The nano modified Portland cement base facing mortar comprises the following components in percent by weight: 12-17 percent of cement, 3-8 percent of mineral mixture, 0.2-0.6 percent of nano materials, 8-12 percent of ground calcium carbonate, 60-70 percent of quartz sand, 1.5-2.2 percent of latex powder, 0.6-1 percent of cellulose ether, 0.4-1 percent of pigment and 0.2-0.4 percent of other additives. The nano modified Portland cement base facing mortar solves the problem that the Portland cement base facing mortar is apt to be efflorescent and be stained, has the advantages of good construction performance, high construction efficiency, good compatibility and match with various base materials, uniform color, higher strength, good weather resistance, good air permeability, good waterproof performance, low cost and the like, and can be particularly used as a facing decoration material for external heat insulation systems of exterior walls of buildings.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of accumulation of salt in the surface soil not in use, have nano modification silicate cement base facing mortar of good contamination resistance and weathering resistance and preparation method thereof simultaneously.
Background technology
Facing mortar is a kind of novel wall finishing material, compares with the organic coating finishing material, has good weather resistance, can reduce the expense that wall facing is safeguarded renovation; Compare with the tile decorative surface material, facing mortar thickness is merely 1～5mm, and is in light weight, can significantly reduce the load of outer wall heat insulating system, during especially as the Highrise buildings facing, can avoid because of ceramic tile that negative blast the occurs phenomenon that drops.In developed country, facing mortar extensively replaces coating and ceramic tile to be applied to the wall body decoration of buildings.But also there are some places not fully up to expectations in facing mortar in applying, and distinct issues are to be prone to the accumulation of salt in the surface soil.The accumulation of salt in the surface soil can not cause facing mortar significantly to destroy usually, but can influence the decorative effect of facing mortar, and promptly produces in the very short time after the buildings of being everlasting comes into operation.
Both at home and abroad the investigator has also carried out a series of researchs aspect the facing mortar accumulation of salt in the surface soil improving, and involved improvement method mainly concentrates on several aspects: with the most of replacement of aluminate cement even replace silicate cement fully; Reduce the silicate cement consumption, increase the polymkeric substance volume; Add accumulation of salt in the surface soil suppressor factor; Do clear finish on the facing mortar surface and handle, produce hydrophobic membrane,, stop Ca (OH) with isolated from atmosphere
2With CO
2Reaction.
The present invention is on main gelling material and the basis than the low-grade polymer volume using silicate cement, does not add accumulation of salt in the surface soil suppressor factor, cover is not done on the mortar surface and is handled, only through adopting nanometer SiO
2Carry out the accumulation of salt in the surface soil performance that modification improves facing mortar with Adding Mineral Admixtures (slag, metakaolin).As everyone knows, the Ca (OH) of silicate cement hydration generation
2Be the main cause of the facing mortar accumulation of salt in the surface soil, Ca (OH)
2Be prone to pore water migrate to the mortar surface and with airborne CO
2Reaction and form white CaCO
3Deposition, Na in addition
+, K
+, SO
4 2-Also can migrate to the mortar surface bonding and separate out the formation white precipitate, these white masses are distributed in the facing mortar surface unevenly, will influence its decorative effect.The slag of admixture, metakaolin and nanometer SiO among the present invention
2Can consume the Ca (OH) that generates in the cement hydration process on the one hand
2, reduce the source that the accumulation of salt in the surface soil produces; Can also improve the density, particularly particle diameter of mortar nanometer SiO on the other hand at nanoscale
2Can stop up the micro-pore in the mortar, reduce the passage of ion to external migration; In addition, nanometer SiO
2Also have the not available good characteristic of macro-scale material, can significantly improve the weathering resistance and the contamination resistance of facing mortar.
Summary of the invention
For overcoming the difficult problem that the cement based facing mortar is prone to the accumulation of salt in the surface soil, is prone to contamination; And lifting wall facing materials ' durability and life-time service performance; The object of the present invention is to provide a kind of cost lower, be suitable for the especially nano modification silicate cement base facing mortar and preparation method thereof of external thermal insulation system of body of wall; This system than the low-grade polymer volume, not admixture accumulation of salt in the surface soil suppressor factor, do not do under the condition that cover handles; With silicate cement is main gelling material, through Adding Mineral Admixtures and employing nanometer SiO
2Carry out modification, reaching facing mortar does not in use have the appearance of accumulation of salt in the surface soil phenomenon, has the good contamination resistance and the purpose of weathering resistance simultaneously.
