甘肃武威磨咀子出土汉代木牛车抢救性复原修复

甘肃武威出土的汉代木牛车，两轮巨大，造型简约、独特，是河西走廊乃至西域特有样式。器物因受埋藏环境和保存环境影响，具有糟朽木器的典型特征，车体结构因腐蚀严重而坍塌散架，木质收缩变形，车轮残损、残缺，车辕、车轴断裂，车蛉、车羝残失，车毂及附属部件酥解、粉化，以致无法组合成形。为此，对这批木牛车实施了抢救性复原修复。修复工作采用考古出土的汉代棺板木作为修复材料，使用棺板木木屑及聚醋酸乙烯乳液混合物用于补全、补缺和外观做旧；回收利用老化的竹签条或棉签棒对车辐进行了复原；采用滴管渗透的方法，使用PB72的乙酸丁酯或丙酮试剂对糟朽部件实施加固；最后，采用器物原始的铆眼套合技术，使木牛车历史原貌得到复原，修复效果良好。本工作可为其后糟朽木器的修复提供科学可行的材料和技术。
