[0040] A preparation method of a two-way high-adhesion exterior wall primer coating, the specific steps are as follows:
[0041] 1) Add 15-18 parts of deionized water into the dispersion tank, then add 0.4-0.7 parts of dispersant, 0.1-0.3 parts of wetting agent, 0.1-0.3 parts of defoamer, 0.1 ~0.3 parts of hydroxyethyl cellulose, 0.1~0.3 parts of water-based multifunctional additives, stirring for 3~5 minutes;
[0042] 2) Then increase the speed to 800-1200r / min, add 4-7 parts of rutile titanium dioxide, 2-5 parts of mica powder, 22-28 parts of 500-mesh heavy calcium, 2-4 parts of 700-mesh heavy calcium, and then Increase the speed to 1400~1600r / min and disperse for 15~20min;
[0043] 3) Then check the fineness, when the fineness is ≤60μm, reduce the speed to 500-800r / min, add 3-6 parts of high Tg emulsion, 36-42 parts of low Tg emulsion, 1-1.5 parts of antifreeze, 1.6- 2.4 parts of film-forming aids, 0.1-0.3 parts of defoamers, 0.2-0.6 parts of anti-corrosion and anti-mold ...
