Problems solved by technology

However, at present, when "medicine" and "fertilizer" are mixed together, the combination of active ingredients of pesticide and fertilizer is unstable, which seriously affects the quality and effect of "medicine fertilizer".
Existing pesticide stabilizers include phosphoester stabilizers, phosphite stabilizers, sulfate stabilizers, sulfonate stabilizers, UV absorbers, etc., but these pesticide stabilizers mostly compete with redox reactions and Absorb light of a specific wavelength to ensure the stability of the active ingredients of pesticides. These stabilizers are used in conventional liquid preparations such as emulsifiable concentrates and suspension concentrates. Fertilizers contain inorganic salts and organic matter that are prone to acid-base neutralization reactions with the above-mentioned stabilizers and become invalid. , making the stabilizer ineffective, the effect is not good

Embodiment 1

[0023] Embodiment 1: 1% clothianidin granules

[0024] First prepare 30% clothianidin oil intermediate: mix 29.07 grams of methyl ester oil, 30.00 grams of hydrogenated styrene butadiene copolymer (SEBS), 10.00 grams of OF-7812, disperse and mix evenly, and then add 97% clothianidin 30.93 g of amine was dispersed at high speed for 20 to 30 minutes to obtain a homogeneous oil phase system, and a 30% clothianidin oil intermediate was obtained.

[0025] Use granular urea as the fertilizer carrier, put 92.67 grams of granular urea in the drum stirring device, start stirring, weigh 3.33 g of 30% clothianidin oil intermediate in the urea carrier, stir for 3 minutes, until the oil intermediate is completely and evenly dispersed, add 4.00 g of anti-caking powder, stirred for 2 minutes, until the anti-caking powder is evenly dispersed in the carrier, and the preparation of the 1% clothianidin granule sample is completed. The rotation speed of the stirring equipment was always kept at ...

Embodiment 2

[0036] Embodiment 2: 0.12% thiamethoxam granules

[0037] First prepare 5% thiamethoxam oil intermediate: mix 54.79 grams of methyl ester oil, 30.00 grams of hydrogenated styrene butadiene copolymer (SEBS), and 10.00 grams of OF-7812, disperse and mix evenly, and then add 96% clothianidin 5.21 g of thiamethoxam was dispersed at a high speed for 20 to 30 minutes to obtain a homogeneous oil phase system, and a 5% thiamethoxam oil intermediate was obtained.

[0038] Use granular urea as the fertilizer carrier, put 93.6 grams of granular urea in the drum stirring device, start stirring, weigh 2.40 g of 5% thiamethoxam oil intermediate in the urea carrier, and stir for 3 minutes until the oil intermediate is evenly dispersed on the carrier , add 4.00 g of anti-caking powder, and stir for 2 minutes until the anti-caking powder is evenly dispersed in the carrier, and the preparation of the 1% thiamethoxam granule sample is completed. The rotation speed of the stirring equipment was ...

Embodiment 3

[0049] Embodiment 3: 6% metaldehyde carbaryl granules

[0050] First prepare 36% Metaldehyde carbaryl oil intermediate: mix 27.90 grams of white oil 7#, 30 grams of hydrogenated styrene-butadiene copolymer (SEBS), and 5.00 grams of NP-10, and mix evenly through dispersion. Then add 27.60 grams of metaldehyde and 9.50 grams of carbaryl, and disperse at a high speed for 20 to 30 minutes to obtain a homogeneous oil phase system and obtain a 36% metaldehyde·carbaryl oil intermediate.

[0051] With the organic-inorganic compound fertilizer as the carrier, 73.33 grams of the organic-inorganic compound fertilizer was placed in the drum stirring device, and the stirring was started, and 16.67 g of 36% metaldehyde carbaryl oil intermediate was weighed on the fertilizer carrier, and stirred for 3 minutes until The oil intermediate is uniformly dispersed on the carrier, 10.0 g of anti-caking powder is added, and stirred for 2 minutes until the anti-caking powder is evenly dispersed on th...

Abstract

The invention discloses a pesticide granule stabilizing agent and application thereof. The stabilizing agent belongs to styrene-butadiene segmented copolymers (SBS) and is particularly a hydrogenatedstyrene-butadiene segmented copolymer (SEBS). A utilization method of the stabilizing agent namely the hydrogenated styrene-butadiene segmented copolymer (SEBS) includes that the stabilizing agent namely the hydrogenated styrene-butadiene segmented copolymer (SEBS) is dissolved into an oil phase to organically combine with an emulsifying agent, pesticide active components and a fertilizer carrierto prepare pesticide granules through various granulating processes. The pesticide granule stabilizing agent and application thereof have advantages that simple process and safety in use are realized,and the problem of instability in combination of pesticide effective components and fertilizers can be solved.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a stabilizer for pesticide granules and an application thereof. Background technique [0002] "Medical fertilizer", because of the synergistic effect of "medicine" and "fertilizer" when applied at the same time, is recognized by more and more people and is favored by farmers. However, at present, when "medicine" and "fertilizer" are mixed together, the combination of active ingredients of pesticide and fertilizer is unstable, which seriously affects the quality and effect of "medicine fertilizer". Existing pesticide stabilizers include phosphoester stabilizers, phosphite stabilizers, sulfate stabilizers, sulfonate stabilizers, UV absorbers, etc., but these pesticide stabilizers mostly compete with redox reactions and Absorb light of a specific wavelength to ensure the stability of the active ingredients of pesticides. These stabilizers are used in conventional liquid preparat...
