Abstract

The invention discloses bright sinking ink which comprises the following raw materials in percentage by mass: 25-45% of a sinking agent, 15-20% of a brightening agent, 1-3% of a dispersing agent and 30-70% of a solvent. Tests show that the bright sinking ink meets technical index requirements of a national standard GB / T 4100-2006 Ceramic Tile and national standards GB6566-2010 Radioactive Nuclide Limit for Building Material, HJ / T 297-2006 Technical Requirement for Environmental Labeling Products Ceramics Tiles and EN 101: 1992 Vitreous and Porcelain Enamels-Determination of Surface Scratch Hardness According to the Mohs Scale, and meanwhile has excellent sinking effects and good surface gloss.

Description

technical field [0001] The invention relates to the ceramic ink-jet ink field, in particular to a bright light sinking ink. Background technique [0002] Sinking ink is an inkjet printing ink for ceramic decoration that is applied to ceramics by inkjet printing and fired to achieve a sinking effect in a local area of ​​the surface. This kind of ink can overcome the surface tension and penetrate downwards to a certain depth in the ceramic tile under certain process conditions by means of ion diffusion and surface adsorption. Compared with ordinary glazed tiles, polished crystal tiles, etc., the inkjet decorative ceramic tiles formed in this way have higher wear resistance, more moist texture, more natural and realistic textures, and are suitable for interior and exterior wall decoration of various buildings. . Based on the above advantages, more and more domestic ceramic enterprises are investing in the research of sinking ink. However, the surface of ceramic tiles decorat...
