Abstract :
Radiation effects on fire retardant properties of polychloroprene containing flame retardant additives were investigated. Ammonium polyphosphate, magnesium dihydrate, and antimony trioxide were selected as flame retardants. The limited oxygen index (LOI) and oxidative induction time (OIT) measurement were carried out as flame resistance tests for radiation degradation. The values of LOI increased with an increasing radiation dose due to the synergy effects between fire retardant and chlorine decomposed from CR. The values of DOT decreased with an increasing radiation dose because of dehydrochlorination and oxidation. Among the fire retardants, antimony trioxide showed the best radiation resistance and fire retardant characteristics.
