The water repellent agent provided by the invention has strong permeability, and the use method is very simple. The nano-water repellent agent only needs to be sprayed to building surfaces by a low pressure sprayer or mixed into cement mortar and concrete, and then water is added into the mixture to perform stirring for use. The nano-water repellent agent provided by the invention has the advantages of extensive use, simple construction and low cost, and its air permeability, weatherability and impermeability greatly improve the building environment, and prolong the service life of buildings.

Description

A kind of nano water-proof impervious agent and production method thereof

Technical field

The invention belongs to building trade technical field, in particular a kind of architectural waterproof material.

Background technology

Buildings waterproof is as disguised engineering, though do not account for building body major portion, but leakage of building has become the second largest problem that affects construction quality except building structure, especially huge on the impact of owner-occupation quality, seepage is also called building " cancer ", the importance of visible waterproofing work in building structure.The main externalities that affects concrete durability has: 1, unfreezing; 2, the erosion of chemical mediator; 3, reinforcement corrosion; 4, the chemical reaction gathering materials; 5, wearing and tearing; 6, human factor etc., as long as these factors cause enough attention, takes corresponding measure, it can be dropped to minimum at impact on weather resistance, and internal factor is the performance of first-elected material itself.

At present, the architectural waterproof material of most domestic is old-fashioned three floors of tarred felt and four floors of tar and new-type waterproof roll, and three floors of tarred felt and four floors of tar is because it is seriously polluted, construction is complicated especially, high in cost of production shortcoming Yi Bei Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD) below forbids to use.New-type coiled material a great variety, but these materials are cover type waterproof, complex region should not be constructed, and not ageing-resistant, and climate, temperature affect roofing and produce and expand with heat and contract with cold through several times freeze thawing, and breach is very easily thrown off by coiled material and basic unit, causes hollowing phenomenon.Joint is easy to crack, and if any place's seepage, water route is communicated with often causes large-area leaking, and is difficult for finding drain-source.

Summary of the invention

The object of this invention is to provide a kind of nonpoisonous and tasteless, non-volatile, do not burn, for a long time, efficiently, the novel rigid water-proof material of environmental protection, it can be used as gas permeability waterproof anti-permeability agent, concrete additive is used, of many uses, construction is simple, cost economy, its gas permeability, weathering resistance, impermeability has been improved buildings environment greatly, extends the work-ing life of buildings.

Concrete technical scheme of the present invention is:

A nano water-proof impervious agent, is characterized in that, it is to be made by the raw material of following weight proportioning:

Methyl-monosilane 5-20 part, sulfuric acid 1-10 part, sheet alkali 5-20 part, water 10-100 part.

A production method of manufacturing described nano water-proof impervious agent, is characterized in that, comprises the steps:

A. by described formula rate, methyl-monosilane, sheet alkali and water are mixed, stir 20-30 minute;

B. disperse reaction 4-5 hour;

C. to disperseing reacted mixture to add the sulfuric acid of described formula rate, carry out neutralization reaction;

D. then with filter, filter above-mentioned reactant;

E. the polymkeric substance after filtering heats 5-10 hour in well heater, and temperature is controlled between 70-120 ℃;

F. the polymkeric substance after heating is fully stirred;

G. disperse again reaction 2-3 hour;

H. reaction is distributed into bucket and obtains product after finishing.

Waterproof anti-permeability agent provided by the invention is the important breakthrough that Building Trade in China waterproof field is obtained, and has reached international most advanced level, is the renewal product of conventional waterproof material.It is with methyl-monosilane, sulfuric acid, sheet alkali and water, is mixed in proportion, stirs, disperses, the processing method such as neutralization, filtration is processed into.Formula of the present invention and preparation technology are unique, gas permeability waterproof anti-permeability agent, the concrete additive making by above-mentioned processing step be a kind of nonpoisonous and tasteless, non-volatile, do not burn, the colourless or weak yellow liquid non-stimulated to skin, of many uses, construction is simple, cost economy, is applicable to each field waterproof of building, once construction, lifelong waterproof, with the same life-span of buildings.Waterproof anti-permeability agent of the present invention has very strong perviousness, and using method is extremely simple, only need with low-pressure sprayer be sprayed at building surface or mix sand-cement slurry, concrete adds water and stirs.This waterproof anti-permeability agent has very strong perviousness, in the time of on being sprayed at building surface, can infiltrate rapidly its inner 10-30mm, alkaline matter inner with it produces dehydrated crosslinking effect, portion expands rapidly within it, resultant can stop up or oversite concrete, the capillary channel staying when the micropore of sand-cement slurry inside and moisture evaporation, thereby improve its degree of compactness, form environment-friendly type that is not only ventilative but also hydrophobic together and breathe the stealthy waterproof layer in interface, do not form surface and be coated with envelope, reaching can waterproof, the magical effect of penetrating gas again, produce efficient waterproof, impervious, hydrophobic, efflorescence prevention, uvioresistant, guarantor's look is kept a public place clean, the effect of acid-alkali-corrosive-resisting, in mixing sand-cement slurry, concrete, as additive, use, can realize closely knit antifreezely, prevent infiltration, improved construction quality, extended buildings work-ing life.
