Abstract

The invention discloses an environmental-friendly building inner wall putty powder and a preparation method thereof. The putty powder comprises the following components by the weight percentage: 5-12 percent of light calcium, 18-25 percent of French chalk, 50-60 percent of calcium magnesium powder, 2-4 percent of hydroxyethyl cellulose, 7-12 percent of bentonite, and 1-3 percent of hydroxy propyl methyl cellulose. The putty powder has the advantages of environment protection, health, whiteness, strong cohesion, good water resistance, alkali resistance and adhesion force, swabbing resistance, storage stability, realization of fine, soft and smooth wall surface and durable coating, and is simple in production process, low in cost and excellent in product comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of architectural interior wall decorative coatings, in particular to a novel environment-friendly architectural interior wall putty powder and a preparation method thereof. Background technique [0002] In the interior wall decoration of buildings, the amount of putty powder for interior walls is increasing, and the quality of putty powder directly affects the decorative effect of interior wall painting. The traditional putty powder has low bonding strength and poor water resistance, resulting in defects such as coating cracks, peeling, peeling, and mold growth, and most of them contain glue. There are formaldehyde and other harmful substances in the glue, and the environmental performance is poor. . Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a novel building interior wall putty powder and a preparation method thereof....
