The Effect of Epoxy Resin on the Properties of Encapsulated Fire Extinguishing Agent

다국어 초록 (Multilingual Abstract)

Fire extinguishing composite materials based on low-viscosity epoxy resin (EP) and containing 50 wt% of encapsulatedfire extinguishing agent (EFA) have been studied. The positive effect of the EP on the kinetics and temperature of the EFAdecapsulation was established. The EP increases the decapsulation temperature of the EFA from 130 ℃ to 155 ℃ andchanges the kinetics of the decapsulation. The epoxy matrix increases the thermal stability of the EFA more than 3.9 timescompared to that of the pure EFA. The protective effect of the EP on the storage stability of the EFA was validated. Themass loss of EP-containing EFA at 60 ℃ and 80% humidity over 96 h is 0.4%. The mass loss of pure EFA under thesame conditions is 15%. A similar effect was observed under ultraviolet radiation: the EP-containing EFA loses 0.8% atpure EFA mass of 6%. The testing of alternative polymer matrixes has been considered.
