That remaining is moderate-speed mixer 1000r/min -1500r/min；
Or water-repellent preservation colored paint the preparation method is as follows:
It takes the multiple self-crosslinking core-shell type lotion of 100 parts of room temperatures in dispersion cylinder, substrate wetting is added under moderate-speed mixer
0.1-0.5 part of agent, 0.2-0.5 part and 1-5 parts of wetting dispersing agent of levelling agent, after stirring 15min-20min respectively, improve and turn
Speed carries out high-speed stirred and 0.1-0.25 part of half defoaming agent is added, and stirs 20min or more, and mill base is added, and stirs 30min or more,
Then 0.1-0.25 part of remaining defoaming agent, 0.2-0.5 part of total defoaming agent is added；Then sequentially add corrosion inhibiter 1.0-
3.0 parts, 1-4 parts and 0.1-1 part of thickener of coalescing agent, stir 30min or more, and filtering and discharging is placed an evening at room temperature, obtained
To water-repellent preservation colored paint；Moderate-speed mixer is 1000r/min -1500r/min, and high-speed stirred is the r/ of 2500 r/min -3000
min。
