Add 18 parts of polyether and 2.5 parts of crosslinking agent to the reaction vessel, raise the temperature to 50 ℃, and slowly add 8.5 parts of 2,4-dimethyldiisocyanate. After adding, react at 80 ℃ for 2-3 hours, cool to 50-55 ℃, add tertiary amino compounds, and emulsify with acid solution to obtain.
