Problems solved by technology

[0004] At present, the processing method of domestic water-dispersible granules is generally extrusion granulation. The processing process is cumbersome, with many procedures, and it is easy to generate heat during the granulation process. It is difficult to control the production of low-melting point pesticides. Due to the large extrusion force, The produced product is relatively tight and has poor disintegration

Embodiment 1

[0026] Put 120 kilograms of white carbon into the 1000L twin-screw conical mixer, add 31.25 kilograms of molten trinexapac-ethyl through the spray device under stirring, stir and absorb to make master powder, then add 10 kilograms of Morwet-EFW, Morwet D -42512.5 kg, 2.5 kg white sugar, 73.75 kg kaolin. After being evenly mixed, it is pulverized by a jet mill to an average particle size of less than 5 microns; then in a disc granulator, the above-mentioned pulverized material is used as the base material and water is used as a binder for disc granulation. Dried fluidized bed dryer to a moisture content of less than 2.0%, sieve 10 to 120 mesh particles through a shaking sieve, and obtain the product after passing the test.

Embodiment 2

[0028] Put 135 kilograms of white carbon black into the 1000L twin-screw conical mixer, add 62.5 kilograms of molten trinexapac-ethyl through the spray device under stirring, and mix and absorb all the ingredients into master powder, and then add them in sequence LZ / B 10 kg, Reax 88A 15 kg, urea 2.5 kg, diatomaceous earth 25 kg. After being evenly mixed, it is pulverized by a jet mill to an average particle size of less than 5 microns; then in a disc granulator, the above-mentioned pulverized material is used as the base material and water is used as a binder for disc granulation. Dried fluidized bed dryer to a moisture content of less than 2.0%, sieve 10 to 120 mesh particles through a shaking sieve, and obtain the product after passing the test.

Embodiment 3

[0030] Put 150 kilograms of white carbon black into a 1000L twin-screw conical mixer, add 70 kilograms of molten trinexapac-ethyl through a spray device under stirring, and then mix and absorb all of them into master powder, and then add 10 kilograms of tea saponin, PVP K-30 15 kg, sodium chloride 2.5 kg, activated clay 2.5 kg. After being evenly mixed, it is pulverized by a jet mill to an average particle size of less than 5 microns; then in a disc granulator, the above-mentioned pulverized material is used as the base material and water is used as a binder for disc granulation. Dried fluidized bed dryer to a moisture content of less than 2.0%, sieve 10 to 120 mesh particles through a shaking sieve, and obtain the product after passing the test.

[0031] The adsorption equipment used in the above embodiment is a twin-screw conical mixer with a heating jacket and a spray device. The disc granulator used is equipped with a spray device with adjustable flow rate and atomization de...

Abstract

The invention discloses a trinexapacethyl water dispersible granule preparation, which consists of 10 to 30 percent of trinexapacethyl raw medicine, 1 to 10 percent of wetting agents, 1 to 15 percent of dispersing agents, 1 to 10 percent of disintegrating agents, 30 to 60 percent of absorbing agents and 1 to 50 percent of inert carriers. The trinexapacethyl water dispersible granule preparation is produced by adopting a circular disc granulation mode, the kneading and the granulation are integrated into one step, and work procedures are reduced. Obtained products are spherical granules, the appearance is attractive, the flowability is good, the disintegration is fast, the heat generation is avoided in the granulation process, and the method is suitable for the production of low-melting-point raw medicine.

Description

Technical field [0001] The invention relates to a trinexapac-ethyl water dispersible granule and a preparation method thereof. Background technique [0002] Triflux-ethyl is a cyclohexane carboxylic acid plant growth regulator, which regulates plant growth by inhibiting the biosynthesis of gibberellin. Used in cereal crops and winter rape, it can prevent lodging and improve harvest efficiency; used in lawns can reduce the number of trimmings; used in sugarcane can promote maturity. Due to the low melting point of trinexapac-ethyl, which is only 36°C, the current main dosage forms are emulsifiable concentrates and microemulsions, and no water-dispersible granules are available. Emulsifiable concentrates use a large number of environmentally toxic solvents containing benzene rings, and microemulsions also contain more polar solvents that are not easily degradable and a large number of polymer emulsifiers, which are more harmful to the environment and human body. [0003] In accorda...
