example 1

[0015] Example 1: For a missing block with a thickness of about 30 mm, take white marble powder with a particle size of 120-140 mesh, mix it with a weight ratio of white marble powder: acrylic emulsion = 4:1, stir well and spread it on the surface to be repaired , use a trowel to compact and smooth, the thickness is 5mm, to repair the bottom layer; prepare a mixed system of white marble powder: acrylic acid emulsion = 10:1, spread it on the surface where the above bottom layer construction has been carried out, and compact it with a trowel Smooth it out, with a thickness of 5mm, which is the middle layer; prepare a mixed system of white marble powder: acrylic emulsion = 8:1, stir well and spread it on the surface that has been constructed by the middle layer, which is the surface layer, with a thickness of 5mm, and then use a trowel Compacting, shaping according to the outer contour of cultural relics.

example 2

[0016] Example 2: For a missing block with a thickness of about 20 mm, take white marble powder with a particle size of 120-140 mesh, mix it with a weight ratio of white marble powder: acrylic emulsion = 6:1, stir well and spread it on the surface to be repaired , compacted and smoothed with a trowel, the thickness is 5mm, to repair the bottom layer; prepare a mixed system of white marble powder: acrylic acid emulsion = 8:1-10:1, spread it on the surface where the above bottom layer construction has been carried out, and use The trowel is compacted and smoothed, with a thickness of 8mm, which is the middle layer; prepare a mixed system of white marble powder: acrylic emulsion = 6:1, stir well and spread it on the surface that has been constructed by the middle layer, which is the surface layer, with a thickness of 5mm. Then use a trowel to compact it and shape it according to the outer contour of the cultural relic.

example 3

[0017] Example 3: For a missing block with a thickness of about 40 mm, take white marble powder with a particle size of 80-120 mesh, mix it with a weight ratio of white marble powder: acrylic emulsion = 4:1, stir well and spread it on the surface to be repaired , use a trowel to compact and smooth, the thickness is 5mm, to repair the bottom layer; prepare a mixed system of white marble powder: acrylic acid emulsion = 8:1, stir well and spread it on the surface that has been subjected to the above bottom layer construction, and compact it with a trowel Smooth it out, with a thickness of 10mm, which is the middle layer; prepare a mixed system of white marble powder: acrylic emulsion = 6:1, stir it evenly and spread it on the surface that has been constructed by the middle layer, which is the surface layer, with a thickness of 1mm-5mm, and then use The trowel is compacted and shaped according to the outer contour of the cultural relic.

Abstract

The invention discloses a method for repairing a white marble cultural relic, and belongs to the field of cultural relic repairing. The method of the invention comprises the following steps of: cleaning a to-be-repaired part of the white marble; mixing white marble powder and acrylic emulsion in a weight ratio of 4:1-6:1, spreading on a to-be-repaired surface, and compacting and screeding with a trowel to form a repairing bottom layer; mixing the white marble powder and the acrylic emulsion in the weight ratio of 8:1-10:1, spreading on the surface of the repairing bottom layer, and compacting and screeding with the trowel to form an intermediate layer; and mixing the white marble powder and the acrylic emulsion in the weight ratio of 6:1-8:1, spreading on the surface of the intermediate layer, and compacting with the trowel. When the white marble needs to be repaired for the second time, the repairing material only needs to be damaged at a crack layer, and secondary repairing is performed on the crack layer without causing repairing damage to a white marble cultural relic matrix, so the reversibility of the process of a repairing principle is met.

Description

technical field [0001] The invention relates to a method for repairing white marble cultural relics, belonging to the field of cultural relics restoration. Background technique [0002] As a high-grade stone, white marble has been favored since ancient times, and it is one of the important stone carving stones. Royal gardens such as the Forbidden City, Taimiao, Summer Palace, and Temple of Heaven in Beijing have a large number of white marble railings, sculptures and other cultural relics, adding a solemnity to the royal gardens. Over the years, the outdoor white marble cultural relics have defects such as pulverization and fracture, and need to be repaired. The invention mainly repairs the loss of white marble cultural relics. [0003] Data retrieval shows that the patent No. 99100477.9 discloses a stone carving repair technology. This patent uses the same stone material as the stone carving itself, which is crushed and mixed with paint to form a stone slurry paint. This...
