Description
Technical field
The invention discloses a kind of preparation methods of osmosis type bi-component concrete dense curing agent, belong to concrete additives
Technical field.
Background technology
Concrete is a kind of construction material, while it is also that tool is vital.With the development of the society, composition concrete
Material also constantly developing, the understanding that people meet material technology is also being continuously improved.At this point, for concrete
It is required that it is also higher and higher, it is no longer only limited to its measuring body degree, but under conditions of its intensity reaches standard, more
Coordination and the balance for focusing on its overall target, during concrete structure is on active service, when it is exposed to it is outer when, often
Because the quality on its surface is unqualified or density is not achieved relevant requirement and it is made to be corroded, make its structure by broken
Bad, reduced performance, the service life is reduced.And it is to improve a kind of effectively technical side of its durability to carry out application to the surface of concrete
Method, this has obtained actual application in reality in some buildings and bridge, this just needs curing sealing agent to come to it
Reinforced.
Curing sealing agent does not have color, and a kind of transparent state is presented, and construction is relatively convenient, does not poison, non-ignitable, infiltration
Power is also stronger, be it is a kind of can be with the material of the liquid of sealed-for-life concrete.Among concrete material, sealing is solid
Agent can penetrate into chemical substance possessed by its inside and concrete itself inside and certain reaction occurs, and cause to coagulate
The formation of glue so that the crack of concrete and pore shrink and then form a comparison closely entirety, to which case hardness reaches
To relevant standard and accomplished it is impervious, it is wear-resisting etc..If sealing and curing owner is so that the hardness and resistance to compression degree of earth's surface increase
By force, and it is more wear-resisting, thus effectively the invasion of environmental contaminants can be inhibited, reduce erosion of the chemical substance to it
Degree ensures its quality and performance.After being applied to concrete, its density can be enhanced, keep it impervious and anti-
The ability of grease is all further improved, and ground can be more glossy after being handled, bright degree and use
Time length be present proportional relation.But with economic development, higher is proposed to curing sealing agent in practice
Requirement, conventional seals curing agent can not meet production with application, comprehensive performance needs further increase.
Therefore, how to improve conventional seals curing agent it is small to mechanical performance of concrete and anti-permeability performance room for promotion lack
Point is that it is promoted and application, meets that industrial production demand is urgently to be resolved hurrily to ask to obtain the curing sealing agent of more high combination property
Topic.
Invention content
The present invention solves the technical problem of：For conventional seals curing agent to mechanical performance of concrete and impermeability
The small disadvantage of energy room for promotion, provides a kind of preparation method of osmosis type bi-component concrete dense curing agent.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）It after soybean is soaked in water, is transferred in incubator, constant temperature vernalization obtains vernalization soybean；
（2）It after vernalization soybean is freeze-dried, crushes, sieving obtains vernalization soy meal；
（3）It is 1 in mass ratio by vernalization soy meal and ethanol solution：10~1：After 15 mixing, after thermostatic ultrasonic extraction, it is transferred to ice
In case, 24~36h is refrigerated, then be centrifuged, collects upper liquid, then by upper liquid vacuum freeze drying, obtain extract of soybean；
（4）It is 1 in mass ratio by chitosan and water：40~1：45 mixing after, stand swelling, add chitosan mass 0.1~
0.2 times of chitosan enzyme, constant temperature stirring enzymolysis, then through enzyme deactivation, obtain Enzymatic Hydrolysis of Chitosan liquid；
（5）It counts in parts by weight, takes 20~30 parts of extract of soybean, 180~200 parts of water, 20~30 parts of Enzymatic Hydrolysis of Chitosan successively
Liquid, after being stirred, discharging obtains component A；
（6）It counts in parts by weight, 10~15 parts of urea, 100~120 parts of water, 10~15 parts of aluminates is taken to be stirred successively,
Discharging, obtains B component；
（7）Component A and B component are separately encapsulated, that is, constitute osmosis type bi-component concrete dense curing agent.
Step（1）The constant temperature vernalization condition is：Germination temperature be 20~25 DEG C, germination time be 12~for 24 hours.
Step（4）The chitosan is the chitosan that deacetylation is 90~95%.
Step（6）It is 1 in mass ratio that the aluminate, which is by potassium aluminate and sodium aluminate,：1~3：1 mixes.
The beneficial effects of the invention are as follows：
（1）Soybean is carried out vernalization processing by the present invention first, restores enzymatic activity in soya cells, then obtain soybean by extraction and carry
Take object, by adding extract of soybean, using in extract of soybean urase and phosphatide as the active ingredient of product, urase,
In use, urea can be made to be decomposed into ammonium ion and carbanion, carbonic acid with the urea haptoreaction in B component
Radical ion can be contacted with the calcium ion to dissociate in concrete system, form calcium carbonate, and once have the generation of calcium carbonate nucleus, you can
It is adsorbed by lecithin, to make calcium carbonate crystal be well dispersed in concrete pore, the filling to hole is realized, to effectively
Play the role of sealing and curing, and with the consumption of carbanion, ammonium ion increases in system, make part ammonium ion and
Hydroxide ion combines, and generates ammonia, and overflow, in ammonia overflow process, air pressure can be generated, to assist product in concrete
Diffusion in hole improves osmotic efficiency；In addition, phosphatide also has good surface-active, it can be used as emulsifier and be present in body
In system, play the role of assist infiltration；
（2）The present invention digests chitosan liquid by addition, and first, chitosan molecule can form gel in concrete hole gap structure
Secondly network carries positive charge, can attract each other with negative electrical charge in phospholipid molecule structure, to make phosphatide in chitosan molecule
It adsorbs fixed calcium carbonate crystal to be filled in chitosan gel rubber network structure, effectively promotes the packed density of gel network, and
The addition of water-soluble aluminate, may penetrate into concrete pore inside configuration, and with calcium hydroxide reaction inside system, quick shape
Under the ammonia effect that the hydrated product of Cheng Xin, the new hydrated product in part and calcium carbonate crystal can generate inside system, expand
It is dissipated to concrete surface, is cured in concrete surface, to reduce surface porosity factor, improves concrete strength, and portion gas
It is mothballed inside system, and higher vapour lock is formed in a small amount of residual porosity inside concrete system, effectively avoid external
Erosion of the substance to inside concrete.

0.2 times of chitosan enzyme, constant temperature stirring enzymolysis, then through enzyme deactivation, obtain Enzymatic Hydrolysis of Chitosan liquid；
（5）It counts in parts by weight, takes 20~30 parts of extract of soybean, 180~200 parts of water, 20~30 parts of Enzymatic Hydrolysis of Chitosan successively
Liquid, after being stirred, discharging obtains component A；
（6）It counts in parts by weight, 10~15 parts of urea, 100~120 parts of water, 10~15 parts of aluminates is taken to be stirred successively,
Discharging, obtains B component；
（7）Component A and B component are separately encapsulated, that is, constitute osmosis type bi-component concrete dense curing agent.
