摘要: 为了制备出性能可调且满足多场景应用的砂岩石质文物灌浆材料,采用四角配料法,以水硬性石灰(NHL2)、硫铝酸盐水泥(SAC)、偏高岭土(MK)和水性环氧树脂(WER)为原料,制备出不同配方的灌浆材料,并对其力学性能、凝结时间、流动性、粘接强度等进行测试分析。结果表明,NHL2和MK含量较高的灌浆材料,抗压强度和粘接强度较低,适用于修复壁画或镶嵌图案。SAC和WER含量较高的灌浆材料,抗压强度和粘接强度较高,适用于修复断崖、悬岩型砂岩石质文物。WER和MK含量较高的灌浆材料,韧性和变形能力良好,适用于修复易受外界应力的砂岩石质文物。

Abstract: In order to prepare a sandstone stone cultural relic grouting material with adjustable properties and meet the requirements of multi-scene application, the four-angle experiment method was adopted. The hydraulic lime (NHL2), sulphoaluminate cement (SAC), metakaolin (MK) and water-based epoxy resin (WER) were used as raw materials to prepared grouting materials with different formulations. Furthermore, the mechanical properties, setting time, fluidity and abonding strength of the grouting material were tested and analyzed. The results indicate that the grouting material with higher content of NHL2 and MK is suitable for repairing murals or mosaic patterns because of its low compressive strength and bonding strength. The grouting material with higher content of SAC and WER has higher compressive strength and bonding strength, which is suitable for repairing cliff and overhanging sandstone stone relics. Besides, the grouting material with higher content of WER and MK has good toughness and deformation ability, and it is suitable for repairing sandstone cultural relics susceptible to external stress.

Key words: sandstone stone cultural relic, grouting material, four-angle experiment method, performance adjustment, multi-scene application
