Example Embodiment
[0059] Embodiment 1,
[0060] Dissolve 15 parts of chitosan oligosaccharide, 1 part of salicylic acid, 2 parts of potassium phosphate, 0.5 parts of dicyandiamide (DCD), and 5 parts of Tween 60 in 100 parts of deionized water to obtain an aqueous phase;
[0061] 6 parts of Span 60 are dissolved in 200 parts of n-hexane to obtain oil phase I;
[0062] Dissolve 5 parts of IPDI in 50 parts of n-hexane to obtain oil phase II;
[0063] After adding the oil phase I to the water phase, carry out high-speed shear emulsification for 3 minutes, and the rotating speed is 3000 rpm; after obtaining the pre-emulsion, switch to overhead stirring, and evenly add the oil phase II dropwise at a rotating speed of 1000 rpm. After the addition is completed for 5 minutes, switch to 500 rpm for low-speed stirring. The reaction was carried out for 8 h, and the stirring speed was continued at a temperature of 50 °C. The solution was recovered by rotary evaporation, and finally, the concentrated solut...
Example Embodiment
[0067] Example 2
[0068] 15 parts of chitosan oligosaccharide, 1 part of naphthalene acetic acid, 2 parts of potassium sulfate, 0.5 parts of naphthalene acetic acid, 0.3 parts of 3,4-dimethylpyrazole phosphate (DMPP), 2.5 parts of Span 60 and 2.5 parts of Span 80 Dissolve in 100 parts of deionized water to obtain an aqueous phase;
[0069] Prepare 40 parts of cyclohexane to obtain oil phase I;
[0070] Dissolve 0.01 part of MDI in 200 parts of cyclohexane to obtain oil phase II;
[0071] After adding the oil phase I to the water phase, carry out high-speed shear emulsification for 15 minutes, and the rotation speed is 3000 rpm. After obtaining the pre-emulsion, switch to overhead stirring. At the rotation speed of 1000 rpm, add the oil phase II evenly dropwise. After 5 minutes of adding, switch to 500 rpm for low-speed stirring. The reaction was carried out for 8 h, and the stirring speed was continued at a temperature of 50 °C. Finally, the solution is recovered by rotary...
Example Embodiment
[0073] Example 3
[0074] Dissolve 15 parts chitooligosaccharide, 1 part indoleacetic acid, 3 parts potassium silicate, 0.5 parts indoleacetic acid, 0.3 parts potassium azide, 2.5 parts Span 60 and 2.5 parts Span 80 in 100 parts deionized water , get the water phase;
[0075] Prepare 40 parts of biodiesel to obtain oil phase I;
[0076] Dissolve 0.01 part of MDI in 200 parts of biodiesel to obtain oil phase II;
[0077] After adding the water phase to the oil phase I, carry out high-speed shear emulsification for 15 minutes, and the rotation speed is 2000 rpm. After obtaining the pre-emulsion, switch to overhead stirring, and evenly add the oil phase II dropwise at a rotation speed of 1000 rpm. After 5 minutes of addition, switch to a low speed of 500 rpm. The reaction was stirred for 8 h, and the stirring speed was continued at a temperature of 50 °C. The solution was recovered by rotary evaporation, and finally, the concentrated solution was filtered through a 0.22-micron...
