preparation example Construction

[0011] The present disclosure provides a method for preparing a microcapsule suspension-suspending agent containing abamectin and etoxazole. The preparation method may include the following steps: (1) mixing the first solution and the second solution uniformly to obtain the first Materials; wherein the first solution contains benzoyl peroxide and methyl methacrylate; the second solution contains abamectin EC; the weight ratio of the first solution to the second solution is 1: (5-10); (2) Mix the first material and water uniformly, and stir to obtain the second material; the weight ratio of the first material to water is 1: (1-5); (3) Add NaHSO to the second material 3 Solution, mixed uniformly to obtain the third material; the second material contains benzoyl peroxide and NaHSO 3 NaHSO in solution 3 The weight ratio is 1: (1-3); (4) The third material is cured and polycondensed to obtain a cured polycondensation product; a pH regulator is added to the cured polycondensation prod...

Embodiment 1

[0039] Benzoyl peroxide (BPO) is dissolved in methyl methacrylate (MMA) and mixed uniformly, wherein the weight ratio of BPO to MMA is 1:1000.

[0040] Abamectin, N-methylpyrrolidone, calcium dodecyl benzene sulfonate, and sorbitan monostearate polyoxyethylene ether are mixed uniformly to obtain abamectin EC, wherein the avermectin The mass ratio of mycin to N-methylpyrrolidone, calcium dodecylbenzenesulfonate, and sorbitan monostearate polyoxyethylene ether is 1:8.5:1:1.5:0.4.

[0041] The obtained BPO / MMA solution and abamectin EC are mixed uniformly to obtain the first material, wherein the weight ratio of the BPO / MMA solution and abamectin EC is 1:100; at room temperature, the first material A material is mixed with water, and stirred at 50r / min for 3min to obtain the second material, wherein the weight ratio of the first material to water is 1:1; at room temperature, 0.01% by weight of NaHSO 3 The solution was slowly added dropwise to the second material at a rate of 1 drop ev...

Embodiment 2

[0045] Benzoyl peroxide (BPO) was dissolved in methyl methacrylate (MMA) and mixed uniformly. The weight ratio of BPO to MMA was 1:1000.

[0046] The preparation method of abamectin EC is the same as in Example 1.

[0047] The obtained BPO / MMA solution and abamectin EC are mixed uniformly to obtain the first material, wherein the weight ratio of the BPO / MMA solution and abamectin EC is 1:200; at room temperature, the first material A material is mixed with water, and stirred at 100r / min for 3min to obtain the second material; the weight ratio of the first material to water is 1:0.8; at room temperature, 0.01% by weight of NaHSO 3 The solution was slowly added dropwise to the second material at a rate of 1 drop every 4-5 minutes, while stirring it at a rate of 100r / min to obtain a third material, wherein the BPO in the second material With NaHSO 3 NaHSO in solution 3 The weight ratio is 1:1.5; at room temperature, the third material is cured and polycondensed for 2 hours to obtain a...

Abstract

The invention discloses a micro-capsule suspension-suspending agent containing abamectin and etoxazole and a preparation method of the micro-capsule suspension-suspending agent. The preparation method comprises the following steps: (1) a first solution containing benzoperoxide and methyl methacrylate is mixed with a second solution containing an abamectin emulsifiable concentrate uniformly, and a first material is obtained; (2) the first material is mixed with water uniformly, and after stirring and emulsification, a second material is obtained; (3) a NaHSO3 solution is added to the second material and is mixed uniformly, and a third material is obtained; (4) the third material is subjected to solidified and condensed, a solidified and condensed product is obtained, the pH value of the solidified and condensed product is adjusted to 6-8, and a fourth material is obtained; (5) a dispersing agent is added to the fourth material, and a fifth material is obtained; and (6) the fifth material is mixed with an etoxazole suspending agent uniformly, and the micro-capsule suspension-suspending agent is obtained. The micro-capsule suspension-suspending agent is long in duration of efficacy, and the dosage of a pesticide can be reduced effectively.

Description

Technical field [0001] The present disclosure relates to the technical field of pesticides, in particular to a microcapsule suspension-suspension agent containing abamectin and etoxazole. Background technique [0002] Abamectin is a widely used agricultural or veterinary insecticide, bactericide, and acaricide, and is favored by the majority of pesticide manufacturers and farmers. However, abamectin photolysis is extremely strong. Due to ultraviolet light irradiation on the surface of plants and soil, the medicament quickly decomposes and becomes ineffective, thus reducing its control effect. In addition, abamectin preparations on the market are mainly emulsifiable concentrates and contain a large amount of organic solvents, which wastes resources and pollutes the environment. Therefore, microencapsulation of abamectin is one of the important ways to solve the above problems. However, the preparation of abamectin microcapsule suspension by traditional methods such as interfacia...
