Abstract

The invention relates to an inorganic cement capillary crystalline waterproofing agent and a production process thereof. The organic cement capillary crystalline waterproofing agent is prepared from silicon ash, sodium silicate, bentonite, pulverized fuel ash, polypropylene fiber and a sulfonate water reducer by a certain percentage proportion. The production process sequentially comprises the steps of compounding, feeding, mixing, inspecting, packaging and warehousing. The organic cement capillary crystalline waterproofing agent has the advantages of capillary crystalline, waterproofing performance, durability, denseness, leaking stoppage and the like and can be widely used for waterproofing systems comprising building outer walls, basements and the like, especially for negative side waterproofing systems.

Description

Inorganic cement capillary crystalline waterproofing agent and production technique thereof
Technical field
The present invention relates to a kind of architecture engineering material, especially a kind of for exterior wall in the building structure, bridge floor, tunnel, dam, motorway, cementitious capillary crystalline waterproofing agent and the production technique thereof of flat, facade waterproof mending-leakage of inferior concrete structure building.
Background technology
Along with being on the increase of development of construction and underground and dam engineering, people have proposed more and more higher requirement to the waterproof of buildings and protection against the tide, the impregnating material of underground works.Architectural waterproof material is the important component part of construction work, and the good and bad degree direct influence of its performance the work-ing life of building and used function.With respect to traditional water-proof material, cement based penetration crystallization type water proofing paint in a lot of fields, particularly the waterproofing works such as underground waterproof engineering, back side engineering and water reservoir have irreplaceable superiority, it has solved the construction difficult problem of conventional waterproof material, improved the water resistance of waterproofing work, reduce the comprehensive cost of waterproofing work, satisfied the requirement of modern building to weather resistance.
At present, cement based penetration crystallization type water proofing paint mainly is external patented products, and home products mostly is external import, or the product that partly domesticizes of reprocessing from external import masterbatch.Be CN101654351A such as China Patent No., it mainly adopts the permeable crystallization type masterbatch to be configured, because expensive, thus its utilization in waterproofing work hindered.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of inorganic cement capillary crystalline waterproofing agent for cement, concrete or waterproofing work coating, this inorganic cement capillary crystalline waterproofing agent has waterproof, high impervious, self-healing, low, the environmental protection of cost, and validity period is longer.
This invention is achieved through the following technical solutions:
The agent of a kind of inorganic cement base infiltration crystallization type water-proof is comprised of silicon powder, water glass, wilkinite, flyash, polypropylene fibre and sulfonate water reducer, and its proportioning is silicon powder 25 ~ 50%; Water glass 5 ~ 15%; Wilkinite 0 ~ 17%; Flyash 32 ~ 48%; Polypropylene fibre 0 ~ 1.2%; Sulfonate water reducer 3 ~ 15%.More excellent proportioning is: 30 ~ 45% silicon powders, 5 ~ 12% water glass, 0 ~ 12% wilkinite, 35 ~ 45% flyash, 0.2 ~ 1.2% polypropylene fibre, 6 ~ 12% sulfonate water reducers.
The production technique of cementitious capillary crystalline waterproofing agent is successively: batching: prepare burden according to above-mentioned prescription; Feeding: each raw material is transported to stirrer; Spice: raw material stirring is even by stirrer; Check: the physics and chemistry performance that checks compound; Packing warehouse-in: with qualified cementitious capillary crystalline waterproofing agent packing warehouse-in.
The present invention is the cementitious capillary crystalline waterproofing agent that a kind of active chemical components, diminishing thickening composition and expansion component form.Its active chemical components can permeate and spread to mortar, concrete inside under the effect of water, forms a large amount of water-soluble crystal in hole and crack, the passage of filling and shutoff water, thus reach effect closely knit and waterproof, protection against the tide.Owing to adopted industrial residue, reduced cost, and considered that all kinds of raw-material characteristics are complementary, Optimization, thus reached the fine quality of stable performance.The cementitious capillary crystalline waterproofing agent of producing according to the method described above can mix and be mixed with high impervious waterproof mortar or water-proof concrete in mortar, the concrete, also can add cement, quartz sand etc. and stir the production cement based penetration crystallization type water proofing paint, be used for waterproofing work, also can be used for filling up the crack that concrete produces in earlier stage constructing.
The present invention has unique performance:
The high permeability resistant energy;
The self-healing performance of microfracture;
Nontoxic, can be used for water works;
Inorganic materials, high-durability;
Adopt industrial residue, low, the environmental protection of cost.
