Abstract
The present invention discloses a novel powdery air-permeable waterproof material which is a powdery material mainly prepared from the following components: 35 to 45% of cement, 25.5 to 52.7% of quartz sand, 5 to 10% of swelling agent, 0.5 to 1% of organic silicon, 1 to 3% of calcium formate, 1 to 4% of bentonitic clay, 0.3 to 0.5% of hydroxypropyl methyl cellulose, 2 to 4% of redispersion powder, 2 to 6% of silicon powder and 0.5 to 1% of polypropylene monofilament fiber. The present invention has the advantages of good waterproof performance, rigid and flexible combination, stability, reliability, firm base layer bonding, high surface strength, excellent air permeability, good construction performance, no overlapped seam, no dehiscence and long service life, and is suitable for the water prevention of various buildings.
Description
Technical field
The present invention relates to a kind of water-proof material, specifically a kind of new powdered air permeable waterproof material.
Background technology
Building Trade in China development in recent years is very fast, finishes floor area of building every year and reaches 2,000,000,000 square metres, and only the area, Shanghai every year will be nearly 2,000 ten thousand square metres, and it is many year by year to be used for the input of waterproof construction aspect.The ratio of waterproofing work cost reaches more than 15% in project total cost at present, and particularly vault has reached construction costs 25%-30%, although have high input, waterproof effect is unsatisfactory.According to incompletely statistics, percolation ratio is about about 10% then for new construction, and the maintenance cost that country is used for the buildings waterproof aspect every year reaches about 2,000,000,000 yuan.Although in these years China development aspect of being used for building roofing, vault, toilet warterproof material has obtained very much progress, successively develop many product innovations, but because many aspects, the infiltration of some buildingss, drainage are still very general.Mainly there is the seam lap problem in the waterproof roll of usefulness in the market, and especially the special-shaped part difficulty of construction is big, simultaneously the problem that also exists hollowing to flake with the basic unit bonding, thereby the seepage of causing, simultaneously substrate humidity is required also high (water ratio＜10%), otherwise also easily flake, cause the waterproof failure; And waterproof paint Polyurethane for example requires basic unit to want dry too, and the wet basis layer can not be constructed, otherwise easily foaming, hollowing and cause the waterproof failure.Be used for vault in addition because waterproof membrane intensity is low, thus basement waterproofing film construction finish (when enclosing soil, also need special build a pipe protection wall in case fill out earth when enclosing soil, stone is made a mess of waterproof membrane and cause the waterproof failure.The waterproof material of therefore constantly researching and developing out the water resistance excellence is the task of top priority.
Summary of the invention
Good, the moderate new powdered air permeable waterproof material of a kind of easy construction, water resistance that provides at the deficiencies in the prior art is provided, and can makes its industrialization.
The concrete technical scheme that realizes the object of the invention is:
A kind of new powdered air permeable waterproof material, it mainly is the powder material of being made by following routine component: (weight percentage)
Cement 35-45%
Quartz sand 25.5-52.7%
Swelling agent 5-10%
Organosilicon 0.5-1%
Calcium formiate 1-3%
Wilkinite 1-4%
HPMC 0.3-0.5%
Redispersion powders 2-4%
Silica flour 2-6%
Polypropylene monofilament fiber 0.5-1%
Described swelling agent is a cement expansive material.
Described redispersion powders is the terpolymer redispersion powders.
Water resistance of the present invention is good, and hard and soft combination is reliable and stable, and basic unit's bonding is firm, the surface strength height, and the permeability excellence, application property is good, and no seam lap is not ftractureed, and the life-span is long, is applicable to the waterproof of various buildingss.
Embodiment
The present invention is that gelling material and quartz sand are formed a basic bonding aggregate with cement, it is the main matrix of water-proof material, polypropylene monofilament (Durafiber) fiber mainly is the tensile strength that improves water-proof material, and the plastic shrinkage that absorbs and disperse in hydration process, to produce owing to cement, the stress that drying shrinkage and temperature difference contraction problem form, thereby can prevent fissured generation effectively, play the cracking resistance effect, and redispersion powders can be dispersed in the water-proof material admirably, these polymer powders can have the flexible macromolecule resin with cement and surface of aggregate parcel one deck in adding water stirring and hydration process, and formed external phase, thereby the fragility of water-proof material is greatly improved, makes it become hard and soft bonded composite water-proof material.
Construct on wet base in order to make this water-proof material, therefore it must have air permeability and good, only in this way, moisture content in the moist concrete basic unit is gone by surperficial being diffused in the air of the water-proof material with respiratory function, and unlikely causing owing to the moisture content in the wet base of this water-proof material construction back can't be overflowed and caused the hollowing of waterproof layer to flake, make the waterproof layer failure, in order to reach this effect, added silica flour among the present invention, thereby reach extraordinary ventilation property, because this material is coated on the surface of hardenite inner pore wall equably, produce bigger surface tension, therefore, the present invention has good waterproof and hydrophobic nature, and ventilation property.In order to improve its application property, particularly under summer high temperature, construct, for the moisture content of the water-proof material that makes thin layer is difficult for overflowing, make its hydration reaction fully, we have selected for use and have had water retaining function quite water-holding agent, the Vltra tears of excellence for this reason.
