Description
Technical field
The invention belongs to building material technical field, the decoration mortar of more particularly to a kind of water-proof alkali-resistant and its preparation side
Method.
Background technology
Decoration mortar is that a certain amount of inorganic ore deposit of addition is often needed in a kind of mortar as building facing, practical application
Thing pigment is mixed colours.The decoration mortar after toning is createed into colourful decoration with various construction tools again afterwards to imitate
Really.At present, decoration mortar is widely used in skin, and external plinth course can play a very good protection and decorate effect
Really.
But traditional decoration mortar is the inorganic material based on cement base mostly, therefore it is intrinsic to there is many cement-based materials
Shortcoming, such as low intensity, the easy accumulation of salt in the surface soil, poor flexibility, big water absorption rate the problems such as.To solve problem above, traditional way is in water
Auxiliary material, such as latex powder, silane hydrophober organic material are added on the basis of mud base material.Though this method can improve within the specific limits
The performance of decoration mortar, but can not tackle the problem at its root, and organic material weather resistance is poor, can bring serious matter
Amount problem.
Generally speaking, the problem of key factor of influence traditional decoration mortar quality is mainly the accumulation of salt in the surface soil and high water absorbing capacity.Its
In, the accumulation of salt in the surface soil is the common fault of all cement-based materials, and key, which is that in hydrolysis product of cement, contains substantial amounts of calcium hydroxide, these
Calcium hydroxide moves to architectural surface along duct under vapour pressure or generates white carbon with the carbon dioxide reaction in air
Sour calcium powder leaves white point or direct evaporative crystallization formation hickie and then had a strong impact on attractive in appearance.Traditional decoration mortar water absorption rate height,
Compactness is poor, and when being attacked by rainwater, a large amount of water penetrate into inside along decoration mortar, so as to reduce decoration mortar to concrete
The protection of basic unit, while decoration mortar durability can also be reduced.It can be seen that, the build-in attribute of cement base decoration mortar is seriously made
The about development of decoration mortar.
The content of the invention
It is an object of the invention to provide a kind of decoration mortar of water-proof alkali-resistant and preparation method thereof, to solve traditional decoration sand
The problems such as existing water absorption rate height of slurry, accumulation of salt in the surface soil.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
A kind of decoration mortar of water-proof alkali-resistant, the decoration mortar is made according to mass percent meter by following raw materials according：
Metakaolin：20%~30%；Flyash：2%~3%；Silicon ash：3%~5%；Quartz sand：40%~55%；
Waterglass：5%~15%；Caustic soda：3%~7%；Water：6%~15%；Inorganic mineral pigments：0.2%~1.2%；PP is fine
Dimension：0.1%~0.3%.
The metakaolin main component is active silica and aluminum oxide, and calcium oxide mass content is not higher than
0.05%.It is preferred that the metakaolin of the chemical composition of table 1 composition：
The metakaolin chemical composition % of table 1
| Al2O3 | SiO2 | CaO | Fe2O3 | K2O | MgO | Na2O | Other | Loss on ignition |
| 45.45 | 51.9 | 0.05 | 0.25 | 0.26 | 0.03 | 0.04 | 2.02 | 1.05 |
The superfine powder of the mesh of metakaolin preferred white 1250, its calcium content is extremely low.
Metakaolin is the bonding component in decoration mortar.
The volume of described flyash is the 8-12% of metakaolin quality.It is preferred that more than II grade ash, when mixing for flyash
Measure for the 10% of metakaolin quality when, the alkali resistant ability of decoration mortar is optimal.
The Silica fume content is the 10-15% of metakaolin quality, and more preferably volume is the 12% of metakaolin quality, can
Effectively improve decoration mortar intensity and alkali resistance；In addition, silicon ash is preferred to use white 800 mesh silicon powder.
The quartz sand uses 20-40 mesh, 40-70 mesh, the quartz sand in mass ratio 9 of 325 three kinds of specifications of mesh:3:1 mixing
Obtain.This level is matched somebody with somebody and ratio can reach closestpacking state, can effectively improve decoration mortar compactness, reduces water absorption rate.
Waterglass is with analyzing pure caustic soda compounding as alkali-activator, and described modulus of water glass is 2.0-2.5, waterglass
Prepared with caustic soda by different proportion, be 2 preferably according to mass ratio:1.The stimulation effect of compound exciting agent is optimal, increases
The glass content that adds water can reduce intensity, and increase causticity sodium content can accelerate setting rate.
The composition of inorganic mineral pigments and specific volume need to only be determined according to the scheme of colour of decoration mortar.
The length of pp fibers is 3mm, and addition is not more than 3L according to PP fiber volumes in every cubic metre of decoration mortar to be carried out
Addition.Its main function is to increase the cracking resistance of decoration mortar, therefore preferably uses short and thin specification, should not be added
It is many, it otherwise can significantly reduce the mobility of decoration mortar.
The invention provides a kind of inorganic polymer gel material of novel anhydrous mud (hereinafter referred to as geopolymer) conduct
The binding agent of decoration mortar, both can inherently reduce accumulation of salt in the surface soil risk, and compactness and intensity can be improved again, reduce water absorption rate.
Decoration mortar of the present invention is metakaolin based inorganic polymer mortar, and binder materials is extremely low using calcium content
Active metakaolin, alkali-activator is matched somebody with somebody from modulus for the waterglass between 2.0-2.5 to be combined made from proper amount of caustic soda
Type exciting agent, and add the alkali resistant cracking resistance and water resistance of the increase decoration mortar such as a certain amount of flyash, silicon ash, PP fibers.
It is, in principle, that metakaolin base decoration mortar of the present invention, by sial active mineral (metakaolin, flyash, silicon ash)
Each component calcium content pole in the inorganic polymer of space net structure, decoration mortar is aggregated into after alkali-activator is excited
Low, the product of polymerisation is mainly amorphous polymer and water, and in the absence of conventional cement sill hydrated product hydrogen-oxygen
Change calcium, its polymerizate compact structure, compactness is very high, good water-proof effect.This has just inherently prevented cement well
The problem of base decoration mortar accumulation of salt in the surface soil and too high water absorption rate, and it is distinctive resistance in the absence of the cement base decoration mortar of addition organic material
Sex chromosome mosaicism is waited, therefore its application value is very high.
The present invention still further provides a kind of preparation method of water-proof alkali-resistant decoration mortar, first mix caustic soda with water
Close, add afterwards after waterglass and be well mixed acquisition exciting agent；Then by the quartz sand mixed and metakaolin, flyash,
Silicon ash, inorganic mineral pigments are sufficiently mixed acquisition powder；Exciting agent is added portionwise, makes it fully anti-with powder after adding every time
Should；PP fibers are eventually adding to be sufficiently mixed uniformly.
Exciting agent is preferably added in three times.
The present invention compared with prior art, has the following advantages that：
A kind of decoration mortar of water-proof alkali-resistant of the present invention is to use alkali-activator direct stimulating activity powder (slag, powder
Coal ash, metakaolin, silicon ash etc.) a kind of active inorganic polymer prepared, therefore it has excellent physical and mechanical property (as early
Strong fast hard, compactness is high, water absorption rate is low, accumulation of salt in the surface soil risk is low, compact structure intensity high, water resistance is good, weather resistance is excellent
Deng), it is a kind of extraordinary ordinary cement alternative materials, can be completely without any cement in its preparation process, thus have
There is high environmental value, gather around and have broad application prospects in building material field.
