Calcium carbonate oligomer synergistic APTS-POSS reinforced zwitterionic polymer material, and preparation method and application thereof
The invention discloses a calcium carbonate oligomer synergistic APTS-POSS reinforced zwitterionic polymer material and a preparation method and application thereof.The preparation method includes the steps that methacryloyloxyethyl phosphorylcholine and hydroxyethyl methylacrylate serve as reaction monomers to be subjected to a free radical polymerization reaction, a reaction product is purified and dried and dissolved in an organic solvent, and a zwitterionic polymer solution is obtained; the preparation method comprises the following steps: dissolving gamma-glycidoxysilylpropyl sesquioxane and 3-aminopropyltriethoxysilane in an organic solvent, and carrying out a heating reaction so as to obtain an APTS-POSS solution; a calcium carbonate oligomer solution, the zwitterionic polymer solution and the APTS-POSS solution are blended, a blended solution is obtained, and the blended solution is the calcium carbonate oligomer synergistic APTS-POSS reinforced zwitterionic polymer material. The structural strength of the sandstone cultural relics can be enhanced, the outward migration rate of soluble salt in the sandstone cultural relics can be increased, and the salt weathering resistance of the sandstone cultural relics can be improved.
本发明公开了碳酸钙寡聚体协同APTS‑POSS增强两性离子聚合物材料、其制备方法及应用，以甲基丙烯酰氧乙基磷酰胆碱与甲基丙烯酸羟乙酯为反应单体进行自由基聚合反应，对反应产物进行纯化干燥并溶于有机溶剂，得到两性离子聚合物溶液；将γ‑缩水甘油醚氧硅丙基倍半氧烷与3‑氨基丙基三乙氧基硅烷溶于有机溶剂，加热反应，得到APTS‑POSS溶液；将碳酸钙寡聚体溶液、所述两性离子聚合物溶液和所述APTS‑POSS溶液共混，得到共混溶液，所述共混溶液即为碳酸钙寡聚体协同APTS‑POSS增强两性离子聚合物材料。本发明能够增强砂岩文物的结构强度并加快砂岩文物内可溶盐向外的迁移速率，有利于提高砂岩文物的防盐风化性能。
