The fields such as room, tunnel, swimming pool.After concrete hardens under the conditions of general maintenance, it is easy to occur seeping water or drainage, because
This solves the problems, such as that concrete water-proof is impervious particularly significant.Concrete waterproofer has the function of very big in terms of preventing water infiltration.
Waterproofing agent experienced the development of pitch, polyurethane resin, polyacrylic acid and polyacrylamide polymers, inorganic infiltration salt etc.
Journey.Wherein, pitch and polyurethane resin type waterproof material be because seriously polluted, and containing toxic, is prohibited by country；Propylene
Acid and acrylamide polymer class waterproof material persistence are poor, are easy aging, and the service life is short, once in addition, membrane waterproofing is destroyed,
Leakage phenomenon is occurred with regard to horse back.Patent CN201810116545.7 discloses a kind of waterproof material and its system for building construction
Preparation Method, the patent is using raw materials such as epoxy resin, polyurethane, quartz sand, pitch, zirconium dioxides, although having centainly
Waterproof effect, but service life is not grown.Patent CN1800291 discloses a kind of water-proofing material for stopping leak, the water-proofing material for stopping leak
It is portland cement 24-60%, high alumina 20-63%, Potassium aluminum sulfate dodecahydrate 0-10%, dihydrate gypsum by weight percent
1-5%, Sodium Polyacrylate 0-1%, bentonite 2-10%, latex powder 0-2%, quartz sand 10-20% composition, although in the short time
It is interior to have effects that slow down water infiltration, but after long-time use, water still is able to penetrate into quickly.Patent CN108359292A
A kind of preparation method of cement group water-proofing material is disclosed, and party's material is with water, ethyl alcohol, silane coupling agent, sodium bentonite and hydrogen
Sodium oxide molybdena etc. is raw material, not only complex process, but also waterproof effect is undesirable.Inorganic waterproofing agent main component has villaumite, chlorine
Lithium hydrochlorate, sulfate, waterglass, mineral powder etc., it is different degrees of due to haveing the shortcomings that, it is anti-to be difficult to meet concrete construction engineering
The impervious needs of water.CN106904928A discloses a kind of water-borne permeable crystalline waterproofing material that reaction speed is controllable, this is anti-
Water material is mainly by sodium metasilicate, surfactant, response delay agent, reducing agent, reaction promoter, anti-freeze agent, metal ion
Agent is blocked, surface hardening agent, antirust agent, deionized water is constituted, long although having certain waterproof ability in a short time
The decline of phase waterproof effect, and complicated composition, it is at high cost.
Summary of the invention
The present invention in view of the shortcomings of the prior art, has developed a kind of preparation method of high performance waterproof infiltration material, should
Material is configured by silicate, ethyl potassium silicate, fatty acid salt, nano silica, polyvinyl alcohol, additive etc., is had
Good waterproof penetrates into effect.
The specific technical proposal is:
A kind of concrete anti-seepage agent, the mass ratio of each ingredient of the permeability-reducing admixture are as follows: silicate 1.0-8.0wt%, ethyl silicic acid

17.5wt%, 0.02~0.09wt% of additive, water 40.0-91.5wt%.
Further, above-mentioned additive is sodium citrate, laureth sodium sulfovinate, borax, according to mass ratio 1:
4:0.1 the mixture being configured to.
Further, above-mentioned silicate is at least one of sodium metasilicate, potassium silicate, silicic acid ammonia.
Further, the molecular weight of above-mentioned polyvinyl alcohol is 1-3 ten thousand.
Further, the average particle size of above-mentioned nano silica is 50-120 nanometers.
The preparation method of above-mentioned concrete anti-seepage agent comprises the following steps that the mass ratio according to each ingredient of permeability-reducing admixture, first
Polyvinyl alcohol is weighed, is dissolved in 80-90 DEG C of hot water；Then silicate, ethyl potassium silicate, sodium soap are sequentially added, is stirred
After mixing uniformly；Additive is added, continues to stir evenly；It is eventually adding nano silica, continues stirring 5 minutes, is made mixed
Solidifying soil permeability-reducing admixture.
The permeability-reducing admixture is directly sprayed when in use or is brushed in needing to do water-proofing treatment by the application of concrete anti-seepage agent
Concrete surface, just there is after 4-6min good waterproof effect.
Beneficial effects of the present invention are that the waterproofing agent is easily penetrated into concrete, can not only be crammed in concrete
Outer micropore, and it is capable of the surface of concrete and inside is formed simultaneously hydrophobic layer, the infiltration of water is prevented, therefore can be effective
Ground prevents the infiltration or infiltration of water.
