preparation example Construction

[0015] The preparation process of all the following tribenuron-methyl water-dispersible granules is as follows:

[0016] 1. Select raw materials according to the formula and mix them;

[0017] 2. After the above mixture is ultrafinely pulverized by a jet mill, mother powder is obtained;

[0018] 3. The mother powder is kneaded and granulated with water;

[0019] 4. Dry the particles at 65 degrees;

[0020] 5. Screen the dried granules to obtain trisulfuron-methyl water-dispersible granules.

example 1

[0021] Example 1, take by weighing 97% tribenuron-methyl former powder 78.9%, dispersant 5%, wetting agent 4%, emulsifier 2.5%, disintegrant 3%, stabilizer 3%, all the other are filler; Wherein, wetting agent The wetting agent adopts LH-14, and the dispersant adopts LH-AS. The above raw materials are sequentially mixed, pulverized, granulated, dried and screened to obtain the tribenuron-methyl water-dispersible granule.

[0022] The tribenuron-methyl water-dispersible granule has been tested to have an active ingredient content of 75%, a suspension rate of 92%, a disintegration time of less than 108 seconds, and a dispersion rate of 92%. The accelerated thermal storage stability is qualified and meets the requirements of soluble water-dispersible granules. quality technical indicators.

example 2

[0023] Example 2, take by weighing 97% tribenuron-methyl former powder 78.9%, dispersant 5.1%, wetting agent 4.1%, emulsifier 2.6%, disintegrating agent 3.1%, stabilizer 3.1%, all the other are filler; Wherein, wetting agent The wetting agent adopts LH-14, and the dispersant adopts LH-AS. The above raw materials are sequentially mixed, pulverized, granulated, dried and screened to obtain the tribenuron-methyl water-dispersible granule.

[0024] The tribenuron-methyl water-dispersible granule has been tested to have an active ingredient content of 75%, a suspension rate of 91.7%, a disintegration time of less than 106 seconds, and a dispersion rate of 91.8%. The accelerated heat storage stability is qualified and meets the requirements of soluble water-dispersible granules. quality technical indicators.

Abstract

The invention discloses a tribenuron-methyl water dispersible granule. The tribenuron-methyl water dispersible granule comprises tribenuron-methyl raw powder, a wetting agent, a dispersing agent, a disintegrating agent, an emulsifying agent, a stabilizing agent and filler, wherein the content of the tribenuron-methyl raw powder is 78.9%, the content of the dispersing agent is 5%-5.5%, the contentof the wetting agent is 4%-4.5%, the content of the emulsifying agent is 2.5%-3%, the content of the disintegrating agent is 3%-3.5%, the content of the stabilizing agent is 3%-3.5%, and the balance of the filler. The prepared water dispersible granule is 75% tribenuron-methyl water dispersible granule, the content of active components is high, the environmental pollution is small, the disintegrating speed is high, the dispersing performance is good, and the heat storage performance is stable.

Description

technical field [0001] The invention relates to an agricultural water-dispersible granule, in particular to a tribenuron-methyl water-dispersible granule. Background technique [0002] Tribesulfuron-methyl technical is generally made into wettable powder for use. Due to the serious dust pollution in the process of processing and use of wettable powder, it is very harmful to the environment and human health, and the effective utilization rate is low. Contents of the invention [0003] In order to solve the above technical problems, the invention provides a tribenuron-methyl water-dispersible granule. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A kind of tribenusulfuron-methyl water-dispersible granule, comprising tribenusulfuron-methyl former powder, wetting agent, dispersant, disintegrant, emulsifier, stabilizer and filler, wherein the content of chlorimuron-methyl former powder is 78.9%, dispersing Th...
