XD9露天石质文物保护剂

目的研究合成高性能树脂基露天石质文物保护剂XD9。方法用自合成的聚丙烯酸酯改性有机硅树脂,经耐水、抗盐酸、抗酸雨、抗紫外线、抗酸碱、冻融、饱和碳酸溶液浸泡、3%NaCl浸泡、户外埋藏及耐热老化等性能测试。结果对陕西茂陵博物馆汉代露天石质文物保护后达15a之久;对西安碑林博物馆露天展出明代石狮保护达9a之久。结论XD9露天石质保护剂具有黏接力强、渗透力较好、耐水、耐酸雨、抗微生物侵蚀的特性;保护层有耐水、风、沙、日光照射,抗冰冻、微生物侵蚀的作用,并具有良好的附着力和耐久性;XD9石质保护剂无色透明,抗酸、碱、盐,耐水性好,使用方便,并且该保护剂可逆。

XD9 protective agent for the stone relics in the open air

Aim To compound high performance resin matrix protective agent XD9for the stone relics in the open air.Methods Use silicone resin,which is modified by synthetic polyacrylate after the following tests: resistance against water,resistant HCl,acid rain resistance,uvioresistant,acid resistance,resistance to alkali,freeze-thaw test,dipping in saturated carbonic acid solution and 3% NaCl solution,burial outdoors,heat age resistance.Wind,rain,sand,freeze,soluble salts,sunlight,the change of temperature and anaerobic corrosion,etc.Results After all kinds of performance tests it has been used to protect the stone relics in the open air in Shaanxi Maoling Museum have lasted 15 years and the stone lions in Ming Dynasty in Xi'an Beilin Museum outdoors 9 years.Conclusion It is proved that XD9 protective agent for the stone relics in the open air has good performances including adhesives,penetrating power,resistance against water,weather fastness and antibacterial corrosion,etc.It has a good performance and little effect on the protective agent.XD9 protective agent for the stone relics is colorless and glassy.In addition the protective agent has reversibility.
