Problems solved by technology

[0003] The adobe of the glass-ceramic composite board fired at one time includes a green body layer, a bottom glaze layer and a glass-ceramic layer from bottom to top. The glass-ceramic layer is generally composed of glass-ceramic frit particles. The adobe is pressed, glazed and printed. Finally, a layer of glass-ceramic frit particles will be placed on the surface of the bottom glaze layer, and then sent to the kiln for firing. When transported into the kiln, it will pass through a low negative pressure pre-tropical zone. The glass-ceramic frit particles are easy to be sucked away because of their light weight, resulting in the lack of many glass-ceramic frit particles on the surface layer. It greatly affects the quality and aesthetics of the glass-ceramic composite board, and the qualified yield is not high

Embodiment 1

[0022] The components of each 100kg glass-ceramic frit particle fixing agent: hydroxyethyl cellulose (purchased by Guangzhou Moke Building Material Technology Co., Ltd.) 5.0kg, attapulgite 2.5kg, polymethylsiloxane 1.1kg, silicone modified 1.7 kg of sodium phosphate, the balance is water.

[0023] The preparation method of the above-mentioned frit particle binder includes the following steps: a) dissolving hydroxyethyl cellulose in water and stirring uniformly; b) adding polymethylsiloxane and organic silicon-modified sodium phosphate, and stirring uniformly; c) Add attapulgite and the remaining water solvent, stir evenly to obtain a frit granular binder, and measure its flow rate to be 26.8s (30°C, 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

[0041] The preparation method of this embodiment is basically the same as that of Embodiment 1, except that the components and ratios used in this embodiment are different. The components of each 100kg frit granule binder: hydroxyethyl methylcellulose (Dezhou Kangrong Chemical Co., Ltd.) 5.5kg, attapulgite 3.0kg, polymethylsiloxane 1.4kg, sodium hexametaphosphate 2.1 kg, the balance is ethanol.

Embodiment 2-1

[0043] Place high-temperature transparent glass-ceramic frit particles (purchased from Quincy Carrobie Glaze Company, 100-200 mesh) on the surface of the printed body, and then spray a layer of the glass-ceramic prepared in Example 2 Frit particle fixing agent, you can get the required bricks (such as figure 2 As shown, the body layer 1 and the glass-ceramic layer 4) are included. This kind of brick can be sent into a kiln to be fired at 1170°C, and the edges and corners are ground and chamfered to obtain a finished product of the glass-ceramic composite plate with uniform distribution and complete ice crystal texture. The bricks provided by the present invention can avoid the adverse effects (such as pinholes, lack of decorative effects, etc.) caused by the negative pressure of the preheating zone on the adsorption of frit particles during firing. It should be noted that the high-temperature transparent glass-ceramic frit particles selected in this embodiment 2-1 spread stab...

Abstract

An adobe for firing a glass-ceramics composite board at one time, the adobe includes a green body layer and a glass-ceramics frit layer from bottom to top, and also includes a fixing layer arranged on the surface of the glass-ceramics frit layer; The fixed layer is formed by spraying a glass-ceramic frit particle fixative, and the glass-ceramic frit particle fixative includes the mass fraction of the following components: vitamin thickener 5.0-6.0%, attapulgite 2.0-2.8% %, defoamer 1.1-1.4%, dispersant 1.2-1.8%, and the balance is solvent. Using this kind of adobe, the glass-ceramic frit particles on the surface will not be sucked away by the fan of the preheating zone during firing, thereby avoiding waste and reducing the defect rate of the glass-ceramic composite board product.

Description

Technical field [0001] The invention relates to the technical field of building ceramics, in particular to a brick blank for firing a glass-ceramic composite board at one time. Background technique [0002] Since the mature application of the glass-ceramic composite panel technology, its process technology has been continuously developed and innovated. The product has become a high-end decorative material on the market due to its transparent microcrystalline frit particle personalized decorative effect, and is well received by consumers favorite. [0003] The bricks of the once-fired glass-ceramic composite board include the body layer, the glaze layer and the glass-ceramic layer from bottom to top. The glass-ceramic layer is generally composed of glass-ceramic frit particles. The bricks are pressed and glaze printed Later, a layer of glass-ceramic frit particles will be placed on the surface of the bottom glaze layer, and then sent to the kiln for firing. When transported into th...
