This application discloses a
ceramic trademark glaze and its preparation method. The
trademark glaze comprises 50-60% low-temperature
frit; 5-10%
zinc oxide; 20-25%
zirconium silicate; 8-12% calcined kaolin; 1-2%
sodium carboxymethyl cellulose; 0.5-1.0%
sodium tripolyphosphate; and 1-5%
pigment. The
trademark glaze exhibits excellent printing performance, good thixotropic properties, smooth
screen printing, and clear line printing without breaks or ink bleeding; it can print clear lines as narrow as 0.3mm. The firing effect is ideal, with pure and vibrant colors and
high contrast with the white base glaze; the glaze surface is smooth and even, with no edge
curling. It has strong
environmental resistance, high
hardness after firing, and is resistant to acids and alkalis, maintaining
clarity even in harsh outdoor environments for extended periods. The process is widely adaptable, suitable for application to green or unglazed
ceramic bodies, and has good compatibility with conventional electrical porcelain firing processes.
