Veneer mortar for whiskering-resistant outer walls

Abstract

The invention provides a veneer mortar for whiskering-resistant outer walls, into which nano rubber powder is introduced. The rubber powder can retard the cement component from moving toward the coating surface, thereby well solving the problem of whiskering. In one typical embodiment, the veneer mortar is mainly composed of cement, quartz powder, redispersible latex powder, nano rubber powder, filler, natural sand and additives, and a reinforcer is preferably introduced.

Description

technical field

[0001] The invention belongs to the field of building energy-saving materials, in particular to the field of external wall heat preservation, and in particular relates to a facing mortar. Background technique

[0002] Finishing mortar is a general term for wall plastering with decorative effect. It is composed of inorganic cementitious materials, organic cementitious materials, aggregates and various additives, and is used for the decoration of building wall surfaces. Due to its three-dimensional appearance, the finishing mortar has a natural and unique decorative effect, is breathable and crack-resistant, and has good weather resistance, and the coating thickness can reach 1-3mm, which can be processed into various styles of textured surfaces. Finishing mortar is widely used as a material for building interior and exterior wall decoration instead of paint and ceramic tiles in Europe, and it has gradually begun to be applied in other countries and regions.
