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

Abstract

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, namely respectively distributing green body powder prepared according to a known formula and micropowder layer powder with the particle size of less than or equal to 200 meshes, and then, impacting to form the green body; B, applying glass-ceramic frits, namely spreading the glass-ceramic frits on the surface of the green body obtained in the step A, 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; C, sintering, namely sintering in a kiln at the temperature of 1150-1250 DEG C; and D, polishing, namely polishing and edging the product which is cooled after being sintered 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.

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 plate. 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...
