摘　　要：目的筛选出包装纸板在试验箱中开展耐光色牢度试验的5个影响因素值,并验证方法的稳定性。方法用配备了滤光器氙弧灯的试验箱模拟日光中紫外区域的光谱能量分布,调整曝晒条件模拟包装纸板及制品日常使用环境,通过响应面分析法对曝晒因素进行分析,并采用色差计量化评定试样印刷油墨的色差值耐光色牢度。结果优化的试验箱曝晒条件,黑板温度为(65±1.0)℃,空气温度为(45±1.0)℃,空气相对湿度为(50.0±2.0)%,光辐照波长为340 nm,光辐照度为0.30 W/m^2,光辐照时间为42 h。通过色差计测定人工曝晒后样品印刷油墨色差ΔE^*ab。结论验证试验表明,该方法测试结果具有可靠性及稳定性,为进一步规范包装纸板及其制品产品质量监管提供分析测试技术支撑。The work aims to screen out five influencing factors of packaging paperboard's light-fastness test in the test chamber and verify the method stability.The test chamber equipped with a filter xenon arc light was used to simulate the spectral energy distribution in the ultraviolet region of the sunlight.The exposure conditions were adjusted to simulate the daily use environment of packaging paperboard and its products.The exposure factors were analyzed by response surface analysis,and the chromatic aberration light fastness of the printing ink of the sample was evaluated by color difference meter.The optimized exposure conditions of test chamber were(65±1.0)℃ blackboard temperature,(45±1.0)℃ air temperature,(50.0±2.0)% air relative humidity,340 nm light wavelength,0.30 W/m^2 light irradiance and 42 h exposure time.The printing ink chromatic aberration ΔE^*ab of artificially exposed samples was measured by the color difference meter.The validation test shows that the proposed method is reliable and stable,which provides analytical and testing technical support for further standardizing the quality supervision of packaging paperboard and its products.
