Abstract

Steel packing tape is widely used for packaging goods of various purposes, including heavy and large ones: reinforcing materials, pipes, rolled metal. Polymer coatings and wax emulsions are applied to surface of metal packing tape to increase its corrosion resistance. This allows tape to withstand not only high air humidity, but also chemical effects of many aggressive agents. Wax emulsions affect sliding, abrasion, movability and water resistance of material. The purpose of this work is to study chemical composition and operational properties of wax emulsions steel packing tape coating. The chemical composition of wax emulsions was analyzed by infrared spectrometry. Sliding was evaluated based on the results of friction and wear tests of materials. The anticorrosion properties of wax emulsions on steel tape samples were studied under conditions of elevated temperature and humidity according to “207-3” method (State Standard GOST R 51369-99) and under exposure to neutral salt mist according to “215-1.2.1” method (State Standard GOST R 52763-2007). The analysis of the IR spectra of the wax emulsions under study allowed revealing significant differences in their composition: the IR spectra of domestic wax emulsions contain absorption bands that are typical for aromatic nitro compounds. This may indicate the presence of corrosion inhibitors in these emulsions. It has been established that the emulsion of foreign production (Sample A) has the highest wear resistance, and the domestic Sample B has the least. During the corrosion tests, the corrosion centers in the form of separate spots appeared only on samples of steel tape with foreign “A” emulsion, on the other samples there were no instances of corrosion. This confirms the supposition of the presence of corrosion inhibitors in the composition of domestically produced wax emulsions, which was made based on the results of the analysis of IR spectra.
