Embodiment 1

[0029] Components of per 100kg frit particle binder: 5.5kg of hydroxyethyl cellulose (purchased by Guangzhou Moke Building Material Technology Co., Ltd.), 2.5kg of white carbon black, 1.1kg of polymethylsiloxane, organosilicon modified phosphoric acid Sodium 1.7kg, the balance is ethylene glycol.

[0030] The preparation method of the frit granule binder includes the following steps: a) dissolving hydroxyethyl cellulose in ethylene glycol and stirring evenly; b) adding polymethylsiloxane and organosilicon-modified sodium phosphate, Stir evenly; c) Add white carbon black and the remaining ethylene glycol solvent, stir evenly to obtain a frit particle binder, and measure its flow rate to be 25.7s (30°C, coat -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

[0055] 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.) 6.5kg, white carbon black 3.2kg, polymethylsiloxane 1.4kg, sodium hexametaphosphate 2.1 kg, the balance being ethanol.

[0056] Preparation of glass-ceramic composite board - Example 2-1

[0057] 375kg of transparent frit particles (purchased from Zibo Boshan Jinmingse Glaze Factory, fineness 110 orders) and the mixture of crystalline frit particles with ice crystal effect after burning are added to the frit particles of 125kg obtained in Example 1 for bonding In the agent, mix evenly to get a suspension of frit particles. The solid content of frit particles is 75%, no visible bubbles, and the flow rate is 46.8s (30°C, coated with -4 cups). There is still no stratification after the suspe...

Embodiment 3

[0062] 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, white carbon black 2.8kg, polymethylsiloxane 1.2kg, sodium hexametaphosphate 1.8 kg, the balance is ethylene glycol.

[0063] Preparation of glass-ceramic composite board - Example 3-1

[0064] 325kg of transparent frit particles (purchased from Zibo Boshan Jinmingse Glaze Factory, fineness 110 orders) and the mixture of crystalline frit particles with ice crystal effect after burning are added to the 175kg frit particles obtained in Example 3 for bonding In the agent, the solid content of frit particles is 65%, no visible bubbles, the flow rate is 44.8s (30°C, coated with -4 cups), and there is still no delamination phenomenon after the suspension is placed for 5 days. It can be s...

Abstract

The invention relates to a microcrystallite glass ceramic composite plate production process, which comprises: applying a powder material and stamping to form a brick billet; forming a bottom glaze layer, forming a printing layer, carrying out first firing, applying frit particles, carrying out second firing, and finally carrying out polishing, edging, inspection and packaging to obtain the finished product, wherein a suspension prepared from the frit particles and a frit particle binder is adopted as a binder, and the frit particle binder contains, by mass, 5.5-6.5% of a cellulose thickener, 2.5-3.2% of white carbon black, 1.1-1.4% of an anti-foaming agent, 1.2-1.8% of a dispersing agent, and the balance of a solvent. According to the present invention, the suspension prepared from the frit particles and the frit particle binder is adopted as the binder, such that the frit particle is prevented from being sucked by the low negative pressure of the kiln preheating zone so as to avoid a large number of pin holes, bubbles and other defects on the ceramic brick surface and substantially improve the integrity and the smoothness of the surface texture of the fired brick billet.

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...
