Embodiment 1

[0016] React sodium isooctanoate and ruthenium trichloride at a molar ratio of 3:1. Before the reaction, mix sodium isooctanoate solution with alkane solvent evenly, add ruthenium trichloride, add 1‰ complexing agent, heat and stir at 110°C for 3 hours Prepare ruthenium isooctanoate, the percentages by weight of ruthenium isooctanoate and alkane solvent are 20% and 80% respectively, filter, wash and separate to obtain black ink.

Embodiment 2

[0018] React sodium isooctanoate and ruthenium trichloride at a molar ratio of 2:1. Before the reaction, mix sodium isooctanoate solution with alkane solvent evenly, add ruthenium trichloride, add 5‰ complexing agent, heat and stir at 110°C for 3 hours Prepare ruthenium isooctanoate, the weight percentages of ruthenium isooctanoate and alkane solvent are respectively 10% and 90%, filter, wash and separate liquid to obtain black ink.

Embodiment 3

[0020] React sodium isooctanoate with ruthenium acetylacetonate at a molar ratio of 3:1. Before the reaction, mix sodium isooctanoate solution with alkane solvent evenly, add ruthenium acetylacetonate, add 1‰ complexing agent, and heat and stir at 110°C for 3 hours. Ruthenium isooctanoate, the weight percentages of ruthenium isooctanoate and alkane solvent are respectively 30% and 70%, filter, wash and separate to obtain black ink.

Abstract

The invention discloses a preparation method of a black stain-bleeding ink for ceramic inkjet printing, wherein the black stain-bleeding ink is composed of the following components by the weight percentage: 10%-30% of a ruthenium metal complex, and 70%-90% of an organic solvent. The prepared black stain-bleeding ink has the advantages of high yield, high ruthenium content, homogenous phase of theink, no secondary treatment, narrow particle size distribution, no sedimentation, no clogging of printer nozzles, pure black after being printed and colored on a ceramic surface, and distinct patterns.

Description

Technical field: [0001] The invention relates to the technical field of ceramic decoration, in particular to a preparation technology of black bleeding ink for inkjet printing of ceramics. Background technique: [0002] Italy Meigao Company has been developing bleed ink since 2003. After more than ten years of technical reserves, it has become the leader in the field of bleed ink in the world. Ceramic inkjet bleed technology was introduced to China from Italy in 2013, and bleed ink was introduced in 2015. The research of the company has made a breakthrough in domestic color glaze enterprises and reached the stage of mass production. In the first half of 2015, leading enterprises in the industry such as Nobel, Dongpeng, and Mona Lisa successively released porcelain seepage tiles and produced them in batches, but the materials and technologies used came from abroad, and the output was not large. [0003] The research on domestic bleed ink is more than ten years later than tha...
