The invention discloses a preparing method for scaling powder for soldering paste and an ultrasonic rapid cooling system of the preparing method. According to the preparing method for the scaling powder, modified rosin is heated and melted at the temperature ranging from 140 DEG C to 150 DEG C, then, a solvent is slowly added in the melted modified rosin, the temperature is kept to range from 130DEG C to 140 DEG C, high-speed emulsification is conducted for 30 min, and the emulsification speed ranges from 3,000 rpm to 4,000 rpm; then an active agent and a thixotropic agent are added, the temperature is kept to range from 120 DEG C to 130 DEG C, high-speed emulsification is conducted for 20 min, and the emulsification speed ranges from 3,000 rpm to 4,000 rpm; emulsified materials are poured into a glass container and then placed in cooling water subjected to the ultrasonic action to be rapidly cooled, and cooling is conducted till the materials are solidified. The prepared scaling powder for the soldering past
