Annotation:

A film-forming inhibited oil composition (PINS) based on solid hydrocarbons with high protective properties has been developed. To determine the protective properties of PINS films, direct corrosion test methods and indirect methods were used: capacitive-ohmic, potentiodynamic, and determination of the corrosion rate by the method of polarization resistance. It is shown that with the introduction of lignite wax (montan wax) and phenol-formaldehyde resin in the concentration of 20 % by weight on the active substance as a component of the PINS, the physicomechanical properties of the film, the stability of the dispersion and the protective properties of the coating increase. It has been established that PINS compositions containing solid hydrocarbons possess high protective properties in mineralized media, which will allow to use them not only as a traditional means of protecting motor vehicles, but also as a means of anticorrosive protection of oilfield equipment.
