Efforescence resistant colored wall finishing mortar

Abstract

The invention discloses efforescence resistant colored wall finishing mortar, which is prepared from the following raw materials in percentage by weight: 12%-20% of high-alumina cement, 5%-10% of white cement, 65%-75% of quartz sand, 0.1%-3% of inorganic pigment, 2%-4% of active nanometer SiO2, 2%-4% of redispersible powder, 0.1%-1% of a defoamer, 0.1%-1% of a wood fiber and 0.1%-0.6% of cellulose ether. By adopting a binary gelled material taking the high-alumina cement as a main material and the white cement as an auxiliary material, and matching with the active nanometer SiO2 and the redispersible powder as additives, the strength of the finishing mortar is ensured, the problem of efforescence of the finishing mortar can be effectively solved, the overall decorative effect of the finishing mortar is greatly improved, and the late wall maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of building exterior wall coatings, and in particular relates to a colored finishing mortar without efflorescence phenomenon during use. Background technique [0002] Color facing mortar is a new type of inorganic powdery decorative material, which has been widely used in the interior and exterior wall decoration of buildings instead of paint and ceramic tiles in developed countries. It is refined from inorganic gelling materials, fillers, high-quality mineral aggregates, various additives and natural mineral pigments. It is not easy to stick to dust and has self-cleaning ability. Anti-shrinkage, low maintenance cost, good durability and other characteristics, it is a completely healthy green decorative material. The thickness of the coating is generally between 1 and 3mm, and can be processed into various styles of textured surfaces, with three-dimensional and real flexible texture textures and rich and va...

AI Technical Summary

Problems solved by technology

The efflorescence of the decorative mortar is formed in this way, and the white powder crystallization on the surface of the decorative mortar after toning seriously affects the decorative effect of the exterior wall, making the appearance quality of the wall deteriorate.
