Embodiment Construction

[0006] An example is given below to describe in detail.

[0007] Weigh respectively 180 grams of emamectin benzoate technical material, 70 grams of β-cyclodextrin, 150 grams of nonylphenol polyoxyethylene ether NP40 surfactant, sodium dodecylsulfonate ABS- 80 grams of Na surfactant, 250 grams of sodium bicarbonate, 270 grams of anhydrous citric acid, a total of 1000 grams for subsequent use, the percentages of each component accounting for the total weight are 18%, 7%, 15%, 8%, 25%, 27% %, totaling 100%. When making, first mix the former medicine of 180 grams of emamectin benzoate with 70 grams of β-cyclodextrin and 80 grams of sodium dodecylsulfonate ABS-Na surfactant in the 50 ℃ water, using a high-pressure homogenizer at 400 kg / cm 2 Stir and homogenize under high pressure; send the homogenized above-mentioned liquid mixture into a spray drying tower for spray drying to make a composite master drug; heat-melt 150 grams of nonylphenol polyoxyethylene ether NP40 surfactant i...

Abstract

The invention discloses a methylamino avermectin benzoate soluble particle agent and preparing method in the pesticide product domain, which comprises the following parts: methylamino avermectin benzoate original-drug, beta-cyclodextrin, nonyl phenol polyoxyethylene ether NP40 surface activator, sodium dodecylbenzene sulfonate ABS-Na surface activator, sodium bicarbonate and anhydrous citrate according to certain weight percentage. The manufacturing method comprises the following steps: blending methylamino avermectin benzoate original-drug, beta-cyclodextrin and ABS-Na surface activator in the water, homogenizing under high-pressure, spraying, drying, preparing composite mother drug, dissolving NP40 surface activator to blend with sodium bicarbonate and anhydrous citrate, obtaining plastic agent, squeezing into column shaped particle, drying in the vacuum to produce the drug.

Description

technical field [0001] The invention belongs to a pesticide preparation and a manufacturing process thereof, and mainly relates to a green, high-efficiency emamectin benzoate soluble granule and a preparation technology. Background technique [0002] At present, most of the pesticide preparations in our country are creamy pesticides, including the creamy pesticides made of emamectin benzoate powdery original drug. This is because emamectin benzyl Salt powder former medicine is insoluble in water, can only be made into emulsifiable product bottling after organic solvent such as toluene, xylene etc. are dissolved and put on the market. When in use, dilute emamectin emamectin emamectin pesticide with water, so that the emulsifiable oil and medicine are dispersed in water for use. Since toluene, xylene and other organic solvents are not only flammable and explosive, but also toxic and harmful, the original medicine of emamectin benzoate, which is non-toxic, harmless and green, ...
