Problems solved by technology

[0005] But its shortcoming is: for the restoration of ancient ceramic cultural relics, it needs to be restorable. After the ceramics repaired by epoxy resin are cracked again after a long time, the original epoxy resin is difficult to remove. Restoration again brought great difficulty
In addition, the difficult removal of epoxy resin also brings trouble when research needs to be carried out on the restoration of ceramics

Abstract

Relating to the technical field of protection of cultural relics, the invention discloses an ancient ceramic microfissure regenerative repair method. The method includes: A). dissolving a copolymer of methyl acrylate and ethyl methacrylate in acetone to prepare a first adhesive; B). subjecting the first adhesive and an epoxy resin adhesive to mutual dissolution to obtain a composite adhesive; C). coating ceramic microfissures with the composite adhesive, 5-15min later, scraping away the composite adhesive remaining on the ceramic surface, then placing the ceramic at a ventilation place for 6-8d, thus finishing first repair of the ceramic; and D). after the first repair, when the repaired ceramic needs restoration, acetone is added to the ceramic microfissures, and after dissolution of the adhesive at the microfissures, cleaning the ceramic, thus finishing ceramic restoration. The method provided by the invention has the advantages that: 1. the method is simple to operate; 2. it has no influence to ceramic aesthetics; 3. it has no influence to ceramic authenticity; and 4. the composite adhesive has reversibility, and can perform regenerative repair on ceramic microfissures.

Description

technical field [0001] The invention relates to the technical field of cultural relics protection, in particular to a reproducible repair method for micro-cracks in ancient ceramics. Background technique [0002] Ceramic refers to a material made of clay and fired at a certain temperature. It has high hardness but poor plasticity. In China, the history of ceramics can be traced back to 10,000 BC. The production of ancient Chinese ceramics has reached The level is quite high, leaving many precious ceramic heritages for future generations, but most of them are buried underground, and most of them are incomplete after archaeological excavations, and due to various uncertain factors, relatively well-preserved ones will also bring There are some tiny cracks, which are a hidden danger to the ceramic itself. Therefore, repairing these micro cracks in time is very important for the protection of ceramics. However, most of the ordinary adhesives currently used in China , for the res...
