摘要
采用GC/MS联用技术对复合阻燃装饰板常温和高温状态下的气体释放物成分进行定性和定量的分析。检测结果显示,在封箱实验期间,复合阻燃装饰板常温下释放的9种主要气体浓度没有超过GJB11.3—91标准容许浓度;高温下材料热解的气体释放物主要有35种,采用动物急性吸入试验对该材料进行高温热解物毒性检测,其动物急性吸入半数致死浓度LC50为180.8 g/m3,该材料为低等毒性材料。
Qualitative and quantitative analysis of substances released from composite fire-retardant decorative panels at room temperature and decomposed products of the material at high temperature was made by using GC / MS technique. There were 9kinds of air composition at room temperature and 35 kinds of decomposed products at high temperature from composite fire-retardant decorative panels. During the material was sealed in a box,the concentration of released products at room temperature did not surpass the permissible concentration for air components in the chambers of ships. And the median lethal concentration of acute inhalation of this material was 180. 8 g / m^3,belonged to low toxicity material.
