Applicants found during the course of the experiment that:
The water resistance of the dry powder paint can be obviously improved by adopting the compounding of the alkali metal silicate powder and the redispersible rubber powder with proper proportion based on the total weight of Gao Naishui parts of the dry powder emulsion paint as 100 parts. If the consumption of the redispersible rubber powder and the alkali metal silicate powder is too small, the prepared dry powder emulsion paint has poor early and long-term film forming, poor water resistance and easy powder falling; if the consumption of the alkali metal silicate powder is excessive, the adverse effect is that the potassium silicate cannot be completely dissolved, the fineness of the system cannot be dispersed, and the method is not suitable for use. If the first powder pack and the second powder pack are mixed, namely the redispersible rubber powder and the potassium silicate powder are mixed together for dispersion, the alkali of the potassium silicate powder can lead the redispersible rubber powder to be incapable of being dispersed and dissolved, so that the prepared emulsion paint has poor fineness and poor water resistance.
Meanwhile, a proper amount of dispersing agent is added to improve the initial film forming performance, and the proper amount of dispersing agent can improve film forming and water resistance in the initial stage; when the dispersant is added too much (for example, when the dispersant is added in 2.0 parts by weight) or too little (for example, when the dispersant is added in 0.5 parts by weight), the water resistance of the dry powder emulsion paint is deteriorated; in addition, the addition of the dispersing agent has obvious effect of improving dry film powder falling. Preferably, the dispersant is added in an amount of 1.2 parts by weight.
