Amelin M. Development of epoxy nanocomposite coatings filled with metal oxides for the recovery of transport

The dissertation is about development of new, modified and filled with nano- and micro-dispersed parts, protective coatings with improved operational properties for transport recovery. The influence of the paraminoazobenzene modifier on the processes of formation of the epoxy binder are studied and the regularities of improving the adhesion, physical and mechanical and thermal-physical properties of the modified polymer matrix is determined by introducing an additive at optimum content due to the formation of a material with a uniformly distributed structure which is characterized by a significant number of chemical bonds per volume. Using the methods of mathematical statistics, the composition of the adhesion and functional layers of composites with nano- and microdispersed fillers for the formation of coatings with improved anticorrosive properties and durability is optimized. New developed materials for increasing corrosion resistance and hydroabrasive wear resistance of protective coatings are characterized by improved properties compared with known analogues. New composites and technology of their formation are implemented on the Private enterprise «Intelligent marine technologies» (Mykolaiv). As a result of bench tests of the developed protective coatings, an increase in the corrosion resistance of parts of transport in the range of 2.3...2.8 times is established, and resistance to hydroabrasive influence in alkaline aggressive environments is 1.6...1.8 times, compared with traditional protective coatings.
