Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of strong concrete interfacial agents and its preparation side
Method.
Background technique
In the construction, transformation and reinforcing engineering in bridge, tunnel and house, the knot at new-old concrete interface is often referred to
Conjunction problem, according to the correlation theory at interface it is found that the combination of material is in interface be it is most weak, most of destroy all occurs to exist
Interface or since interface.The quality of new-old concrete interface cohesion directly influences the quality problems of construction work, such as
Fruit interfacial adhesion is inadequate, just will appear such as and phenomena such as crack, stick up skin, peel off occurs, make it is integrally-built using function and
Safety is damaged again.
Concrete interface agent is also known as interface bonding agent, interfacial agents.Interfacial agents used in engineering mainly have cement net at present
Slurry, expanding cement net slurry, epoxy glue, polymer-modified cement mortar etc., wherein polymer-modified cement mortar is by cement, bone
Material, high molecular polymer binding material and various auxiliary agents are formulated, and are the novel binder course processing after a kind of modified-high polymer
Material, can be formed after hydration reaction has larger bonding force and high-strength hardenite with a certain toughness with concrete, is application
Increase a kind of finish materials of functional material in long concrete wall or concrete surface, new and old coagulation can be increased
Bonding force between soil and between concrete and plastering mortar can replace traditional dabbing process, accelerate construction progress,
The adhesion strength of new-old concrete is directly related to the quality of concrete after repairing, reinforcing.China applies concrete interface at present
Mainly there is mortar base, concrete base layer, old wall floor tile base, various materials for wall bases, non-in the base of processing material
Metal veneer and decoration panel base, heat preservation styrofoam base etc..
Nevertheless, but the concrete interface agent in practical engineering application to there is adhesion strength mostly low, corrosion resistance,
Water resistance, durability and low temperature flexibility are poor, easily come unglued, crack under wet environment, falling off, hollowing the problems such as.Newly, old concrete
Adhesive surface has in the identical material of new, old concrete and similar internal structure, and for macroscopically, adhesive surface is by mixing always
Three phase materials of solidifying soil, novel concrete and interfacial agents composition, during Frozen-thawed cycled, positive and negative due to temperature alternately changes,
Alternate tensile stress is generated on pore periphery, so that adhesive surface is damaged, caused by Frozen-thawed cycled to certain number
When tensile stress reaches the adhesion strength at interface, adhesive surface will generate microcrack, and with the development of microcrack, perforation causes to glue
Junction is destroyed.
Traditional processing method is to carry out dabbing processing, to increase the bond area of concrete mortar and the base that constructs, from
And cohesive force being improved, but the processing method can only solve the problems, such as local, effect is less desirable, and time-consuming.Have at present
Concrete interface agent after dry powder-shaped concrete interface agent or polymer dispersion liquid and cement mixing.But dry powder-shaped coagulation
Soil Interface agent adhesive property is general, and waterproof performance is poor;And the concrete interface agent after polymer dispersion liquid and cement mixing
Dry very fast, easy cracking.
With the continuous development of architecture construction technology, bamboo (wood) glued board, industrializes template system at large-scale steel form
It is widely applied, although the concrete work seam surface finish and impression quality that are formed by concrete substage construction constantly mention
Height, but it is next difficult with concrete surface adhesive tape to later process such as concrete surface plasterings, this kind of surface is usually adopted
Manually dabbing is pocessed after rinsing.But such processing mode is long in time limit, cost is high, construction quality is difficult to reach design and want
It asks, building easily forms weak link at construction joint position or leaves hidden danger, jeopardizes the safety of building when serious.Therefore, it opens
Issue that a kind of cohesive force is strong, waterproof performance is excellent, operable time is long, splitting resistance is good, can be applied to oil pollution basal plane
Concrete interface agent it is necessary.
