摘要
以常见的建筑保温材料酚醛板和挤塑聚苯板为实验材料,分别借助水平垂直燃烧、氧指数对其进行阻燃性能研究。结果表明:酚醛泡沫板在水平及垂直燃烧测定时均无法被点燃,只能在火焰的作用下形成炭黑;而聚苯乙烯泡沫板在水平燃烧测试时,当点火时间为3.6s时即被点燃,9.6s后燃尽自熄;当垂直燃烧测试时,点火时间3.3s即可被点燃,6.4s后燃尽自熄。它们的氧指数测定结果为酚醛泡沫板的氧指数为41,聚苯乙烯泡沫板的氧指数为24,说明酚醛泡沫板具有比聚苯乙烯泡沫板更为优良的阻燃性能。
The flame retardant performance of phenolic foam board and polystyrene foam board was studied by means of the horizontal and vertical combustion analyzer and oxygen index instrument. The results showed that phenolic foam board could not be ignited in the horizontal and vertical combustion analyzer and it only generated carbon black under the action of the flame. The polystyrene foam board would be ignited in 3.6s by horizontal combustion test and it was burn ed completely in 9.6s. When the vertical combustion of polystyrene foam board was tested,it would be ignited in 3.3s and was burned completely in 6.4s. The oxygen index of phenolic foam board was 41, the oxygen index of polystyrene foam board was 24. Finally, the experiment showed that flame retardant performance of phenolic foam board was more excellent than that of polystyrene foam board.
