Description
Technical field
The present invention relates to a kind of engineering plugging, waterproof cement based material for quickly stopping leakage.Specifically, relate to a kind of fast blockage, the water-proof material that a kind of waterproofing work that is used for fields such as construction work, water conservancy project, maritime works, bridge, tunnel, petroleum engineering is used.
Background technology
In construction work, hydro project, public works, often inconsiderate because of structure design, select for use water-proof material improper. construction quality is poor, uneven settlement of foundation etc. caused the seepage of construction of structures.Particularly under the situation about rolling up for present high-rise, also corresponding increases such as vault, elevator raise, pond, roof.These structures are bad as handling, and will produce seepage, influence the normal use and the life-span of structures, must carry out leakage blocking and seepage-proofing and handle.
Patching materials on the domestic market is mainly following several big class at present, and a class is cement-inorganic coagulant class, and this class material is base-material with the Portland cement. mix a certain proportion of fast component of coagulating.Owing to it solidifies soon, annotate toward mixing and stirring inhomogeneous promptly gathering together and use, and the cement contraction is big, periphery usually seeps water.Lack cohesive force with the old substrate of concrete, often fall down a monoblock once pulling, cause the leak stopping failure at last with hand.And water glass has stronger corrosive nature, easy skin ambustion to skin.Bring difficulty to operation.Second class is cement-organic setting accelerator class.This class material is a base-material with the Portland cement, mixes patching materialss such as a certain proportion of organic solution, fatty acid metal salt, synthetic resin emulsion and water soluble resin, and the advantage of this class material is that time of coagulation is fast.But cost an arm and a leg.The performance less stable, poor durability, not acid-alkali-corrosive-resisting.The 3rd class is synthetic patching materials class, and this class material is to be base-material with the Portland cement, adds the commercialization patching materials that extraordinary inorganic water-proof masterbatch etc. mixes.But this class condensation of materials time is often slow partially.For water burst and the bad processing of seepage that sprays into.Only being applicable to that big area humidity, submerged wipe one's face to mend oozes.The 4th class is to be the material for quickly stopping leakage of major ingredient with fluoaluminate and sulplo-aluminate.This material can solidify in several minutes, and can produce higher hour intensity.And other organic material for quickly stopping leakage etc.
From these fast blockage water-proof materials in the market, the part material has the shortcoming that the later stage shrinks, and the expansion sources that mostly adopts swelling agent to shrink by way of compensation in case swelling agent control is improper, will produce untoward reaction, influences the weather resistance of buildings.Therefore from the demand of waterproofing work, develop have water-swellable, the material for quickly stopping leakage of permanent waterproof has great importance.
Summary of the invention
At the common problem of waterproofing and leakage-stopping engineering, the object of the present invention is to provide the fast blockage water-proof material of characteristics such as a kind of fast blockage, water-swellable, penetrant crystalline, microscopic checks self-healing and permanent waterproof.
To achieve these goals, the present invention adopts following technical scheme:
A kind of high-performance fast blockage water-proof material, form by silicate cement, high alumina, Potassium aluminum sulfate dodecahydrate, dihydrate gypsum, wilkinite, sodium polyacrylate, latex powder, quartz sand, each weight percentages of components is: silicate cement 24-60%, high alumina 20-63%, Potassium aluminum sulfate dodecahydrate 0-10%, dihydrate gypsum 1-5%, sodium polyacrylate 0-1%, wilkinite 2-10%, latex powder 0-2%, quartz sand 10-20%.Described high aluminium cement clinker can be the high alumina of high oxidation iron.Potassium aluminium sulfate, dihydrate gypsum, sodium polyacrylate can adopt the product of technical grade, but fineness should be more than 40 orders.
Above-mentioned each component can be prepared from the fast blockage water-proof material by following preparation technology.After this product and a certain amount of water mix and stir, the slip that forms final set just is very short pitch time, have that fast blockage, water-swellable, penetrant crystalline, cohesive force are strong, characteristics such as microscopic checks self-healing and permanent waterproof also can solidify rapidly in water, intensity is very high, can construct under water.
Wherein, cement can be silicate cement, ordinary Portland cement, slag or portland-pozzolan cement, but its intensity should be not less than 42.5 strength grades;
Polymer emulsion powder can be an ethene-vinyl acetate emulsion copolymer powder, also can be the acrylic acid or the like latex powder;
Wilkinite can adopt calcium base or sodium bentonite, and fineness is at 100 orders or following;
Quartz sand also can adopt common yellow ground or river sand, and particle diameter and grain composition should meet between the 40-100 order.
Each component optimum weight per-cent is: silicate cement 25%, high alumina 48%, Potassium aluminum sulfate dodecahydrate 4%, dihydrate gypsum 2%, sodium polyacrylate 0.1%, wilkinite 5%, latex powder 0.9%, quartz sand 15%.
This fast blockage waterproof is the fundamental property based on high-alumina cement, silicate cement, when admixtures such as gypsum exist, be formed with expansile crystallization hydrate after reacting fast with water, it is the aquation calcium sulphoaluminate, make the aquation body produce microdilatancy, be filled in slit or the hole and the stress of object generation all around with it, and cement slurry self densification, thereby this cement just can not produce shrinkage crack in the junction.The setting and harden time is very short.Simultaneously, active substance is produced crystal and is penetrated in the hole of slurry under the effect of moisture, and when infiltrating with water once more, wilkinite and sodium polyacrylate can expand rapidly, fill the crack of secret room infiltration, and form the gel of certain intensity.Having under the situation of water, active substance infiltrates inside concrete once more, plays impervious, waterproof action.
The preparation method of product of the present invention is: each powder component by above-mentioned raw-material requirement, is prepared, and the free water content of each component is controlled at below 0.5%.Press formula rate and add required silicate cement, high alumina, Potassium aluminum sulfate dodecahydrate, dihydrate gypsum, wilkinite, sodium polyacrylate, latex powder, quartz sand, in stirrer, stir, form product.
Water-proofing material for stopping leak of the present invention has fast solidifying, hour intensity height, microdilatancy, can be widely used in engineerings such as the various leak stopping sealings of water, repairing, can be with the water pressure sealing.The cohesive force at this product and various interfaces is strong.Have re-expanding when meeting water, from the performance of shutoff; Performance with penetrant crystalline, permanent waterproof, this product is nontoxic, tasteless, pollution-free, the nothing burning, the chemicals-resistant corrosion.
Embodiment
High-performance fast blockage water-proof material is made up of silicate cement, high alumina, Potassium aluminum sulfate dodecahydrate, dihydrate gypsum, wilkinite, sodium polyacrylate, latex powder, quartz sand.Concrete enforcement in the engineering according to the environment of applications condition, by adjusting the prescription of invention, can obtain needed performance.Its span and example see the following form:
