摘要:
为探究湿热环境下植鞣皮革的劣化机理 ,在 20~80℃、20%~80%相对湿度范围内展开耦合老化实验 ,观察劣化模拟样历时 16d的老化进程及其性能与微观结构变化;采用扫描电子显微镜、傅里叶变换红外光谱以及色差测试、失重率分析、柔软度测试、机械性能测试、羟脯氨酸含量检测等手段 ,对劣化皮革样品进行表征 。结果表明 :温度与湿度在加速皮革劣化过程中呈现显著协同效应 。高温高湿(80℃ ,相对湿度80%)条件下皮革劣化最为剧烈 ;老化 16 d后 ,纤维网络结构崩解、原纤维形貌基本消失;红外光谱中酰胺Ⅰ带和酰胺Ⅱ带特征峰强显著减弱 ,羟脯氨酸含量降至初始值的 45.0%;抗张强度与断裂伸长率分别降至初始值的 37.9%和 7.4%。在宽范围湿热耦合作用下 ,皮革劣化呈现从化学键断裂、微观结构损伤、组分流失到宏观性能下降的变化特征 。上述结果明确了湿热耦合条件下植鞣皮革劣化进程的关键指标变化规律 ,可为皮革文物的保存环境控制、劣化状态评估及保护材料筛选提供参考依据。
