Reinforcing steel bar inhibitor and preparation method thereof
The invention relates to a reinforcing steel bar inhibitor. The reinforcing steel bar inhibitor is prepared from the following components: 12 parts of sodium benzoate, 3 parts of sodium silicate, 3 parts of gluconic acid, 1 part of citric acid, 3 parts of thiourea, 6 parts of dicyclohexylaminenitrite, 8 parts of coal ash, 15 parts of nitrite, 4 parts of sodium hexametaphosphate, 7 parts of diethylenetriamine, 5 parts of thiourea, 2 parts of sodium benzoate and 2 parts of urotropin. The inhibitor provided by the invention is good in adaptability to cement, so that the performances of concrete can be improved properly; the permeation of a slow release medium into concrete is slowed down; meanwhile, a layer of compact chemical adsorption membrane can be formed on the surface of a reinforcing steel bar; a corrosion medium in a concrete pore solution and oxygen are insulated from being in direct contact with the reinforcing steel bar, so that the electrochemical corrosion cannot be carried out, thereby preventing the corrosion effect to the reinforcing steel bar.
