Embodiment 1

[0040] 1. Moistening crisp powder pottery painted cultural relics

[0041] Use a dropper to absorb methanol, and slowly add methanol dropwise on the surface of the crispy powder ceramic painted cultural relics until the entire surface of the crispy powder ceramic painted cultural relics is completely wetted.

[0042] 2. Preparation of reinforcing agent

[0043] Prepare the reinforcing agent according to the mass ratio of the following raw materials:

[0044]

[0045]

[0046] 3. Crisp powder pre-reinforcement

[0047] Use a 5.0mL syringe to draw 2.5mL of the reinforcing agent prepared in step 2, and drop it on the surface of the ceramic painted cultural relics that was completely wetted in step 1. After the surface is completely air-dried, dip the twice-diluted reinforcing agent with absorbent cotton and apply it On the surface of ceramic painted cultural relics, smear repeatedly 3 to 5 times to obtain reinforced ceramic painted cultural relics.

Abstract

The invention discloses a reinforcement and desalination method for a crisp powder ceramic painted cultural relic. The method includes: fully wetting the surface of a crisp powder ceramic painted cultural relic by methanol, then conducting pre-reinforcement by a reinforcing agent, then taking the mixture of acrylic acid strong water absorbent resin and styrene ion exchange resin as a desalting agent to perform desalination treatment on the pre-reinforced ceramic painted cultural relic, at the same time adding distilled water in the desalination process, utilizing the expansion pressure generated by re-water absorption expansion of the desalting agent to fix the position of a ceramic painted layer so as to make the painted layer tightly pressed to a ceramic tire, thus preventing bubbles and displacement of the painted layer, reducing artificial cladding operation, and improving the safety coefficient in the desalination process. The method provided by the invention has a simple operation process, the desalination process has no influence on the pre-reinforcement effect, and the desalination efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of restoration of cultural relics, and in particular relates to the reinforcement of crisp powder layers (including pottery tires and painted layers) of pottery painted cultural relics and subsequent desalination treatment after reinforcement. Background technique [0002] The presence of soluble salt in pottery painted cultural relics (including painted pottery, pottery figurines, and pottery horses) is one of the important causes of salt damage. After unearthed pottery painted cultural relics, because they contain soluble and slightly soluble salts, when the temperature and humidity of the outside world change, the soluble salts will repeatedly "precipitate-dissolve-precipitate", and the crystallization pressure generated during this process will lead to pottery Serious diseases of salt-damaged crisp powder appeared in tire and painted layers. The salt-damaged crisp powder directly causes the destruction ...
