The invention discloses a preparation method of a one-step sintered glass-ceramic composite board. The preparation method comprises the following steps of A, carrying out impact molding on a green body; B, glazing and printing, namely after drying the green body obtained in the step A, cleaning the surface of the green body, spraying a ground coat, and printing in a way of inkjet printing, roller printing, silk screen printing or a combination of several selected from all the ways, wherein the ground coat contains 3-5% of pyrophyllite; C, applying glass-ceramic frits, namely spreading the glass-ceramic frits on the surface of the green body obtained in the step B, and spraying a layer of polyurethane fixing agent, wherein the polyurethane fixing agent is prepared from the following components in percentage by mass: 3.8-4.8% of nonionic polyurethane associative thickener, 1.8-2.4% of attapulgite clay, 0.6-1% of defoaming agent, 0.6-1.6% of dispersing agent and the balance of solvent; D, sintering, namely sintering in a kiln at the temperature of 1150-1250 DEG C; and E, polishing to obtain a finished product of the glass-ceramic composite board. By using the method, adverse effects caused by the adsorption effect of a preheating zone of the kiln to the glass-ceramic frits can be avoided, and the rate of finished products can be increased.

The invention discloses a green brick of a one-step sintered 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, wherein a hydrophobic layer is also arranged between the green body layer and the ground coat layer; the glass-ceramic frit layer is formed by applying a glass-ceramic frit particle suspension liquid formed by mixing glass-ceramic frit particles and a frit particle binding agent on the surface of the ground coat layer; and the frit particle binding agent comprises the following components in percentage by mass: 3.8-4.8% of nonionic polyurethane associative thickener, 1.8-2.4% of attapulgite clay, 0.6-1% of defoaming agent, 0.6-1.6% of dispersing agent and the balance of solvent. By using the green brick, the glass-ceramic frit particles on the surface cannot be taken away by a draught fan at a preheating zone when being sintered, so that the waste is avoided, and the defect rate of glass-ceramic composite board products is reduced.

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.
