EPOXY-TITANOXIDE COMPOSITES AND PROTECTIVE COATINGS BASED ON THEM
In this work, using the sol-gel method, glassy epoxy-titania composites and coatings of amine curing containing 1 mass % of metal corrosion inhibitor 1,2,3-benzotriazole were obtained. It was established, that when introducing into the composites 0.5 - 10 mass. % TiO2 decreases the glass transition temperature of the epoxy polymer matrix. The use of 1,2,3-benzotriazole in the initial composition increases the protective properties of the epoxy-titania coating on the surface of the aluminum alloy D16: the anticorrosion resistance of the substrate increases by 2 orders and the effectiveness of anticorrosion protection reaches 93 %. The method of obtaining titania composites without preliminary formation of filler particles allows to obtain coatings with higher protective properties.
