Elastomeric fire and heat-protective materials containing zirconium dioxide

Elastomeric fire-protective materials are widely used to protect special-propose structure in rocket, aviation and marine equipment. Important parameters of such materials are density and thermal conductivity. The reduction of these indicators while maintaining the rest of the set of materials properties is a complex and multifactorial task. A promising direction of its solution is the use of microspheres. The work shows that it is possible to increase the fire protection efficiency of elastomeric compositions, which contain transition metal oxides, with zirconium dioxide as an example. The effect of the introduction of zirconium dioxide in the form of a microdisperse powder, microspheres, and zirconium-aluminosilicate microfibers on the physical and mechanical, thermophysical, and fire protective properties of elastomeric compositions based on ethylene propylenediene rubber has also been considered.
