Embodiment 1

[0022] A new type of glass-ceramic composite plate, which is composed of glass-ceramic and ceramic plate blank, is characterized in that:

[0023] Glass-ceramic consists of the following components by weight:

[0024]

[0025] The clarifying agent is fluorite, and the crystal nucleating agent is zircon.

[0026] The ceramic slab green body is composed of the following components by weight:

[0027]

[0028]

[0029] The method for preparing the novel glass-ceramic composite plate is characterized in that:

[0030] a. Preparation of glass-ceramic:

[0031] Quartz, potassium feldspar, albite, calcite, talc, dolomite, barium carbonate, sodium carbonate, potassium carbonate, boric acid, borax and clarifying agents, nucleating agents and or without The mixture of colorants is mixed evenly and sent to the glass kiln for melting. The melting temperature is 1420°-1520°C. The melted melt is water-quenched, dried, screened, and broken into crystallites smaller than 10 mm wit...

Embodiment 2

[0036] A new type of glass-ceramic composite plate, which is composed of glass-ceramic and ceramic plate blank, is characterized in that:

[0037] Glass-ceramic consists of the following components by weight:

[0038]

[0039]

[0040] The clarifying agent is fluorite, and the crystal nucleating agent is zircon.

[0041] The ceramic slab green body is composed of the following components by weight:

[0042]

[0043] The preparation method of the novel glass-ceramic composite plate is the same as that of the first embodiment.

[0044] The present invention uses CaO and MgO as raw materials, which are widely distributed and low in price, and at the same time avoid using expensive ZnO as raw materials, so that the cost is low, and at the same time, CaO-MgO-Al is used. 2 O 3 -SiO 2 The glass-ceramic of the system makes it low cost and can achieve the same high surface tension and low viscosity.

Abstract

The invention discloses ingredients, manufacturing techniques and technological parameters of a novel microcrystal glass ceramic composite board. The novel microcrystal glass ceramic composite board is characterized in that the ingredients contain no zinc oxide. The ingredients comprise 50-65% of SiO2, 5-20% of Al2O3, 5-20% of CaO, 5-20% of MgO, 2-8% of K2O+Na2O, 0-1% Li2O, 2-8% of NaO, 3-8% B2O3 and balanced 5-20% of clarifying agent, nucleation agent and coloring agent. A pyroxene microcrystal phase is separated out from glass ceramics, the devitrification breaks through particle boundaries, and crystallization textures in various patterns are grown. The novel microcrystal glass ceramic composite board achieves purposes of low cost and high decorative art levels.

Description

technical field [0001] The invention belongs to the technical field of decorative building materials products, in particular to a novel glass-ceramic composite board, and also relates to a preparation method of the composite board. Background technique [0002] The glass-ceramic-ceramic composite board is a high-end decorative building material product that combines "the high-end decorative material of the 21st century" - glass-ceramic with ceramic bricks that can realize large-scale mechanized production and low cost. This kind of composite material is high in technology and difficult in production technology. Therefore, there are fewer than ten manufacturers that can achieve normal production. Guangdong Bode Jinggong Building Materials Co., Ltd. (hereinafter referred to as Bode Company) is one of them, and it ranks among the top manufacturers in terms of output, variety and quality. So far, except for Bode, other manufacturers can only produce CaO-Al 2 O 3 -SiO 2 Syste...
