摘　　要：采用红外光谱、气质联用及光谱反射技术,对涂料经不同人工气候加速老化试验后的老化状况进行了分析。结果表明通过红外光谱对涂料关键成分官能团特征峰面积比变化、气质联用仪对成膜助剂等的含量变化,以及紫外/可见/近红外分光光度计对涂料反射光谱特征减损情况表征等可以评估涂料的老化状况。The aging status of coating after different artificial accelerated climate was studied by infrared spectrum,GC-MS and spectral reflection technology.The results show that with the peak area ratio of key component functional groups characterized by infrared spectrum,the content of film-forming aids characterized by GC-MS,and the reduction of reflection spectrum characterized by ultraviolet/visible/near-infrared spectrophotometer,the aging status of coating can be evaluated.
