Description
Technical field
The present invention relates to decoration mortar field, particularly to a kind of preparation method of alkali-activated carbonatite flyash decoration mortar.
Background technology
Due to the requirement of building energy conservation, wall heat insulation material quickly grows in recent years, has obtained large-scale use, to dress
The cracking resistance of decorations mortar, impervious and tensile bond strength are put forward higher requirement.In order to comply with the development trend of building energy conservation with
And meet high-rise and high-rise building security use requirement, safe, decorative effect enrich and excellent performance decoration
Mortar will be increasingly becoming the main flow of external wall decorative material.Want to meet long-term serviceability requirement, decoration mortar must have
Good substrate adhesion, low water absorbable and good mechanical property, generally, its elastic modelling quantity will be less than base material.Plus
Enter polymer to be lifted the cementitiousness of decoration mortar, flexural capacity further and reduce its water absorption rate etc., in repeated deformation
In the case of be not in fatigue rupture, produce crack, there is good crack resistance.At present at home, the application of decoration mortar is simultaneously
Not extensively, the aberration mainly due to cement base polychromy mortar and the technology of the initial stage accumulation of salt in the surface soil do not obtain effectively solving.
The accumulation of salt in the surface soil is otherwise known as and analyses white or scum, and main performance is that material surface one layer of white material, typically reality
Often visible in life, just can be removed by washing, pickling or naturally drop, but in actual fitment process, serious shadow
Ring the outward appearance of building, or even the quality that construction material can be affected.There are some researches show：The main cause of the decoration mortar accumulation of salt in the surface soil is that exist
, there is the excessive moisture as accumulation of salt in the surface soil carrier in the alkaline matter producing as the mortar raw material aquation of accumulation of salt in the surface soil composition；There is the accumulation of salt in the surface soil
The body hole of passage；The low temperature and high relative humidity of external environment.The reason impact aberration, has a lot, and the batch of such as raw material is stable
Property, metering accuracy and the factor such as water consumption, construction environment.
Chinese Patent Application No. is 201210547848.7, and the patent document of Publication No. CN 103102120 A discloses
A kind of decoration mortar and preparation method thereof, it consists of the following parts by weight：300～500 parts of white cements, 300～500 parts of quartz
Sand, 30～50 parts of latex powder, 3～6 parts of water-loss reducers, 80～150 parts of dry powders, 1～3 part of thixotropic agent, 1～4 part of water reducer, 0.5
～2 parts of polypropylene fibres, 3～6 parts of wood fibres, 5～15 parts of polyvinyl alcohol；Dry powder addition mixer is stirred, so
Add the pre-composition of other components afterwards, stir and obtain final product decoration mortar；Suitable quantity of water only need to be added during use to mix.
The inventive method is simple, and the external decorative mortar of preparation has good high and low temperature resistance and a resistance to ag(e)ing, high mechanical properties,
Good with the cohesive force of substrate, the good feature of crack resistence effect, and environmental protection, with low cost.This decoration mortar cement consumption is inclined
Height, causes the later stage easily to produce the accumulation of salt in the surface soil and shrinkage cracking problem, the polyvinyl alcohol solubility containing in formula system is poor, and inhales
Aqueous strong and rate of perviousness is big, and water absorption rate, up to 30%～50%, makes air-tightness and mechanical strength decline, and is easily subject to alcohol after water suction
Class, the erosion of lipid equal solvent, thus affect the decoration quality of decoration mortar.
Chinese Patent Application No. is 201410459387.7, and the patent document of Publication No. CN 104230277 A discloses
A kind of decorating inner and external walls low alkalinity polychromy mortar, this decoration mortar is one-component dry powder, by following percentage by weight
