Embodiment 1
[0032] Example 1: 2% Cyazofamida Microcapsule Suspension Concentrate.
[0033] The preparation method of urea-formaldehyde resin prepolymer aqueous solution: dissolve urea into formaldehyde, the weight ratio of urea and formaldehyde is 1:1~1:2.5, adjust the pH value to 8 with sodium hydroxide, and stir at a low speed at 80°C , heat preservation reaction for 2 hours to generate a viscous and transparent urea-formaldehyde resin, add deionized water equal to the total weight of urea and formaldehyde, stir at a low speed, and obtain a transparent urea-formaldehyde resin prepolymer aqueous solution;
[0034] Dissolve 2% Cyazofamid in 5% xylene completely at room temperature, add 5% emulsifier castor oil polyoxyethylene ether and 20% water under stirring condition, and shear at 2000 rpm for 10-20 minutes into a stable O / W emulsion;
[0035] Reduce the shearing speed, add urea-formaldehyde resin prepolymer under stirring condition, then add dilute hydrochloric acid dropwise to adju...
Embodiment 2
[0038] Example 2: 8% Cyazofamida Microcapsule Suspension Concentrate.
[0039] Preparation method of urea-formaldehyde resin prepolymer aqueous solution: dissolve urea into formaldehyde, the weight ratio of urea and formaldehyde is 1:1~1:2.5, adjust the pH value to 8 with sodium hydroxide, stir at a low speed at 70°C , heat preservation reaction for 3 hours to generate a viscous and transparent urea-formaldehyde resin, add deionized water equal to the total weight of urea and formaldehyde, stir at a low speed, and obtain a transparent urea-formaldehyde resin prepolymer aqueous solution;
[0040] Dissolve 8% Cyazofamid in 15% xylene completely at room temperature, add 7% emulsifier styrene-based phenol polyoxyethylene ether and 20% water under stirring condition, and shear 10~ 20 minutes into a stable O / W emulsion;
[0041] Reduce the shearing speed, add urea-formaldehyde resin prepolymer under stirring conditions, then add dilute hydrochloric acid dropwise to adjust the pH ...
