Embodiment 190

[0022] Embodiment 190% terbuthine water-dispersible granules

[0023] Terbutylazine 90%, dispersant sodium polycarboxylate 1.33%, alkylphenol sulfonate sodium 1.33%, calcium lignosulfonate 1.33%, wetting agent a-sulfo fatty acid methyl ester 0.83%, a-olefin sulfonic acid Sodium 0.83% and fatty amide N-methyl taurine sodium salt 0.83%, disintegrant ammonium sulfate 0.5%, diammonium hydrogen phosphate 0.5%, light calcium carbonate make up 100%.

[0024] After the above-mentioned ingredients are fully mixed, carry out ultra-fine airflow pulverization to obtain a 750-mesh fine powder, and then knead the obtained fine powder with an appropriate amount of water (1-5% of the fine powder mass, the same below) in a kneader, It is granulated by an extrusion granulator, and dried in a fluidized fluidized bed at 60°C to obtain 90% terbutyzine water-dispersible granules.

Embodiment 260

[0025] Embodiment 260% terbuthine water-dispersible granules

[0026] 60% terbutyzine, 1.33% sodium polycarboxylate dispersant, 1.33% sodium alkylphenol sulfonate, 1.33% calcium lignosulfonate, 0.83% wetting agent a-sulfo fatty acid methyl ester, a-olefin sulfonic acid Sodium 0.83% and fatty amide N-methyl taurine sodium salt 0.83%, disintegrant ammonium sulfate 0.5%, diammonium hydrogen phosphate 0.5%, light calcium carbonate make up 100%.

[0027] After the above-mentioned ingredients are fully mixed, carry out ultra-fine jet crushing to obtain 750-mesh fine powder, and then knead the obtained fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and fluidize in boiling Dry in bed at 60°C to get 60% terbuthine water dispersible granules.

Embodiment 380

[0028] Embodiment 380% terbuthine water-dispersible granules

[0029] Terbutylazine 80%, dispersant sodium polycarboxylate 1.33%, sodium alkylphenol sulfonate 1.33%, calcium lignosulfonate 1.33%, wetting agent a-sulfo fatty acid methyl ester 0.83%, a-olefin sulfonic acid Sodium 0.83% and fatty amide N-methyl taurine sodium salt 0.83%, disintegrant ammonium sulfate 0.5%, diammonium hydrogen phosphate 0.5%, light calcium carbonate make up 100%.

[0030] After the above-mentioned ingredients are fully mixed, carry out ultra-fine jet crushing to obtain 750-mesh fine powder, and then knead the obtained fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and fluidize in boiling Dry at 60°C in the bed to obtain 80% terbuthyrine water-dispersible granules.

Abstract

The invention discloses terbuthylazine-containing water dispersible granules and a preparation method thereof. The terbuthylazine-containing water dispersible granules consist of the following ingredients in percentage by weight: 10%-90% of terbuthylazine, 1%-10% of a dispersing agent, 1%-10% of a wetting agent, 1%-20% of a disintegrating agent and the balance of an inert filler. The preparation method of the terbuthylazine-containing water dispersible granules is simple, convenient to operate, less in energy consumption, and environmentally friendly, and is capable of realizing continuous production; ultramicro airflow grinding is adopted to grind medicines, and the particle diameter of the water dispersible granules is within a range of 680-840 meshes, thereby guaranteeing efficacy of terbuthylazine; an extruding granulation method is utilized, so that the preparation method is simple and practical, is convenient to implement, is applicable to continuous production, and ensures low manufacturing cost and excellent product quality.

Description

technical field [0001] The invention relates to a terbuthine water-dispersible granule, and also relates to a preparation method of the water-dispersible granule and an application of the water-dispersible granule in preventing and controlling weeds, belonging to the technical field of pesticides. Background technique [0002] The development direction of today's pesticide preparation processing technology is mainly manifested in "obtaining the relatively best drug effect with the safest and as few additives as possible, and promoting the development of preparation products with high content". The overall level of research on high-content environment-friendly formulations of water-dispersible granules and suspension concentrates in my country is relatively low, and the original formulations of wettable powder and other high-content products are generally less, and the production processes of the above-mentioned formulations are mostly still For intermittent production, the co...
