摘要
为了提高文物保护材料PU(一种MDI型聚氨酯)的耐光老化性能,采用紫外线吸收剂UV531、UV328和UVP对其进行改性。使用傅立叶变换红外光谱、反射光谱、光老化失重等手段表征改性材料的耐光老化性能。通过对表征结果的比较,得出了UV531改性MDI型聚氨酯比未改性MDI型聚氨酯及其它二种改性材料具有更优异的耐光老化能力,其对彩绘漆器文物样品也能起到更好的保护作用。
The UV- absorbers,UV531 ,UV328 and UVP were added into PU （an MDI polyurethane） to improve its light - fastness. FTIR,reflectance spectroscopy and light aging weight loss experiments were done to test the anti photoageing properties of the modified material. After comparative studies,it was concluded that the anti - photoageing properties of PU modified with UV531 are better than those of unmodified PU, and PU modified with UV328 and UVP. This research suggested that the modified PU with UV531 has great potential for the protection of colored lacquer relics.
