Description
Technical field
The present invention relates to a kind of insecticide, specifically a kind of microemulsion insecticide and production technology thereof belong to the microemulsion insecticide field.
Background technology
Along with being widely used of chemical pesticide, how to reduce the pollution of environment and to people and animals' murder by poisoning, more and more paid close attention to by people, therefore, reducing toxicity, improving drug effect is the inexorable trend of Agrochemicals.Research and develop to realize that by formulation the purpose that reduces toxicity, improves drug effect is efficiently mode of a kind of comparatively economy for former medicine research and development.The pollution that causes in the applying pesticides process has a large amount of subsidy compositions such as poisonous organic solvents etc. in murder by poisoning that the drift of farm chemical ingredients itself disperses, causes with water and soil loss and the residual and preparation on crop, fruit.In recent years, in countries such as the U.S., in the pesticidal preparations to an organic solvent restriction increasingly stringent, thereby impel the formulations of pesticide to constantly update and to develop, wherein Water-borne modification is exactly one of dominant direction of formulations of pesticide development.Therefore, with water section or replace all that the microemulsion of organic solvent just arises at the historic moment in the missible oil.Microemulsion (Microemulsion) is one of novel form that meets the Agrochemicals direction, and international code name: the ME of formulation is comprised of water, water-insoluble and water-soluble substance, and former medicine is with the microparticulate preparation wherein of 0.01-0.1 micron.It is stable homogeneous phase on the thermodynamics, the solubility system.Outward appearance is transparence, and microcosmic is to be the limiting condition that aqueous emulsion fully disperses for the large micellar dispersion that expands.Its physics, chemical stability are good, and strong to plant and insect tissue cell permeability, absorption ratio is high, and preventive effect is good, simultaneously, have production, storing and use safety, and environmental pollution is little, is conducive to the improvement of ecotope.
Yet the problems such as layering, crystallization, muddiness, floccule often appear in present microemulsion product in market, greatly affected the development of this formulation in technical field of pesticide.In addition, the organic solvent that adds in the microemulsion--stupid kind solvent such as toluene, dimethylbenzene and stupid etc., environmental pollution is serious.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, a kind of microemulsion insecticide and production technology thereof are provided, after adding methyl alcohol, cyclohexanone, agricultural newborn 404#, polyoxyethylene nonylphenol ether and agricultural newborn BY-140, the product forms that obtains is stable, synergy is remarkable, and the preparation method is simple.
For addressing the above problem, the present invention by the following technical solutions:
A kind of microemulsion insecticide is grouped into by the one-tenth of following percetage by weight:
The former medicine of 3.8-25%, 3.5-20% methyl alcohol, 5-25% cyclohexanone, the newborn 404# of 2-10% farming, 2-10% polyoxyethylene nonylphenol ether, the newborn BY-140 of 2-10% farming, water complementary;
Wherein, described former medicine is a kind of in chlopyrifos, Hostathion, capillary, ethiprole, cycloxaprid, Methomyl, carbosulfan, diafenthiuron, HEXAFLUMURON, first dimension salt, Avermectin, the Acetamiprid.
Preferably, the one-tenth by following percetage by weight is grouped into:
10% former medicine, 10% methyl alcohol, 15% cyclohexanone, 6% agricultural newborn 404#, 6% polyoxyethylene nonylphenol ether, 6% agricultural newborn BY-140, water complementary.
Preferably, described former medicine is Acetamiprid.
Acetamiprid belongs to the Nitromethylene heterocycle compound, it is a kind of novel pesticide, act on the nAChR at insect nerve system cynapse position, the neural stimulation conduction of interference insect, cause the nervous system path blockade, cause neurotransmitter acetylcholine in the accumulation at cynapse position, thereby cause the insect paralysis, final dead.
Methyl alcohol claims again " another name for " or " another name for ", is the colourless volatile liquid of alcohol smell that has, for the manufacture of formaldehyde and agricultural chemicals etc., and as the denaturant of organic extractant and alcohol etc.;
Cyclohexanone, for carbonylic carbon atom is included in saturated cyclic ketones in the hexatomic ring, colourless transparent liquid is industrial main as organic synthesis raw material and solvent;
Polyoxyethylene nonylphenol ether has another name called OP-10, and this product has good infiltration, emulsification, dispersion, antiacid, alkali resistant, anti-hard water, anti-reduction, oxidation resistance, in the present invention as emulsifier and stabilizing agent;
The production technology of above-mentioned microemulsion insecticide may further comprise the steps:
(1) takes by weighing each raw material according to above-mentioned prescription;
(2) first former medicine is joined in the agitator tank, again methyl alcohol, cyclohexanone are joined in the agitator tank, stir, 20-25 minute;
(3) the newborn BY-140 of farming, agricultural newborn 404# and polyoxyethylene nonylphenol ether are joined in the agitator tank of above-mentioned steps (2), stirred 25-30 minute, to fully dissolving;
(4) at last water is joined in the agitator tank of above-mentioned steps (3), stirred 25-30 minute, obtain formulation products.
The invention has the advantages that:
1, applied widely: former medicine can adopt a kind of in chlopyrifos, Hostathion, capillary, ethiprole, cycloxaprid, Methomyl, carbosulfan, diafenthiuron, HEXAFLUMURON, first dimension salt, Avermectin, the Acetamiprid;
2, formulation is stable: after adding methyl alcohol, cyclohexanone, agricultural newborn 404#, polyoxyethylene nonylphenol ether and agricultural newborn BY-140, less than 1%, cold storage-25 ℃ 60 days is not freezed non-crystallizable, and is higher than missible oil stability in 60 ℃ of 60 days resolution ratios of heat storage;
3 prescriptions are simple, convenient for production: only need an agitator tank, working condition requires low.
