The results of a study on the thermal stability and fire-retardant efficiency of epoxy intumescent fire-retardant compositions modified with carbon nanostructures (astralenes) at a concentration of 0.2 vol.% before and after cryogenic exposure are presented. Thermogravimetric analysis revealed a 90% increase in coke residue yield at 800 °C for the modified composition compared to the unmodified one. Fire tests under hydrocarbon flame conditions showed an 11.1% increase in the time to heat the steel plate to 500 °C for the modified composition and 28.6% after cryogenic exposure. The obtained data indicate the promise of using nanomodified coatings to improve the safety of technological processes at oil and gas facilities at risk of accidental cryogenic liquid spills followed by fire.
