Description
Technical Field
The invention belongs to the field of digital printing materials, and particularly relates to an oily ceramic bleeding color development ink toner and a preparation method and a use method thereof.
Background
The high-speed development of the digital technology greatly improves the quality of the printing technology and the popularization and application. The ceramic digital ink-jet printing technology is a ceramic surface decoration technology, and can be conveniently, quickly and automatically printed into various patterns through computer design, so that the patterns of ceramic tile products are more abundant, vivid and personalized, and have infinite creativity.
The color developing ink for ceramic digital ink-jet printing is low viscosity penetrating ink, and the color developing agent consists of organic metal salt of Cr, Mn, Fe, Co, Ni, Cu, Os, Ir, Pt, Ru, Rh, Pd, Au, Ag and lanthanide RE metal capable of being dissolved in organic solvent. The color developing ink has the capability of permeation and diffusion on the surface of ceramic tile glaze after being printed by an ink-jet printer, and the color developing agent is converted into metal oxide capable of presenting color at high temperature after being sintered at high temperature to form a pattern pre-designed by a computer. However, during the high temperature firing process, the chromophoric metal compound undergoes a series of chemical reactions, often resulting in unstable or even no chromophoric metal oxide. In order to solve the problem, the chinese patent application CN201510429407.0 (a toner for inkjet bleeding ceramic tile and its using method) describes ultrafine silica as a toner as a powder additive for ceramic glaze, but the mixing interface between the high temperature resistant granular silica and the molecular level color former is very obvious, which affects the uniformity of color development to some extent. There is no report on a toner of oil-soluble molecular level directly added to an oil-based ceramic bleeding color-developing ink.
