Nano calcium phosphate oligomer for reinforcing cultural relics as well as preparation method and application of nano calcium phosphate oligomer
The invention relates to a nano calcium phosphate oligomer for cultural relic reinforcement and a preparation method and application thereof, the nano calcium phosphate oligomer can be drawn by preparing an ethanol solution of calcium chloride, then adding arginine, finally adding triethylamine, adding phosphoric acid into the mixture and stirring for 12-24 hours, and the synthesis method is simple and easy to operate. More importantly, when the nano calcium phosphate oligomer synthesized by the method is applied to cultural relic reinforcement, no additional calcium source needs to be provided, and no requirement on whether a reinforcement object contains the calcium source exists. After the nano calcium phosphate oligomer is applied to ancient murals and stone cultural relics, the nano calcium phosphate oligomer prepared by the preparation method disclosed by the invention has good permeability and is converted into mutually linked hydroxyapatite with poor crystallinity within 48-60 hours.
本发明涉及一种用于文物加固的纳米磷酸钙低聚物及其制备方法和应用，将配置氯化钙的乙醇溶液，而后加入精氨酸，最后加入三乙胺向上述混合物中加入磷酸并搅拌12‑24h即可画的纳米磷酸钙低聚物，合成方法简单、易于操作。更重要的是，该方法合成的纳米磷酸钙低聚物应用于文物加固无需提供额外钙源，对加固对象是否含有钙源亦没有要求。施加于古代壁画和石质文物后发现，本发明制备的纳米磷酸钙低聚物在二者的具有良好渗透性且在48‑60h内转变为相互联接的结晶性较差的羟基磷灰石。
