Sapronov O. Scientific principles of directional control of structure formation, physical-mechanical and operational properties of epoxy composite coatings for protection of technological equipment of water transport

For the first time scientific principles of formation of modified matrices for protective coatings of ship equipment, which take into account the connection between the critical content of synthetic modifiers in the epoxy oligomer ED-20, structure and properties, which allowed to increase the adhesive strength by 1.7 times, the cohesive strength by 2.0 times of the applied coatings of functional purpose. It has been shown that the use of the modifier 1,4-bis (n,n-diethyldiothiocarbamate)-benzene, which contains molecules with active nitrogen atoms, provides their interaction with additional electrons of the atoms of the side groups of the epoxy oligomer. In this case, the cationic mechanism of interphase interaction was observed, which allows to adjust the crosslinking density of the system «epoxy oligomer ED-20 – modifier», as a result of which the properties of the materials are substantially improved. This, in turn, enables the formation of new functional composite materials for use in many industries. Thus, the results of the work were implemented at: PE "Engineering Bureau" "Corvette", LLC "Kherson Shipbuilding Enterprise" (Kherson); LLC OSP Corporation VATRA (Ternopil); to the company LECH-POL DYSTRYBUCJA (Poland).
