Abstract
The invention relates to a pesticide preparation, in particular to a chlorbenzuron suspending agent and a preparation method thereof. The chlorbenzuron suspending agent is prepared by mixing a technical product of chlorbenzuron, a wetting agent, a dispersing agent, an adhesion agent, an antifreezing agent, an antiseptic agent, a defoaming agent and deionized water. The preparation method comprises the following steps of: putting the ingredients in a barrel by a certain proportion, smashing the ingredients by a high shearing machine for evenly mixing, then grinding the above ingredients by a sand mill until the solid grain diameter is less than 4mum, and finally carrying out packing after the quality reaches standard in quality inspection, thus obtaining the preparation. The chlorbenzuron suspending agent has the advantages of having good insect prevention effect, being safe to humans, animals, natural enemies of pests or other beneficial organisms, preventing the large amount of organic solvent from polluting environment, having simple equipment technique and low cost, and being suitable for popularization and application.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, relate to specifically a kind of Chlorbenzuron deflocculant and preparation method thereof.
Technical background
Use at traditional agricultural chemicals, mainly be missible oil and pulvis, the level of the productive forces is not in the very high situation in the past, for prevention and elimination of disease and pests plays a significantly greater role, but because missible oil all is that former medicine and emulsifiers dissolve form, in the process of using, environment has been caused very large burden in organic solvent.Pulvis because in use is easy to drift, brings adverse influence for user and surrounding environment, develops a kind of novel form, and is especially aobvious important.
Suspending agent is a kind of novel form of pesticide processing.It is that pesticide original medicine and carrier and dispersant and water form, and utilizes wet method to carry out the thickness that ultramicro grinding forms and can flow without dust, low, the drug effect high of cost.And have the advantage of wetting powder and missible oil concurrently, and can be moistening by water, suspension is good behind the thin up.Suspending agent has the following advantages: (1) is without dust harzard, to operator and Environmental security; (2) take water as dispersion medium, the inflammable and drug injury problem that is not produced by organic solvent; (3) compare with wetting powder, allow to select the former medicine of different-grain diameter, in order to make the biological effect of preparation and physical stability reach best; (4) liquid suspension spreads in water well, can directly make spray liquid and use; (5) than great, packaging volume is little.(6) dispersiveness of suspending agent and plate-out ability are all relatively good, and suspensibility is high, and the ability that sticks to the plant corpus surface is more intense, resistance of rainwater washing against, thereby drug effect is than wetting powder significantly and also more lasting.(7) have that particle is little, active surface is large, penetration is strong, when making up a prescription without dust, low, the drug effect high of cost.And have the advantage of wetting powder and missible oil concurrently, and can be moistening by water, suspension is good behind the thin up.
The young urea that goes out is a kind of insect growth regulator, IGR, belongs to specificity insecticide.After insect took food or contacts medicament, it was chitinous synthetic to suppress epidermis, larva can not normally be casted off a skin and dead.Mainly be stomach poison function, certain action of contace poison is also arranged, but without interior absorption.Lepidoptera and Diptera larvae are had special efficacy, do not kill adult, but can make adult sterile, ovum can not normally be hatched.Toxicity is low, to people, animal and plant safety, natural enemy is killed and wounded little, and drug effect is slower, could show insecticidal action after 2～3 days.The young urea that goes out is made the suspending agent liquid, and to stick to the ability on plant corpus surface more intense, resistance of rainwater washing against, thereby drug effect is significantly and also more lasting.
Summary of the invention
The object of the invention is to propose a kind of Chlorbenzuron deflocculant and preparation method thereof.
Purpose of the present invention is achieved through the following technical solutions:
1. Chlorbenzuron deflocculant is characterized in that following step: percentage by weight is supplied by benzoylphenyl urea original medicine 10%-50%, wetting agent 0.5%-5%, dispersant 0.5%-10%, tackifier 0.2%-4%, antifreezing agent 1%-5%, preservative 0.1%-3%, defoamer 0.1%-5%, stabilizing agent 0.01%-5% and deionized water for it.
Described wetting agent be selected from alkylphenol-polyethenoxy polyethenoxy ether, aliphatic alcohol polyethenoxy polyethenoxy ether, calcium lignosulfonate, to any one or multiple combination of methoxyl group fatty acid amide benzene sulfonic acid sodium salt, sorbitol polyoxyethylene base ether, alkylphenol-polyethenoxy base ether formaldehyde condensation products etc.
3. described dispersant is selected from one or more combinations of phenethyl phenol polyethenoxy sodium sulphate, calcium lignosulfonate, sodium lignin sulfonate, alkylphenol polyoxyethylene formaldehyde condensation products, phenethyl phenol polyethenoxy ether formaldehyde condensation products etc.
4. described tackifier are selected from one or more combinations of methylcellulose, methylol methylcellulose, HEMC, xanthans, sodium alginate, gum Arabic, bentonite, white carbon, starch, acrylic acid etc.
5. described antifreezing agent is selected from ethylene glycol, propane diols, glycerine, polyethylene glycol, sorbierite, glycerine, urea, CaCl
2, NaCl etc. one or more combinations.
6. described preservative is selected from one or more combinations of potassium sorbate, Sodium Benzoate, sodium salicylate, Ni Baijin ester class etc.
7. described defoamer is selected from silicone defoaming agent, C
10-20Saturated fat acids, C
8-10In aliphatic alcohols, the tributyl phosphate etc. any.
8. described stabilizing agent is selected from any of pyrogallol, sodium sorbate, cresyl glycidyl ether, epoxidized soybean oil, linseed oil, nipasol etc.
The invention provides a kind of efficient, low toxicity, pollution-free, Chlorbenzuron deflocculant that environment, people, animal safety and insect are difficult for developing immunity to drugs and preparation method thereof, said preparation is with water to replace organic solvent, it is by dispersant, the physical dispersion effect of wetting agent and sand mill, the young urea that will go out is dispersed in the water with the particle diameter below the 4 μ m, forms preparation.
The present invention has the following advantages:
The young urea that goes out is dispersed in water with the particle of miniaturization, has: (1) flash-point is high, does not burn and does not explode, and produces and storing and transporting security; (2) take water as medium, environmental pollution is little, to the producer and user and Environmental security; (3) dust is few, and environmental pollution is little; (4) said preparation with less distribution of particles at target site, good disinsection effect.
