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] Components of each 100kg of glass-ceramic frit particle fixative: 5.0kg of hydroxyethyl cellulose (purchased by Guangzhou Moke Building Materials Technology Co., Ltd.), 2.5kg of attapulgite, 1.1kg of polymethylsiloxane, silicone modified Sodium phosphate 1.7kg, the balance is water.

[0023] 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.

[0024] Preparation of adobe of glass-ceramic composite board-Example 1-...

Embodiment 2

[0041] 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 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.

Embodiment 2-1

[0043] The high-temperature transparent glass-ceramic frit particles (purchased from Quincy Carloby Glaze Company, 100-200 mesh) are placed on the surface of the green body through the printing process, and then one layer of glass-ceramic obtained in Example 2 is sprayed frit particle fixing agent, you can get the required adobe (such as figure 2 As shown, it includes a green body layer 1 and a glass-ceramic layer 4). This kind of adobe can be sent to the kiln for firing at 1170°C, and the edges are ground and chamfered to obtain a finished glass-ceramic composite board with uniform distribution and complete ice crystal texture. The brick adobe provided by the invention can avoid 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 Example 2-1 spread stably d...

Abstract

The invention relates to a green brick of a single-firing glass ceramic composite board. The green brick comprises a green body layer and a glass ceramic frit layer from bottom to top, and further comprises a fixing layer arranged on the surface of the glass ceramic frit layer, the fixing layer is formed by spraying a glass ceramic frit particle fixing agent, the glass ceramic frit particle fixing agent comprises the following components in percentage by weight: 5.0-6.0% of a vitamins thickener, 2.0-2.8% of attapulgite, 1.1-1.4% of a defoamer, 1.2-1.8% of a dispersing agent and the balance of a solvent. When the green brick is used, a glass ceramic frit particle on the surface cannot be taken away by an air draught in a preheating zone in the firing, so that the waste is avoided, and the defect rate of a product of the glass ceramic composite board 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 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...
