Description

A kind of wear-resisting waterproofing and leakage-stopping mortar and preparation method thereof
Technical field
The present invention relates to building material technical field, particularly relate to a kind of wear-resisting waterproofing and leakage-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.
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 wear-resisting waterproofing and leakage-stopping mortar and making thereof Method.
The present invention is achieved by the following technical solutions:
A kind of wear-resisting waterproofing and leakage-stopping mortar, is prepared by the raw materials in: Portland cement 24-26, river sand 49- 51, medical stone powder 13-14, white carbon black 17-19, banana fiber 2-3, polypropylene fibre 3.6-4.5, styrene-acrylic emulsion 8-10, calcium sulfate 0.4-0.6, nano silica fume 2.1-2.4, IPPP 3-4, vinyltrimethoxy silane 7-9, suitable quantity of water.
The manufacture method of described a kind of wear-resisting waterproofing and leakage-stopping mortar, comprises the following steps:
(1) under nitrogen protection by vinyltrimethoxy silane heated and boiled, add nano silica fume and keep temperature stirring 1-2 little Time, filtering, wash after drying, addition banana fiber, white carbon black grind 30-40 minute, freezing 3-5 hour at subzero 15-20 DEG C, Prepare organic modified nano silica flour；
(2) medical stone powder is put in 60-80 DEG C of ultrasonic disperse 1-2 hour in concentrated hydrochloric acid, washing to neutral, 30-50 DEG C of vacuum It is dried, adds IPPP ultrasonic disperse and within 2-3 hour, obtain modified medical stone powder；
(3) styrene-acrylic emulsion being heated to 80-90 DEG C, addition polypropylene fibre, organic modified nano silica flour are put in high mixer high Speed stirring 1-2 hour, is cooled to room temperature, adds Portland cement, modified medical stone powder and other residual componentss and grinds 1-2 Hour, discharging, wherein the ratio of mud is 1: 0.4.
The invention have the advantage that the present invention adds nano silica fume and carried out organically-modified, reduce surface and can make it Have facially amphiphilic, thus utilize three-dimensional protective effect to make nanoparticle be homogeneously dispersed in mortar and be difficult to reunite, carry The comprcssive strength of high product and anti-wear performance, more compound with polymer styrene-acrylic emulsion and polypropylene fibre, pass through physics And chemical action, improve polypropylene fibre surface can so that the cohesive force between itself and mortar improves further, it is suppressed that in early days The generation of micro-crack, improves the impermeability of product, rupture strength and durability；The present invention is also by modified for medical stone powder interpolation Other effective additives of compatibility again in raw material so that each component of mortar is uniformly dispersed not free settling, hence it is evident that improve leak stopping sand The water resistance of slurry also shortens its rapid hardening speed, preparation technology of the present invention is simple, easy construction, have after curing molding micro-swollen The performances such as swollen performance is good, self-healing properties is good, wear-resisting.
