Kaulin V.Y. Modification of coal tar pitch by active additives to produce pitch-composite. - Manuscript. Thesis for the degree of Candidate of Technical Sciences, specialty 05.17.07 - Chemical Technology of Fuels and Lubricants, National Metallurgical Academy of Ukraine, Dnipropetrovsk, 2016. This study considered the results of theoretical and experimental research on coal tar pitch modification by active additives in order to receive a pitch composite. The thesis is devoted to the influence of active additives on the thermochemical and structural transformations coal tar pitch processes. It is established that the considered active and active complex additives intensify the structure formation processes of in coal tar pitch. The coal tar pitch modification process contributes to strengthening its structure, resulting in the improvement of its thermophysical and physic-mechanical properties as the matrix, and composite materials based on it. A new composite material, which can be attributed to the properties of materials for general technical purposes. The technological process of coal tar pitch modification by active additives in order to receive a pitch composite been developed. The presented results show that coal tar pitch is a unique product. Its chemical potential can be used more qualified by creating new composite materials on its basis. The results of studies undertaken to design a pilot plant of extrusion production of composite materials based on the modified coal tar pitch. Materials of this thesis are of use at the department of Chemical Technologies at the Donetsk National Technical University in the dissertations and master's theses preparation by students of specialty 7(8).05130105 "Chemical technology of fuel and carbon materials." Keywords: coal tar pitch, active additives, polymer, modification, composite materials, pitch composite.
