Problems solved by technology

[0003] At present, in the color restoration work on the surface of cultural relics, the pigment layer on the surface of cultural relics is deteriorated, which leads to the failure of the rubber material, increased light scattering of the pigment, poor color rendering, and it is difficult to distinguish the original color, which causes great difficulty in the restoration work.

Abstract

This application relates to the field of protection and restoration of cultural relics, and specifically discloses a color matching method for protection and restoration of cultural relics, including the following steps: S1, surface cleaning; S2, pigment protection: after the surface of cultural relics is completely dry, spray on the surface of the pigment layer of faded cultural relics to develop color Restorative agent; S3, use colorimeter to read the color and analyze the cause of fading disease, and make a color standard database according to the color of the pigment layer of cultural relics; S4, computer scan and design the formula of repairing pigment; S5, the pigment prepared by using the formula is effective on cultural relics Repair missing parts. This application improves the color depth of the surface of cultural relics before color complementation, facilitates color extraction and color complement operations, and reduces the difficulty of restoration.

Description

technical field [0001] This application relates to the field of cultural relics protection and restoration, and more specifically, it relates to a color matching method for cultural relics protection and restoration. Background technique [0002] China has a history of more than 5,000 years and has left a large number of cultural relics and historic sites. These cultural relics and historic sites contain important historical information such as culture, art, economy, and technology for historical and archaeological research. They are one of the carriers of Chinese civilization. . These cultural relics have been buried underground for a long time. As time goes by, they are affected by environmental factors such as air oxidation and water erosion. The surface of the cultural relics often suffers from varying degrees of fading or decolorization, requiring restoration of cultural relics. [0003] At present, in the color restoration work on the surface of cultural relics, the p...
