Attapulgite finishing coating mortar and preparation method thereof

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...
