This paper deals with the thermal stability and decomposition behavior of brominated butyl rubber‐based damping material (BRP). The raw materials, butyl rubber matrix (IIR) and brominated phenolic resin (PF), were also investigated as control. IIR shows one decomposition stage, while PF shows four weight loss stages. Flynn‐Wall‐Ozawa calculation indicates that BRP has thermal stability between IIR and PF. Thermogravimetric analysis–Fourier transform infrared (TGA‐FTIR) and pyrolysis–gas chromatography/mass spectrometry (GC/MS) were used to investigate the volatile products under nitrogen atmosphere. As expected, BRP shows combined thermal decomposition behavior of both IIR and PF. The degradation mechanism of BRP was proposed, which is not significantly influenced by the incorporation of PF. The application stability of BRP is worth to be noticed since the post‐cure effect, that is, the free radicals remained from vulcanization would cause additional cross‐linking when stored at 80°C to 120°C.

溴化丁基橡胶基阻尼材料的热降解和热解研究

本文探讨了溴化丁基橡胶基阻尼材料（BRP）的热稳定性和分解行为。还研究了丁基橡胶基质（IIR）和溴化酚醛树脂（PF）的原料作为对照。IIR显示一个分解阶段，而PF显示四个减肥阶段。Flynn-Wall-Ozawa计算表明BRP在IIR和PF之间具有热稳定性。使用热重分析-傅立叶变换红外（TGA-FTIR）和热解-气相色谱/质谱（GC / MS）来研究氮气氛下的挥发性产物。正如预期的那样，BRP显示了IIR和PF的综合热分解行为。提出了BRP的降解机理，其不受PF掺入的显着影响。
