Problems solved by technology

[0004] Ceramic materials generally have high hardness, but poor plasticity, and are prone to damage or cracks. It is necessary to repair and cover the damaged or cracked ceramics
The current ceramic seam-shielding materials tend to shrink easily after curing, and the adhesion to ceramic cracks is not high, which may easily cause the seam-shielding material to fall off, and the water resistance is not high

Abstract

The invention discloses a repair material for ceramics, which comprises a component A and a component B in a weight ratio of 40:3-5, wherein the component A is prepared from the following raw materials in parts by weight: 70-90 parts of epoxy resin, 15-25 parts of furan resin, 15-25 parts of composite filler, 1-5 parts of polyphenyl polymethylene polyisocyanate, 2-4 parts of an anti-aging agent, 2-4 parts of a dispersing agent and 20-40 parts of a diluent; and the component B is prepared from the following raw materials in parts by weight: 6-9 parts of 2ethyl4methylimidazole, 1-2 parts of p-toluenesulfonic acid and 10-15 parts of diluent. The invention further discloses a preparation method of the repair material for the ceramic. According to the invention, through the mutual cooperation of all the substances, the composite material has good cohesiveness and water resistance, the shrinkage rate after curing is low, and the composite material is prevented from falling off from the ceramic easily through the interaction of the two aspects of increasing the cohesiveness and reducing the shrinkage rate.

Description

technical field [0001] The invention relates to the technical field of crack repair materials, in particular to a repair material for ceramics and a preparation method. Background technique [0002] Ceramics is the general term for pottery and porcelain. The Chinese invented pottery as early as about 8000-2000 BC (Neolithic Age). In addition to the use of tableware and decoration, it also plays an important role in the development of science and technology. [0003] Ceramic materials are mostly oxides, nitrides, borides and carbides. Common ceramic materials are clay, silicon carbide, kaolin and so on. The raw material of ceramics is obtained by quenching the earth's original large resource clay. The nature of clay is tough, it can be molded when exposed to water at room temperature, it can be carved when it is slightly dry, and it can be ground when it is completely dry; it can be made into pottery when it is fired at 700°C; [0004] Ceramic materials generally have hi...
