Abstract
The invention discloses a kind of anticorrosive corrosion inhibitor of two polar form of RC- and its applications; including 25~37 parts of dimethylethanolamine; 5~8 parts of sodium benzoate; 5~7 parts of sodium molybdate, 0.3~0.5 part of triterpenoid saponin, 48~65 parts of water; moderate dosage of the invention is 2%~3%; dimethylethanolamine and the long short molecular chain collocation of sodium benzoate, chelate with rebar surface iron atom, form one layer of more stable protective film on the surface of reinforcing bar in its formula.Reinforcing bar is prevented to be rusted, the Corrosion mechanism that especially cathode can be blocked to be occurred.Sodium molybdate can form passivating film in anode, have the effect of preventing to anode corrosion.The capillary channel in concrete can be closed and be blocked to triterpenoid saponin, significantly delay seepage velocity of the harmful ion in concrete, so the present invention can more greatly improve the resistance rust ability of reinforcing bar, the ability of agent on crack resistance of concrete harmful ion corrosion is improved, and can be improved the compression strength of concrete.
Description
Technical field
The invention belongs to the anticorrosive rust-prevent technology field of armored concrete, it is related to a kind of anticorrosive corrosion inhibitor of two polar form of RC-
And its application.
Background technique
Corrosion is the common phenomenon of reinforced concrete structure, drastically influences the service life of reinforced concrete structure.By
It is not closely knit enough in armored concrete, thus chloride ion or sulfate ion can be penetrated by the capillary porosity duct in concrete it is mixed
Solidifying soil inside or even chloride ion can reach the reinforcing bar position of inside concrete, and sulfate ion meeting corrosion concrete causes coagulation
The decline of soil mechanics performance, chloride ion can reach reinforcing bar position and corrosion reinforcing bar, cause the structural damage of armored concrete.?
Ocean, coastal area, this destruction in Salt Lake Area in salt-soda soil area and northwest are very serious.Armored concrete according to relevant report
Economic loss caused by structure deterioration destroys accounts for about the GDP of 2%-4%.
Currently, the method for reply steel bar corrosion mainly has both at home and abroad: carrying out antirust treatment to rebar surface and in concrete
Middle addition corrosion inhibitor both methods.The pretreated method higher cost of antirust is carried out to steel rust surface, in the ring of heavy corrosion
It is just used under border, for the environment of moderate corrosion or general corrosion, adding corrosion inhibitor in concrete can be solved problem.Mesh
Before, usually all use Anodic Type corrosion inhibitor both at home and abroad, such as Japan is based on nitrous based phosphates, China mostly with nitrite or
Based on nitrate.Such corrosion inhibitor has following shortcomings: a. can only work to the anode of steel bar corrosion, and corrode to cathode
Without effect；The effect of resistance rust is not had when b. adding insufficient；C. toxic, it is harmful to the human body, does not meet environmentally protective demand；d.
Reduce the intensity of concrete.
The U.S. newly has developed a kind of organic corrosion inhibitor of migration-type in recent years, such as ethanol amine, dimethylethanolamine, divinyl
Triamine and the condensation product of thiocarbamide etc. can densely be adsorbed on the surface of reinforcing bar, one layer of fine and close passivating film be formed, to prevent
Steel bar corrosion.Such organic corrosion inhibitor asepsis environment-protecting, resistance rust work well, and not only work to reinforced anode corrosion, more important
Be can play a part of to reinforcing bar cathode block Corrosion mechanism.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of anticorrosive corrosion inhibitor of two polar form of RC-, the corrosion inhibitor is nontoxic
Environmental protection, moderate cost can prevent reinforced anode from corroding and cathode blocked to corrode, moreover it is possible to improve the energy of agent on crack resistance of concrete infiltration
Power, and have no adverse effect to concrete strength.
The technical scheme is that a kind of anticorrosive corrosion inhibitor of two polar form of RC-, the corrosion inhibitor are matched according to following weight
Than:
25~37 parts of dimethylethanolamine, 5~8 parts of sodium benzoate, 5~7 parts of sodium molybdate, 0.3~0.5 part of triterpenoid saponin,
48~65 parts of water.
Further, the weight proportion of the corrosion inhibitor be 31 parts of dimethylethanolamine, 6.6 parts of sodium benzoate, sodium molybdate 6
Part, 0.4 part of triterpenoid saponin, 56 parts of water.
The present invention also provides a kind of application of the anticorrosive corrosion inhibitor of two polar form of RC-, the corrosion inhibitor is used for reinforced concrete
Soil structure mixes in concrete, and volume is 2%~3%.
Further, the volume of the corrosion inhibitor is 2.5%.
Further, the volume of the corrosion inhibitor is the percentage for accounting for concrete gel material total weight.
Dimethylethanolamine and sodium benzoate in inventive formulation under alkaline condition can be former with the iron of rebar surface
Son chelating forms one layer of more stable protective film on the surface of reinforcing bar.Wherein dimethylethanolamine strand is longer, mainly increases
Add the thickness for being formed by protective film, and the strand of sodium benzoate is shorter, can fill up in dimethylethanolamine strand
Portion increases the compactness for being formed by protective film, and as formed protective film can be covered on all surfaces of reinforcing bar, prevents
Reinforcing bar is rusted, and the Corrosion mechanism that especially cathode can be blocked to be occurred prevents reinforcing bar from getting rusty.
Sodium molybdate in inventive formulation mainly plays anode resistance rust, looks unfamiliar one layer of passivating film in bar list, Ke Yiqi
To the effect prevented anode corrosion.Triterpenoid saponin in formula is a kind of good air entraining agent, can be in inside concrete shape
At a large amount of small, equally distributed bubbles, capillary channel in closed concrete slows down sulfate ion and chloride ion mixed
Seepage velocity inside solidifying soil, exponentially times delay the speed that concrete is corroded, improve the resistance to corrosion of concrete.
The beneficial effects of the present invention are: corrosion inhibitor major part raw material of the present invention is organic compound, toxicity is lower, does not have to environment
There is pollution, and cost of material is moderate.Corrosion inhibitor of the present invention can play resistance rust effect from the two poles of the earth and exponentially delays to have again
Infiltration rate of the evil ion in concrete, the resistance rust ability and agent on crack resistance of concrete that reinforcing bar can be significantly increased have
The ability of evil ion etching, experiment show that the compression strength of concrete also gets a promotion.
