Problems solved by technology

However, its shortcomings, defects and disadvantages are: it does not have a unique jade texture, its surface strength and wear resistance are slightly poor, and its production process is either one-time firing or two-time firing instead of one-time firing or two-time firing. Adaptation and scope of application are limited

specific Embodiment approach 1

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in the accompanying drawings:

[0041] A preparation method of a jade glass-ceramic composite board:

[0042] ①. Preparation of jade glass-ceramic frit dry granules: quartz, potassium feldspar, albite, calcite, dolomite, barium carbonate, sodium carbonate, potassium carbonate, borax, boric acid, calcium phosphate each with a thickness of less than 100 mesh 80-700 kg is mixed evenly as raw materials and sent to the glass tank kiln for melting. The melting temperature is 1520-1600°C. 2 50-70%, Al 2 o 3 5-20%, CaO 0-10%, MgO 0-8%, K 2 O+Na 2 O 2-10%, BaO 0-8%, B 2 o 3 0-8%, P 2 o 5 0-5% and 30-200 mesh jade glass-ceramic frit dry granules with moisture <0.5% for use;

[0043] ②. Preparation of ceramic green body: 385-12250 kg each of kaolin, clay, quartz, potassium feldspar, albite, and talc with a particle size of less than 1 mm are mixed as cerami...

specific Embodiment approach 2

[0064] Carry out by specific embodiment one, just as shown in the accompanying drawing of description, just:

[0065] 1. In the preparation of the jade quality glass-ceramic frit dry granules of ①: press SiO 2 56.53%, Al 2 o 3 9.92%, CaO5.53%, MgO6.12%, K 2 O+Na 2 O 6.25%, BaO 5.86%, B 2 o 3 6.71%, P 2 o 5 3.08%, select the corresponding proportion of quartz, potassium feldspar, calcite, dolomite, soda ash, barium carbonate, boric acid, potassium nitrate, calcium phosphate, less than 100 mesh, for batching. Mix in a mixer for 30 minutes, melt in a pool kiln of 22 square meters, the melting temperature is 1580°C, and the storage time is about 24 hours. The clarified melt is water quenched, dried, crushed, and sieved , to obtain 30-200 mesh glass pellets. Then, through a dry distributing machine, evenly distribute the prepared jade glass-ceramic frit dry particles on the ceramic green body with printed patterns, and the cloth amount is 3.5-6Kg / m 2 , and then spraye...

specific Embodiment approach 3

[0068] Carry out by the step of specific embodiment one, but the difference with specific embodiment one lies in the prescription of jade glass-ceramic frit. The formula composition of its jade glass-ceramic frit is SiO 2 53.21%, Al 2 o 3 9.85%, CaO5.90%, MgO5.14%, K 2 O+Na 2 O 8.22%, BaO 7.56%, B 2 o 3 6.99%, P 2 o 5 3.13%. Also received the expected effect.

Abstract

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.

Description

technical field [0001] The preparation method of the jade glass-ceramic composite board of the present invention relates to the technical field of building materials; in particular to the technical field of glass ceramic building materials; especially to the technical field of production methods of glass-ceramic building material products; in particular to the preparation of jade glass-ceramic composite boards method technology field. Background technique [0002] At present, the surface of the overglaze transparent glass-ceramic composite board products that are popular in the market is compounded with a highly transparent dry glass material, which can clearly show the patterns on the surface of ceramic products, and has a high degree of stone simulation. , coupled with many advantages such as high gloss, anti-fouling and easy to clean, it has been favored by consumers in the past two or three years. However, its shortcomings, defects and disadvantages are: it does not hav...
