Abstract

The invention discloses a rubber powder for facing mortar. The rubber powder comprises acrylic acid emulsion and anhydrous alumina. The invention has the following advantages: a formula for the rubber powder provided by the invention does not contain cement, so the risk of saltpetering is avoided, and color difference of the facing mortar provided by the invention is smaller than that of cement-based facing mortar; anhydrous alumina added in the formula provides mechanical strength, especially anti-compression rupture strength, for the whole system; since the process of hydration of cement is not included in preparation of the rubber powder, it only takes 1 h for preparation of the facing mortar; and requirements on a construction environment and proficiency of a worker by the facing mortar provided by the invention are much lower than requirements by the cement-based facing mortar.

Description

technical field [0001] The invention belongs to the technical field of chemical materials in construction, and in particular relates to a rubber powder for facing mortar. Background technique [0002] With the development of the economy, people have higher and higher requirements for the decoration of the interior and exterior walls of buildings. Traditional latex paint and ceramic tiles can no longer fully meet people's needs. Due to its wide range of color changes, rich surface shapes, and good weather resistance More and more people are welcome, facing mortar is composed of inorganic cementitious materials, fillers, additives and aggregates, and is used for building wall materials and ceiling decoration materials. At present, most of the exterior walls of buildings are used as external insulation layers. Compared with the existing coatings and other organic materials, the finishing mortar has better matching and compatibility with the external insulation system. In addit...
