摘　　要：国内外瓷器修复的基本流程没有很大差异,但是西方国家生产的修复专用材料品种较丰富,值得国内修复界吸收与应用。为此,本研究着重对Hxtal NYL-1、Golden Porcelain Restoration Glaze、Golden Polymer Varnish with UVLS三款瓷器修复专用产品开展分析研究。测试结果显示,在国内外5类环氧树脂中,Hxtal NYL-1的拉伸强度最低,断裂伸长率最高。Hxtal NYL-1在波长365nm的紫外线照射78d后,其色差变化最平稳。紫外可见光谱数据显示Golden Glaze仅吸收一定的中波紫外线UVB,Golden Varnish对长波紫外线UVA和中波紫外线UVB都具有吸收能力。波长365nm紫外老化实验可证明Golden Glaze和Golden Varnish都具备较好的光稳定性。而在254nm紫外老化环境下,Golden Varnish表现出更佳的抗紫外性能。此外,围绕瓷器修复实例,对这些产品的在修复中的使用方法进行了简要梳理。There is no significant difference in the general practice of porcelain restoration in China and other countries.However,there are a wider variety of commercial products specially designed for porcelain restoration in western countries.Many of those products are quite worthy of being introduced into China.In this study,we tested and studied three imported products:Hxtal NYL-1,Golden Porcelain Restoration Glaze and Golden Polymer Varnish with UVLS.Tensile test results show that Hxtal NYL-1 has the highest elongation at breakage and the lowest tensile strength among five epoxy formulations.After 78-day exposure to UV light at 365 nm,the color of Hxtal NYL-1 varies the least among three epoxy formulations.According to the UV-Vis spectra,Golden Glaze only absorbs UVB,and Golden Varnish absorbs both UVB and UVA.The results of a 7-day UV light aging experiment show that neither Golden Glaze nor Golden Varnish becomes yellow after being exposed to UV light at 365 nm,but Golden Varnish is much less prone to yellowing than Golden Glaze at 254 nm.In addition,based on some practical cases,the usage of these products in porcelain restoration is also briefly introduced in this paper.
