However, the quality of the frit particles directly determines the quality of the adobe decoration effect. Because the fixation of the transparent frit particles by the glue is poor, the transparent frit particles that are too small are easy to introduce pinholes or air bubbles during firing. More importantly, fine particles (especially less than 100 mesh) are easy to be sucked away in the preheating zone of the kiln due to low negative pressure due to their light weight, so the transparent ice crystal texture formed by the glazed ceramic tile products produced There are interval lines, discontinuous, and there are air bubbles

Embodiment 1
[0023] Components of per 100kg frit particle binder: hydroxyethyl cellulose (purchased by Guangzhou Moke Building Materials Technology Co., Ltd.) 5.5kg, white carbon black 2.5kg, polymethylsiloxane 1.1kg, organic silicon modified phosphoric acid Sodium 1.7kg, the balance is ethylene glycol.
[0024] The preparation method of the above-mentioned frit particle binder comprises the following steps: a) dissolving hydroxyethyl cellulose in ethylene glycol and stirring evenly; b) adding polymethylsiloxane and organosilicon-modified sodium phosphate, Stir evenly; c) Add white carbon black and the remaining ethylene glycol solvent, stir evenly to obtain a frit particle binder, and measure its flow rate to be 25.7s (30°C, coat -4 cups). It should be noted that the organosilicon-modified sodium phosphate can be replaced by sodium polyacrylate or sodium hexametaphosphate as a dispersant, and this solution can also be realized.

Embodiment 2
[0056] The preparation method of this example is basically the same as that of Example 1, the difference is that in this example, the components and proportions used are different. Components of per 100kg frit particle binder: hydroxyethyl methylcellulose (Dezhou Kangrong Chemical Co., Ltd.) 6.5kg, white carbon black 3.2kg, polymethylsiloxane 1.4kg, sodium hexametaphosphate 2.1 kg, the balance being ethanol.
Embodiment 2-1
[0057] Preparation of Glazed Tiles-Example 2-1 (Refer to Example 1-1)
[0058] (1), prepare ceramic tile adobe;
[0059] (2), apply color glaze slurry to frit surface, make frit surface and form color glaze wrapping layer;
[0060] (3), pour a layer of organic silicon water-repellent on the surface of the ceramic tile, and then lay the frit with the colored glaze wrapping layer on the ceramic tile;
[0061] (4), supplementary spray coating one deck of frit particle adhesive made by embodiment 2 on the ceramic tile, so that the frit of the color glaze wrapping layer deposited on the upper part is bonded and fixed on the ceramic tile superior;
[0062] (5) After drying, firing and polishing the ceramic tiles processed in the above steps, a patterned glazed ceramic tile product can be obtained.
[0063] It needs to be explained here that the ceramic tile adobe formulas used above are all conventional formulas known in the art, and can be appropriately selected according to the...

Abstract
The invention relates to a production method of a pattern glazed ceramic tile. The production method comprises the following steps: preparing a ceramic tile blank; preparing a color-glazed wrapper on the surface of a clinker; spraying a water repellent layer on the surface of the ceramic tile blank; then, paving and depositing the clinker with the color-glazed wrapper on the ceramic tile blank; then, supplementarily spraying a clinker particle adhesive; and finally, drying, firing and rubbing down to obtain a pattern glazed ceramic tile product. The clinker particle adhesive comprises the following components in percentage by mass: 5.5-6.5% of a cellulose thickener, 2.5-3.2% of white carbon black, 1.1-1.4% of a defoaming agent, 1.2-1.8% of a dispersant and the balance of a solvent. By using the clinker particle adhesive to fix the clinker with the color-glazed wrapper on the ceramic tile blank, the clinker particles which are too small are prevented from being drawn away by a negative pressure of a preheating zone of a kiln, thereby preventing flaws such as massive needle holes and air bubbles on the surface of the tile from influencing the decorative effect of the tile blank.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a method for producing patterned glazed ceramic tiles. Background technique [0002] With the development of frit particles with various decorative effects, the application of different decorative effects played by distributing frit particles on adobe is more and more favored by manufacturers, and the market it brings is also immeasurable. Therefore, frit particles are not only used in glass-ceramic composite panels, but also used in the production process of many glazed ceramic tiles to enhance the decorative effect of bricks. However, the quality of the frit particles directly determines the quality of the adobe decoration effect. Since the fixation of the transparent frit particles by glue is poor, when firing, too small transparent frit particles are easy to introduce pinholes or air bubbles. More importantly, fine particles (especially less than 100 mesh) are eas...
