Abstract

The invention discloses a concrete rust inhibitor. The concrete rust inhibitor comprises the following components in parts by weight: 1-8 parts of sodium molybdate, 300-500 parts of diethylenetriamine, 80-180 parts of allyl thiourea and 100-180 parts of benzoic acid. According to the concrete rust inhibitor, the corrosion of steel bars in reinforced concrete can be effectively retarded and prevented, and the damage caused by chloride ions to passivation coatings of the steel bars can be prevented or retarded.

Description

A kind of concrete corrosion resistant agent
Technical field
The present invention relates to antirust agent, particularly relate to a kind of concrete corrosion resistant agent.
Background technology
Need a large amount of use during the use in armored concrete of traditional corrosion inhibitor, and stop reinforcing bar quilt The ability of corrosion is poor.
Summary of the invention
It is an object of the invention to provide a kind of concrete corrosion resistant agent, solve in above-mentioned prior art problem Individual or multiple.
According to an aspect of the present invention, it is provided that a kind of concrete corrosion resistant agent, including sodium molybdate 1-8 part, Diethylenetriamine 300-500 part, Allyl thiourea 80-180 part, benzoic acid 100-180 part.
During production, above-mentioned whole materials are joined in agitator, and add the water that quality accounting is 30%, It is uniformly mixed.
The concrete corrosion resistant agent of the present invention can effectively slow down and stop the corrosion of reinforced concrete, Can stop or delay the chloride ion destruction to rebar passivation film.
Detailed description of the invention
Embodiment 1: include sodium molybdate 1 part, diethylenetriamine 300 parts, Allyl thiourea 80 parts, benzene 100 parts of formic acid.
Embodiment 2: include sodium molybdate 4 parts, diethylenetriamine 400 parts, Allyl thiourea 140 parts, benzene 130 parts of formic acid.
Embodiment 3: include sodium molybdate 8 parts, diethylenetriamine 500 parts, Allyl thiourea 180 parts, benzene 180 parts of formic acid.
During production, above-mentioned whole materials are joined in agitator, and add the water that quality accounting is 30%, It is uniformly mixed.
In sum, the concrete corrosion resistant agent of the present invention can effectively slow down and stop steel in armored concrete The corrosion of muscle, it is possible to stop or delay the chloride ion destruction to rebar passivation film.
The above is only one embodiment of the present invention, it is noted that skill common for this area For art personnel, without departing from the concept of the premise of the invention, it is also possible to make some similar Deformation and improvement, within these also should be regarded as protection scope of the present invention.
