Abstract
The invention provides a green brick of a single fired glass ceramic composite board. The green brick comprises a green brick body layer, a ground coat layer and a glass ceramic frit layer from bottom to top, wherein the glass ceramic frit layer is formed by applying a 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.
Description
Technical field
The present invention relates to a kind of architectural pottery technical field, particularly relate to a kind of adobe of once-firing crystallite glass composite plate.
Background technology
Since the application of crystallite glass composite plate technology maturation, its Technology development is innovated, and product also due to the decorative effect that it has penetrating crystallite frit particle personalization, becomes the high-grade finishing material on market, deeply likes by consumers in general.
The adobe of the crystallite glass composite plate of once-firing comprises green body layer from bottom to top, ground glaze layer and glass ceramics frit layer, glass ceramics frit layer is generally by glass ceramics frit granulometric composition, the repressed shaping formation green body layer of adobe, can at ground glaze layer surface material distribution one deck glass ceramics frit particle after glazing stamp, send in kiln again and fire, when delivering into kiln, can through the preheating zone of a lower negative pressure, some clothes are easily sucked away in the fine microcrystalline glass frit particle of the superiors due to lighter weight, cause disappearance upper layer having many glass ceramics frit particles, it is not high that adobe burns out rear planeness, and have pin hole or dissolution pore to occur, extremely affect quality and the aesthetic property of crystallite glass composite plate, qualified yield rate is not high.
Summary of the invention
The object of the invention is to propose the high and adobe of the once-firing crystallite glass composite plate that planeness is high of a kind of qualified yield rate.
For reaching this object, the present invention by the following technical solutions:
A kind of adobe of once-firing crystallite glass composite plate, described adobe comprises green body layer, ground glaze layer and glass ceramics frit layer from bottom to top, and described glass ceramics frit layer is that the crystallite frit particle suspension liquid be mixed into by glass ceramics frit particle and frit granule agglomerant imposes on ground glaze layer surface and formed;
Described frit granule agglomerant comprises the massfraction of following component: cellulose thickener 5.5-6.5%, White Carbon black 2.5-3.2%, and defoamer is 1.1-1.4%, and dispersion agent is 1.2-1.8%, and surplus is solvent.
Preferably, between the glass-ceramic layer that the dilation coefficient of described ground glaze layer is formed after described green body layer and described glass ceramics frit melting.
Preferably, the granular size of described glass ceramics frit is 100-200 order.
Preferably, described crystallite frit particle suspension liquid adopts and drenches the surface that glaze mode imposes on ground glaze layer.
Preferably, the thickness that described crystallite frit particle suspension liquid imposes on described ground glaze layer surface is 1-4mm.
Preferably, the solid content of described crystallite frit particle suspension liquid is no less than 65%.
