Abstract

The invention provides bismuth-oxide-based black pigment used for glass digital inkjet printing and a preparation method of the bismuth-oxide-based black pigment. The bismuth-oxide-based black pigment is characterized in that preparation raw materials of the bismuth-oxide-based black pigment include bismuth oxide (alpha type Bi2O3), amorphous state silicon oxide (SiO2), boron oxide (B2O3), lithium oxide (LiO2), aluminum oxide (Al2O3), zirconium oxide (ZrO2) and copper chromite black (common industrial coloring materials); the preparation method includes the steps of evenly mixing bismuth oxide (alpha type Bi2O3), amorphous state silicon oxide (SiO2), boron oxide (B2O3), lithium oxide (LiO2), aluminum oxide (Al2O3) and zirconium oxide (ZrO2), conducting high energy ball milling to make the mixture sufficiently and mechanically alloyed, and mixing the powder obtained through ball milling with copper chromite black in a ball milling mode. The maximum particle size of the bismuth-oxide-based black pigment is smaller than 2 micrometers, the sintering temperature on glass is between 600 DEG C and 700 DEG C, the bonding strength between the bismuth-oxide-based black pigment and the glass is high, and the bismuth-oxide-based black pigment has wide application prospects in the field of digital inkjet printing.

Description

technical field [0001] The invention belongs to the technical field of glass digital inkjet printing, and in particular relates to a bismuth oxide-based black colorant for glass digital inkjet printing and a preparation method thereof. Background technique [0002] Glass digital inkjet printing technology, as a new non-contact, pressure-free, and plate-free printing technology, pushes the development trend of glass fashion, personalization, art, small batches, multi-color, low-carbon and environmental protection to a new level. a new height. Since my country introduced the first glass inkjet machine in 2009, the development of glass digital inkjet printing technology has advanced by leaps and bounds and has been widely used. Compared with the traditional glass surface printing technology, glass digital inkjet printing technology has the advantages of lifelike, delicate and clear product patterns, quick realization of personalized design and manufacturing, and high degree of...
