Description
Technical field
The present invention relates to building material technical field, particularly relate to a kind of rapid-hardening waterproofing and leakage-stopping mortar and making side thereof
Method.
Background technology
Leakage of buildings problem is the common quality defect that building more highlights, and tracing it to its cause is architectural engineering xoncrete structure
Because the reasons such as autogenous shrinkage, temperature deformation, design defect or construction produce crack, cause seepage, thus cause roof leakage, wall
Wall seepage, rendering layer obscission, not only upset orthobiosis and the work of people, and directly influence whole solitary building
In service life, waterproofing and leakage-stopping mortar arises at the historic moment.Waterproofing and leakage-stopping mortar, with high grade cement, sand, stone as raw material, mixes multiple high score
Sub-additive, by adjusting match ratio, is improved cement pore structure, increases various raw-material density, or shunk by compensation
Improve the anti-crack and anti-seepage ability of concrete.
Waterproofing and leakage-stopping mortar is widely used in China, and manufacturing enterprise is numerous, from the point of view of base material essence, mainly with aluminate
Cement based or portland cement sill are base material.Aluminate cement later strength in wet condition can reduce, and silicate
There is length setting time, early strength development and slowly and produce the fundamental issues such as contraction after hardening in cement, thus increasing is added in research
The new waterproof leak stopping mortar of strong material is significant.
Polypropylene fibre has the advantage such as easy construction, with low cost, resistance to chemical attack, mixes as reinforcing material
In cement mortar, it is possible to reduce mortar is the generation of micro-crack in hardening process, and stop or delay it to extend, thus effectively carrying
The tensile strength of high mortar.But polypropylene fibre smooth surface, surface can without any active group on low, strand, and
Surface hydrophobicity, causes it poor with cement matrix adhesive property.Exist simultaneously as PP fiber reinforced cement mortar is internal
A large amount of holes, cause cement-hydrate, polypropylene fibre and aggregate interracial contact abundant not, reduce the durable of cement mortar
Performance, these all have influence on polypropylene fibre application effect in cement-based material, constrain its range of application.To this end, it is " poly-
The tacryl impact on polymer cement mortar performance " use a certain amount of styrene-acrylic emulsion of admixture to PP fiber reinforced cement sand
Slurry is modified, and result shows: admixture polypropylene fibre and styrene-acrylic emulsion are remarkably improved the rupture strength of cement mortar simultaneously
And anti-permeability performance, when polypropylene fiber is 0.6kg/m3, styrene-acrylic emulsion volume is when being 10%, compared with benchmark mortar specimen,
Its 28d rupture strength and impermeability pressure increase 29.20% and 400% respectively.But, use the water that the processing method in literary composition obtains
The comprcssive strength of cement mortar is low, also needs to be modified.
Nano material possesses skin effect, small-size effect, quantum size effect, macroparticle tunnel-effect, and these are special
Different character makes it in polymer modification, improves in coating, binder performance and becomes irreplaceable material, and the present invention uses nanometer
Material adds in raw material to styrene-acrylic emulsion is the most modified, with improve product comprcssive strength, water-fast impervious, anticorrosion is resistance to always
The performances such as change, but these special natures of nano material there is also certain limitation, such as due to small size can be big than table
Easily reunite, cause disperseing uneven, thus be necessary to be then added in raw material, to change the nano material added is in addition modified
The all technical of kind product.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of rapid-hardening waterproofing and leakage-stopping mortar and system thereof
Make method.
The present invention is achieved by the following technical solutions:
A kind of rapid-hardening waterproofing and leakage-stopping mortar, is prepared by the raw materials in: Portland cement 23-25, quartz sand
50-52, flyash 18-20, polypropylene fibre 3-5, acrylic fiber 2-4, styrene-acrylic emulsion 6-8, polymethyl methacrylate 5-
7, butyl titanate 14-16, dimethylaniline 3.5-3.8, sodium hexameta phosphate 0.4-0.7, calcium nitrate 0.3-0.5, nano oxidized
Zinc 1.4-1.7, suitable quantity of water.
The manufacture method of described a kind of rapid-hardening waterproofing and leakage-stopping mortar, comprises the following steps:
(1) under nitrogen protection by butyl titanate heated and boiled, add nano zine oxide and keep temperature to stir 1-2 hour, mistake
Filter, washing are dried, at subzero 15-20 DEG C freezing 3-5 hour, add sodium hexameta phosphate and pulverize prepared organically-modified receive
Rice zinc oxide；
(2) being put into by flyash in 60-80 DEG C of ultrasonic disperse 1-2 hour in concentrated hydrochloric acid, washing is to neutral, and 30-50 DEG C of vacuum is done
Dry, add dimethylaniline ultrasonic disperse and within 2-3 hour, obtain aminated modified coal ash, add the poly-methyl-prop of molten condition
E pioic acid methyl ester, keeps temperature ultrasonic disperse 30-50 minute, and modified coal ash is ground to obtain in cooling；
(3) styrene-acrylic emulsion being heated to 80-90 DEG C, addition polypropylene fibre, acrylic fiber, organic modified nano zinc oxide are put
Enter high mixer high speed to stir 1-2 hour, be cooled to room temperature, add Portland cement, quartz sand, modified coal ash and
He grinds 1-2 hour at residual components, and discharging, wherein the ratio of mud is 1: 0.4.
The invention have the advantage that the present invention adds nano zine oxide and carried out organically-modified, reducing surface can make
It has facially amphiphilic, thus utilizes three-dimensional protective effect to make nano zinc oxide particles be homogeneously dispersed in mortar and be difficult to
Reunite, improve the comprcssive strength of product, more compound with polymer styrene-acrylic emulsion and polypropylene fibre, by physics and change
Effect, improve polypropylene fibre surface can so that the cohesive force between itself and mortar improves further, inhibits well early
The generation of phase micro-crack, thus improve the impermeability of product, rupture strength and durability；The present invention is also by after flyash modified
Add in raw material other effective additives of compatibility again to so that each component of mortar is uniformly dispersed not free settling, hence it is evident that improve stifled
Leaking the water resistance of mortar and shorten its rapid hardening speed, prepared waterproofing and leakage-stopping mortar has height water-fast, impervious, crack resistance
By force, characteristic that caking property is high, from solving leakage problems at all.
