Problems solved by technology

After a large number of precious pottery painted cultural relics from the Han Dynasty, Tang Dynasty and other dynasties were unearthed, due to the soluble and slightly soluble salts contained in them, the painted layers showed serious cracking, falling off, and crispy powder due to the influence of the external environment; more serious The pottery body also appeared the phenomenon of crispy powder falling off, so that the original appearance of the precious pottery painted cultural relics was seriously damaged, and it was on the verge of destruction, or even disappeared forever.

Embodiment 1

[0016] Taking the preparation of 100g pottery painted cultural relic reinforcement paint as an example, the components used and their mass composition are as follows:

[0017]

[0018] According to the dosage of the above-mentioned components, first dissolve ethyl cellulose completely in ethanol, then add trimethyl resin and UV-9, stir until completely dissolved, and then fill it to complete the preparation of the finished product of reinforced coating for ceramic painted cultural relics .

Embodiment 2

[0020] Taking the preparation of 100g pottery painted cultural relic reinforcement paint as an example, the components used and their mass composition are as follows:

[0021]

[0022] Its preparation method is identical with embodiment 1.

Embodiment 3

[0024] Taking the preparation of 100g pottery painted cultural relic reinforcement paint as an example, the components used and their mass composition are as follows:

[0025]

[0026] Its preparation method is identical with embodiment 1.

[0027] Use the X-RiteVS-450 spectrophotometer to test the color difference before and after three different ceramic simulated samples, and evaluate according to the American Society for Testing and Materials standard ASTM D1729-89 "Visual Evaluation of Color Difference of Opaque Materials". The results are shown in Table 1.

[0028] Table 1:

[0029]

[0030] It can be seen from Table 1 that the color difference before and after the ceramic simulation sample treated by the coating of the present invention is small.

Abstract

The invention discloses a ceramic painted relic reinforcing paint, which comprises the following components in percentage by weight: 2.2 to 2.8% of three methyl resin, 3.2 to 3.6% of ethyl cellulose, 91.7 to 96.2% of ethanol, and 0.2 to 0.4% of UV-9. The invention also discloses a preparation method of the reinforcing paint. The preparation method comprises the following steps: according to the total weight of needed paint, calculating the amounts of the components (three methyl resin, ethyl cellulose, ethanol, and UV-9); completely dissolving ethyl cellulose into ethanol, then adding three methyl resin and UV-9 into the ethanol solution of ethyl cellulose, stirring to completely dissolve three methyl resin and UV-9, and filling the solution into containers to obtain finished products. The reinforcing paint has the functions of penetrating water and salts, and preventing oxidation, can be used to reinforce the powdery layers of ceramic painted relics, and has a strong performance on sealing and protecting the painted layers; the UV and aging resistant property of the reinforcing paint is strong, the color difference change of the processed painted layer is small, and the reinforcing effect is prominent.

Description

technical field [0001] The present invention relates to the technical field of cultural relics protection, in particular to a pottery color-painted cultural relic reinforcement coating and a preparation method thereof. Background technique [0002] Pottery painted cultural relics are precious and carry very important artistic value and historical information. The removal of soluble salt from salt-damaged crisp powder ceramic painted cultural relics (including painted pottery, pottery figurines, and pottery horses) is a long-term unsolved problem in the field of cultural relics protection. After a large number of precious pottery painted cultural relics from the Han Dynasty, Tang Dynasty and other dynasties were unearthed, due to the soluble and slightly soluble salts contained in them, the painted layers showed serious cracking, falling off, and crispy powder due to the influence of the external environment; more serious The pottery body of the former also appeared the phen...
