Problems solved by technology

At this stage, the field of domestic bronze restoration has not yet found a good way to deal with the "harmony but difference" between the restored parts of bronze cultural relics and the original, and the "identifiability" of cultural relics restoration is still a problem in the industry

preparation example Construction

[0028] The present invention also provides a method for preparing the above-mentioned identifiable fluorescent pigment for restoration of bronze cultural relics, comprising:

[0029] A) uniformly mixing the surface adhesive agent and the mineral pigment to obtain the first pigment;

[0030] B) uniformly mixing the organic ultraviolet fluorescent powder with a solvent to obtain a second pigment;

[0031] C) uniformly mixing the first pigment and the second pigment to obtain the identifiable fluorescent pigment for restoration of bronze cultural relics.

[0032] The above steps A), B) are not in sequence.

[0033] Preferably, the mixing temperature in the above step A) is 10-40°C.

[0034] The mixing temperature of the step B) is preferably 10-40°C.

[0035] The mixing temperature in step C) is preferably 10-40°C.

[0036] The above-mentioned surface adhesion agent, mineral pigment, organic ultraviolet fluorescent powder, solvent and their dosage are the same as above, and w...

Embodiment 1

[0041] Mix 10 parts by weight of shellac varnish and 3 parts by weight of iron red mineral pigment to obtain the first pigment;

[0042] 2 parts by weight of organic ultraviolet fluorescent powder and 4 parts by weight of ethyl acetate are mixed uniformly to obtain the second pigment;

[0043] uniformly mixing the first pigment and the second pigment to obtain the identifiable fluorescent pigment for restoration of bronze cultural relics;

[0044] The organic ultraviolet fluorescent powder is YG-B813 fluorescent blue organic ultraviolet fluorescent powder purchased from Dongguan Qianbian Chemical Technology Co., Ltd.

[0045] The color difference values ​​of the prepared fluorescent pigments and mineral pigments were detected by using an NH310 computer color difference meter. The evaluation criteria are shown in Table 1, and the test results are shown in Table 2.

[0046] Table 1 The relationship between the color difference value (ΔE) and the color change of mineral pigments...

Embodiment 2

[0054] According to the preparation method of Example 1, an identifiable fluorescent pigment for restoration of bronze cultural relics was prepared.

[0055] The ingredients are as follows:

[0056] 9 parts by weight of shellac varnish;

[0057] 4 parts by weight of mineral pigment azurite;

[0058] 2 parts by weight of organic ultraviolet fluorescent powder;

[0059] 4 parts by weight of ethyl acetate;

[0060] Organic ultraviolet fluorescent powder is the same as embodiment 1.

[0061] The color difference detection was carried out according to the test method of Example 1, and the results are shown in Table 2.

[0062] Use a brush to dip an appropriate amount of the above-mentioned fluorescent pigments and paint on the bronze cultural relics to be painted, and dry after the painting is completed.

[0063] Use 0.1ml of 5% acetic acid aqueous solution to drop on the painted part, and use 365nm purple light to irradiate, and its luminous intensity is good.

Abstract

The invention provides a recognizable fluorescent pigment for repairing a bronze cultural relic, which comprises the following components in parts by weight: 8-12 parts of surface adhesive agent, 2-4 parts of mineral pigment, 1-3 parts of organic ultraviolet fluorescent powder and 4-5 parts of solvent. When the fluorescent pigment provided by the invention is used for repairing the bronze cultural relic, the repaired part can not be easily detected under sunlight and can be easily detected under ultraviolet light, thereby solving the industrial problems of recognizability and beautiful appearance in cultural relic repair. The fluorescent pigment has the advantages of durable material color and low tendency to decolorization, and can not damage the cultural relic.

Description

technical field [0001] The invention relates to the technical field of restoration of cultural relics, in particular to an identifiable fluorescent pigment for restoration of bronze cultural relics, a preparation method thereof, and a restoration method of bronze cultural relics. Background technique [0002] my country's bronze cultural relics are the witness and carrier of human progress and civilization, and bronze ritual vessels are symbols of Chinese ritual culture. There is a huge amount of bronze cultural relics in existence, such as cooking utensils, food utensils, wine utensils, water utensils, musical instruments, carriage and horse decorations, bronze mirrors, belt hooks, weapons, tools and weighing instruments of all dynasties. After a long period of circulation or burial, most bronze cultural relics are presented in broken and incomplete forms. This requires professional repairs to restore the original appearance of the bronzes. However, with the infiltration ...
