摘要:

选择本地区部分焦山石刻,从物理因素、化学因素、生物因素以及人为因素等方面,分析了引起焦山石刻风化的原因。本文以丙烯酸酯为基料,甲基丙烯酸十二氟庚酯和二氧化硅为改性剂,制备了一种成膜性好、无色透明的氟硅丙烯酸酯封护材料。通过模拟抗风化试验,研究封护材料在焦山石刻上的抗风化能力。结果表明,经封护后,能保持石质文物原貌,且具有较好的耐水、耐酸碱性和较强的抗风化能力。

Some Jiaoshan stone relics in this region were chosen to analyze the causes of weathering from the perspective of physical, chemical, biological and human factors. A fluorine-silicon acrylate protec-tive material with good film-forming and colorless transparent performance was synthesized by acrylate as basic material, dodecafluoroheptyl methacrylate and siloxane as modifiers. Based on simulating the anti-ageing experiment, weathering resistance of protective material on Jiaoshan stone relics was analyzed. The results show that it can keep original appearance of stone relics after protection treatment, and that water, acid and alkali-resistance of the material are excellent. What’s more, it is of high resistance to the weathering.
