| 目的 找出太阳跟踪反射聚能户外加速曝晒方法的特点和价值。方法 基于几种典型的透明高分子材料试样，分别在佛罗里达典型亚热带潮湿环境自然曝晒、汽车外饰实验室氙灯加速耐候试验及亚利桑那太阳跟踪反射聚能户外加速曝晒黄变结果相关性、加速性和区分度的对比分析，来比较这几种试验方法的特点。结果 户外加速曝晒和自然曝晒的相关性高于氙灯加速试验和自然曝晒的相关性。与自然曝晒相比，户外加速曝晒的平均加速倍率及不同试样的加速倍率的相对差异明显小于氙灯加速试验。自然曝晒和户外加速曝晒的区分度也明显大于实验室氙灯加速试验。结论 户外加速曝晒方法较好地均衡了相关性、加速性、加速一致性及区分度，适合高分子材料的验证性试验。 |

| This paper aims to find the characteristics and value ofoutdoor accelerated exposure method with solar tracking reflection and concentrated energy.Based on several typical transparent polymer material samples, the characteristics of these test methods are compared by comparing the correlation, acceleration and discrimination of the yellowing results of natural exposure in Florida’s typical subtropical humid environment, xenon lamp accelerated weathering test in the automotive exterior decoration laboratory and Arizona’s solar tracking reflection shaped energy outdoor accelerated exposure. The correlation between outdoor accelerated exposure and natural exposure is higher than that between xenon lamp accelerated test and natural exposure. Compared with natural exposure, the average acceleration ratio of outdoor accelerated exposure and the relative difference of acceleration ratio of different samples are obviously smaller than that of xenon lamp accelerated test. The distinction between natural exposure and outdoor accelerated exposure is also significantly greater than that of xenon lamp accelerated test in laboratory. The outdoor accelerated exposure method has well balanced the correlation, acceleration, acceleration consistency and discrimination, and is suitable for the verification test of polymer materials. |
