Abstract
The invention discloses a preparation method of a diflubenzuron suspension; the preparation method comprises the steps: diflubenzuron is taken as an active agent, added with a dispersing agent, a wetting agent, a thickener, an antifreeze, a defoaming agent and water and the obtained mixture is processed into the diflubenzuron suspension. The diflubenzuron suspension takes water as a medium, has low production cost, contains no organic solvent and is safe and environment-friendly. The preparation method is simple and feasible, and the products have good effects.
Description
Technical field
The present invention relates to a kind of pesticides new formulation, specifically relate to a kind of insecticide, particularly diflubenzuron suspension, the invention still further relates to a kind of preparation method of diflubenzuron suspension.
Background technology
Diflubenzuron belongs to urea insecticide, is that early seventies is by the commercial the earliest process for preparation of benzoylurea compounds kind of Dutch Duphar company.Diflubenzuron mainly is to cast off a skin by interference insect to make insect slowly dead, so be called as " slow-acting type " inhibitor.Because it is it is higher to people, animal, environmental safety, less again to the natural enemy influence, have outstanding selectivity and be otherwise known as " third generation insecticide ", " ecotopia chemicals ".Diflubenzuron has been got permission registration in about 40 countries and is used since coming out.
Agricultural chemicals suspension agent is not water-soluble solid pesticide or the dispersion of immiscible liquids agricultural chemicals in water or oil.Suspending agent is that domestic and international pesticide industry is generally acknowledged, once is referred to as the novel form of " epoch-making ".Undoubtedly, the exploitation of this novel form, the production and the application of giving the solid pesticide that is insoluble in water and organic solvent have been started vast potential for future development, and have been had very strong competitiveness.Because he has outstanding advantage than wetting powder, milk powder and missible oil, and be studied, production and application units extensively note and pay attention to.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of diflubenzuron suspension.
Another object of the present invention is to work out that a kind of drug effect is good, and cost is low, the diflubenzuron suspension that Environmental compatibility is good.
The objective of the invention is to be achieved through the following technical solutions:
A kind of diflubenzuron suspension, the percentage by weight of each component is in the prescription: diflubenzuron 5-70%, dispersant 2-12%, wetting agent 2-10%, antifreezing agent 1-5.0%, preservative 0.1-2.0%, defoamer 0.1-2.0%, thickener 0.2-1.0%, water is mended to 100%.
Described wetting agent is selected from alkylphenol-polyethenoxy base ether formaldehyde condensation products, alkyl benzene calcium sulfonate, alkylsulfonate or sulphate, phenethyl phenol polyethenoxy ether sodium sulfate salt or phosphate, one or more in the sorbitol polyoxyethylene base ether.
Described dispersant is selected from lauryl alcohol polyethylene glycol oxide base ether sodium sulfate, the alkyl naphthalene formaldehyde condensate sulfonates, neopelex, lauryl sodium sulfate, potassium oleate, enuatrol, alkyl polyoxyethylene ether sulfonate, alkylphenol-polyethenoxy base ether formaldehyde condensation products, alkylphenol-polyethenoxy base ether Nonyl pheno base ether, polyoxyethylene polyoxypropylene base ether inlay and break copolymer draws back powder, one or more in the poly-second carboxylic esters sodium salt.
Described antifreezing agent is selected from ethylene glycol, glycerine, one or more in the propane diols.
Described preservative is selected from sodium salicylate, parabens, Sodium Benzoate, one or more in the potassium sorbate.
Described defoamer is selected from silicone based, sulfonamides, one or more in the higher aliphatic.
Described wet concentration is from running water.
The present invention mainly contains following advantage:
1, no dust harzard is to operator and Environmental security;
2, with water be dispersion medium, not inflammable the and drug injury problem that produces by organic solvent;
3, compare with wetting powder, allow to select for use the former medicine of different-grain diameter, so that 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, the dispersiveness of suspending agent and plate-out ability can be relatively good, the suspensibility height, and the ability that is attached on the plant corpus surface is more intense, resistance of rainwater washing against, thereby drug effect significantly and also compares lastingly than wetting powder.
7, have that particle is little, active surface is big, penetration is strong, do not have dust when making up a prescription, characteristics such as cost is low, drug effect height.And have the advantage of wetting powder and missible oil concurrently, and can be by water-wet, suspension is good behind the thin up.
