摘　　要：对建筑外墙涂料在自然曝晒场进行自然曝晒试验,并同时在实验室中进行人工加速老化试验,通过考察涂层光学性能随老化时间的变化规律,统计分析自然气候曝晒试验和人工加速老化试验的数据结果,研究人工加速老化试验模拟自然气候曝晒试验的相关性,探讨涂料使用寿命的推算.The natural outdoor exposure test of building exterior wall coatings was carried out in the natural climate exposure field,whilst the artificial accelerated aging test was carried out in the laboratory.By investigating the change of optical properties of coatings with aging time,the data collected from natural climate exposure test and artificial accelerated aging test were statistically analyzed,and the correlation between simulated artificial accelerated aging test and natural climate exposure test was studied.The calculation of service life of coatings was discussed.

关 键 词：建筑外墙涂料 自然曝晒 人工加速老化 相关性
