| 摘 要： | 采用程序升温的热解反应器对酚醛树脂层压板的真空热解规律进行研究,着重考查不同热解终温对热解产物产率和热解油组成的影响,同时利用元素分析、工业分析、热重分析、GC-MS分析对层压板原料及产物油进行分析。研究结果表明:酚醛树脂层压板裂解可获得产率分别为50.25%～54.58%,33.00%～41.00%和8.75%～12.95%的液体、固体和气体,其产物油的成分主要为酚类、磷酸芳基酯类、脂肪酸酯类、腈类等物质;随着热解终温的升高,固体产率逐渐下降,液体产率在650℃有1个峰值,而气体产率则呈上升趋势,并且双酚F、双酚A、长链脂肪酸酯、磷酸三芳基酯等相对分子质量较大的物质含量逐渐降低,而苯酚、甲酚、二甲酚、对异丙基苯酚等相对分子质量较小的物质含量逐渐增大;样品有3个主要的质量损失台阶(在190～320,320～390和390～510℃),热质量损失率分别为9%,20%和31%。
