Description
Technical field
The present invention relates to a kind of wall facing mortar for building.
Background technology
Facing mortar is a kind of novel wall surface finishing material of China from external introduction, it is made up of inorganic coagulation material, filler and aggregate, the decoration that is used for the construction wall surface, because the thermomechanical properties such as springform thermal expansivity of facing mortar are similar to the plastering mortar of external insulation system, so good matching and consistency are arranged with outer heat preservation system.Facing mortar is compared with existing organic coating finish coat, has good weather resistance, can reduce the expense of organic coating product maintenance renovation; Compare with tile decorative surface, facing mortar thickness only is 1-3mm, and is in light weight, can reduce the load of outer heat preservation system greatly, during as the Highrise buildings facing, can the brick phenomenon not occur falling because of bearing the blast problem, thereby guarantee the external thermal insulation system safety and reliability.Facing mortar is decorated at the inner, external wall that developed country extensively replaces coating and ceramic tile to be applied to build.But also there are some unsatisfactory places in facing mortar in applying, and distinct issues are easy accumulation of salt in the surface soil, thereby have a strong impact on the outward appearance of body of wall.The accumulation of salt in the surface soil is the insoluble problems of all cement base products, and reason roughly has two: the first, and the main component of Portland cement is Calucium Silicate powder (CasiO
3), in meeting the water process, C
3S, C
2When the S aquation generates the C-S-H gel, can generate a large amount of Ca (OH)
2, because Ca (OH)
2Can be dissolved in water and form Free Ca
2+, under a large amount of situations about existing of water, water just becomes flowing carrier, is carrying a large amount of Ca
2+ be penetrated into the mortar surface by the pore of decoration mortar self, arrive the Ca on surface
2+ with airborne CO
2Reaction generates CaCO
3And be deposited on the surface and form the accumulation of salt in the surface soil; The second, the basic oxide too high levels in some silicate cement after corresponding cement-based mortar product adds water and mixes and stirs, can form a large amount of free Na+, K+, the CaSO in Na+, K+ meeting and the cement
4Reaction forms NaSO
4, K
2SO
4Deng water-soluble salt, these water-soluble salts can be with water carrier migration to material surface, and separate out bloom shape material along with water evaporation.This shows that the accumulation of salt in the surface soil takes place needs 4 conditions: 1. have water-soluble salt, 2. water exists, 3. salts solution migration, the 4. volatilization of moisture.By the accumulation of salt in the surface soil phenomenon that second reason causes, through the flushing of rainwater, the degree of the accumulation of salt in the surface soil can alleviate gradually, and the accumulation of salt in the surface soil phenomenon that causes by first reason, then can be with the growth of the time of exposing to the sun and rain, the degree of the accumulation of salt in the surface soil can be more and more serious.
Summary of the invention
For overcoming above-mentioned accumulation of salt in the surface soil problem, the invention provides a kind of anti-crystalline bloom exterior wall facing mortar, comprise following component and weight proportion: 10-20% silicate cement, 2-3% high-alumina cement, 1-2% model plaster, 50-80% quartz sand, 2-4% additive.
For preventing coating cracking, also for avoiding the reaction of self-contained a small amount of CaO of high-alumina cement and water to generate Ca (OH) 2, above-mentioned additive comprises wood fibre, hydrophobic type rubber powder and nano level hydrophobizing agent.
In the above-mentioned additive, the weight percent of hydrophobic type rubber powder, wood fibre and nano level hydrophobizing agent is hydrophobic type rubber powder 70-80, wood fibre 6-10, nano level hydrophobizing agent 2-5.
Above-mentioned hydrophobic type rubber powder, its base polymer are the acrylate rubber powder
Above-mentioned nano level hydrophobizing agent is a modified alta-mud, derives from the natural inorganic thing, and its hydrophobic function is not in time with the change of surrounding environment and change.
The preferred alumina content of above-mentioned high-alumina cement is the aluminate cement of 35%-45%.
The preferred alpha-semi water plaster stone of above-mentioned gypsum
The present invention does not require the fineness of sand, and though the sand of which kind of order number, even can all not have accumulation of salt in the surface soil phenomenon small to injection, but for easy construction, the preferred order number of above-mentioned sand is a 20-50 purpose quartz sand.
In order to satisfy construction requirement and to guarantee the mortar early strength, above-mentioned additive also comprises retardant and water-holding agent, and the addition of retardant is the 0.05%-0.3% of facing mortar gross weight, and the addition of water-holding agent is the 0.05%-0.3% of facing mortar gross weight.
In order to make the facing mortar layer present distinct colors, above-mentioned additive also comprises pigment, and the addition of pigment is the 0.9%-1.5% of facing mortar gross weight.
Beneficial effect of the present invention is: polyalcohol cement basis body of wall colored finish mortar of the present invention, and the inorganic gel material adopts high-alumina cement, substitutes ordinary Portland cement, and the effect of two aspects is arranged:
The first, high-alumina cement does not produce Ca (OH) when aquation
2, can reduce the risk that the accumulation of salt in the surface soil produces so greatly, its reaction formula is as follows:
6(CaO.AL
2O
3)+6(CaSO
4.1/2H.O)+73?H
2O＝2(3CaO.Al
2O
3?3CaSO
4.32H
2O)+8Al(OH)
3
6(CaO.2AL
2O
3)+6(CaSO
4.1/2H.O)+91?H
2O＝2(3CaO.Al
2O
3?3CaSO
4.32H
2O)+20Al(OH)
3
The second, high-alumina cement is when aquation, and CaO concentration is low in its liquid phase, AC
2O
3Concentration is higher, aluminium mineral material can be finished aquation by dissolving, diffusion and crystallization process more comfortably, in addition, degree of supersaturation during the ettringite crystallization is less, and the ettringite column crystallization that aquation generates just can be present in whole water-filling space more dispersedly, and ettringite distributes comparatively even, another product---aluminium glue has the filling densification and aquation generates, therefore the facing mortar that is formed by high-alumina cement, porosity is low, the aperture is little, significantly reduces the approach that salts solution moves.Based on this 2 point, the condition that the accumulation of salt in the surface soil produces just can be suppressed well, even through exposing to the sun and rain for a long time, also is not prone to the accumulation of salt in the surface soil.
In addition, because high-alumina cement has the CaO of small-amount free to produce in process of production unavoidably, and these free CaO still can cause the accumulation of salt in the surface soil by a spot of pore migration to the mortar surface, when the present invention adopts wood fibre as additive, also add hydrophobic type rubber powder and nano level hydrophobizing agent, by the good hydrophobic nature of rubber powder, after capillary hole wall film forming, significantly reduce the contact area of water and material surface, make the globule on the finish coat be difficult for infiltrating the inner and CaO reaction of hole, form Ca (OH) by pore
2Saturated solution glows from pore and takes away free Ca
2+, form the accumulation of salt in the surface soil.
Polyalcohol cement basis body of wall colored finish mortar of the present invention, every technical indicator all meets JC/T1024-2007 metope facing mortar standard-required, by anti-accumulation of salt in the surface soil test, the no accumulation of salt in the surface soil phenomenon in 21 damp and hot circulation backs (pressing standard-required) produces, the open air is made sample and is observed, go through the some months wind and rain, the no accumulation of salt in the surface soil.Facing mortar of the present invention adds different pigment, and the colour-change scope is wide, and moulding is abundant, is particularly suitable for the decoration of high-end residential or villa exterior wall.
