硅橡胶复合绝缘子（SiR）材料在电力和工业中应用广泛，废SiR具有转化为新的自然能源的潜力。采用热重分析仪在氮气气氛中研究加热速率（β）为10、20、30、40 ℃/min的SiR在50~800 ℃范围内的热解动力学。结果表明：在SiR的热解过程中，随着加热速率的增加，热重曲线的峰值向较高的温度移动，温度变化约为100 ℃。同时，采用Kissinger （KAS）法、Friedman （FR）法和Flynn-Wall-Ozawa （FWO）法3种等转化方法对SiR的非等温热解动力学进行分析。结果表明：3种等转化方法得到的活化能之差不超过10 kJ/mol，总体趋势非常相似。SiR热解的活化能范围在44.67~59.65 kJ/mol之间。

Silicone rubber composite insulators (SiR) materials are widely used in electricity and industry, and waste SiR has the potential to be transformed into new natural energy sources. Thermogravimetric analysis was conducted in a nitrogen atmosphere to study the pyrolysis kinetics of SiR heated at rates (β) of 10, 20, 30, 40 °C/min over the temperature range of 50 to 800 °C. The results showed that during the pyrolysis process of SiR, as the heating rate increases, the peak of the thermogravimetric curve shifted towards higher temperatures, with a temperature change of approximately 100 ℃. Meanwhile, the non-isothermal pyrolysis kinetics of SiR were analyzed using three conversion methods: Kissinger (KAS) method, Friedman (FR) method, and Flynn-Wall-Ozawa (FWO) method. The results showed that the difference in activation energy obtained by the three equal conversion methods did not exceed 10 kJ/mol, and the overall trend was very similar. The activation energy range of SiR pyrolysis was between 44.67~59.65 kJ/mol.
