Abstract
The invention relates to a pesticide preparation, in particular to a hexaconazole suspending agent and a method for preparing the same. The hexaconazole suspending agent comprises the following components by weight percentage: 5 to 60 percent of hexaconazole, 0.2 to 1.0 percent of defoamer, 3 to 15 percent of dispersant, 2 to 8 percent of antifreeze, 0.2 to 3 percent of thickener, 0.05 to 6 percent of stabilizer, 0 to 10 percent of penetrant, and the balance of water. The invention also discloses the method for preparing the hexaconazole suspending agent. The hexaconazole suspending agent of the invention has the advantages of high flash point, non-combustibility, nonexplosivity, safe production, storage and use, little dust, little environmental pollution, low product cost, easy package, good pest-killing effect, and the like.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, specifically relate to a kind of hexaconazole suspending agent and preparation method thereof.The present invention is that own azoles alcohol is the bactericide of active ingredient, add dispersant, bleeding agent, stabilizing agent, antifreezing agent, defoamer, thickener and water, make the high degree of dispersion steady suspension through pulverizing, homogenizing dispersing technology, belong to pesticides new formulation and preparing technical field thereof.
Technical background
The pure product of own azoles alcohol (hexaconazole) are clear crystal, 111 ℃ of fusing points, vapour pressure 0.01mPa (20 ℃), 25 ℃ of density 1.29g/cm
3Stability: room temperature (below 40 ℃), do not decompose at least 9 months, stable in the 30d in Acidity of Aikalinity (pH5.7-9) aqueous solution, stable in the 10d under the irradiation of pH7 aqueous solution middle-ultraviolet lamp.
Own azoles alcohol belongs to azoles fungicide, is sterol demethylation inhibitor, and fungi (especially Basidiomycetes and the Ascomycetes) disease that causes is had the protection and the eradicant action of broad spectrum activity.With the 10-20mg/l spraying, can prevent and treat grape Guignardia and grape snag shell bacterium on apple mildew and apple black star bacteria, the grape effectively; With the 20-50mg/l spraying, can prevent and treat the coffee camel spore rest fungus on the coffee; Can prevent and treat tail spore mould on the peanut with 20-50g/ha.
In recent years, national requirements exploitation friendly environment novel form, formulations of pesticide exploitation is to water baseization, ultramicronising, no dust and the development of sustained release aspect.Wherein water baseization is exactly one of main direction of agricultural chemicals development.Water can reduce the consumption of organic solvent as the suspending agent of solvent, the dust pollution that whether has wetting powder and pulvis to bring, and reduced the pesticide producing cost, become a kind of very important formulation in the pesticide manufacturing.
Summary of the invention
The purpose of this invention is to provide a kind of hexaconazole suspending agent and preparation method thereof.
Another object of the present invention is the physics peptizaiton by the effect of dispersant and sand mill; own azoles alcohol is dispersed in the deionized water with small solid state; thereby provide a kind of consumption that can reduce the organic solvent in the pesticidal preparations, suspending agent that can also the own azoles alcohol of better protection.
The objective of the invention is and can reach by measure once:
A kind of hexaconazole suspending agent, form by following components in weight percentage:
Own azoles alcohol 5%-60%
Defoamer 0.2-1.0%
Dispersant 3-15%
Antifreezing agent 2-8%
Thickener 0.2-3%
Stabilizing agent 0.05-6%
Bleeding agent 0-10%
Water supplies 100%
Dispersant is selected from sodium lignin sulfonate, calcium lignosulfonate, neopelex, calcium dodecyl benzene sulfonate, draws back powder, in the poly-second carboxylic esters sodium salt, dodecyl polyoxyethylene rice phosphate, alkylphenol-polyethenoxy base ether, Nonyl pheno base ether, potassium oleate, enuatrol, lauryl alcohol polyethylene glycol oxide base ether sodium sulfate, alkyl naphthalene formaldehyde condensate sulfonates one or more.
Thickener is selected from one or more in xanthans, CMC, hydroxyethylcellulose, methylcellulose or the polyvinyl alcohol.
Stabilizing agent is selected from one or more in epoxidized soybean oil, linseed oil, citric acid, the sodium sorbate.
Defoamer is selected from one or more in silicone defoaming agent, C8-C10 aliphatic alcohols compound or the II-ethyl alcohol.
Antifreezing agent is selected from one or more in ethylene glycol, glycerine, propane diols, polyethylene glycol, sorbierite or the urea.
Bleeding agent is the organosilicon bleeding agent.
A kind of method for preparing hexaconazole suspending agent, own azoles alcohol is mixed in the described ratio of claim 1 with dispersant, thickener, stabilizing agent, defoamer, antifreezing agent, bleeding agent and water, in sand mill, ground 2-3 hour, particle diameter is all once got final product at 5um.
In the formulations of pesticide, conventional dosage forms is based on missible oil, wetting powder, and water baseization formulation came into the market successively in nearly 2 years, and suspending agent then is representative wherein.Because it is a matrix with water, particle diameter is generally 1-3um, average 90% particle diameter≤5um, and suspensibility 〉=90%, high the opening up and adhesivity of performance on the crop blade face, it uses drug effect to compare with WP, and very big difference is arranged.
The present invention is scattered in the particle of own azoles alcohol miniaturization in the water, thereby has: 1. flash-point height, and do not burn and do not explode, produce and store and safe in utilization; 2. dust is few, and environmental pollution is little, to the producer and user and Environmental security; 3. with water matrix, aboundresources, product cost is low, easily packing; 4. after the said preparation spraying, be distributed in crop surface with fine particle, good drug efficacy; 5. preventive effect is good behind the adding bleeding agent.
