyl acetate, dimethyl formamide, the N-Methyl pyrrolidone.
Described assistant for emulsifying agent is one or more the combination in propyl alcohol, hexanol, octanol, isobutanol, ethylene glycol, glycerine, cyclohexanol, methyl diethylene glycol (DEG), ethyl diethylene glycol (DEG), castor oil, the lauryl sodium sulfate.
Described water can be with deionized water or running water or drinking water or natural water.
Of the present invention preferably by mass percentage: rotenone content is 3%, and solvent is a cyclohexanone, and content is 26.7%, and composite anion-nonionic emulsifier is 16%, and assistant for emulsifying agent is a castor oil, and content is 1.3%, and the surplus water supplies 100%; Described composite anion-nonionic emulsifier is: tween is 54.1%, and anion surfactant is a calcium dodecyl benzene sulfonate, and content is 4.1%, and surplus supplies 100% with polar solvent methyl alcohol; Described tween is: fatty alcohol-polyoxyethylene ether 38.5%, OPEO 61.5%.
Rotenone micro-emulsion of the present invention is preparation like this, at first rotenone all is dissolved in the solvent, then emulsifier is slowly added in the entry, and the limit edged stirs, and forms emulsifier aqueous solution, adds assistant for emulsifying agent again, stirs; At last the rotenone of dissolving is directly joined in the emulsifier aqueous solution to mix and stir to become in 0.5-1.0 hour transparence solution and get final product.
Beneficial effect of the present invention is as follows:
1. the present invention substitutes most organic solvent with water; reduce environmental pollution; help ecological environmental protection; also can greatly reduce production costs, save a large amount of petrochemical industry resources, and the present invention adopts and not contain the phenyl ring class and to the solvent of environment or human body 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.
2. the present invention adopts rotenone and composite anion-nonionic emulsifier and the rotenone micro-emulsion that disposes, this microemulsion stable transparent dispersion on thermodynamics is, spray droplet is little in use, have better wetting to crop and polypide, sprawl, adhere to and permeability, the absorption soup is many, improve drug effect, this microemulsion is active high to crop pests, compare with the rotenone micro-emulsion of prior art, the content height, stability is strong, safety is good, rotenone is being diluted under the identical situation of application concentration, the control efficiency of rotenone micro-emulsion of the present invention is apparently higher than rotenone micro-emulsion of the prior art.Rotenone micro-emulsion provided by the invention has efficiently, low toxicity, pollution-free, environmentally friendly, person poultry safety, the characteristics that insect is difficult for developing immunity to drugs.
