Description
Technical field
The invention belongs to building material field, be specifically related to a kind of stealthy water-resisting agent and preparation technology thereof.
Background technology
Steel Concrete is human at present the most large building structural materials that uses.The major cause of concrete deterioration process (physics, chemistry and biological) and reinforcing bar or deformed bar generation deterioration has freeze-thaw cycle, alkali-aggregate reaction, sulphate attack, shrinkage cracking and steel bar corrosion etc.
As far as above-mentioned any deterioration process, it is all relevant with water with the rimose reason to expand, and water also is that corrosive medium (like villaumite, vitriol etc.) migration gets into the carrier in the concrete simultaneously.Water is the transmission medium that destroys material, is again to destroy the prerequisite of generation and the basis of many failure mechanisms and modelling.The comprehensive various degradation mechanism of concrete structure can know that nearly all chemistry and physical process that influences concrete structure durability all relates to two main influence factors, i.e. water and the migration in concrete pore and crack thereof.
Concrete is a kind of composite porous.In sclerosis coagulation scholar, often there is the different lonely L in aperture, like gel pore, pore, microscopic checks etc.When these holes formed the path of successive and mutual linking, moisture very easily infiltrated.The compound migration of the water between concrete and environment, heat and chemical substance and the parameter of controlling these migration mechanisms constitute the principal element influence concrete durability.The existence of water or moisture is an independent and important factor of the various types of deterioration processes of control.Study waterproof material, prevent that moisture is significant to the weather resistance that improves concrete structure to inside concrete infiltration technology and method.
Therefore, how improving the concrete structural surface water resistance is the aspect that the novel water-proof material emphasis of research and development is considered.Cementitious capillary waterproofing material is to use one of concrete structural surface water-proof material very widely at present.Yet along with concrete technology constantly develops to high-strength, high-performance direction, concrete structural strength is increasingly high, and the result of use of traditional cement base osmotic crystalline waterproof material also more and more a little less than.Simultaneously; Because the traditional cement base osmotic crystalline waterproof material need mix and stir in cement and mortar and use; Therefore in application process, can only be applied in the material of construction such as plastering mortar, decoration mortar, for then carrying out post-processed easily in the concrete-containing building material structure of having built up.At present, a lot of early stage buildings were not owing to carried out WATER REPELLENT to its building materials when initially building, therefore in follow-up use in case phenomenon such as occur leaking uses existing cement-base infiltration crystallization property water-proof material conveniently to solve.The water-resisting agent majority of some other kind of the prior art is to adopt the cover type waterproof; In case throw off with basic unit and very easily to produce the seepage phenomenon; And for dissimilar; The outside of especially erose building structure or interior construction adopt the cover type good waterproof effect often not fully up to expectations.
To sum up; From the development trend of concrete technology development, concrete structure leakage cause, construction material and the case study of water-proof material existence, developing a kind of stealthy water-resisting agent that has hypertonicity and adopt spraying method to construct has become those skilled in the art institute problem demanding prompt solution.
Summary of the invention
The object of the present invention is to provide a kind of stealthy water-resisting agent and preparation technology thereof.Stealthy water-resisting agent among the present invention is a kind of waterproof that is used for concrete structure and moistureproof with adding water-resisting agent.Stealthy water-resisting agent of the present invention can be used for waterproofing works such as all kinds of concrete structures, building inside and outside wall, vault, tunnel, people's air defense, and the protection against the tide of porous masonry structure and various ornament layers, waterproof are a kind of stealthy efficiently water-resisting agents.
To achieve these goals, the present invention adopts following technical scheme:
A kind of stealthy water-resisting agent is made up of tartrate, Sodium Fluoride, silicon sol, silane emulsion and water, and the weight percent of each component is:
Tartrate 15%～28%;
Sodium Fluoride 8%～19%;
Silicon sol 2%～10%;
The solid content 1%～10% of silane emulsion;
Folium Nelumbinis essenc 1%～10%;
Water 33%～74%.
The preferred version of composition is: tartrate 20%; Sodium Fluoride 15%; Silicon sol 6%; The solid content 6% of silane emulsion; Folium Nelumbinis essenc 5%; Water 48%.
The preparation method of stealthy water-resisting agent of the present invention comprises the steps:
Press each component of formula rate weighing; Successively tartrate, Sodium Fluoride, silicon sol, silane emulsion, Folium Nelumbinis essenc are successively added then and make mixing solutions in the entry; In reaction kettle, mixing solutions is stirred; Handle the impurity of removing in the solution through filtering then, the clear liquid after the filtration treatment promptly makes stealthy water-resisting agent of the present invention.
Preferably, said filtration treatment is selected from: can be the acidproof strainer filterings of 400 purposes through the number of looking over so as to check with mixing solutions, isolate the solid impurity that possibly exist and get final product.
The method of use of stealthy water-resisting agent of the present invention is: at first the concrete surface of using is carried out pre-treatment; Said pretreated concrete steps are: greasy dirt or other foreign material of removing the concrete surface surface; The surface keeps dry; Adopt the form of construction work of brushing or spraying that stealthy water-resisting agent is applied to concrete surface then, can spray one time, but also after the first pass drying; Spray second time, can further strengthen waterproof effect.
The present invention is directed to present concrete technology development trend and concrete structure leakage cause and waterproof demand, the stealthy water-resisting agent of a kind of efficient penetrant crystalline, waterproof, enhancing, function such as hydrophobic is provided.Stealthy water-resisting agent of the present invention is a kind of Waterproof admixture of being made up of the various active chemical composition.After it was sprayed on the concrete structural surface, it had very strong penetrating power and stronger hydrophobic performance.Active compound reacts in pore with hydrated product in the concrete to inside concrete infiltration and diffusion, produces needle-like or fibrous xln, blocks capillary channel, thereby makes concrete compaction, increases ultimate compression strength, plays not only waterproof but also gas-pervious function.
In the stealthy water-resisting agent of the present invention; Tartrate, Sodium Fluoride, silicon sol etc. can efficiently infiltrate concrete base layer; And generate crystalline product with hydrated cementitious product reaction, can closely knit waterproof action, and silane emulsion can further play the hydrophobic waterproof action to the concrete base laminar surface.
