The invention provides a green brick of a single fired glass ceramic composite board. The green brick comprises a green body layer, a ground coat layer and a glass ceramic frit layer from bottom to top and also comprises a fixed layer arranged on the surface of the glass ceramic frit layer, wherein the fixed layer is formed by spraying a glass ceramic frit particle fixing agent; the glass ceramic frit particle fixing agent comprises the following components by mass fraction: 5.0-6.0% of cellulosic thickening agents, 2.0-2.8% of attapulgite, 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.

The invention relates to a green brick of a monofired glass ceramic composite plate. The green brick comprises a green body layer and a glass ceramic frit layer from bottom to top, a water repellent layer is further arranged between the green body layer and the glass ceramic frit layer, and the glass ceramic frit layer is formed in the way that a glass ceramic frit particle suspension liquid formed by mixing glass ceramic frit particles and a frit particle adhesive is applied to the surface of the water repellent layer; the frit particle adhesive comprises the following components by mass percent: 6.5-7.5 percent of a nonionic polyurethane associative thickener, 3.2-4.4 percent of silica, 1-1.5 percent of a defoamer, 0.3-1.3 percent of a dispersant and the balance of solvent. The glass ceramic frit particles of the surface of the green brick structure are not taken away by a blower at a preheating zone during firing, so that waste is avoided and the defect rate of the glass ceramic composite plate product is reduced.

The invention provides a frit particle binder and a preparation method thereof. The frit particle binder comprises the following components by mass fraction: 3.8-4.8% of nonionic polyurethane associative thickening agent, 1.8-2.4% of attapulgite clay, 0.6-1% of defoaming agent, 0.6-1.6% of dispersing agents and the balance of solvents. A using method of the frit particle binder comprises the following steps: uniformly mixing frit particles with the frit particle binder and applying the mixture to the surface of a green body. The other using method of the frit particle binder comprises the following steps: firstly laying the frit particles on the surface of the green body according to a designed pattern and then spraying or glazing a layer of frit particle binder on the surfaces of frit particles. By adopting the frit particle binder provided by the invention, the problem that the frit particles face a preheating zone at low negative pressure and are easy to suck away when entering a kiln to be fired is solved. The preparation method of the frit particle binder is simple in production equipment and process. The prepared frit particle binder is neutral, so that PH fluctuation does not have effects on properties.
