摘要

为得到环氧树脂在SF

混合气体下的热分解机理以及主要失重区间的特征分解组分判断标准

采用同步热分析仪与气相色谱质谱仪联用的方法研究了环氧树脂在SF

气氛下的热分解特性

检测了特征分解组分体积分数

并得到了其随温度变化规律

提出了判断环氧树脂表面发生局部过热性故障的方法。TG曲线表明:环氧树脂的主要失重区间并不受实验气体种类的影响

分解区间为330～470℃。DSC曲线表明:环氧树脂在SF

氛围下的分解是一个复杂的化学过程;随着混合气体中N

比例的增加

体系的热稳定性下降

的分解加剧。选择CO

、SO

、H

S、SOF

、CF

作为特征组分进行检测。环氧树脂存在条件下

不同SF

比例混合气体的特征组分产气速率和起始体积分数不同

产气温度相同。选择H

S、CF

作为判断环氧树脂表面POF温度的特征组分并建立了数学模型。

Abstract

The purpose of this paper is to obtain the thermal decomposition mechanism of epoxy resin in SF

mixed gas and the criterion for determining the characteristic decomposition component of the main weight loss interval.Therefore

the thermal decomposition characteristics of epoxy resin in SF

atmosphere were studied by means of synchronous thermal analyzer and gas chromatography mass spectrometer.The concentration of the characteristic decomposition component was detected and a method for judging the local overheating failure of the epoxy resin surface was propose

d.The TG curve indicates that the main weight loss interval of the epoxy resin is not affected by the type of experimental gas

and the decomposition interval is 330℃～470℃.The DSC curve indicates that the decomposition of epoxy resin in SF

atmosphere is a complex chemical process.As the proportion of N

in the mixed gas increases

the thermal stability of the system decreases

and the decomposition of SF

is intensified.CO

SOF

and CF

were selected as characteristic components for detection.Under the condition of epoxy resin

the gas production rate and initial concentration of the characteristic components of different SF

ratio mixed gases are different

and the gas production temperature is the same.H

S and CF

were selected as the characteristic components for determining the POF temperature of epoxy resin surface

and a mathematical model was established.
