example 1

[0021] The low cement-based finishing mortar for external wall insulation is composed of a mixture and water at a mass ratio of 100:20, wherein the mixture consists of 8 parts by mass of white cement, 14 parts by mass of quartz powder, 4 parts by mass of dispersible latex powder, 0.8 parts by mass of nanoscale rubber powder, 1 part by mass of reinforcing agent (composed of calcium formate and polycarboxylate superplasticizer at a ratio of 2:1), 14 parts by mass of heavy calcium, 38 parts by mass of 40-70 mesh colored sand, 200 mesh colored sand It consists of 19 parts by mass of sand, 2 parts by mass of cellulose ether, and 1 part by mass of water repellent.

[0022] Before use, the above-mentioned mixture is placed in a mixer for pre-mixing, and the mixing time is not less than 2 minutes. When in use, first add water, and then use an electric mixer to add the evenly mixed mixture while stirring. After fully stirring for 5 minutes, the slurry is left to stand for 5 minutes, a...

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. H...
