Description

A kind of microemulsion insecticide and production method thereof
Technical field
The present invention relates to a kind of insecticide, specifically a kind of microemulsion insecticide and production method thereof belong to the microemulsion insecticide field.
Background technology
A large amount of uses along with agricultural chemicals have brought serious pollution to natural environment, have caused the common concern of the parties concerned.Particularly in today that environmental protection is day by day improved and is strict with, the cry that reduces pesticide pollution more and more adds strongly.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 is comprised of liquid pesticide, surfactant, water, stabilizing agent etc., belong to thermodynamics through the time stable dispersion, mainly take water as medium, do not contain or contain less organic solvent, thereby do not fire not quick-fried, production operation, storing is safe, low in the pollution of the environment, saves a large amount of organic solvents; The pesticide dispersion degree is high, reaches the miniaturization degree, and the agricultural chemicals particle is generally 0.1~0.01 micron, and outward appearance is similar to transparent or sub-translucent liquid; Good dispersion in water is strong to the target body permeability, adhesive force good.
Yet, the problems such as layering, crystallization, muddiness, floccule often appear in present microemulsion product in market, particularly in-20 ℃ the north, such as areas such as Heilungkiang, the Inner Mongol, also the phenomenon of freezing can occur, thereby greatly affect 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 method thereof are provided, after adding methyl alcohol, cyclohexanone, triphenyl vinyl phenol polyoxyethylene poly-oxygen propylene aether, agricultural newborn 404#, polyoxyethylene nonylphenol ether, 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 3.5-35%, 3-20% methyl alcohol, 2-10% cyclohexanone, the newborn 404# of 2-6% farming, 2-6% triphenyl vinyl phenol polyoxyethylene poly-oxygen propylene aether, 2-6% polyoxyethylene nonylphenol ether, water complementary;
Wherein, described former medicine is one or both in beta-cypermethrin, gamma cyhalothrin, cyfloxylate, Methomyl, carbosulfan, desinsection list, dimehypo, diafenthiuron, HEXAFLUMURON, first dimension salt, Avermectin, the matrine.
Preferably, the one-tenth by following percetage by weight is grouped into:
20% former medicine, 10% methyl alcohol, 5% cyclohexanone, 4% agricultural newborn 404#, 4% triphenyl vinyl phenol polyoxyethylene poly-oxygen propylene aether, 4% polyoxyethylene nonylphenol ether, water complementary.
Preferably, 20% former medicine is grouped into by the one-tenth of following percetage by weight: 0.3% Avermectin, 19.7% desinsection list.
Avermectin is the natural materials from Soil Microorganism grey streptomycin.Wherein the strongest with the Bla composition activity, be that good antibiotic desinsection is hidden agent extremely from.Be characterized in the broad-spectrum high efficacy low-residual and to people and animals and Environmental security, stomach toxicity and the action of contace poison of insect hidden from agent without cross resistance extremely with chemistry commonly used again, thereby become one of present China suitability for industrialized production large-tonnage biopesticide.The desinsection list belongs to nereistoxin pesticide.It is extremely strong interior suction, stomach toxicity, tagging has the good bionical insecticide of stifling ovicidal action, noresidue concurrently.Avermectin mainly shields, and without systemic activity, and the longevity of residure is short, and the desinsection list has systemic action, and the longevity of residure is long.There is greatest differences in both chemical constitutions, and each self-applying rake mark is also different.The Avermectin Main Function suppresses neurotransmission in insect neurotransmitter GABA, and the desinsection list is the second phthalein choline competitive inhibitor of insect, makes the insect paralysis.The two is used with, and good preventive effect can be arranged, and can delay again the generation of insect pest resistance.
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;
The triphenyl vinyl phenol polyoxyethylene poly-oxygen propylene aether, cas 99734-09-5, molecular formula C 30H 24O .(C 2H 4O) N, model 1601 in the present invention as emulsifier and stabilizing agent, reduces resolution ratio;
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 method 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, 15-25 minute;
(3) triphenyl vinyl phenol polyoxyethylene poly-oxygen propylene aether, agricultural newborn 404# and polyoxyethylene nonylphenol ether are joined in the agitator tank of above-mentioned steps (2), stirred 20-30 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 the materials such as beta-cypermethrin, gamma cyhalothrin, cyfloxylate, Methomyl, carbosulfan, desinsection list, dimehypo, diafenthiuron, HEXAFLUMURON, first dimension salt, Avermectin, matrine;
2, formulation is stable: after adding triphenyl vinyl phenol polyoxyethylene poly-oxygen propylene aether, agricultural newborn 404# and polyoxyethylene nonylphenol ether, less than 1%, cold storage-25 ℃ 90 days is not freezed non-crystallizable, and is higher than missible oil stability in 60 ℃ of 90 days resolution ratios of heat storage;
3 prescriptions are simple, convenient for production: only need an agitator tank, working condition requires low.
