Ground tire rubber (GTR) was mechano-chemically modified with road bitumen 160/220 and subsequently treated using a microwave radiation. The combined impact of bitumen 160/220 content and microwave treatment on short-term devulcanization of GTR was studied by thermal camera, wavelength dispersive X-ray fluorescence spectrometry (WD-XRF), static headspace, and gas chromatography-mass spectrometry (SHS-GC-MS), thermogravimetric analysis combined with Fourier transform infrared spectroscopy (TGA-FTIR), oscillating disc rheometer and static mechanical properties measurements. The obtained results showed that bitumen plasticizer prevents oxidation of GTR during microwave treatment and simultaneously improves processing and thermal stability of obtained reclaimed rubber.
将废轮胎橡胶（GTR）与160/220道路沥青进行机械化学改性，随后进行微波辐射处理。通过热成像仪、波长色散X射线荧光光谱仪（WD-XRF）、静态顶空和气相色谱-质谱联用仪（SHS-GC-MS）、热重分析结合傅里叶变换红外光谱仪（TGA-FTIR）、振荡盘流变仪以及静态力学性能测量，研究了160/220沥青含量和微波处理对GTR短期脱硫的综合影响。所得结果表明，沥青增塑剂可防止GTR在微波处理过程中氧化，同时提高所得再生橡胶的加工性能和热稳定性。
