Dynamic Research of the Adhesion in the Deteriorated Object with Medicine Impregnation

由于构件的丢失造成差距，使文物的强度降低，因此进行了保护处理、药物浸渍、连接和填充。本研究对出土的金属器、陶器、石器和变质的民间木器进行了模拟加工。通过强度衰减的测定，考察了胶粘剂、填料、树脂和溶剂等材料的相容性。首先，为了考察环氧填料在密封状态下成型后，浸泡在有可能残留在文物中的药物中后，对冲切工具的剪切强度进行了测定。结果发现，使用硫醇硬化剂的环氧树脂，由于极性溶剂而导致的强度降低较大，使用胺硬化剂时，强度降低较小。从颜色和热特性的变化也可以看出这一点。接下来，为了检查对粘合剂的影响，制作了粘合在一起的模拟文物，并浸泡在药物中，由于压缩剪切和弯曲强度测试，测量了粘合剂的强度。结果，在模拟铁器中观察到粘附被锈阻碍。此外，对于模拟陶器，由于材料强度小，在许多情况下观察到材料的破坏。通过上述研究，对于保护和修复材料所需的特性，“那些扩大文化资产强度的，那些不给负面影响的，当必要性消失时，那些可以去除的”。对于我们来说，有必要精心选择符合文化资产的粘合剂。

Strength of the relic has decreased by the component's being lost and causing the gap, therefore, conservation processing, the medicine impregnation, the connecting and the filling are conducted. In this research, the processing of the excavation metalware, the earthenware, the stoneware and the deteriorated folklore woodenware was simulated. By the strength decrease being measured, it was investigated the compatibility of material such as adhesive, filler, resin and solvent.First, in order to inspect the influence on the filler, the epoxy filler formed in seat condition, after soaking in the medicine which has the possibility of remaining in the relic with the processing, it measured the shearing strength of punch tool. As a result, the epoxy resin which uses the thiol hardener, to the strength decrease by the polar solvent was large, uses the amine hardener it was found that strength decrease is small. This was supported even from change of color and thermal characteristic.Next, in order to inspect the influence on the adhesive, the simulated relics glued together were produced, and soaking in the medicine, the adhesiveness was measured due to compression shearing and bending strength test. As a result, in the simulated ironware it was observed that adhesion is obstructed by rust. In addition, as for the simulated earthenware, the destruction of the material was observed in many cases because material strength is small.Through the research above, as for the characteristic which is required from conservation and restoration material, "those which enlarge the strength of the cultural assets, those which do not give the negative influence, and when necessity is gone, those which can be removed". As for us it is necessary to select the adhesive which conforms to the cultural assets finely.
