Problems solved by technology

[0003] The adobe of the glass-ceramic composite board fired at one time includes a body layer, a bottom glaze layer and a glass-ceramic frit layer from bottom to top. The glass-ceramic frit layer is generally composed of glass-ceramic frit particles. Press molding to form the green body layer, after glaze printing, a layer of glass-ceramic frit particles will be spread on the surface of the bottom glaze layer, and then sent to the kiln for firing. When transported into the kiln, it will go through a low negative pressure preheating Belt, some small glass-ceramic frit particles on the uppermost layer are easily absorbed due to their light weight, resulting in the lack of many glass-ceramic frit particles on the surface layer, and the flatness of the adobe is not high after firing. Moreover, there are pinholes or dissolution holes, which greatly affect the quality and aesthetics of the glass-ceramic composite board, and the qualified yield is not high.

Embodiment 1

[0026] Components of per 100kg frit particle binder: hydroxyethyl cellulose (purchased by Guangzhou Moke Building Material Technology Co., Ltd.) 5.0kg, attapulgite 2.5kg, polymethylsiloxane 1.1kg, organosilicon modified phosphoric acid Sodium 1.7kg, the balance is water.

[0027] The preparation method of the above-mentioned frit granule binder comprises the following steps: a) dissolving hydroxyethyl cellulose in water, and stirring evenly; b) adding polymethylsiloxane and organic silicon-modified sodium phosphate, and stirring evenly; c) Add attapulgite and the remaining water solvent, and stir evenly to obtain a frit particle binder. The measured flow rate is 26.8s (30°C, coated with -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 1-1

[0029] The glass-ceramic frit particle of 375kg silver-white ice crystal effect (purchasing from Quincy Carroby Glaze Company, fineness 100-200 order) is added in the frit particle binder of 125kg that embodiment 1 makes, mixes Evenly, a suspension of glass-ceramic frit particles was obtained, the solid content of glass-ceramic frit particles was 75%, no visible bubbles, the flow rate was 44.7s (30°C, coated with -4 cups), and the suspension was still without stratification after standing for 5 days It can be seen that the frit particle binder of the present invention still has good stability after mixing with the glass-ceramic frit particles. It should be noted that the glass-ceramic frit particles with silver-white ice crystal effect selected in Example 1-1 spread during the sintering process, forming the effect of silver-white ice crystal flowers on the glaze layer, and the glass-ceramic frit particles It can be purchased through the color glaze company, and similar frit pr...

Embodiment 2

[0049] The preparation method of this example is basically the same as that of Example 1, the difference is that the components and proportions used in this example are different. The components of each 100kg frit particle binder: 5.5kg of hydroxyethyl methylcellulose (Dezhou Kangrong Chemical Co., Ltd.), 3.0kg of attapulgite, 1.4kg of polymethylsiloxane, and 2.1 kg of sodium hexametaphosphate kg, the balance being ethanol.

Abstract

The invention discloses a microcrystalline glass composite plate green brick formed by one-step sintering. The microcrystalline glass composite plate green brick comprises a green brick layer, a ground coat layer and a microcrystalline glass frit layer from bottom to top. The microcrystalline glass frit layer is formed by coating the surface of the ground coat layer with a microcrystalline glass frit particle suspension comprising microcrystalline glass frit particles and a microcrystalline glass frit particle binder. The microcrystalline glass frit particle binder comprises, by mass, 5.0-6.0% of a cellulose thickening agent, 2.0-2.8% of attapulgite, 1.1-1.4% of an antifoaming agent, 1.2-1.8% of a dispersant and the balance a solvent. The microcrystalline glass frit particles on the surface of the sintered green brick are not pumped by a fan of a preheating belt so that waste is avoided and a microcrystalline glass composite plate product defect rate is reduced.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a brick adobe made of a glass-ceramic composite plate fired once. Background technique [0002] Since the technology of glass-ceramic composite panel has been maturely applied, its technology has been continuously developed and innovated, and the product has become a high-grade decorative material in the market because of its transparent micro-crystalline frit particles and personalized decorative effect, and is well received by consumers. favorite. [0003] The adobe of the glass-ceramic composite board fired at one time includes a body layer, a bottom glaze layer and a glass-ceramic frit layer from bottom to top. The glass-ceramic frit layer is generally composed of glass-ceramic frit particles. Press molding to form the green body layer, and after glaze printing, a layer of glass-ceramic frit particles will be spread on the surface of the bottom glaze layer, an...
