采用非等温热重分析（TG）技术，在惰性气氛和5．0、10．0、25．0 K · min-1线性升温速率条件下，考察了5种导热填料填充的双组分加成型液体硅橡胶的热降解性能，采用Flynn-Wall-Ozawa（FWO）模型对非等温动力学数据进行分析，求取并比较了各样品热降解反应的表观活化能 Ea ．结果表明：5种填料中，B N填料填充的LSR热性能最好；当BN添加量达到40 phr（每百份橡胶）时，LSR样品的热性能得到显著提高．

The thermal degradation of two-component addition liquid silicone rubber (LSR) filled with five different kinds of thermal conducting fillers are respectively investigated by means of the non-isothermal thermal gravimetric analysis method in inert atmosphere environment at linear heating rate of 5 .0 ,10 .0 and 25 .0 K .min-1 .The recorded non-isothermal kinetics data are treated by Flynn-Wall-Ozawa (FWO) model and thus the apparent activation energy Ea for the thermal degradation reactions of each kind of LSR samples is calculated and compared .The results indicate that the LSR sample filled with BN filler exhibits the best thermal stability in these five samples .When the dosage of BN filler reaches to 40phr (per hundreds of rubber ) ,the thermal stability of LSR is significantly improved .
