Abstract

The objective of the invention is to provide waterborne ceramic digital spray-painting ink and a preparing method thereof to overcome defects of present waterborne ceramic digital spray-painting ink. To achieve the objective, the provided ink is prepared by mixing water, glycerol, propylene glycol, glycol, polyethylene glycol, n-butanol, a dispersant, a coupling agent, a surfactant, a defoamer, an anti-settling agent, a sterilizing agent and pigment. The water, the glycerol, the propylene glycol, the glycol, the polyethylene glycol, the n-butanol, the dispersant, the coupling agent, the surfactant, the defoamer, the anti-settling agent, the sterilizing agent and the pigment are fully mixed according to a ratio, the mixture is ground by a sand mill for 5 h at a speed of 2000 r / min until the granularity is about 150-350 nm, viscosity and surface tension of the product are tested, and the ink is obtained when the viscosity and surface tension are qualified.

Description

technical field [0001] The invention relates to a ceramic digital inkjet ink, in particular to a water-based ceramic digital inkjet ink and a preparation method thereof. Background technique [0002] Along with the progress of society, although oil-based ceramic digital inkjet ink has played a huge role in our lives, the organic substances such as benzene contained in them are harmful to the human body, and their harm cannot be eliminated for a long time. Meet the requirements of building an environment-friendly society, and will gradually be replaced by environment-friendly products. The water-based ceramic digital inkjet printing ink has gradually entered our sight in line with the trend of the times. Because they do not contain organic substances such as benzene, they are harmless to the environment and are environmentally friendly products, which will gradually become the mainstream of future products. [0003] Foreign experts started to research and develop digital cer...
