ENHANCING THERMAL STABILITY OF POLYETHYLENE COMPOSITES THROUGH ORGANO-INORGANIC MODIFICATION

Abstract

This article presents the results of research on obtaining organo-inorganic composite materials based on polyethylene (PE) and increasing their thermal stability. During the work, components such as ammonium dihydrogen phosphate, carbamide, sodium metasilicate, magnesium and calcium oxides, and melamine were used. The synthesized viscous substance was processed in a drying oven at a given temperature and time, and maleic anhydride and low molecular weight maleinized polyethylene were used as modifiers. The thermal properties of the obtained samples were studied, and it was shown that the modifiers increase the thermal decomposition temperature in the PE matrix and improve the heat resistance of the material.
