Development and Research of Preservation Liquids Based on Salts of Natural Petroleum Acids and Nitro Compounds

Atmospheric corrosion of metals is caused by the effects of the environment, particularly humid air. The main factors influencing atmospheric corrosion are humidity (increased humidity accelerates the corrosion process), atmospheric pollutants (gas, dust, etc.), temperature (increased temperature contributes to an increase in the corrosion rate), and some other factors. Atmospheric corrosion can be dry (at low humidity and leads to surface oxidation of the metal) and wet (at high humidity with the formation of a thin layer of water on the metal surface). Atmospheric corrosion can occur by both chemical and electrochemical mechanisms. Various methods are used to protect against atmospheric corrosion, such as the use of anti-corrosion coatings, the application of special oils and varnishes, and the use of corrosion-resistant materials. An effective method of protection against atmospheric corrosion is the use of preservation liquids. In this study, we developed and tested new preservation fluids based on nitro compounds, amidoamines, and salts of natural petroleum acids. The studies were conducted on steel plates in two phases with varying inhibitor concentrations.

The results demonstrate that preservation fluids obtained in the presence of the synthesized inhibitor, nitro compound, and liquid rubber exhibit superior protection of metals from atmospheric corrosion.
