Embodiment 1
[0055] 5% Abamectin B 2 The dosage of each component of the microcapsule aqueous suspension is shown in Table 1.
[0056] Table-1 5% Abamectin B 2 The dosage of each component of the microcapsule aqueous suspension
[0057]
[0058] 5g Abamectin B 2 The original drug is mixed with 20g xylene to dissolve the original drug, then add 2g modified IPDI (Evonik), 3g modified MDI (Bayer) and stir and mix, add emulsifier NP-10 3g, stir to obtain an oil phase; 2700 (Huntsman) was dispersed in 60.7g of deionized water to obtain a water phase; at a shear rate of 10000rpm, the oil phase was poured into the water phase to obtain an oil-in-water emulsion. At 300rpm of the emulsion, add triethylamine dropwise. After the dropwise addition, the system is heated to 50°C, kept warm for 2 hours, and reacted to the end; add 0.1g of thickener, 3g of antifreeze, 0.1g of preservative, and 0.1g of defoamer g, stir and disperse evenly to get 5% Abamectin B 2 Microcapsules in water suspension.
Embodiment 2
[0060] 10% Abamectin B 2 The dosage of each component of the microcapsule aqueous suspension is shown in Table 2.
[0061] Table-2 1% Abamectin B 2 The dosage of each component of the microcapsule aqueous suspension
[0062]
[0063] 10g Abamectin B 2 The original drug, 10g of dichloromethane, and 10g of N,N-dimethyldecylamide were mixed and dissolved, then 8g of modified TDI (Bayer) was added and stirred, and emulsifier AEO-10 3g was added, and stirred evenly to obtain an oil phase; SC (Solvay) was dispersed in 55.8g deionized water to obtain a water phase; at a shear rate of 8000rpm, the oil phase was poured into the water phase to obtain an oil-in-water emulsion. At 300rpm of the emulsion, triethylenetetramine was added dropwise. After the dropwise addition, the system was heated to 60°C, kept warm for 3 hours, and reacted to the end; 1g thickener, 3g antifreeze, 0.1g preservative, and 0.1 g, stir and disperse evenly to get 10% Abamectin B 2 Microcapsules in wate...
Embodiment 3
[0065] 15% Abamectin B 2 The dosage of each component of the microcapsule aqueous suspension is shown in Table 3.
[0066] Table-3 15% Abamectin B 2 The dosage of each component of the microcapsule aqueous suspension
[0067]
[0068] 15g Abamectin B 2 The original drug, 10g N-methylpyrrolidone, and 10g ethyl acetate are mixed and dissolved, then add 2g TDI (Bayer), 6g MDI (Dow) and stir evenly, add emulsifier BY-125 2.5g, stir evenly to obtain an oil phase; NNO was dissolved in 48.2g deionized water to obtain a water phase; at a shear rate of 12000rpm, the oil phase was poured into the water phase to obtain an oil-in-water emulsion. Add glycerol dropwise to the emulsion at 200rpm. After the dropwise addition, the system is heated up to 60°C, kept warm for 4 hours, and reacted to the end; add thickener 0.1g, antifreeze 3g, preservative 0.1g, defoamer 0.1 g, stir and disperse evenly to get 15% Abamectin B 2 Microcapsules in water suspension.
