Description
Technical field
The present invention relates to corrosion inhibitor technical fields, and in particular to a kind of concrete corrosion-prevention rust-resistance agent.
Background technology
Reinforcing steel bar corrosion inhibitor mixes in concrete to prevent or slow down the additive of steel bar corrosion.Reinforcing steel bar corrosion inhibitor refers to adding
Enter in concrete or brush in concrete surface, can prevent or slow down the chemical substance of reinforcement corrosion.Some can improve concrete
Additive or outer coating protectant (such as silicon ash, impregnating with silane agent) to reinforcing bar barrier propterty are not belonging to reinforcing steel bar corrosion inhibitor scope,
Reinforcing steel bar corrosion inhibitor must be able to directly prevent or delay steel bar corrosion.Traditional corrosion inhibitor can be divided into Anodic Type and cathode type.Using
Extensive nitrite is Anodic Type corrosion inhibitor, and this kind of corrosion inhibitor has larger murder by poisoning to human body and environment, the meeting when dosage deficiency
Accelerate steel bar corrosion, there are prodigious application risk, current many developed countries have been forbidden to use.Cathode type corrosion inhibitor is such as：Phosphorus
The dosage of hydrochlorate, carbonate, aliphatic ester etc., this kind of corrosion inhibitor is often larger, and Cost of Concrete is made to improve, and inconvenience is promoted.
