Stone cultural relic surface crack repairing material and preparation method thereof
The invention discloses a stone cultural relic surface crack repairing material which comprises a dry material and a liquid material, wherein the dry material is composed of raw stone powder and an inorganic adhesive which are the same as those of a repaired stone cultural relic body; the raw rock powder comprises fine rock powder with the particle size of 20-60 meshes and coarse rock powder with the particle size of 60-100 meshes; the liquid material is a solution containing nanoscale silicon dioxide particles, the diameter of the nanoscale silicon dioxide particles is 10-15 nm, and the content of silicon dioxide in the solution is 30%-50%. The material is moderate in curing time, high in curing strength, good in ageing resistance and water resistance and good in compatibility with a cultural relic body, conforms to the principle that the original shape of the cultural relic is not changed during cultural relic protection, and can effectively solve the problem of repairing cracks on the surface layer of the stone cultural relic.
本发明公开了一种石质文物表层裂隙修复材料，包括与被修复石质文物本体相同的原石粉与无机粘合剂组成的干料，以及液料；所述述原石粉包括粒径为20～60目的岩石粉细料、粒径为60～100目的岩石粉粗料；所述液料为含纳米级二氧化硅颗粒的溶液，其中纳米级二氧化硅颗粒的径为10～15nm，溶液中二氧化硅含量为30％～50％。本发明材料固化时间适中，固化强度高，抗老化性能和耐水性能好，而且与文物本体兼容性好，符合文物保护不改变文物原状的原则，能够有效的解决石质文物表层裂隙修复的问题。
