Flame Retardantion Effect of Antimony Oxide (Sb2O3)

초록

Antimony oxide is generally used as flame retarding assistant that produces a synergy effect when used with halogen type flame retardants. Also, many parts of its mechanism have already been verified, and in PVC, because halogen exists with the high molecules, it has been designated as a flame retardant. In this paper’s experiment, 0, 3, and 6phr of antimony oxide were put in the PVC and the oxygen index examined, in order to verify the synergy effect of antimony oxide. As can be seen from the experiment results, antimonyoxide can be confirmed to have a synergy effect of flame retardation in the presence of halogen, but when the input goes over a certain volume its effect shows a tendency to become small or reduced. This has been verified in the research on polyurethane and other high molecular materials.
