Stone cultural relic reinforcing and protecting material as well as preparation method and application thereof
The invention discloses a stone cultural relic reinforcing and protecting material as well as a preparation method and application thereof. The stone cultural relic reinforcing and protecting material is prepared from an alcohol solvent and amorphous nano calcium carbonate dispersed in the alcohol solvent, the stone cultural relic reinforcing and protecting material is used for reinforcing and protecting a cultural relic base body through spontaneous conversion from amorphous nano calcium carbonate to crystalline calcium carbonate. According to the method disclosed by the invention, the material in a solution form or a powder form can be prepared through dispersion, reaction, separation or drying. The amorphous nano calcium carbonate material disclosed by the invention has relatively small nano particle size and relatively high activity and permeability, and can generate a relatively good reinforcing effect on stone cultural relics such as limestone in a short time through deposition of nano calcium carbonate and change of crystal morphology. The amorphous nano calcium carbonate and the calcium carbonate crystals spontaneously converted from the amorphous nano calcium carbonate have similar main components with limestone stone cultural relics, and have good compatibility with the limestone stone cultural relics.
本发明公开了一种石质文物加固保护材料、其制备方法和应用，由醇溶剂及分散在醇溶剂中的无定形纳米碳酸钙组成；利用该石质文物加固保护材料通过无定形纳米碳酸钙向结晶碳酸钙自发转化对文物基体进行加固保护。本发明方法通过分散、反应、分离或烘干，能制备溶液形式或粉末形式的材料。本发明无定形纳米碳酸钙材料具有较小的纳米粒径，以及较高的活性和渗透性，能在短时间内通过纳米碳酸钙的沉积以及晶体形态的变化对石灰岩等石质文物产生较好的加固作用。本发明无定形纳米碳酸钙及其自发转化而成的碳酸钙晶体与石灰岩类石质文物具有相近似主要成分，与石灰岩类石质文物兼容性好。
