External wall putty powder and preparation method thereof

Abstract

The invention relates to external wall putty powder and a preparation method thereof and aims at providing the external wall putty powder with good weather resistance and strong adhesion force and a preparation method thereof. The external wall putty powder comprises the following components in parts by weight: 300-500 parts of white cement, 50-200 parts of organic calcium, 300-500 parts of heavy calcium carbonate powder, 20-40 parts of emulsion powder, 2-5 parts of a water-retaining agent, 2-5 parts of wood fiber, 2-5 parts of a thixotropic agent, 1-3 parts of a water reducing agent and 0.5-1.5 parts of starch ether. The preparation method of the external wall putty powder comprises the following steps of: adding the heavy calcium carbonate powder into a stirrer to be uniformly stirred, then adding the white cement, the organic calcium, the emulsion powder, the water-retaining agent, the wood fiber, the thixotropic agent, the water reducing agent and the starch ether into the stirrer, and uniformly and evenly stirring to obtain the external wall putty powder. The external wall putty powder can be used just by adding an appropriate amount of water and uniformly stirring. The preparation method is simple; and the external wall putty powder prepared by using the preparation method has the advantages of water resistance, alkali resistance, high adhesion force, good filling property and good air permeability, and is easy to shave.

Description
