摘　　要：本研究探讨了以钙源、磷酸盐源、胶原蛋白矿化溶液浸泡—气体扩散多循环法加固古代骨骼材料的工艺方法,并利用超景深显微镜、傅里叶转换红外光谱(FT-IR)、X射线衍射仪、扫描电镜和色度分析法、抗压强度试验等方法研究了保护效果。结果表明,利用该工艺处理后的生物磷灰石骨骼具有加固材料成分和骨质本体一致,原位合成且深入到骨质内部等特点,克服了有机聚合物及其他矿物材料简单物理充填的一些弊端,且处理过程简单、效率高、外观改变小,能满足对脆弱骨质文物、人骨及其他动物骨骼的加固保护需求。This study discusses the multi-cycle method for reinforcing ancient bone materials by soaking in sources of calcium ions and phosphate ions and collagen mineralizing solution-gas diffusion,and investigated the conservation effect using ultra-depth of field microscopy,Fourier transform infrared spectrometry(FT-IR),X-ray diffraction(XRD),scanning electron microscopy(SEM),color analysis and compressive strength testing.The results show that,for the biological apatite bone treated by this method,the reinforcement material has the same composition as that of the bone itself and features in-situ synthesis and deep penetration into the bone,overcoming some disadvantages of simple physical filling with organic polymers and other mineral materials.The method boasts a simple treatment process,high efficiency and small changes in appearance,thus meeting the requirements for the reinforcement of fragile bone cultural relics as well as human and animal bones.
