Embodiment 1

[0020] Prepare the ricinoleine water-dispersible granule of 1.0kg mass fraction 1%, the mass ratio of each component is respectively:

[0021] Ricinine 10.53g

Chaku powder 50g

Bentonite 50g

Lignosulfonate 50g

Starch 10g

Isooctanol 5g

The balance is rice husk

[0022] The content of ricinine in the used ricinine former medicine is 95% by mass fraction.

[0023] making process:

[0024] Mix ricinine with tea dry powder, bentonite, lignin sulfonate, starch, isooctyl alcohol and rice husk evenly, pulverize into powder by jet mill, then granulate, dry and sieve to obtain The qualified 1% castorine water-dispersible granule has the advantages of fast disintegration speed, good dispersibility, and little environmental pollution.

Embodiment 2

[0026] Prepare the ricinoleine water-dispersible granule of 1.0kg mass fraction 10%, the mass ratio of each component is respectively:

Abstract

The invention discloses ricinine water-dispersible granules and a preparation method therefor. The ricinine water-dispersible granules contain the ingredients in percent by mass: 1-50% of ricinine, 5-20% of wetting agent, 5-25% of disintegrating agent, 5-10% of dispersing agent, 1-8% of binder, 0.5-6% of antifoaming agent and the balance of filler. The ricinine water-dispersible granules are prepared through uniformly mixing all the ingredients according to the mass percents of all the ingredients, crushing the mixture into powder by a jet mill, and then, carrying out granulating, drying and sieving. The ricinine water-dispersible granules and the preparation method therefor have the advantages that after the water-dispersible granules are prepared from ricinine, on one hand, the storage and transportation of ricinine pesticides are facilitated, and on the other hand, due to an environment-friendly preparation form, environmental pollution is reduced, and environmental protection is facilitated. Besides, the ricinine water-dispersible granules disclosed by the invention have the characteristics of high disintegrating speed, good dispersity and little environmental pollution.

Description

Technical field: [0001] The invention belongs to the field of pesticides, and in particular relates to a ricinine water-dispersible granule and a preparation method thereof. Background technique: [0002] Ricinine is an alkaloid similar to pyridone, its scientific name is 3-cyano-4-methoxy-1-methyl-2-pyridone, and its molecular formula is C 8 h 8 N 2 o 2 , the molecular weight is 164.16, and the structural formula is as shown in formula 1: [0003] [0004] Pure ricinine is a white needle-like or prismatic crystalline alkaloid with a melting point of 201-205°C and sublimation at 170-180°C and 20667kPa. Castorine is easily soluble in hot water and hot chloroform, has a certain solubility in hot ethanol, and is insoluble in ether, petroleum ether and benzene. The aqueous solution is neutral, and it is not easy to form salt with acid. Its alkaline solution can reduce potassium permanganate and generate hydrocyanic acid at the same time. Ricinine exists in the seeds, s...
