Obtaining corrosion inhibitors containing synergistic nanoadditives. Nanotechnologies in construction

Introduction. Construction materials, products and structures, and primarily their surfaces, during long-term operation have been destroying mainly as a result of two types of impact: corrosive, associated with the influence of an external, aggressive environment on the material, and erosive, caused by mechanical action. An effective and widely used means of protection against corrosion is the use of inhibitors The search for effective methods of anticorrosion protection of metals and alloys is due to the great damage caused by corrosion, not only in technological or economic terms. No less dangerous is the deterioration of the ecological situation caused by the ingress of corrosion products or toxic reagents into the environment. The leading place among corrosion inhibitors is occupied by heterocyclic compounds, namely, nitrogen-containing compounds, in particular imidazoline derivatives. Methods and materials. We synthesized 2-amylidenehydrazinoimidazolinone-4n aminoguanidine, on the basis of which we obtained anticorrosion compositions with the addition of nanoadditives - derivatives of unsymmetrical triazines. Results. The synthesized anticorrosive compositions were tested by electrochemical and gravimetric methods in acidic and model environments. Conclusion. The obtained compounds have a protective ability, and the results indicate the promising use of compositions with nanoadditives - derivatives of 1,2,4-aminotriazines as corrosion inhibitors.
