Red pigment for ceramic ink-jet printing ink as well as preparation method and application of red pigment
The invention provides a red pigment for ceramic ink-jet printing ink. The red pigment is prepared from frit powder, aluminum hydroxide and iron oxide red, the D50 of the frit powder is 0.2 to 0.3 [mu] m; the particle size of the aluminum hydroxide is 8000 to 10000 meshes; the iron oxide red is iron oxide red, and the D90 of the iron oxide red is less than 3 microns. According to the invention, the ultra-fine high-temperature transparent frit powder, the ultra-fine aluminum hydroxide and the ultra-fine iron oxide red form the high-temperature coating pigment, the ceramic ink prepared from the pigment can generate bright red at a high temperature of 1200 DEG C, and the problem that the ink prepared from conventional ferrosilicon red and ferrozirconium red pigment does not develop color at a high temperature is solved. The ink can be applied to ceramic ink to replace ink wrapping red pigment or reddish brown ink, and compared with the current cadmium selenide sulfur red wrapping technology, the ink has the advantages of being environmentally friendly and free of a highly toxic substance cadmium.
本发明提出了一种陶瓷喷墨打印墨水用红色色素，由熔块粉、氢氧化铝及铁红组成；所述熔块粉的D50为0.2～0.3μm；所述氢氧化铝的粒径为8000～10000目；所述铁红为氧化铁红，所述铁红的D90小于3μm。本发明采用超微细高温透明熔块粉与超细氢氧化铝与超细铁红形成高温包覆色素，该色素制成的陶瓷墨水可以在高温1200℃产生鲜艳的红色，解决了常规硅铁红和锆铁红色料制备成墨水后在高温不发色的问题。该墨水可以应用在陶瓷墨水中替代包裹红色料墨水或红棕墨水，与目前的硫硒化镉包裹红技术相比,具有绿色环保、不存在镉这种剧毒物质的优点。
