Abstract

The invention discloses a color protective of weathered fading coloured drawing on the ancient cultural relics, which comprises the following parts: 0.30-0.72% di(1,2,2,6,6-pentamethylphenol-4-piperidine base)-sebacate, 0.14-0.28% phosphorous acid tri(nonyl phenol) ester, 0.06-0.15% phosphorous acid benzene diisophthalate, 0.42-0.90% vinylidene fluoride-trifluorochloroethylene copolymer, 0.30-0.80% methyl methacrylate-styrene copolymer, 42. 00-46. 00% acetone, 10.00-12. 00% acetic ester, 10.00-12. 00% butyl acetate, 10.00-12. 00% amyl acetate, 10.00-10.00% methyl-ethyl ketone and 10.00-12. 00% cellosolve.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a color-developing protective agent capable of displaying weathered and faded ancient cultural relic paintings. Background technique [0002] Ancient murals, cultural relics, and architectural paintings have been severely weathered and faded after hundreds or even thousands of years, and the phenomenon of disappearing is common. It has occurred on the epitaphs, epitaphs, and architectural paintings, causing national treasures and state-level cultural relics to lose their original value, and bringing troubles to historical and archaeological research. For example, the only discovered and precious murals of the Qin Dynasty court were faded due to severe weathering, and most of the pictures of four horses and chariots were on the verge of disappearing. Xianyang Museum collects and exhibits the large-scale painted terracotta warriors and horses of the Western Han Dynas...
