Abstract

The invention provides a production process of an ultrathin microcrystalline layer microcrystalline glass ceramic composite board, comprising the following steps: 1, preparing a low-temperature biscuiting high-water-absorption ceramic substrate; 2, printing or spraying a fixing agent on the ceramic substrate and then paving or printing a transparent glass smelting block, a semitransparent glass smelting block or an emulsion opal glass smelting block with the thickness of 1.0-3.5 mm; and pre-pressing and fixing; 3, carrying out glaze firing through a kiln to smelt the glass smelting block, and annealing and cooling to obtain a microcrystalline glass ceramic composite board semi-finished product; and 4, polishing, milling, checking and packaging the microcrystalline glass ceramic composite board semi-finished product to obtain a finished product. Compared with the prior art, preferable special microcrystalline glass smelting block cloth production process and sintering process are obtained through many times of optimized experiments; and the surface of the prepared ultrathin microcrystalline layer microcrystalline glass ceramic composite board has no air bubbles by visual contact and the crystallization degree is high, so that the microcrystalline glass ceramic composite board is more attractive. The production process has the advantages of low production cost, large capacity, high product quality, good appearance effect and the like, and has very strong market competitiveness.

Description

technical field [0001] The invention relates to a production process of an ultra-thin microcrystalline layer glass-ceramic composite plate, in particular to a production process method for reducing the thickness of the glass microcrystalline layer by changing the water absorption rate of the ceramic substrate, increasing production capacity, and reducing comprehensive production costs , belonging to the field of inorganic material production. Background technique [0002] Glass-ceramic composite board is a high-grade green building decoration material that has been successfully developed recently. It looks like stone but surpasses stone. It has high density, high flexural strength, high thermal stability, high wear resistance and other physical properties superior to natural stone; it looks like ceramic tile and is superior to ceramic tile. It does not have the color difference and dark cracks of stone, and it is not as easy to absorb dirt as ceramic tiles. [0003] Glass-...
