Nanometer composite reinforcing material solution, preparation method and application
The invention relates to a nano composite reinforcing material solution, a preparation method and application, the reinforcing material solution comprises effective components and a carrier, the effective components comprise nano calcium hydroxide and graphene quantum dots, and the carrier is ethanol; the preparation method comprises the following steps: preparing a composite material of nano calcium hydroxide and graphene quantum dots by adopting a coprecipitation method, and then centrifugally cleaning to obtain a colloidal solution of the nano calcium hydroxide and graphene composite reinforcing material dispersed in liquid ethanol. The composite reinforcing material is uniformly dispersed in ethanol, can be stored for a long time, has a good reinforcing effect on marble, limestone and other calcium-based stone cultural relics with loose structures, and is simple in preparation method and convenient to apply compared with existing materials.
本发明涉及一种纳米复合加固材料溶液、制备方法和用途，所述加固材料溶液包括有效组分和载体，有效组分包括纳米氢氧化钙和石墨烯量子点，载体为乙醇；其制备方法包括：采用共沉淀法制备纳米氢氧化钙和石墨烯量子点的复合材料，之后通过离心清洗，得到分散在液态乙醇中的纳米氢氧化钙和石墨烯复合加固材料胶体溶液。该复合加固材料在乙醇中分散均匀，可长期保存，对结构疏松的大理石及石灰岩质等钙基石材的文物加固效果好，与现有材料相比，制备方法简单，便于应用。
