| titleOfInvention | Concrete rust inhibitor |
| abstract | The invention discloses a concrete rust inhibitor, which belongs to the field of building materials. The concrete rust inhibitor is in mass percentage, and is composed of the following components: 30-45% of nitrite, 30-45% of benzotriazole, 3-5% of tetramethylolphosphorus sulfate, polycarboxylic acid Water reducing agent 5-10%, air-entraining agent 0.02-0.05%, pentasodium phosphate 2-6%, and the balance is sodium monofluorophosphate. The preparation method of the rust inhibitor comprises the following steps: mixing sodium nitrite, benzotriazole and water, heating to 25-35° C., adding an air-entraining agent and pentasodium phosphate, stirring evenly and maintaining the temperature for 1-3 hours, and cooling to room temperature , adding tetrahydroxymethyl phosphorous sulfate, polycarboxylate water reducing agent, sodium monofluorophosphate, stirring and dissolving, and placing the solution for 15-40min to obtain a concrete rust inhibitor. The concrete rust inhibitor prepared by the invention can effectively improve the workability of concrete, slow down slump loss, enhance the effect of rust inhibition performance, and has a long corrosion inhibition duration, and is suitable for use in coastal ports, salt fields and saline soil areas. |
