Summary:Title screen
One of the ways to enhance thermal stability and reduce the flammability of polymers is the introduction of fillers with flame retardant properties. The paper studies the effect of natural zeolites of the Sakhaptinsk and Shivyrtuysk deposits on the thermal stability and flame retardancy of epoxy composites. The thermal stability of epoxy composites was characterized by thermogravimetric analysis in oxidizing (air) and inert (argon) atmospheres. The parameters of thermo-oxidative degradation and thermal degradation of the samples with a filler concentration of 0, 1, 5, and 10 wt% were studied. Flame retardancy of epoxy composites filled with zeolite was evaluated using the limiting oxygen index. The limiting oxygen index increases with increasing concentration of natural zeolites in the epoxy matrix. The study revealed some differences in the first and second stages of heating the epoxy composites depending on zeolite type and did not reveal significant difference in the thermal behavior of the epoxy composites in the third stage of the heating. Thermal stability and flame retardant properties are more dependent on the zeolite content in the epoxy matrix than zeolite type.
