Water-resistant putty powder for interior walls and preparation method thereof

The present application relates to the technical field of building materials, and specifically discloses a water-resistant putty powder for interior walls and a preparation method thereof. A water-resistant putty powder for interior walls, the raw materials of which include: sulphoaluminate cement, nano-heavy calcium powder, silica fume, double MOF composite nanotubes, modified diatomaceous earth, polypropylene fiber, nano-titanium dioxide, defoaming agent, dispersant and mildew inhibitor. The double MOF composite nanotubes are obtained by loading copper trimesic acid in the inner cavity of halloysite nanotubes and loading dimethylimidazole cobalt on the outer wall; the modified diatomaceous earth is obtained by modifying diatomaceous earth with stearic acid. The water-resistant putty powder for interior walls of the present application uses double MOF composite nanotubes as the core functional material, and under the synergistic effect of multiple components, it effectively enhances the water resistance and air permeability of the putty layer.
