The invention relates to a method for preparing a jadeite microcrystal
glass ceramic composite board, and relates to the technical field of building materials. The method comprises the following steps of: on the basis of a key technology of 'jadeite microcrystal glass clinker dry granules obtained by selecting materials within a preset range of product ingredients', applying a ground coat on a
ceramic blank to obtain a ground coat blank, and printing
textile printing
glaze on the ground coat blank to obtain an over-
glaze colored ceramic blank; applying the jadeite microcrystal glass clinker dry granules on the over-
glaze colored ceramic blank to obtain over-glaze
colored clinker dry granular greenware, spraying methylcellulose for fixing to obtain greenware to be fired; and firing the greenware to be fired to obtain a semi-finished product, strickling, calibrating thickness,
polishing coarsely,
polishing finely, edging, chamfering, airing, sorting, performing color separation, and grading to prepare a finished product of the jadeite microcrystal
glass ceramic composite board. The method is used for producing jadeite microcrystal
glass ceramic composite boards, and adapts to a primary or secondary
sintering process; and the product is high in quality, high in
surface strength and
wear resistance and wide in application range, and has a unique jadeite texture and a high comprehensive benefit.
