Ground tire rubber (GTR) was processed using an auto-thermal extrusion as a prerequisite to green reclaiming of waste rubbers. The reclaimed GTR underwent a series of tests: thermogravimetric analysis combined with Fourier-transform infrared spectroscopy (TGA-FTIR), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and static headspace and gas chromatography-mass spectrometry (SHS-GC-MS) in order to evaluate the impact of barrel heating conditions (with/without external barrel heating) on the reclaiming process of GTR. Moreover, samples were cured to assess the impact of reclaiming heating conditions on curing characteristics and physico-mechanical properties. Detailed analysis of the results indicated that the application of auto-thermal extrusion is a promising approach for the sustainable development of reclaiming technologies.
为了实现废橡胶的绿色再生，首先采用自热挤出工艺对磨碎轮胎橡胶（GTR）进行处理。对再生后的GTR进行了一系列测试：热重分析结合傅里叶变换红外光谱（TGA-FTIR）、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）以及静态顶空和气相色谱-质谱联用（SHS-GC-MS），以评估料筒加热条件（有/无外部料筒加热）对GTR再生过程的影响。此外，对样品进行硫化以评估再生加热条件对硫化特性和物理机械性能的影响。对结果的详细分析表明，自热挤出工艺的应用是再生技术可持续发展的一种有前景的方法。
