Description
Technical field
The invention belongs to Metal surface anticorrosion technology fields, and in particular to a kind of to improve screw thread steel concrete bond property
Water-based antirust agent.
Background technique
Screw-thread steel is surface reinforcing bar with ribbing, also known as Ribbed Bar, is usually uniformly divided with 2 longitudinal ribs and along its length
The cross rib of cloth.Ribbed Bar is primarily subjected to tensile stress in concrete.Effect and concrete of the Ribbed Bar due to rib have larger
Cementitiousness, thus can preferably bear the effect of external force.Ribbed Bar is widely used in various building structure, particularly big
Type, heavy type, light thin wall and high building structure.
In recent years, in order to produce low-cost high-strength reinforcing bar, each iron and steel enterprise mostly uses Water cooling work after finish to gauge
Skill.The technique can improve tissue to a certain extent, improve the mechanical performance of reinforcing bar, but the technique is lacked there is one very big
Point, the i.e. screw-thread steel of Water cooling are easy to get rusty in storage and transportational process, this has not only seriously affected the table of screw-thread steel
Face quality, and rusty stain will cause screw thread steel surface and concrete bond strength and reduce, and seriously affect construction quality, the rust of reinforcing bar
Erosion, which becomes, influences the persistent principal element of building.Therefore, more and more screw-thread steel producers use chemical treatments pair
Screw thread steel surface carries out antirust, anti-corrosive processing.The market demand of screw-thread steel surface treating agent is huge, wherein all kinds of antirust agent account for
According to main status.Antirust agent mainly includes water-based antirust and antirust oil.Common water-based antirust is due to containing sodium nitrite
Equal carcinogens, it will damage the health of worker, while seriously polluting environment；Antirust oil can reduce screw-thread steel and concrete
Bond stress, seriously affect the performance and quality of screw-thread steel.
Currently, the technical solution of some metal surface antirusts has been disclosed in the prior art, such as publication No. is
The Chinese patent application of CN106555180A discloses a kind of coat of metal protective agent, which contains 5 weights
The ether compound of %-20 weight % is measured, 0.1 weight %-5 weight %'s contains mercapto heterocyclic compound, 5 weight %-20 weight
The carboxylic acid compound of amount %, the emulsifier of 0.001 weight %-1 weight %, the amide compound of 5 weight %-20 weight %, with
And the water of surplus.The coat of metal protective agent of the invention can significantly improve the corrosion resistance and durability of the coat of metal, prevent
Coat of metal oxidation stain does not influence the welding performance of the coat of metal, and not can cause environmental pollution.But the protective agent
The condition of immersion when to metal processing is to impregnate 3-10min at 30-80 DEG C, and the time that screw-thread steel wears hydraulic art only has several seconds
It is excellent to be so hardly formed anti-corrosion performance in short processing time under the premise of not being transformed to original process equipment for clock
Protective film finally seriously affects the corrosion resisting property of screw-thread steel.
Therefore, it researches and develops a kind of short processing time and improves processing rear thread steel corrosion resisting property and concrete bond property
Water-based antirust agent is of great significance.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a kind of short processing time and after improving processing
The water-based antirust agent of screw-thread steel corrosion resisting property and concrete bond property.For achieving the above object, the present invention is using following
Technical solution:
A kind of water-based antirust agent improving screw thread steel concrete bond property, is made of: 0.1wt%-5wt%'s the following raw material
1- phenyl -5- mercapto tetrazole, the acetic acid of 2wt%-5wt%, the peregal of 0.01wt%-0.1wt%, 1wt%-3wt%
N,N-dimethylformamide, the tert-butylhydroquinone of 0.1wt%-0.3wt%, 0.1wt%-0.3wt% 4- sulfo group neighbour's benzene
The water of diacid and surplus.
Preferably, a kind of water-based antirust agent improving screw thread steel concrete bond property, is made of: 2wt% the following raw material
1- phenyl -5- mercapto tetrazole, the acetic acid of 3wt%, the peregal of 0.05wt%, 2wt% N,N-dimethylformamide,
Tert-butylhydroquinone, the 4- sulfo group phthalic acid of 0.3wt% and the water of surplus of 0.1wt%.
A kind of preparation method of the water-based antirust agent of raising screw thread steel concrete bond property of the invention is simple, will be each
Raw material, which is added to the water, to stir evenly.
A kind of processing method of the water-based antirust agent of raising screw thread steel concrete bond property of the invention, specifically: it is straight
It connects and water-based antirust agent of the present invention is added in the water that original thread steel wears hydraulic art, so that mass concentration is 3 ~ 5%, wear at water
The aqueous temperature of reason is 20-100 DEG C, and screw-thread steel is passed rapidly through from aqueous solution, and the time of contact with aqueous solution is 3-10 seconds.
The present invention improves the water-based antirust agent of screw thread steel concrete bond property compared with prior art, and rust-proof effect is aobvious
Work, outdoor resistance to atmosphere and raindrop erosion are had excellent performance, while can improve screw-thread steel and concrete after antirust treatment to a certain degree
Bond strength.

Every group of 3 screw thread steel curved beam are laid flat 2 months roof is outdoor simultaneously.In the two middle of the month rainfalls 7, rainwater weather is total
23 days.During the test, observation steel surface gets rusty situation daily, and the final feelings of getting rusty of record when test in 2 months is completed
Condition the results are shown in Table 1.
Comparative test 2: screw thread steel concrete bond property test
Every group of 3 screw thread steel curved beams, screw thread steel sample is embedded in 150mm × 150mm × 150mm concrete test block, is pressed
After molding and the maintenance process maintenance of professional standard concrete sample after age, according to DL/T 5150-2001 " concrete for hydraulic structure
Testing regulations " reinforcing bar and the inspection of concrete bond strength are carried out, it the results are shown in Table 1.
1 comparative test result of table
| Test group | Average corrosion area | Bond strength average value |
| Blank group | It corrodes area and is greater than 99% | 9.7 MPa |
| Embodiment 1 | Area is corroded less than 1% | 11.1 MPa |
| Comparative example 1 | Corrode area 50%-55% | 7.8 MPa |
| Comparative example 2 | Corrode area 30%-35% | 8.4 MPa |
| Comparative example 3 | Corrode area 20%-25% | 8.9 MPa |
| Comparative example 4 | Corrode area 10%-15% | 9.3 MPa |
| Comparative example 5 | Corrode area 25%-30% | 8.2 MPa |
| Comparative example 6 | Corrode area 20%-25% | 9.6 MPa |
It can be seen that from the comparative test result of table 1 and wear water process by 1 water-based antirust agent of the embodiment of the present invention and substantially increase
The performance of screw-thread steel resistance to atmosphere and raindrop erosion, while the bond strength of screw-thread steel and concrete is improved.
Component changes in the antirust agent of comparative example 1-6, cause antirust agent resistance become rusty effect substantially reduce, while also to screw-thread steel with
The bond stress of concrete causes different degrees of influence.
The above is merely preferred embodiments of the present invention, practical range not for the purpose of limiting the invention.That is Fan Yiben
Equivalent changes and modifications made by the content of patent application the scope of the patents all should be technology scope of the invention.
