METHOD FOR THE SYNTHESIS OF POLYMER COMPOSITE MATERIAL FORMULATION FOR THE PRODUCTION OF OIL STORAGE VESSEL WITH SUBSEQUENT RECYCLING AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC C08L69/00 B01J8/00 

FIELD: chemical industry.

SUBSTANCE: invention relates to chemical industry. A method for the synthesis of polymer composite material (PCM) for manufacturing of oil storage vessel (OSV) is described, which includes preparation of composition formulation on the basis of polycarbonate with addition of fillers, making pellets and PCM for physical and mechanical tests and further utilization of PCM via pyrolysis, a composition on the basis of polycarbonate with the following fillers is used as a formulation, mass %: ground carbon, glass or basalt fiber 2.0-60.0, wood flour 5.0-15.0, carbon black 2.0-15.0, carbon nanotubes 0.01-1.0, fine powder of aluminum/magnesium metal 0-2.0, catalysts - transition metal oxides 0.1-2.0, dispersant 0.1-1.0, UV-stabilizer of not more than 1.5 and thermal stabilizer of not more than 1. 0, polycarbonate - the rest, a mixture of paraffin waxes, a mixture of paraffin and montan waxes, and meta-cresol may be used as a dispersant, which then may serve as different variants of compositions of PCM milled pellets with a mass of m_lpp with different compositions and values of specific surfaces for the laboratory pyrolysis plant (LPP), where specific surfaces are determined under condition of pellet surface area ratio equality with its mass, which is equal to the similar ratio of a particle of milled material from OSV in full-size pyrolysis plant (FPP), ratio of pyrolysis material residence time intervals, m_lpp mass is chosen under the condition of equality of time of heat supply for pyrolysis reaction maintenance and providing compensation of heat losses in LPP, FPP at corresponding heat fluxes of pyrolysis chamber heaters for LPP and FPP, each PCM variant is placed in LPP and pyrolysis is performed, steam-gas mixture is supplied to afterburning unit, and solid pyrolysis residue is supplied to a separate container, after which the quantitative characteristics of toxic substances for each PCM variant shall be determined and databases for flue gases, solid residue of pyrolysis shall be compiled, regression dependencies of quantitative characteristics of each selected toxic substance for each PCM variant sample are drawn on the basis of obtained databases, and the most suitable formulation of PCM composition, degree of crushing, pyrolysis chamber temperature, air feed rate to the afterburning unit ejector are determined.

EFFECT: invention obtains composite materials depending on their properties.
