Pyrolysis Gaseous Product Release of Bisphenol A Epoxy Resin in Air Atmosphere

为更好的实现气体组分分析法在中压开关柜局部放电检测这一领域的应用，文章对二氧化硅填料双酚A缩水甘油醚/乙二胺环氧树脂(DGEBA/EDA)进行热解气态产物释放规律研究。得出以下结论：二氧化硅填料双酚A缩水甘油醚/乙二胺环氧树脂(DGEBA/EDA)在空气氛围中200℃~800℃热解温度下仅有一个失重阶段为300℃~500℃，最大失重率为33.93%，生成的气态产物种类较多，主要包括氢气、一氧化碳、二氧化碳、烷烃、烯烃、炔烃、酮、醇、脂、醛、卤代烃、苯系物、杂环芳烃、链状及环状硅氧化合物，且各物质浓度变化规律较为复杂，整体上总烃和非甲烷总烃浓度呈先增大后趋于饱和的趋势。在200℃~300℃时，总烃浓度为11543.35~16544.13 ppm，非甲烷总烃浓度为11539.42~16526.97 ppm。
In this study, the pyrolysis gaseous product release of silica filler bisphenol A glycidyl ether/ ethylene diamine epoxy (DGEBA/EDA) were investigated. The following conclusions are drawn: DGEBA/EDA with silica filler bisphenol-a glycyl ether/ethylenediamine epoxy resin (DGEBA/EDA) were pyrolyzed at 200？C to 800？C in air, and only one weight loss stage was 300？C to 500？C, with the maximum weight loss rate of 33.93%, and various gaseous products were generated. It mainly includes hydrogen, carbon monoxide, carbon dioxide, alkanes, alkenes, alkynes, ketones, alcohols, aldehydes, halogenated hydrocarbons, benzene series, heterocyclic aromatic hydrocarbons, chain and cyclic silicoxanes, and the variation rule of the concentration of each substance is relatively complex. On the whole, the concentration of total hydrocarbons and non-methane total hydrocarbons increases first and then tends to saturation. At 200？C to 300？C, the total hydrocarbon concentration is 11543.35 ppm to 16544.13 ppm, and the total non-methane hydrocarbon concentration is 11539.42 ppm to 16526.97 ppm.
