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

由于构件的丢失造成缺口，导致文物强度降低，因此进行了保存处理、药物浸渍、连接和填充。本研究模拟了出土的金属器皿、陶器、石器和变质的民俗木器的加工过程。通过强度下降的测定，考察了胶粘剂、填料、树脂、溶剂等材料的配伍性。首先，为了考察在底座状态下形成的环氧填料在浸泡在加工过程中有可能残留在残留物中的药物中对填料的影响，对冲模进行了剪切强度测试。结果表明，使用硫醇固化剂的环氧树脂，对极性溶剂的强度降幅较大，使用胺类固化剂的强度降幅较小。接下来，为了考察对粘结剂的影响，制作了粘接在一起的模拟文物，并将其浸泡在药物中，通过压缩剪切和弯曲强度试验测量了粘附性。结果，在模拟的铁器中，观察到粘附力被锈蚀所阻碍。此外，对于模拟陶器，由于材料强度较小，许多情况下都观察到了材料的破坏。通过以上研究，对于保护和修复材料所要求的特征，即“那些放大了文化资产的强度，那些不会产生负面影响的，当必要的时候，可以移除的”。对于我们来说，选择符合文化资产的粘合剂是很有必要的。

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.
