摘要
根据重庆大足所处的酸雨雾环境条件,采用多种模拟加速老化试验,并结合红外光谱、接触角和形貌观察等分析手段,研究了文物贴金用传统金胶漆耐湿污染大气腐蚀的情况。结果表明:大气酸雨污染加速了水的干湿交替环境对金胶漆的影响。光照、湿度和污染大气的干湿交替环境对金胶漆都有不同程度的影响,其中污染大气的干湿交替环境对金胶漆的耐老化性能破坏最严重,最终导致了金胶漆材料的腐蚀破坏。
According to the environmental conditions of acid rain and fog in Dazu,Chongqing,the corrosion resistance of traditional gold glue paint used for gilding of cultural relics to wet polluted atmosphere was studied by a variety of simulated accelerated aging tests and combining with analytical methods such as infrared spectroscopy,contact angle,and morphology observation.Results showed that atmospheric acid rain pollution accelerated the impact of the alternating wet and dry environment of water on gold glue paint.Additionally,light,humidity and the alternating wet and dry environment of polluted atmosphere had varying degrees of influence on gold glue paint.Among them,the alternating dry and wet environment of polluted atmosphere possessed the most serious damage to the aging resistance of gold glue paint,which eventually led to the corrosion damage of gold gule paint materials.
