| 摘 要： | 利用氧指数仪测定了全磷阻燃剂（DMMP、DEEP、V6）、卤代磷酸酯阻燃剂（TCEP、TCPP、TDCP）及两类阻燃剂复配对硬质聚氨酯泡沫塑料(RPUF)氧指数的影响。结果表明，全磷阻燃剂的阻燃效果优于卤代磷酸酯类阻燃剂；磷卤复配阻燃效果优于单一阻燃剂；单独使用DMMP或DMMP与TCEP复配使用阻燃效果最佳，这句话跟上一句不是矛盾吗？氧指数分别为23.0 %和24.5 %。利用锥形量热仪进一步研究了7种不同硅烷匀泡剂对RPUF阻燃性能的影响。结果表明，硅烷匀泡剂AK8803在提高RPUF的点燃时间以及降低RPUF燃烧释放热危害方面，优于其他6种匀泡剂；而硅烷匀泡剂L580则在降低RPUF燃烧烟气量方面优于其他6种匀泡剂。

| Abstract: | The flame retardancy of phosphorus- and halogen-containing flame retardants for rigid polyurethane foam was investigated by means of oxygen index tester and cone calorimeter. It showed that the flame retardancy of rigid polyurethane foam based on phosphorus-containing flame retardants was better than that on halogen-containing ones. Moreover, combinations the two kinds flame retardants provided even better results. For individual flame retardant, AK8803 was the most effective in extending the ignite time and reducing the heat damage, L580 was best one for inhibiting smoke and poison gas. |
