Ensuring the Performance Characteristics of Intumescent Fire-retardant Compositions for Metal Structures at Liquid Hydrogen Transportation Facilities

Year: 2025

Type: article

Abstract: The problems of ensuring the performance characteristics of intumescent fire-retardant compositions for metal structures in the conditions of liquid hydrogen transportation are considered. The influence of long-term low-temperature exposure (down to -253 °C) and the risk of high-temperature fire is shown. The results of experimental studies on the modification of epoxy IFC «Termobarrier-2» with carbon nanoparticles (astralenes) at concentrations of 0,1–1,0 % vol. are presented. It was found that the introduction of 0,2 % vol. astralenes provides a maximum increase in adhesive strength by 19,6 %, and a concentration of 1,0 % vol. increases the fire retardant efficiency by 44,4 % compared to the base composition. The use of nanomodified IFC is considered for the comprehensive protection of hydrogen infrastructure facilities.
