通过添加TiO2、SiO2纳米颗粒对一种有机硅氧烷 类渗透固结型石质文物防护剂进行改性，并通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)和紫外分光光度计等测试了改性后防护剂的性能.研究结果表明，纳米粒子在防护剂中的分散性较好，改性后的纳米复合防护剂的固结性能、耐紫外线、透水等主要性能有了明显的提高.
Nanoparticles of TiO2 and SiO2 were used to enhance the property of a kind of siloxane,which was often used for the preservation of stoneware of historical relic.The dispersion of nanoparticles was verified to be a key factor.The consolidation of the siloxane with nanoparticle, on stonew ares was also evaluated.All these main properties of the nanocomposite were impro ved in comparison with nanoparticles free siloxane,so adding nanoparticles of TiO2 and SiO2 into siloxane was an effective means to protect stoneware of historical relic.
