Embodiment 1

[0030] The bronze artifacts to be restored are made of tin bronze, and the cylindrical support is broken.

[0031] (1) Pre-repair treatment: Perform pre-repair treatment on the area of ​​the bronze ware to be repaired, remove surface oil and rust, and open welding grooves.

[0032] (2) Establish a restoration model: Measure the relevant dimensions of the bronze cultural relics to be restored (Y-shaped groove, gap 5mm, blunt edge 4mm), use the 3D modeling software SOLIDWORKS to establish a virtual restoration 3D model of the area, and use a 3D printer to obtain physical model;

[0033] (3) Making packaging molds: According to the physical model, use fireproof mud to make matching packaging molds, and dry the packaging molds for later use;

[0034] (4) Preparation of solder powder: Determine the solder powder formula for exothermic reaction according to the composition of the bronze cultural relics to be repaired. The mass percentage of each material is 10% Na 2 SO 4 Powder, ...

Embodiment 2

[0041] The bronze artifacts to be repaired are made of tin bronze, and the complex shape of the knife handle is partially damaged.

[0042] (1) Pre-repair treatment: Pre-repair the area of ​​the bronze ware to be repaired to remove surface oil and rust.

[0043] (2) Establish a repair model: use a 3D scanner to directly obtain a 3D model of the area to be repaired, perform virtual repair, and use a 3D printer to obtain a solid model;

[0044] (3) Making packaging molds: According to the physical model, use fireproof mud to make matching packaging molds, and dry the packaging molds for later use;

[0045] (4) Preparation of solder powder: Determine the solder powder formula for exothermic reaction according to the composition of the bronze cultural relics to be repaired. The mass percentage of each material is 11% Na 2 SO 4 Powder, 38% Cu 2 O powder, 11% Al powder, 2% CaF 2 Powder, 1% borax, 24% Cu powder, 11.5% Sn powder, 1.00% PbO powder, 0.25% Ag powder, 0.17% As powder,...

Embodiment 3

[0052] The bronze artifacts to be restored are made of lead-tin bronze, and the complex shape is full of local defects.

[0053] (1) Pre-repair treatment: Pre-repair the area of ​​the bronze ware to be repaired to remove surface oil and rust.

[0054] (2) Establish a repair model: use a 3D scanner to directly obtain a 3D model of the area to be repaired, perform virtual repair, and use a 3D printer to obtain a solid model;

[0055] (3) Making packaging molds: According to the physical model, use fireproof mud to make matching packaging molds, and dry the packaging molds for later use;

[0056] (4) Preparation of solder powder: Determine the solder powder formula for exothermic reaction according to the composition of the bronze cultural relics to be repaired. The mass percentage of each material is 11% Na 2 SO 4 Powder, 34% Cu 2 O powder, 10% Al powder, 1.5% CaF 2 Powder, 2% borax, 15% Cu powder, 10% Sn powder, 18% Pb powder, 0.3% Ag powder, 0.15% As powder, 0.05% Sb powde...

Abstract

The invention belongs to the field of archaeology and particularly relates to a repairing method for a broken and defected bronze ware culture relic. The repairing method includes the following steps that firstly, treatment before repairing is conducted; secondly, a repairing model is established; thirdly, a packaging die is prepared; fourthly, welding powder is configured; fifthly, die assembling is conducted; sixthly, power is loaded; seventhly, repairing is conducted; eighthly, aftertreatment is conducted. According to the repairing method, due to an exothermic reaction of self-propagating powder, high-temperature metal liquid with basic components consistent with those of the bronze ware culture relic is obtained, the metal liquid is solidified to be in a specific shape in the packaging die and is firmly metallurgically bonded to a base body, and therefore the repairing of the broken and defected bronze ware culture relic is achieved. According to the repairing method for the broken and defected bronze ware culture relic, filler metal components can be flexibly adjusted according to basic components of bronze ware or special requirements, equipment of the repairing method is simple, energy such as electric energy and light energy does not need to be consumed in the repairing process, the repairing cost is low, the repairing method is suitable for repairing various forms of broken and defected bronze ware culture relics, universality is good, the repairing speed is high, efficiency is high, and field operation can be achieved.

Description

technical field [0001] The invention belongs to the field of archaeology, and in particular relates to a restoration method for broken and defective bronze ware cultural relics. Background technique [0002] my country is an ancient civilization with a long history. With the development of Chinese archaeology, a large number of bronze artifacts have been unearthed. Bronze cultural relics are extremely important and precious historical materials for studying the history of our country's history, culture, art, and science and technology development. It directly tells archaeologists and historians the real history, and at the same time gives scientific researchers real materials to analyze the production technology of the ancestors at that time . Many bronze artifacts are rare treasures, even priceless. It is our bounden duty to protect the bronze cultural relics. [0003] Bronze wares mainly refer to bronze wares made by ancient traditional crafts, with tin, lead and copper...
