汽车零部件金属卤素灯阳光模拟试验与户外自然曝晒的相关性研究

目的 探究汽车零部件金属卤素灯阳光模拟加速试验与户外自然曝晒的关系。方法 使用3种典型高分子透明材料分别进行阳光模拟加速试验、AIMBOX/Arizona户外曝晒和Florida户外曝晒，基于试验后样品的黄变值，比较阳光模拟试验与户外曝晒的相关性，并对阳光模拟试验与户外曝晒的加速性进行探讨。结果 阳光模拟（IP/DP箱）加速试验与AIM BOX/Arizona户外曝晒高度相关，综合加速倍率约是AIM BOX/Arizona户外曝晒的3倍。阳光模拟（IP/DP箱外）加速试验与Florida户外曝晒高度相关，综合加速倍率是Florida户外曝晒的7倍。结论 基于3种典型材料研究可知，汽车零部件阳光模拟加速试验与典型户外自然曝晒具有一定相关性。

Correlation of Sunlight Simulation Test of Metal Halide Lampfor Automotive Parts and Outdoor Exposure

The work aims to explore the relationship between the accelerated sunlight simulation test with metal halide lamps for automotive parts and outdoor exposure. Three typical polymer transparent materials were used for a sunlight simulation acceleration test, an AIM BOX/Arizona outdoor exposure test, and a Florida outdoor exposure test. Based on the yellow values of the specimens after the test, the correlation between the sunlight simulation test and outdoor exposure was compared. And the acceleration of sunlight simulation tests and outdoor exposure was explored. The sunlight simulation (IP/DP box) acceleration test was highly correlated with the outdoor exposure of AIM BOX/Arizona. Its comprehensive acceleration rate was approximately 3 times that of AIM BOX/Arizona outdoor exposure. The sunlight simulation (outside IP/DP box) acceleration test is highly correlated with the outdoor exposure of Florid. Its comprehensive acceleration rate was approximately 7 times that of Florida outdoor exposure. Based on the study of three typical materials, it can be concluded that there is a certain correlation between the sunlight simulation acceleration test of automotive parts and typical outdoor exposure.
