Description
Technical field
The present invention relates to concrete curing technical field, and in particular to a kind of moisture absorbing resin type sealing compound and its preparation side
Method.
Background technology
Distress in concrete by produce the reason for mainly have load Crack and non-loaded deformation, substantial amounts of engineering shows coagulation
The humiture that soil structure crack is mainly by concrete in itself or environment is converted, the crossing of environmental attack act on it is lower produce it is non-
What load stress caused, and the main self-constriction of the main source of non-load stress and dry contraction, both of which is by concrete reclaimed water
The consumption for dividing causes.Having studied at present cause cracking to be asked because of lack of moisture solving concrete by being conserved in concrete
Topic.Conserving material is added in concrete, when the humidity of concrete declines, conserving material discharges moisture and supplemented, and has
Effect solve concrete because self-constriction and drying is shunk cause split problem.
Curing compound can influence the performances such as concrete anti-compression, frost resistance, permeability in application process, current
Construction in, the performance requirements more and more higher such as crushing resistance, bleeding rate to concrete, by sealing compound technology
Research, optimised coagulation soil maintenance agent prescription, improves the performance of concrete, could meet the demand in market.
The content of the invention
It is an object of the present invention to be directed to prior art, there is provided a kind of moisture absorbing resin type sealing compound and preparation method thereof.
To achieve the above object, the present invention takes following technical scheme：
A kind of moisture absorbing resin type sealing compound, it is made up of the following raw material of mass parts：Natural 5~15 parts of soil of grafting skeleton,
0.1~2 part of N, N- methylene-bisacrylamide, 10~15 parts of initiator, 1~15 part of microcrystalline cellulose, acrylamide 10~20
Part, 40~60 parts of deionized water.
Wherein, described grafting skeleton soil is one or more of bentonite, kaolin, attapulgite, potter's clay, described
Initiator for potassium persulfate, ammonium ceric nitrate one or more.
Wherein, in concrete batching material, addition is the material that is gelled in concrete material to described moisture absorbing resin type sealing compound
The 0.01%~0.1% of material gross weight.
Further, its preparation method is comprised the following steps：
(1) will naturally be grafted skeleton soil to mix with microcrystalline cellulose, and add and be dissolved in initiator after deionized water, at 50 DEG C
Stirring 15min, then acrylamide is dissolved in after water after stirring reaction 1h at 50 DEG C, add N, N- methylene-bisacrylamides
Continue to stir at 50 DEG C, be placed in micro-wave oven, in power for 200~300W microwaves are molded；
(2) article shaped that step (1) is obtained is placed in 30~60min of immersion in absolute ethyl alcohol, baking oven is then placed into, in 80
~100 DEG C of 6~8h of constant temperature drying, obtain moisture absorbing resin type sealing compound；
(3) moisture absorbing resin type sealing compound is crushed with pulverizer, then is sieved with bushing screen, cross 80 mesh sieves, just can obtain graininess suction
Water tree epoxy-type sealing compound.
With N-N methylene-bisacrylamides as crosslinking agent, ammonium ceric nitrate, potassium persulfate are initiator to the present invention, will be micro-
Crystalline cellulose forms high absorbency material with acrylic amide graft copolymerization, and water imbibition is strong.
Microcrystalline cellulose graft acrylamide is had a water imbibition very high by the present invention, and with bentonite, kaolin, concavo-convex
Any one or a few is combined in rod stone, potter's clay, it is to avoid traditional fibre element graft acrylamide resin is because of itself soft, crinosity
The drawbacks of characteristic causes concrete crushing strength to weaken, maintainers of the invention in the application, improve the crushing resistance of concrete, together
When bentonite, kaolin, attapulgite, potter's clay be cohesive soil, sealing compound application when mix concrete material in, stir,
The Yi Hexing of concrete can be improved.
The beneficial effects of the invention are as follows：
1st, hydroscopicity resin sealing compound water absorption rate of the invention is high, gelling water absorbing properties are good, ensure the humidity of inside concrete, tool
There is anti-cracking performance higher；
2nd, the even particle size of sealing compound of the invention, particle spends 80 mesh, when sealing compound dehydration, can the change of sealing compound particle
It is small, bubble of uniform size can be formed in inside concrete, improve the frost resistance of concrete；
3rd, sealing compound of the invention can improve the compression strength and Yi Hexing of concrete；
4th, sealing compound of the invention is environment-friendly, with low cost, beneficial to environmental protection；
5th, maintainers of the invention need not water, and can largely save maintenance water and reduce human and material resources input, reduce additional
The application cost of agent.
