example 1

[0028] 30% acetamiprid water dispersible granules. Weigh 30% of the original drug of acetamiprid, 3% of wetting agent alkyl sulfonate, 6% of dispersant alkylphenol polyoxyethylene ether formaldehyde condensate sodium sulfate, 25% of disintegrating agent ammonium sulfate, binder polyoxyethylene Ethylene glycol 2%, kaolin make up 100%, mix them according to the general method, after stirring evenly, pulverize through a jet mill to obtain mother powder, then granulate, dry, and sieve to obtain about 30% acetamiprid water dispersible granules agent. After inspection, the active ingredient content is 30.1%, moisture content is 2.0%, sieving (passing through a 75um sieve) is 99%, suspension rate is 91%, long-lasting foaming property (1min) is 10mL, wettability is less than 1min, and the accelerated heat storage stability is qualified.

example 2

[0030] 40% acetamiprid water dispersible granules. Weigh 40% of the original drug of acetamiprid, 3% of wetting agent alkylsulfonate, 6% of dispersing agent polycarboxylate, 25% of disintegrating agent ammonium sulfate, 2% of binder polyethylene glycol, kaolin supplement 100%, it is mixed according to the general method, after stirring evenly, it is pulverized by a jet mill to obtain mother powder, then granulated, dried, and sieved to obtain about 30% acetamiprid water-dispersible granules. After inspection, the active ingredient content is 40.5%, moisture content is 1.9%, sieving (passing through a 75um sieve) is 97%, suspension rate is 89%, long-lasting foaming property (1min) is 10mL, wettability is ≤1min, and the accelerated heat storage stability is qualified.

example 3

[0032] 50% acetamiprid water dispersible granules. Weigh 50% of the original drug of acetamiprid, 3% of wetting agent alkylnaphthalene formaldehyde condensate sulfonate, 6% of dispersing agent polycarboxylate, 20% of disintegrating agent ammonium sulfate, binder polyethylene glycol 2 %, kaolin to make up 100%, mix it according to the general method, and after stirring evenly, pulverize through a jet mill to obtain mother powder, then granulate, dry, and sieve to obtain about 50% acetamiprid water-dispersible granules. After inspection, the active ingredient content is 50.3%, the moisture content is 2.1%, the sieving (passing through a 75um sieve) is 97%, the suspension rate is 85%, the persistent foaming property (1min) is 10mL, the wettability is ≤1min, and the accelerated heat storage stability is qualified.

Abstract

The invention discloses a pesticide preparation, and in particular relates to a method for preparing acetamiprid water dispersible granules. The acetamiprid water dispersible granules are in regular or irregular granular forms, wherein the content (weight percentage) of the acetamiprid is 30 to 80 percent. The method comprises the following steps that: an acetamiprid active compound is added and mixed with a wetter, a dispersant, a disintegrating agent, a thinner and a binder in a certain proportion; the mixture is uniformly stirred and ground to produce concentrated powder; the concentrated powder is added and uniformly mixed with deionized water in a certain proportion; the uniform mixture is made into grains; and the grains are dried and passed through a sieve and the acetamiprid waterdispersible granules are obtained. The acetamiprid water dispersible granules overcome the drawbacks of suspending agents and wettable powder and reduce the using cost for peasants and environmental pollution in processing and using processes. The acetamiprid water dispersible granules have the advantages of high active ingredient content, quick disintegration, good dispersivity, stable heat-storing performance, and the like due to the addition of additives with different ingredients, and have high pest-killing efficiency and high safety during use.

Description

technical field [0001] The invention relates to a pesticide insecticide, in particular to a preparation method of acetamiprid water-dispersible granules. technical background [0002] Water-dispersible granules (WDG) are a new type of pesticide formulation developed in Europe and the United States in the early 1980s. The International Federation of Pesticide Industry Associations (GIFAP) defines it as: granules used after disintegration and dispersion in water. WDG is mainly composed of active ingredients of pesticides, dispersants, wetting agents, binders, disintegrants and fillers, with a particle size of 200-500um. It can quickly disintegrate and disperse after entering water to form a high-suspension dispersion system. [0003] Pesticide formulations such as emulsifiable concentrates, wettable powders, powders, and granules account for about 80% of the total preparations in my country. With the development of processed dosage forms, the shortcomings of traditional dosag...
