Abstract

The invention relates to the field of leather cultural object protection, and discloses a protection method for a saturated water leather cultural object. The protection method comprises the steps that firstly, dirt on the surface of the saturated water leather cultural object is brushed away through a brush, and then the saturated water leather cultural object is immersed in a leather protection solution A to be treated; secondly, the saturated water leather cultural object is placed in a container containing propylene glycol; thirdly, the saturated water leather cultural object is placed in a container containing ethyl alcohol; fourthly, the saturated water leather cultural object is placed in a container containing acetone; fifthly, the saturated water leather cultural object is placed in a container containing diethyl ether; sixthly, the saturated water leather cultural object is immersed in a leather protection solution B; seventhly, a catalyst is added in the leather protection solution B, and the saturated water leather cultural object is immersed in the leather protection solution B; and eighthly, the saturated water leather cultural object is aired under the natural condition. According to the method, the flexibility of the saturated water leather cultural object can be recovered, and meanwhile the mechanical strength and thermal stability of leather can be improved.

Description

technical field [0001] The invention relates to the field of protection of leather cultural relics, in particular to a protection method for saturated leather cultural relics. Background technique [0002] Humans began to use leather products very early, so a large number of leather products have been handed down to the world. Along with archaeological excavations, some exquisite leather products buried in the ground have been released. In the temperate zone, due to the perennial rainfall, many unearthed leather cultural relics have been under the groundwater for a long time. Due to the relatively constant external conditions, the leather cultural relics are in a saturated state. Due to archaeological excavations, a large number of these water-saturated leather cultural relics were unearthed. However, due to the huge changes in the external environment, the internal moisture of the water-saturated leather cultural relics continued to lose, causing the collagen fibers inside...
