The invention discloses a composite reinforcement rust-resistant agent. The composite reinforcement rust-resistant agent is characterized by being prepared by uniformly mixing nitrite and ethanolamine in a mass ratio of (5-15):1, and purities of the nitrite and the ethanolamine are more than or equal to 99 percent. The composite reinforcement rust-resistant agent has the advantages of performing repairing, forming a compact passive film on an anode to stop the corrosion reaction of the anode, acting on a cathode and forming an insoluble film on a cathode to stop the corrosion reaction of the cathode. The composite reinforcement rust-resistant agent has a relatively good rust-resistant effect on reinforcing steel bars and has a relatively low cost.
Description
technical field [0001] The invention relates to a steel bar rust inhibitor used for reinforced concrete structures, in particular to a composite steel bar rust inhibitor and application thereof. Background technique [0002] Reinforced concrete structures are the most widely used structural materials in civil engineering today, but the presence of chloride ions can cause the steel to rust and the concrete to crack. Chloride ions in reinforced concrete structures mainly enter through two ways: one is from concrete raw materials, such as mixing water, sea sand, deicing salt, salt spray, and chlorine salt admixtures, etc., and the other is from the use environment, such as bridges and docks in the marine environment, etc. At present, there are many kinds of rust inhibitors for steel bars on the market, but most of them are anodic or cathodic rust inhibitors, which not only have a single effect, but also are relatively expensive. Contents of the invention [0003] The techni...
