Abstract

The invention relates to environment-friendly putty powder with high strength, bacterium inhibition and water resistance and a preparation method thereof. The putty powder is prepared from the following main raw materials: ground calcium carbonate, ash calcium powder, white cement, redispersible latex powder, modified chitosan, bentonite, diatomaceous earth, nano-titanium dioxide, lignocellulose and hydroxypropyl methyl cellulose. The putty powder has excellent adsorption capability and water resistance, and also has good caking property and permeability; organic and inorganic components are closely combined to reinforce the adhesive force of putty to the wall face, the contraction rate after the putty is dried can be reduced, and wall face cracking can be avoided. The putty powder has strong antibacterial property by adding the modified chitosan and nano-titanium dioxide, can be used for preventing mildew growth and inhibiting bacterium breeding, has high construction performance since the bentonite and diatomaceous earth are added to absorb moisture and moisturize, has excellent adsorbability to adsorb harmful substances and purify air, and provides a healthy living environment to people.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength antibacterial and water-resistant environment-friendly putty powder for walls and a preparation method thereof. Background technique [0002] Putty is a building decoration material that smooths the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. The purpose of applying putty is to fill the pores and depressions on the construction surface and correct the curve deviation of the construction surface, so as to lay a good foundation for obtaining a smooth and uniform paint surface. Therefore, it is required that the putty powder should have good cohesiveness and water resistance to ensure that it will not appear peeling, hollowing, cracking and mildew under the long-term erosion of water vapor in the air, and play a decorative and protective role. However, the existing putty powder has low adhesiven...
