Glazed brick production method

The invention relates to a glazed brick production method, which comprises: (1) preparing a ceramic brick billet, (2) spraying a hydrophobic agent, spreading frit particles, spraying a curing agent, and firing to form a frit layer, (3) covering a glaze layer adopting an oxide as a color former on the fired frit layer, and firing, and (4) finally carrying out drying, firing and polishing processing to obtain the finished product, wherein the curing agent contains, by mass, 5.0-6.0% of a cellulose thickener, 2.0-2.8% of attapulgite, 1.1-1.4% of a defoamer, 1.2-1.8% of a dispersing agent, and the balance of a solvent. According to the present invention, the frit particle binder of the present invention is suitable for the frit particles with the smaller particle (100-200 mesh), such that the frit particle is prevented from being sucked by the low negative pressure of the kiln preheating zone due to the small size during the glazed brick preparation process so as to avoid a large number of pin holes, bubbles and other defects on the ceramic brick surface, such that the glazed brick having the better decoration effect is obtained.
