Embodiment Construction

[0010] 1, the general technological process of the present invention is as follows:

[0011]

[0012] 2, the main process characteristics of the present invention are as follows:

[0013] a. Glaze printing is to use screen or roller printing to form a pattern on the green body, and then fire at a firing temperature of 1180-1230°C to form a printing layer;

[0014] b. The transparent frit is uniformly distributed by means of funnel blanking and roller compaction, with a thickness of 3mm-5mm;

[0015] c. After the printing layer of the transparent frit cloth, a fixative should be applied to fix the frit. Water in the fixative: viscosity adjusting agent = 99:1, and the amount of the fixative is 180-240g / m 2 .

Abstract

The invention relates to a preparation technique for the composite board of coloured glaze, belonging to the technical field of building ceramic tile preparation, which comprises the steps in sequence of sphere forming of blanks, spray drying, pressing, drying, glazing printing, first firing, separating, transparent frit distributing, second firing, polishing, edging, grading, packing and warehousing. The preparation technique is characterized in that: a) a screen or a drum is adopted for the glazing printing of a green body to form a plurality of patterns, then the first firing is conducted under the firing temperature of 1200 to 1255 DEG C to form a printing layer; b) the transparent frits are evenly distributed with the dry distributing method of funnel blanking and drum pressing, and the heights are 3 to 5 mm; c) the fixative is applied to fix the frits after distributing the transparent frits on the printing layer, and the amount of the fixative is 180 to 240 g / m<2> with the ratio of water to viscosity modifier being 99 : 1. Adopting the technical proposal, the preparation technique for the composite board of coloured glaze has the advantages of high surface finish of the ceramic tile, low water absorption, rich pattern colours and large product specification.

Description

Technical field: [0001] The invention relates to the technical field of preparation of architectural ceramic tiles, in particular to a preparation process of a glazed composite plate. Background technique: [0002] In the current domestic architectural ceramics industry, there are various types of ceramic tiles, and the varieties of designs and colors emerge in endlessly. However, in summary, there are several major series of polished tiles, antique tiles, glazed tiles (tiles), and glass-ceramic (including composite panels). Each of these varieties has its advantages and disadvantages. Polished tiles are majestic but slightly monotonous in color; antique bricks are rich in color but plain and dull; How to use advanced equipment and adopt innovative technology to produce a large-scale ceramic tile with rich patterns, colorful colors and noble decorative effects has always been the dream of ceramic industry people, and it is also a long-awaited high-end decoration market.
