Problems solved by technology

[0004] However, due to the consideration of environmental protection technology, the existing technology mostly adopts the method of low-temperature fast-firing; when the re-firing temperature is lower than 1200°C, the expansion rate of kyanite will decrease, which is not enough to completely offset the flux components during the porcelainization process. Due to the shrinkage volume caused by burning, cracks will still appear after firing, and the ideal repair effect cannot be achieved

Abstract

The invention discloses a ceramic patching primer. The ceramic patching primer is of a lump shape formed through subjecting a patching primer composition to mixing and refining, wherein the patching primer composition comprises the following ingredients in parts by weight: 100 parts of primer dry powder, 13-20 parts of water and 5-12 parts of sodium carboxymethyl cellulose, wherein the primer drypowder comprises the following ingredients in percentage by weight: 25% to 35% of quartz, 34% to 44% of waste porcelain powder, 16% to 26% of mullite and 8% to 12% of zirconium silicate. The ceramic patching primer is applicable to a low-temperature quick-burning environment-friendly process, the volume shrinkage is low after burning, cracking is not easy, and the range of a patchable wounded areais wide.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a ceramic repair primer, a repair surface glaze, a preparation method and a ceramic repair method. Background technique [0002] At present, the repairing material used to repair cracked sanitary ware is required not to shrink after firing, so as to ensure that the defects of the sanitary ware can be completely smooth and crack-free after firing, and at the same time, the repairing material is required to have a lower firing temperature. If a large amount of flux raw materials are added to the repair material, such as using a large amount of flux components such as feldspar, frit, zinc oxide, talc and glaze powder in a molten state to achieve porcelainization, due to the large amount of flux components added in this formula, After firing, the shrinkage ratio is large, it is easy to crack, and the repair effect is poor. In addition, since the repairing base material is filled...
