Problems solved by technology

Due to poor measurement accuracy, it is difficult to stir evenly during mass production, and at the same time, due to uneven dispersion of toner and unstable coloring, the color difference of the decorative surface is serious.
In addition, the facing mortar also has defects such as pan-alkali and cracks.
These defects, especially chromatic aberration, have seriously affected its promotion and application
[0004] At present, when the decorative mortar is used to decorate the exterior wall of the building at home and abroad, the exterior wall primer and latex paint are painted on the surface. Because the latex paint can be accurately toned, the defect of color and color difference is solved, but this makes the construction of the decorative mortar Increased process, increased cost, changed decorative effect, and completely lost the original air permeability and decorative style of decorative mortar

Abstract

The invention discloses attapulgite finishing coating mortar and a preparation method thereof and relates to the technical field of building materials. The finishing coating mortar is prepared from acomponent A and a component B; during use, the component A and the component B are mixed according to the ratio; the component A is prepared from the following raw materials: modified epoxy resin, 42.5 white Portland cement, a quartz sand mixture, heavy calcium carbonate powder and nanometer aluminum oxide; and the component B is prepared from the following raw materials: modified attapulgite, alkali resistant acrylic emulsion, texanol, color paste and natural vegetable oil. According to the preparation method disclosed by the invention, by carrying out modifying treatment on the epoxy resin and the attapulgite, weather fastness and compressive strength of the finishing coating mortar are enhanced; and the preparation method has the advantages of low cost, simple process, no pollution andsuitability for industrial production.

Description

Technical field: [0001] The invention relates to the technical field of building materials, in particular to an attapulgite decorative mortar and a preparation method thereof. Background technique: [0002] Mortar is a commonly used building material, generally used in masonry and plastering works. Mortar is made by mixing cementitious materials (cement, lime, clay, etc.) and fine aggregate (sand) with water. According to the composition materials, it can be divided into: ①lime mortar: made of lime paste, sand and water according to a certain ratio, generally used for masonry and plastering layers that do not require high strength and are not subject to moisture; ②cement mortar: made of Cement, sand and water are made according to a certain ratio, and are generally used for masonry, walls or floors in wet environments or in water; ③Mixed mortar: Add appropriate admixtures such as fly ash, It is made of diatomite to save the amount of cement or lime and improve the workabil...
