摘要
对暴露在氙灯老化光源下的高耐候性外墙涂料进行人工加速老化试验,考察外墙涂料的光泽、色差、黄变等宏观光学性能,再通过研究老化前后涂膜表面的微观分子结构的变化,研究探讨氙灯老化光源对耐候性外墙涂料老化性能的影响。
Artificial accelerated ageing test of high weatherability exterior wall coatings were carried out under xenon lamp exposure.The change of macroscopic optical property of coating has been contrastive studied,including gloss,color difference,yellow index,etc.The changes of the micro-molecular structure of the coating surface before and after aging were also studied.The influence of xenon lamp aging light source on the aging properties of exterior wall coatings has been investigated.
