Description
Technical field
The invention belongs to the care field of construction site concrete, be specifically related to a kind of rapid-hardening curing compound.
Background technology
Along with the development of society, the scale of urban architecture is increasing, the building sides that the particularly near more than ten years are Chinese
Long-pending and scale ranks first in the world, and house, highway, bridge, high ferro construction etc. are required for using concrete, have one after concrete construction
Individual natural hydration process, but as time went on, the moisture in concrete constantly runs off, and hydration reaction is incomplete, is easily generated and splits
Seam, affects construction quality, causes potential safety hazard.Generally use periodically water spray to guarantee that hydration reaction is complete, but this process needs
Expending substantial amounts of manpower, material resources and financial resources, using chemistry health-preserving method that concrete carries out water-preserving curing is to traditional methods to keep in good health's method
Innovation, compared with traditional regimen, have saving of work and time water saving, convenient construction use superiority.Often cannot use
Rule sprinkling method carries out using on the young concretes such as the skyscraper of maintenance, highway bridge, special type structure concrete curing
Agent, more demonstrates its superiority.In modern concrete construction, spary sealing compound has become the important measures of concrete curing,
How to use sealing compound, directly affects concrete engineering quality.
Curing compound is a kind of sprinkling or is painted on concrete surface, typically requires spraying twice, sprays the second layer
Can must carry out after the first tunic is completely dry during sealing compound, spraying direction is perpendicular with ground floor.Spraying is wanted uniformly, to protect
Card spraying consumption, should not cross thin or blocked up, wants in order during spraying, should not have drain spray, so form one layer of company at concrete surface
The continuous airtight or emulsion of semi-hermetic curing membrane or macromolecular solution.In concrete construction, to the coagulation newly poured
Soil is implemented effective maintenance and is to ensure that it reaches the key operation link of preferable mechanical property and reliable endurance quality.
The intensity of concrete stems from the aquation of cement, and the aquation of cement can only be carried out in the capillary tube filled by water, so supporting
The purpose protected is that creates the curing condition that concrete is good, prevents the moisture evaporation in capillary tube to scatter and disappear, it is ensured that cement
Fully aquation so that concrete strength constantly increases.In view of sealing compound kind is more in the market, quality is uneven, suitable
Limitation is had, as facade etc. can not be sprayed by scope.And most common method is watering at present, water ceaselessly to spill, especially north
Fang Xiatian and autumn, and DeGrain；Plastic covering cloth, operates bothersome, also can bring certain environmental issue.
Accordingly, it would be desirable to a kind of curing compound that can conscientiously solve the problems referred to above.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of rapid-hardening curing compound, this sealing compound
Utilize the spacial framework of hydrogel and combine the characteristic of water, by inorganic material and the combination of organic material, fully
Play cooperative effect between the two and improve the water retention of sealing compound, extend hydration, improve concrete strength.
To achieve these goals, the present invention provides a kind of rapid-hardening curing compound, and including solvent orange 2 A, its formula is pressed
Mass percent is: sodium silicate 0.2%-3.0%, polyvinyl alcohol 0.2%-2.0%, and surplus is water.
Further, also including solvent B, its formula is by mass percentage: boric acid 0.2%-2.0%, and surplus is water.
Further, described solvent orange 2 A uses and sprays or painting way, and the usage amount of solvent orange 2 A is 0.5-1L/m2。
Further, in solvent orange 2 A and solvent B different vessels to be left in, take to spray respectively or brush.
Further, when being used in conjunction with solvent orange 2 A and solvent B, first use solvent B to re-use solvent orange 2 A, or first use solvent
A re-uses solvent B, and usage amount is solvent orange 2 A by volume: solvent B=1:0.1-0.5, and the usage amount of solvent orange 2 A is 0.5-1L/m2。
After described sprinkling or brushing, film forming thickness is 3-6mm.
The using method of the rapid-hardening curing compound that the present invention provides is: according to different demands, can be used alone molten
Agent A, or it is used in conjunction with solution A and solvent B, quickly form gel at concrete surface, can use and spray or the mode of brushing.
The application of this rapid-hardening curing compound has a characteristic that
(1) it is applicable to multiple concrete construction, such as construction site, highway, bridge, high ferro etc., is applicable to various angle
The region of degree, such as plane, domatic, end face, turning and face, corner etc.；
(2) require to take different spray pattern, as only sprayed solvent orange 2 A in horizontal surface areas, by naturally oozing according to difference
Thoroughly and evaporation, layer of gel film can be formed；At facade or irregular area, for preventing solvent to run off, first spray solvent B and spray again
A, by crosslinking can fast filming, gelation becomes apparent from；
(3) film forming thickness is relevant with proportioning raw materials with speed；
(4) using and spray or painting way, equipment is simple, processing ease, instant effect, can be suitable for different condition and requirement
Job site.
In the present invention, the sodium silicate of free state has good chemism, can enter concrete surface layer micropore, and shadow
Ring its surface chemical property；Polyvinyl alcohol has the spacial framework of gel, can work in coordination with sodium silicate and stick to concrete surface,
There is water conservation and suppression dehydration double grading；Recycling boric acid can make polyvinyl alcohol crosslinked characteristic, it is achieved quick-gelatinizing,
Improve film strength and water-retaining property further.
The technical scheme that the present invention provides mainly has the feature that (one) raw material has good biocompatibility, poly-second
Enol can carry out biodegradation, environment will not be caused secondary pollution；(2) quick-gelatinizing, by crosslinking can in 5 seconds shape
