Embodiment 1

[0024] The components of the frit particle binder per 100kg: hydroxyethyl cellulose (purchased by Guangzhou Moke Building Materials Technology Co., Ltd.) 5.0kg, attapulgite 2.5kg, polymethylsiloxane 1.1kg, organosilicon modified phosphoric acid Sodium 1.7kg, the balance is water.

[0025] The preparation method of the frit granule binder includes 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 2

[0048] 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.) 5.5kg, attapulgite 3.0kg, polymethylsiloxane 1.4kg, sodium hexametaphosphate 2.1 kg, the balance being ethanol. The flow rate of the prepared frit particle binder is 25.7s (30°C, coated with -4 cups), and the kinematic viscosity value is 84.56 mm 2 / s.

[0049] Preparation of glass-ceramic composite board - Example 2-1

[0050] First pour a layer of silicone water repellent on the printed brick, and then spread a layer of transparent frit particles (purchased from Zibo Boshan Jinmingse Glaze Factory, fineness 130 mesh) and crystallization frit with ice crystal effect after firing. The mixture of block particles is then sprayed with a layer of frit particle binder obtained in Example 2, ...

Embodiment 3

[0054] 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. Components of per 100kg frit particle binder: hydroxypropyl methylcellulose (Dezhou Kangrong Chemical Co., Ltd.) 6.0kg, attapulgite 2.6 kg, polymethylsiloxane 1.2kg, sodium hexametaphosphate 1.8 kg, the balance is ethylene glycol. The flow rate of the prepared frit particle binder is 25.2s (30°C, coated with -4 cups), and the kinematic viscosity value is 84.98 mm 2 / s.

[0055] Preparation of glass-ceramic composite board - Example 3-1

[0056] First pour a layer of silicone water repellent on the printed brick, and then spread a layer of transparent frit particles (purchased from Zibo Boshan Jinmingse Glaze Factory, fineness 170 mesh) and crystallization frit with ice crystal effect after firing. The mixture of block particles is then sprayed with a layer of frit particle binder obtained in Examp...

Abstract

A microcrystalline glass ceramic composite panel production technology comprises the following steps: distributing powder for stamping to form a raw brick, forming a ground glaze layer, the forming a printing layer, spraying a water repellent, distributing frit particles, spraying a frit particle binder, firing, and finally polishing, grinding, inspecting and packing into a finished product; wherein the frit particle binder comprises the following components by weight: 5-6% of a cellulose thickening agent, 2-2.8% of attapulgite, 1.1-1.4% of a defoaming agent, 1.2-1.8% of a dispersant agent, and balance of a solvent. Through use of the frit particle binder, the defects of a large number of pinholes and bubbles and the like produced on ceramic tile surface can be avoided, and the defects are caused by the fact that the frit particles are sucked away by low negative pressure of a kiln preheating zone, completeness and smoothness of the surface of the firmed raw brick can be improved greatly, and a hydrophobic agent can alleviate the impact of a solvent in the frit particle binder on the raw brick body caused by infiltration of the solvent into the raw brick body.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production process of a glass-ceramic composite board. Background technique [0002] Glass-ceramic composite board is a high-end decorative building material product. It is crystal clear, elegant, naturally grown and varied stone-like texture, brightly colored layers, uncanny appearance decoration effect, and free from pollution, It is easy to clean, has excellent physical and chemical properties, and has stronger weather resistance and weather resistance than stone, so it is favored by high-end building materials markets at home and abroad. [0003] In the production process of glass-ceramic composite panels, the frit is inseparable; however, the quality of the frit particles directly determines the quality of the brick adobe decoration, because glue or methyl cellulose water can fix the transparent frit It is said that when firing, it is necessary to use frit part...
