Abstract

The invention relates to waterborne ink for ceramic inkjet printing. The waterborne ink is prepared from the following raw materials: 20-50 parts of ceramic pigment, 2-7 parts of a dispersing agent, 2-5 parts of a surface active agent, 2-3 parts of a resin bonding agent, 2-6 parts of a regulating agent, 0.1-0.5 part of an auxiliary and the balance of water. The waterborne ink provided by the invention contains no toxic organic solvent, achieves certain physical and chemical indexes through mechanical dispersion process treatment, is excellent in comprehensive performance, lower in cost, strongin practicability and can adapt to most of inkjet printers on the market.

Description

technical field [0001] The invention relates to the technical field of ceramic inkjet printing, in particular to an ink used in ceramic inkjet printing. Background technique [0002] With the development of market economy and computer technology, the existing traditional ceramic decoration methods can no longer meet the needs of the market. The introduction of modern computer technology is an inevitable trend in the future development of ceramic product design. At present, the new process inkjet printing technology for moldless molding is becoming a research hotspot worldwide, and various ceramic inks matching it have also appeared one after another. Inkjet printing is a very potential decoration technology. The method is to make colorants into multi-color inks for ceramic surface decoration, and print multi-color inks directly onto the ceramic surface for decoration through a computer-controlled printer. [0003] One of the keys to ceramic inkjet technology lies in the de...
