STUDYING OF THE INFLUENCE OF SIZE CHANGEOF TITANIUM DIOXIDE (TiO2) GRAIN ON THE STRUCTUREAND PROPERTIES OF THE COATING SYSTEM EPOXY – TiO2

摘要

In onder to examine different in properties and structure of the coating Epoxy modified with tworntypes of Titanium dioxide: normal (size of grain > 40 μm) and nano-sized (7?10 nm), we have studiedrnanticorrosion ability of of Epoxy coatings modified with two types of inorganic additive in acide (H2SO4)rnsolution of 30%, 60% at the temperature 250 and 600C, and alkaline (NaOH) of 5% solution at 600C. Resultrnof EIS mesuring and SEM method show that the coat of epoxy modified with TiO2 has the protectingrnability greater than that of epoxy coat, and only small amount of nano?size particles TiO2 in the coatingrnmaterial ( 0.6% Epoxy weight) increases considerably its anticorrosion protection ability.
