Problems solved by technology

The existence of efflorescence and chromatic aberration has always hindered the overall promotion of the finishing mortar system
[0004] In addition, due to the poor fluidity of cement-based decorative mortar, it often requires a high-power mixer to be used during construction. The construction time is long, the work efficiency is low, and the construction cost is increased. In addition, it generates noise during construction. Energy saving, high requirements for workers' technical proficiency

Abstract

The invention discloses a facing mortar, which comprises a glue powder, a thickening agent and a quartz sand, and the facing mortar comprises the following components by mass percent respectively: glue powder 8-10%, thickening agent 0.05-0.1% and quartz sand 65-91%. The invention has the advantages that the facing mortar of the present invention does not contain cement, thereby the whiskering risk is avoided, and the aberration is smaller than that of the cement based facing mortar, and the production and construction control are simple and convenient, and after 2 min of stirring at 450r / min by the mixer, the product can be used, and the construction mode is diversified, and the construction time is substantially shortened, and the requirements of construction environment and worker skill degree are lower than those of the cement based facing mortar. In addition, compared with the traditional cement facing mortar, the facing mortar of the present invention does not contain toxic substances, and the volatility is extremely low, and the product has the advantages of nontoxic side-effects of construction worker and user, moreover the compressive strength and flexural intensity are better than those of the traditional facing mortar.

Description

technical field [0001] The invention belongs to the technical field of building chemical materials, and in particular relates to a 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 addition, compared with cerami...
