LUMINOUS GLASS PRINTING INK,PREPARATION AND PRINTING METHOD ON GLASS PRODUCT THEREOF

摘要

A luminous glass printing ink is made of long persistence phosphor powder, transparent glass pigment, suspending agent, solid dispersing agent, and defoaming agent. The method for preparing the ink comprises: mixing the long persistence phosphor powder with the transparent glass pigment uniformly; adding to the molten mixture of suspending agent, solid dispersing agent, and defoaming agent; and then cooling while stirring. The printing method comprises screen-printing the ink on glassware to produce the luminous patterns; then increasing the temperature of the glass product to 520-650°C and holding the temperature for 20-30 min; and then cooling. The ink can withstand the temperature as high as 520-650°C and be used for screen-printing on glassware.
