Embodiment 1

[0024] The preparation of frit particle fixing agent: the component of every 100kg frit particle fixing agent: nonionic polyurethane associative thickener (Nae Woi Korea., Ltd. company, model HIRESOL85) 7.5kg, white carbon black 3.6kg, Polyether-type GPE defoamer (purchased from Hangzhou Feier Chemical Industry Co., Ltd.) 1.3kg, sodium tripolyphosphate 1kg, and ethanol as the balance.

[0025] Above-mentioned frit particle fixing agent is prepared according to the following steps:

[0026] A. Dissolve 3.6kg of white carbon black in part of ethanol and stir evenly;

[0027] B, add 7.5kg nonionic polyurethane associative thickener (Nae Woi Korea., Ltd. company, model HIRESOL85) and remaining ethanol, stir;

[0028] C, add polyether type GPE defoamer (purchase from Hangzhou Feier Chemical Industry Co., Ltd.) 1.3kg and sodium tripolyphosphate 1kg, stir evenly for 65min, obtain frit particle binder;

Embodiment 1-1

[0030] (1), prepare ceramic tile adobe;

[0031] (2), the ice crystal texture frit particles (purchased from Zizi Bo Huaci Glaze Co., Ltd., fineness 90 orders) are clothed on the surface of the brick adobe, then the frit particle fixing agent that one deck embodiment 1 makes is sprayed, and sent into Firing in a kiln at 1200°C for 90 minutes to form a frit layer;

[0032] (3) Glazing: Glazing is applied on the fired frit layer and fired, and the frit layer reacts with the kiln to obtain a natural gradient pattern during firing; it is glazed by pouring glaze, spraying glaze, throwing glaze or dry powder cloth One or at least two combinations of the glazes are used for glazing; the thickness of the glaze surface is about 0.5 mm; and the glaze contains 2% manganese oxide by mass (based on the amount of dry material).

[0033] (4) After drying, firing and polishing the ceramic tiles processed in the above steps, a pattern with a decorative effect can be formed on the glass layer ...

Embodiment 2

[0054] 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. The component of every 100kg frit particle fixing agent: nonionic polyurethane associative thickener (Nae Woi Korea., Ltd. company, model HIRESOL85) 7.0kg, white carbon black 3.8kg, polyether type GPE defoamer ( Purchased from Hangzhou Phil Chemical Industry Co., Ltd.) 1.3kg, sodium tripolyphosphate 0.3kg, and the balance was ethanol.

[0055] Preparation of glazed tile - embodiment 2

[0056] (1), prepare ceramic tile adobe;

[0057] (2), the high-temperature transparent frit granules (purchased from Zizi Bo Huaci Glaze Co., Ltd., fineness 70 orders) are clothed on the surface of the brick adobe, and then the frit granule fixing agent that one deck embodiment 2 makes is sprayed, and sent into Firing in a kiln at 1250°C for 80 minutes to form a frit layer;

[0058] (3) Glazing: Glazing is applied...

Abstract

The invention discloses a production method of a polished glazed brick. The production method comprises the following steps: (1) preparing a ceramic brick; (2) laying frit particles, spraying a fixing agent, and sintering to form a frit layer; (3) covering the sintered frit layer by a glaze layer taking oxide as a color former, and sintering; (4) drying, sintering and polishing to obtain the finished polished glazed brick, wherein the fixing agent comprises the following components in percentage by mass: 6.5%-7.5% of a nonionic polyurethane associative thickener, 3.2%-4.4% of white carbon black, 1%-1.5% of a defoamer, 0.3%-1.3% of a dispersant and the balance of a solvent. According to the production method, the frit particle fixing agent is suitable for relatively small frit particles (60-90 meshes), and the frit particles are prevented from being sucked away by low negative pressure of a preheating zone of a kiln due to excessively small particles in a process of preparing the polished glazed brick, so that the flaws such as a large amount of pinholes and air bubbles on the surface of the ceramic brick are avoided and the polished glazed brick with a relatively good decoration effect is obtained.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production method of glazed tiles. Background technique [0002] Polished glazed brick is a new architectural ceramic product in recent years. It is printed on the green brick, then applied with transparent glaze, fired in the kiln and then polished. Advantages, the product completely releases the implicitness of the matte and dark light of polished glazed tiles, solves the defect that half-polished tiles are easy to hide dirt, has the glossiness and porcelain hardness of polished tiles, and also has the glazed high imitation of antique tiles effect, as well as the rich printing effect of the porcelain glaze. Because the glaze layer of polished glazed tiles is relatively thin, usually only 0.5-1.5mm, and it needs to be polished and processed, it is very easy to expose the bottom, damage the printed pattern layer and cause defects, and the decorative effect of the pr...
