Embodiment 1

[0026] Example 1 90% 2,4-D Choline Water Soluble Granules

[0027] Take 91.8g of 2,4-D choline original drug (content is 98%), add 3.1g of hydrogen phosphate di-salt and 5.1g of dihydrogen phosphate, mix each component fully and uniformly in a kneader, add the total amount of the mixture Knead with 1% of the mass of water, after kneading, granulate at 100°C, and dry at 110°C to obtain 90% 2,4-D choline water-soluble granules, and the obtained water-soluble granules have a high granulation rate , more than 99%, the particles are round, full and not easy to loose.

Embodiment 2

[0028] Example 2 85% 2,4-D Choline Water Soluble Granules

[0029] Take 86.7g of 2,4-D choline original drug (content is 98%), add 5g of bicarbonate, 1g of borate and 7.3g, after fully and uniformly mixing each component in a kneader, add the total mass of the mixture Kneading with 5% of water, after kneading, granulate at 90°C, and dry at 90°C to obtain 85% 2,4-D choline water-soluble granules, the obtained water-soluble granules have a high granulation rate, More than 99%, the particles are round, full and not easy to loose.

Embodiment 3

[0030] Example 3 70% 2,4-D Choline Water Soluble Granules

[0031] Take 71.4g of 2,4-D choline original drug (content is 98%), add 28.6g of carbonate, after fully and uniformly mixing each component in a kneader, add 11% of the total mass of the mixture to knead After kneading, granulate at 80°C and dry at 65°C to obtain 70% 2,4-D choline water-soluble granules. Whole, full, not easy to loose.

Abstract

The invention discloses 2,4-D choline water-soluble granules. The 2,4-D choline water-soluble granules comprise the components in percentage by weight: 5-99.5% of 2,4-D choline and the balance of water-soluble packing. The invention also discloses a preparation method of the 2,4-D choline water-soluble granules. The preparation method comprises the steps of: mixing the 2,4-D choline and the water-soluble packing, kneading, extruding, pelletizing and drying to obtain the 2,4-D choline water-soluble granule product, effective constituents of which are up to 99.5%. The preparation method is simple in process, economic and safe; hazardous chemical substances are not used in the whole production process, no dust is generated, and organic solvents are not needed; the preparation method is environment-friendly and easy in control and operation; and safety factors of the preparation method are high.

Description

Technical field [0001] The present invention involves a pesticide herbicide and its preparation methods. Specifically, it involves a 2,4-D choline water-soluble granules (that is, water-soluble particles) and its preparation methods. Background technique [0002] 2,4-D choline is a selective internal internal absorbent hormone herbicide, which is mainly used in grain crops, coniferous trees, non-cultivated land, pasture, and lawn to prevent the annual and perennial broad-leaved weedEar, purslane, purslane, big nest vegetables, Persian mother -in -law, sowing mother Artemisia, etc.Most broad -leaved crops, especially cotton, are very sensitive to this type of herbicide, and can also be used as soil treatment agents. It is applied before the soybeans are sown.2,4-D choline has the same effect and environmental protection advantages as 2,4-D, but also has more other advantages, such as low volatility, less spreading and driftingThe timing is wider. [0003] At present, the main dosa...
