The invention provides a green
brick structure of a single fired
glass ceramic composite board. The green
brick structure comprises a green
brick body layer, a ground coat layer and a
glass ceramic frit layer from bottom to top, wherein a hydrophobic layer is also arranged between the green brick body layer and the ground coat layer; the
glass ceramic frit layer is formed by applying
microcrystalline frit particle suspension prepared by mixing glass
ceramic frit particles with a frit particle binder to the surface of the ground coat layer; the frit particle binder comprises the following components by
mass fraction: 5.5-6.5% of cellulosic thickening agents, 2.5-3.2% of white
carbon black, 1.1-1.4% of defoaming agent, 1.2-1.8% of dispersing agents and the balance of solvents. By using the green brick, the glass
ceramic frit particles on the surface can not be drawn away by a draught
fan in a preheating zone during firing, thus avoiding waste and reducing the defect rate of glass
ceramic composite board products.
