Abstract

The invention discloses putty powder for an exterior wall and a preparation method thereof, belonging to the field of building coatings. The putty powder for the exterior wall is prepared from the following raw materials in parts by weight: 300-400 parts of ground calcium carbonate, 250-350 parts of white cement, 350-500 parts of quartz sand, 12-30 parts of latex powder, 4-5 parts of cellulose ether, 0.1-2 parts of starch ether and 1-3 parts of magnesium aluminum silicate. The thickness of the exterior wall putty powder can be finely adjusted; tiles pasted by using the exterior wall putty powder are high in flatness; and the putty powder is strong in heat preservation perfromance, good in constructability and high in viscosity.

Description

technical field [0001] The application relates to an exterior wall putty powder and a preparation method thereof, belonging to the field of architectural coatings. Background technique [0002] Putty powder for exterior walls is also called cement, which is used for viscose for tiling. Because the thickness variability, bulkiness, and workability of the existing cement cannot meet the adjustment thickness. When workers use exterior wall putty to stick tiles, if they do not grasp the amount, it is difficult to adjust the thickness of exterior wall putty after the wall is installed, especially for new workers. Contents of the invention [0003] In order to solve the above problems, an exterior wall putty powder with improved comprehensive performance and a preparation method thereof, especially a putty powder with improved construction performance, are provided. The thickness of the putty powder for external walls can be fine-tuned, and the use of the putty powder for exte...
