Protecting iron objects from the negative effects of the environment is one of the main problems faced by scientists involved in the preservation of cultural heritage. The purpose of this article is to study the properties of protective coatings based on an inhibited composition of petroleum microcrystalline and polyethylene oxidized waxes formed from hot solutions to ensure the formation of "self-assembled" protective layers through a spontaneous self-organization process. These compositions can be used for long-term corrosion protection of ethnographic objects and archaeological finds after stabilizing treatment. The use of inexpensive and available domestic reagents, including oil-soluble corrosion inhibitors, makes it possible to create reliable conservation waxes for the protection of historical iron objects. It has been experimentally shown that the obtained compositions of conservation waxes are suitable for use for both ethnographic and archaeological artifacts. It was found that the protective effectiveness of Renaissance Wax on St3, both with the “cold” application method and after the dried coating has been melted, is unsatisfactory under the experimental conditions in the salt fog chamber. In the course of research, it was found that the anti-corrosion effect of conservation waxes on domestic reagents can be significantly improved by adding oil-soluble corrosion inhibitors based on neutral calcium sulfonates K-31 and NSSK-30 The effectiveness of the anti-corrosion action of protective compositions depends on the method of applying the composition and increases significantly when the wax composition is melted. The current study can be used as a basis for the development of the promising domestic protective wax coatings in order to increase the effectiveness of the protection of archaeological and ethnographic iron objects to replace the imported Renaissance Wax.
