Problems solved by technology

However, in production, the bricks with good cloth are sent to the kiln for preheating in a low negative pressure environment, and the fine particles (especially less than 100 mesh) are easily sucked away due to their light weight, and the glue covering the surface The fixative cannot play a good bonding and fixing effect on the glass-ceramic frit particles
In addition, if the use of glue fixative is applied to the production of once-fired glass-cera

Abstract

The invention provides a preparation method of a single fired glass ceramic composite board. The preparation method comprises the following steps: A, green body punch forming; B, spraying of a water repellent; C, glass ceramic frit applying: distributing and spreading the glass ceramic frits on the surface of a water repellent layer in the step B and spraying a layer of polyurethane fixing agents, wherein the polyurethane fixing agents are prepared from the following components by mass fraction: 6.5-7.5% of nonionic polyurethane associative thickening agent, 3.2-4.4% of white carbon black, 1-1.5% of defoaming agent, 0.3-1.3% of dispersing agents and the balance of solvents; D, firing, feeding the green body into a kiln and firing at a temperature of 1200-1300 DEG C; and E, polishing and grinding, thus obtaining the finished product of the glass ceramic composite board. The preparation method has the beneficial effects that the adverse effects of a preheating zone of the kiln on the adsorption effects of the glass ceramic frits can be avoided and the product yield can be increased; the effects of the fixing agents on the green body strength can be avoided by using the water repellent in the scheme.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a preparation method of a once-firing glass-ceramic composite board. Background technique [0002] The glass-ceramic composite board is a new type of composite board that combines a layer of glass-ceramic on the surface of the ceramic tile. Because the surface is a glass-ceramic layer, it is completely antifouling and easy to clean and maintain. At present, the glass-ceramic frit is mainly covered with a certain thickness of glass-ceramic frit (particle size is 15-150 mesh) on the body surface or glaze surface by means of cloth, and a layer of fixing agent is sprayed to fix the particles on the surface of the body. The surface of the green body is reprocessed after firing. The quality of the glass-ceramic frit directly determines the flatness of the brick and the decorative effect of the brick. The fixing agent used in the prior art is only ordinary glue and water. Mix...
