Problems solved by technology

[0007] The efflorescence and color difference seriously affect the overall decorative effect of the facing mortar, which reduces the appearance quality of the facing mortar, and the cracking not only affects the overall aesthetics of the entire facing, but also affects the reinforcement effect of the wall where the facing is located. Therefore, Urgent improvement
[0008] Aiming at the above phenomenon, patent CN 104016633 B discloses a kind of exterior wall color facing mortar and its preparation method. The facing mortar is composed of the following raw materials in weight percentage: 20%-30% of white cement, 50%-60% of quartz sand %, chopped fiber 0.1%~0.5%, heavy calcium carbonate 10%~20%, latex powder 0.2%~1%, cellulose ether 0.3%~0.5%, inorganic pigment 1%~5%, water repellent 0.2% %~0.4%, fly ash 5%~10%, defoamer 0.1%~0.15%, metakaolin 1%~3%, thixotropic lubricant 0.2%~0.5

Abstract

The invention relates to a colored decorative mortar, which comprises the following raw materials in parts by weight: 500 to 600 parts of quartz sand, 80 to 120 parts of high-alumina cement, 40 to 60parts of heavy calcium carbonate powder, 120 to 150 parts of light calcium carbonate, 40 to 60 parts of hydrated lime powder, 30 to 50 parts of an admixture, and 4 to 10 parts of a pigment. The colored decorative mortar has the advantages of various colors, crack resistance, impermeability, weather resistance, durability and alkali burnout resistance and the like.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a colored decorative mortar. Background technique [0002] Finishing mortar refers to a kind of physical mixing of dried and screened aggregate (such as quartz sand), inorganic cementitious material (such as white cement), additives (such as polymer, inorganic pigment) and so on in a certain proportion. Granular or powdery, transported to the construction site in bags or in bulk, and can be used directly after mixing with water. There are many colors of facing mortar, which are generally used on the wall surface for interior and exterior wall decoration. It is suitable for the exterior wall decoration of high-end real estate and villas and the final decoration layer of entertainment venues, restaurant lights, personalized walls, exterior walls, and external insulation systems. [0003] Compared with conventional facing materials, facing mortar has the following advantages: [...
