摘    要：通过氧指数测定表明,软PVC塑料添加无机阻燃剂后,阻燃性有不同程度提高,以加Sb₂O₃效果最显著;Sb₂O₃与其它无机阻燃剂复配后可出现正的或负的协同指数,通过热力学计算,比较了几种无机阻燃剂的阻燃能力和捕捉氯化氢气体的能力。

Abstract: Through determining oxygen indexes on conditions of adding inorganic fire retandant a-gents in soft PVC,experiments have proved that their oxygen indexes increase to some degrees, that fire retandant effects are best on condition of adding Sb₂O₃ and that plus or minusco-operative indexes arise from adding Sb₂O₃ combined with some kinds of inorganic fire retandant agents.Through thermodynamics calculations,abilitedies of fire retanding and catching HCl arecompared among some inorganic fire retandant agents.
