摘要： 研究了锡酸盐/十溴二苯醚(DBDPO)阻燃体系与Sb2O3/DBDPO阻燃体系对聚苯乙烯(PS)的阻燃消烟作用。通过热重分析和差热分析研究了阻燃PS从室温到800 ℃的热降解过程，探讨了不同体系的阻燃机理。结果表明：锡酸盐阻燃剂体系处理的样品极限氧指数最高为27.8 %，烟密度等级最低为68.37，与未经阻燃剂处理的样品相比具有较好的阻燃消烟性能。加入Fe3+、Co2+、Ni2+、Cu2+等可改变PS的热降解过程，对PS第一阶段的降解起催化作用，并且有效地促进炭化物的生成，提高材料的阻燃消烟性能。

Abstract: The flame retardancy and Smoke Supression of the PS treated with the stannates/DBDPO additives or the systems containing the Sb2O3/DBDPO has been studied. The thermal degradation in air of PS treated with flame retardants has been studied by differential thermal analysis (DTA) and thermogravimetry (TG) from ambient temperature to 800℃. The mechanisms of the flame retardants are studied. The results shows that PS treated with the stannates additives given the highest limiting oxygen index is 27.8 and the lowest smoke density rating is 68.37, which indicate that the flame retardancy and smoke suppression of the treated PS is improved. Fe3+、Co2+、Ni2+ and Cu2+ have changed the thermal degradation course of PS and accelerated to carbide efficiently so as to enhance the flame retardancy and smoke suppression of the materials.

Key words: polystyrene, stannates, flame retardancy, degradation, thermal analysis
