| 目的 研究低气压环境综合加速试验技术在聚氨酯涂层的低气压环境适应性评价中的加速性。方法 开展聚氨酯涂层低气压环境综合加速试验和低气压自然环境试验，分析聚氨酯涂层在两种试验环境中的老化机理、色差和光泽度变化规律，采用加速转换因子(ASF)法处理试验数据，分析低气压环境综合加速试验技术的加速性。结果 与低气压自然环境试验12个月相比，在低气压环境综合加速试验60 d内，聚氨酯涂层的老化机理、色差和光泽度变化规律基本不变。低气压环境综合加速试验的加速倍率随试验时间延长而逐渐降低，最高为24倍，最低为10倍。结论 低气压环境综合加速试验技术综合模拟了低气压自然环境的太阳辐射、气压、温度和湿度等条件，具有很好的模拟性和加速性，适用于快速评价聚氨酯涂层在低气压环境下的适应性。 |

| To study the acceleration of adaptable evaluation for comprehensive accelerated test technology in Polyurethane Coating in low pressure environment, the comprehensive accelerated test in low pressure environment and natural environment test in low pressure environment of polyurethane coating were carried out to analyze the aging mechanism, color difference and glossiness change rule of polyurethane coating in the two environmental tests, and the process of test data with the method of acceleration switchover factor (ASF) was conducted to analyze the acceleration of comprehensive accelerated test technology in low pressure environment. The aging mechanism, color difference and glossiness of polyurethane coating in comprehensive accelerated test in low pressure environment after 60 days were basically the same as those of natural environment test in low pressure after 12 months. Accelerated ratio of comprehensive accelerated test in the low pressure environment decreased as the test time prolonged, and the highest accelerated ratio was 24 times and the lowest was 10 times. The comprehensive accelerated test technology in low pressure environment comprehensively not only simulates the conditions of solar radiation, air pressure, temperature and humidity in natural environment, but also can acquire great acceleration, which is suitable for rapid adaptable evaluation of polyurethane coating in low pressure environment. |
