南方潮湿地区壁画表面加固与裂隙灌浆材料的评价研究

Evaluation of materials for mural surface reinforcement and fracture grouting in humid areas of south China

为弥补我国南方潮湿地区壁画保护材料研究的欠缺,模拟南方气候条件对壁画表面加固和裂隙灌浆材料进行保护效果的评价研究。通过前期预实验以及表面光泽度、防水性、耐老化性等测试评价得到:质量分数1.5%的RS1930纯丙乳液具有较好的表面加固效果;传统石灰中添加占石灰质量3.0%左右的ZB-SE-3A纯丙乳液和2.0%左右的纳米材料配制而成的灌浆材料具有较好的强度、防霉性、防水性与耐老化性,适合作为潮湿地区壁画灌浆加固材料。

To make up for the lack of research on conservation materials for murals in humid areas of south China,we evaluated the conservation effects of some materials used for mural surface reinforcement and fracture grouting under a simulated climatic condition of south China.Through evaluations of surface gloss,water resistance,aging resistance and other properties,we found that 1)1.5%(mass fraction)RS1930 pure acrylic emulsion had better surface-reinforcing effect and 2)traditional lime added with ZB-SE-3A pure acrylic emulsion(about 3%of lime mass)and nano materials(about 2%of lime mass)demonstrated good strength,mildew resistance,water resistance and aging resistance,and was suitable as a fracture-grouting material for murals in humid areas.
