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Ｓｂ＿２Ｏ＿３效果最显著；Ｓｂ＿２Ｏ＿３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。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 de-grees,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 re-tandant agents.Through thermodynamics calculations,abilitedies of fire retanding and catching HCl arecompared among some inorganic fire retandant agents.
