Description
Technical field
The invention discloses a kind of special adhesives of FRP reinforced concretes, belong to concrete structure recovery technique field.
Background technology
FRP composite materials are a kind of advanced composite material (ACM)s reinforced applied to civil engineering structure.Since FRP has many
Well-known advantage（Lightweight, high-strength, corrosion resistant etc.）, many scholars of building circle and engineers are wide by it during the nearly last ten years
It is general to be applied to structural fortification, and carried out a large amount of research work.Carrying out the most common method of structural strengthening using FRP is
By FRP cloth（Including sheet material）It is pasted onto the surface for reinforcing position, FRP tendons can also be used（Bar）Embedding be attached to reinforces position surface layer
In concrete pit（In concrete cover）.Obviously, no matter which kind of reinforcement means is used, between FRP and concrete structure faying face
Adhesion strength be influence structural strengthening after performance a key factor.Actually, many FRP reinforced concrete structures are all
It is destroyed because of interface peel.Therefore, the bonding mechanism between FRP and concrete is FRP reinforced concrete structures research neck
One important topic in domain.In addition to this, carbon fiber（CFRP）Under anoxic condition, physical and mechanical property does not wane within 1000 DEG C
Subtract；The mating adhesive of currently used reinforcing is mostly epoxies organic gel, and thermal stability and long-term chemical durability are poor, especially
It is that its maximum operation (service) temperature is only 82 DEG C, it is difficult to meet engineering fire-resistance needs.Therefore, a kind of high-temperature resistant structural adhesive replacement is developed
The epoxies organic gel of low softening point, is beneficial to the further genralrlization of FRP reinforcement techniques
Therefore, it is bad how to improve traditional FRP reinforced concretes adhesive anti-shear performance, the shortcomings that poor flame retardant properties, to obtain
The FRP reinforced concrete adhesives for taking more high combination property are that it is promoted and applies, it is urgently to be resolved hurrily to meet industrial production demand
Problem.
Invention content
The present invention solves the technical problem of：It is bad for traditional FRP reinforced concretes adhesive anti-shear performance,
The shortcomings that poor flame retardant properties, provides a kind of special adhesive of FRP reinforced concretes.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：

Part potassium hydroxide solution, 30~40 parts of hydroquinone constant temperature are stirred to react, and are cooled down, and 0.2~0.3 times of glutaraldehyde solution volume is added
Ethylene urea be stirred to react, cool down, the Silane coupling reagent KH-570 that 0.1~0.2 times of glutaraldehyde solution volume is added is stirred to react,
Cooling is to get alkalescent phenol resin.
The beneficial effects of the invention are as follows：
The present invention is by adding Phanerochaete chrysosporium bacterium solution and modified seaweed acid solution, in use, first, yellow archespore hair
Flat lead fungi metabolism generates organic acid and carbon dioxide, and organic acid has corrosiveness to original concrete, meanwhile, carbon dioxide is molten
It is agglomerated in moisture film in concrete surface, forms carbonic acid, carbonic acid also has corrosiveness to original concrete, on the one hand, so that mixed
Solidifying soil surface is more coarse, and epoxy resin can be soaked preferably, spread over concrete surface, with this reinforced epoxy and base
Adhesion strength between body concrete, to improve the shear strength of product, on the other hand, microcorrosion acts on so that internal mixed
Solidifying soil is exposed, and the internal further aquation of concrete is promoted so that a large amount of calcium ions are generated in system, and calcium ion is desirable
For the sodium ion in modified sodium alginate, modified sodium alginate is promoted to be crosslinked, forms three-dimensional network, under fire hazard environment,
Calcium ion in system is thermally generated calcium carbonate, the carbon dioxide and oxidation that the calcium carbonate of generation is further generated by thermal response
The carbon dioxide of calcium, generation plays the role of good barrier oxygen, to promote the flame retardant property of product；Furthermore the oxygen of generation
Change calcium to be distributed in system, further promotes the flame retardant property of product, secondly, in the case where heating alkaline condition, modified seaweed acid solution
In aldehyde radical and the silicone hydroxyl of fiberglass surfacing aldol condensation occurs, enhance the adhesion strength between adhesive and FRP, into
One step promotes the shear strength of product.

The special adhesive of FRP reinforced concretes of 1 to 5 gained of example and comparative example product are subjected to performance detection, it is specific to detect
Method is as follows：
Anti-shear performance：Concrete surface is polished flat, the weaker zone of concrete surface is removed, it is new to expose concrete structure
Face wipes the impurity such as surface layer floating dust, greasy dirt with acetone, and concrete surface is kept to moisten, spare；FRP cloth is cut out on demand, and
Inorganic glue is prepared with preferred ingredient, then inorganic glue is poured into and infiltrates FRP cloth in slot type receptacles, smooth roomy roller is used in combination
FRP cloth 15min is smash along unidirectional pestle；2mm thickness primers are brushed in concrete surface, FRP cloth is pasted onto down by one that pestle is smash
Concrete surface is used in combination plastic scrapers to squeeze out bubble, brushes 2mm thickness face glue；By test block be put into standard curing room be cured to it is predetermined
After age, double shear experiment is carried out, tests test specimen in-plane shear strength.
Specific testing result is as shown in table 1：
Table 1：The specific testing result of anti-shear performance
| Detection project | Example 1 | Example 2 | Example 3 | Example 4 | Example 5 | Comparative example |
| In-plane shear strength/MPa | 1.69 | 1.37 | 1.02 | 1.28 | 0.99 | 0.65 |
By 1 testing result of table it is found that the special adhesive of FRP reinforced concretes prepared by technical solution of the present invention has excellent resist
The characteristics of cutting performance, has broad prospects in the development of concrete repair materials industry.
