Abstract
We consider the influence of insertion of modified aluminum-silicate microspheres (MSPs) on the Payne effect, physicomechanical, thermophysical, and fire–heat-protection characteristics of elastomer compositions on an ethylene–propylene–diene rubber base. We show that when the polyphenylene oxide layer is created on the microsphere surface, the coke formation processes are enhanced and the sample mass loss decreases, thus resulting in improvement of the characteristics of the fire–heat-protection material. Additional insertion of the C60 fullerenes into the modifying additive composition makes it possible to obtain a finely porous coke structure with a positive influence on the fire–heat-protection efficiency of the material.
