Embodiment 1

[0035] A kind of exterior wall color finishing mortar, its raw material component distribution ratio (percentage by weight) is:

[0036] Ordinary Portland white cement: 20%,

[0037] Quartz sand: 58%,

[0038] Basalt chopped fibers (single filament diameter 13μm, chopped length 6mm): 0.4%,

[0039] Ground calcium carbonate: 10%,

[0040] Vinyl acetate and ethylene copolymer powder: 1%,

[0041] Methyl cellulose ether: 0.1%,

[0042] Iron oxide red: 1%,

[0043] Modified organosilicon water repellent 0.2%,

[0044] fly ash 5%,

[0045] Silicone powder 0.1%,

[0046] Metakaolin 3%,

Abstract

The invention relates to a building material, and in particular relates to an exterior wall color surface decoration mortar and a preparation method thereof. The exterior wall color surface decoration mortar comprises the following raw materials by weight: 20%-30% of white cement, 50%-60% of quartz sand, 0.1%-0.5% of chopped fiber, 10%-20% of heavy calcium carbonate, 0.2%-1% of latex powder, 0.3%-0.5% of cellulose ether, 1%-5% of an inorganic pigment, 0.2%-0.4% of a water repellent, 5%-10% of coal powder ash, 0.1%-0.15% of a defoaming agent, 1%-3% of metakaolin, 0.2%-0.5% of a thixotropic lubricant and 1%-2% of a water reducing agent. The exterior wall color surface decoration mortar has the advantages of crack resistance, weather resistance, good ultraviolet resistance, permanent and uniform color, good whiskering resistance, and the like, can be well combined with various inorganic base layer materials, is good in coating density, and can be widely used in the building fields such as exterior wall decoration and the like.

Description

technical field [0001] The invention relates to a building material, in particular to a colored mortar for exterior walls and a preparation method thereof. Background technique [0002] Finishing mortar refers to a kind of physical mixing of aggregates (such as quartz sand), inorganic cementitious materials (such as white cement), and additives (such as polymers, inorganic pigments) that have been dried and screened 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...
