STUDYING STRUCTURE AND PROPERTIES OF THE COATING NANOCOMPOSITE BASED ON THE EPOXY MODIFIED BY TITANIUM DIOXIDE (TiO2)

摘要

In onder to examine different in properties and structure of the coating Epoxy modified with two types of Titanium dioxide: normal (size of grain >40 μm) and nano-sized (7 ?10 nm), we have studied anticorrosion ability of of Epoxy coatings modified with two types of inorganic additive in acide (H2SO4) solution of 30%, 60% at the temperature 25° and 60°C, and alkaline (NaOH) of 5% solution at 60°C. Result of EIS mesuring and SEM method show that the coat of epoxy modified with TiO2 has the protecting ability greater than that of epoxy coat, and only small amount of nano ?size particles TiO2 in the coating material (0.6% Epoxy weight) increases considerably its anticorrosion protection ability.
