A kind of white plaster decorative wall material with self-cleaning function and its preparation and application

Abstract

The invention discloses a preparation method of a white stucco decorative wall material with a self-cleaning function. The preparation method comprises the following steps: firstly adding redispersible latex powder, cellulose ether, a defoaming agent, a lubricating agent and crystal whisker into a conical twin-screw mixer, mixing and stirring, then adding mica powder, white cement and sepiolite powder into the material obtained in the former step, and then adding titanium dioxide into the material obtained in the former step; then adding quartz powder and quartz sand into the material obtained in the former step, stirring and mixing to obtain the white stucco decorative wall material. A material formula adopted by the invention, and especially a grading uniformly-mixing preparation procedure adopted during preparation, have good beneficial effects: the stucco decorative wall material effectively overcomes the defects that the conventional artistic paint, texture paint, real-stone paint, latex paint and the like have low hardness of coating surfaces and the coating surfaces cannot be polished.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a white plaster decorative wall material with self-cleaning function used on building exterior walls. Background technique [0002] At present, the existing architectural decorative coating technologies, including art coatings, texture coatings, real stone paints, and latex paints, all have the defects of low hardness on the coating surface and the coating surface cannot be polished; especially when it is necessary to make stone-like pattern textures Or when the effect of texture is obvious, because the surface of the coating is not smooth, it is easy to attach dust and dirt, which makes the surface of urban buildings obvious after two or three years. Stains will seriously affect the appearance of the city. Dust and dirt adhere to the decorative coating for a long time, and harmful substances such as carbon monoxide and sulfur dioxide penetrate into the interior ...
