Abstract

The invention provides a high-strength organic-inorganic composite cementitious material, a preparation method thereof and application of the high-strength organic-inorganic composite cementitious material in cultural relic protection. The high-strength organic-inorganic composite cementing material comprises a calcium-based inorganic material and an organic material with a polyhydroxy functional group or a polysaccharide functional group, wherein the mass ratio of the organic material to the calcium-based inorganic material is (1-10): 100; the organic-inorganic composite cementing material recognizes calcium ions through organic matter of the organic material and promotes the calcium ions to react with carbon dioxide in air to generate calcium carbonate crystals, and calcium carbonate grows in an oriented mode along the organic material with the organic material as a template to form a layered composite structure.

本发明提供一种高强度的有机无机复合胶凝材料及其制备方法和在文物保护中的应用。所述高强度的有机无机复合胶凝材料包括钙基无机材料和具有多羟基官能团或者多糖官能团的有机材料，有机材料和钙基无机材料的质量比为1‑10：100；所述有机无机复合胶凝材料通过有机材料的有机质识别钙离子并促使钙离子与空气中的二氧化碳反应产生碳酸钙的结晶体，所述碳酸钙以有机材料为模板沿着有机材料定向生长形成层状复合结构。
