Description
Technical field
The present invention relates to building material technical field, particularly relate to a kind of anti-cracking waterproof leak stopping mortar and preparation method thereof.
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 be 0.6kg/m3, styrene-acrylic emulsion volume be 10% time, 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.
